                                               Progress bars are used to show progress of a task. For example. When you are uploading or downloading something from the internet, it is better to show the progress of download/upload to the user.Now here am going to customize the  progress bar

How to customize the progress bar?
                                To customize the progress bar we need to define the properties of progress bar which are defined in  the xml file inside the drawable folder.


1.Open Eclipse IDE.
2.Click File -> New -> Project -> Android Application Project.
3.Enter the name of the application  as CustomizedProgressbar and click next .
4.Make sure that you have enabled the create project in workspace.
5.Design application launcher icon and create a blank activity workspace and click finish 
6.Create a folder drawable inside the res folder
7.Create a custom_progressbar.xml inside the drawable folder

The custom_progressbar.xml coding is given below:

<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >

<!-- Define the background properties like color etc -->

<item android:id="@android:id/background">

<shape>

<gradient

android:angle="270"

android:centerColor="#0b131e"

android:centerY="1.0"

android:endColor="#0d1522"

android:startColor="#000001" />

</shape>

</item>

<!-- Define the progress properties like start color, end color etc -->

<item android:id="@android:id/progress">

<clip>

<shape>

<gradient

android:angle="270"

android:centerColor="#007A00"

android:centerY="1.0"

android:endColor="#06101d"

android:startColor="#007A00" />

</shape>

</clip>

</item>

</layer-list>

The activity_main.xml code is given below:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

xmlns:tools="http://schemas.android.com/tools"

android:background="#B4E0E1"

android:layout_width="match_parent"

android:layout_height="match_parent" >

<TextView

android:id="@+id/textView1"

android:layout_width="match_parent"

android:layout_height="wrap_content"

android:gravity="center"

android:layout_marginTop="80dp"

android:text="CustomizedProgressbar"

android:textAppearance="?android:attr/textAppearanceLarge"/>

<Button

android:id="@+id/button1"

android:layout_marginTop="150dp"

android:background="@drawable/button"

android:layout_width="fill_parent"

android:layout_height="wrap_content"

android:text="Start Downloading File"

android:onClick="startProgressDialog"/>

</RelativeLayout>

The activity_main.xml looks as shown below:

                                                                               

The MainActivity java as shown below :

package com.example.customizedprogressbar;


import android.support.v7.app.ActionBarActivity;
import android.app.ProgressDialog;
import android.graphics.drawable.Drawable;
import android.os.Bundle;
import android.os.Handler;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;


public class MainActivity extends ActionBarActivity
{


ProgressDialog progressBar;
private int progressBarStatus = 0;
private Handler progressBarHandler = new Handler();


private long fileSize = 0;

@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}


public void startProgressDialog(View V)
{



// prepare for a progress bar dialog
progressBar = new ProgressDialog(V.getContext());
progressBar.setCancelable(true);
progressBar.setMessage("Downloading File...");
progressBar.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
progressBar.setProgress(0);
progressBar.setMax(100);

// Get the Drawable custom_progressbar
Drawable customDrawable= getResources().getDrawable(R.drawable.custom_progressbar);

// set the drawable as progress drawable


progressBar.setProgressDrawable(customDrawable);

progressBar.show();


//reset progress bar status
progressBarStatus = 0;


//reset filesize
fileSize = 0;


new Thread(new Runnable() {
public void run() {
while (progressBarStatus < 100) {


// process some tasks
progressBarStatus = fileDownloadStatus();


// sleep 1 second to show the progress
try {
Thread.sleep(1000);
}
catch (InterruptedException e) {
e.printStackTrace();
}


// Update the progress bar
progressBarHandler.post(new Runnable() {
public void run() {
progressBar.setProgress(progressBarStatus);
}
});
}


// when, file is downloaded 100%,
if (progressBarStatus >= 100) {


// sleep for 2 seconds, so that you can see the 100% of file download
try {
Thread.sleep(2000);
} catch (InterruptedException e) {
e.printStackTrace();
}


// close the progress bar dialog
progressBar.dismiss();
}
}
}).start();


}





//method returns the % of file downloaded
public int fileDownloadStatus()
{


while (fileSize <= 1000000) {


fileSize++;


if (fileSize == 100000) {
return 10;
} else if (fileSize == 200000) {
return 20;
} else if (fileSize == 300000) {
return 30;
}
else if (fileSize == 400000) {
return 40;
} else if (fileSize == 500000) {
return 50;
} else if (fileSize == 600000) {
return 60;
}
// write your code here


}


return 100;

Using Custom Fonts in Android

Using Custom Fonts in Android
                                     

Here you are going to know that how to use external fonts in Android

1.Open Eclipse IDE.
2.Click File -> New -> Project -> Android Application Project.
3.Enter the name of the application  as openactivity and click next .
4.Make sure that you have enabled the create project in workspace.
5.Design application launcher icon and create a blank activity workspace and click finish 

Now you need to design your xml file .

Activity_main.xml

Here is the coding of activity_main.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:gravity="center"
    tools:context="com.example.androidcustomfont.MainActivity" >

    <TextView
        android:id="@+id/textView1"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:gravity="center"
        android:text="@string/mobile"
        android:textSize="35sp" />

    <TextView
        android:id="@+id/textView2"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_below="@+id/textView1"
        android:gravity="center"
        android:text="@string/And"
        android:textSize="35sp" />

</RelativeLayout>

Asset

 We are going to access the fonts using this asset folder ,create a new folder under asset and named it as fonts and copy the font you needed  inside the fonts folder as shown below.

                                               

String.xml

The string.xml file is shown below the value for the textview is passed through the string.

<?xml version="1.0" encoding="utf-8"?>
<resources>

    <string name="app_name">AndroidCustomFont</string>
    <string name="hello_world">Hello world!</string>
    <string name="action_settings">Settings</string>
    <string name="mobile">Mobileapptechnology</string>
    <string name="And">Android</string>

</resources>

MainActivity.java

Here the coding of MainActivity.java here we going to set the fonts to the textview which we copied it in the fonts folder under asset. 

package com.example.androidcustomfont;

import android.support.v7.app.ActionBarActivity;
import android.graphics.Typeface;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.widget.TextView;


public class MainActivity extends ActionBarActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        TextView tx = (TextView)findViewById(R.id.textView1);
        TextView tx1 =(TextView)findViewById(R.id.textView2);
        Typeface tf1= Typeface.createFromAsset(getAssets(), "fonts/complex.ttf");
        tx1.setTypeface(tf1);
        Typeface tf= Typeface.createFromAsset(getAssets(), "fonts/Disguise.otf");
        tx.setTypeface(tf);
    }


    }

The typeface class specify the typeface and style of the font like 

text size and specify how the text appears in the UI.

Now Run the application in emulator you will get the output as 

shown below.

Opening an activity in a button click in Android

Opening an Activity in a button click in Android

                                             

In this article you are going to learn about how to open an activity using Explicit intent.

1.Open Eclipse IDE
2.Click File -> New -> Project -> Android Application Project
3.Enter the name of the application  as openactivity and click next 
4.Make sure that you have enabled the create project in workspace
5.Design application launcher icon and create a blank activity workspace and click finish 

Now you need to design your xml file ,xml file is the layout where we design our User Interface.

activity_main.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
tools:context="com.mobileapptechnology.openactivity.MainActivity" >

    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:gravity="center"
        android:layout_marginTop="150dp"
       android:orientation="vertical" >

        <Button
            android:id="@+id/button1"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:background="@drawable/download"
            android:text="" />

    </RelativeLayout>

</RelativeLayout>

In the eclipse the activity_main.xml is present  under the res/layout/activity_main.xml.

In this layout you have to place a button as shown above, i had placed a image  as the background of the button.

After this now you have create a another xml file for the second activity.

so right click on the layout folder and click new and select android xml file ,they layout folder is present under the res folder.name the new xml as secondactivity.xml
String.xml
Normally in Android application whatever the values you are going to give will be provided in a proper manner.
Hardcore values could not be used in the application

<?xml version="1.0" encoding="utf-8"?>
<resources>

    <string name="app_name">OpenActivity</string>
    <string name="hello_world">Hello world!</string>
    <string name="action_settings">Settings</string>
    <string name="hai">Hai Friends</string>

</resources>

In  this application we set the value for the text view through the string.xml only as shown above.
the string.xml is under the values folder which is under the res folder.

Secondactivity.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="#67C1E6"
    android:orientation="vertical" >

    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginTop="150dp" >

        <TextView
            android:id="@+id/textView1"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:gravity="center"
            android:textSize="20sp"
            android:textColor="#FFFFFF"
            android:textStyle="italic"
            android:text="@string/hai" />

    </RelativeLayout>

</RelativeLayout>

In this layout i had placed a textview just to represent a text.in textview i mentioned the style ,size and color for it.and i give the gravity as center to place the text in the center of the screen.

MainActivity.java

Now its time to code the MainActivity as shown below

package com.mobileapptechnology.openactivity;

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.TextView;

public class MainActivity extends Activity {
 @Override
 protected void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.activity_main);
  Button but1=(Button)findViewById(R.id.button1);
  TextView text=(TextView)findViewById(R.id.textView1);
  but1.setOnClickListener(new OnClickListener() {
   
   @Override
   public void onClick(View v) {
    // TODO Auto-generated method stub
    Intent i= new Intent(getApplicationContext(),SecondActivity.class);
    startActivity(i);
   }
  });
 }

 
}

In MainActivity.java i have initialized the textview and button as shown above,after that am creating a on click event for the button to set the action for the button.

Here is used the explicit intent to open an activity from an activity when a button is clicked.

Here the getApplicationContext() refers the current class that 

means it refers the main activity.and the SecondActivity.class file 

refers the SecondActivity.java which is mentioned below.Before 

coding the MainActivity  we have to create a SecondActivity it 

means we have to create a new class by right clicking the package 

under the src folder and click the new and select the class give the 

name as SecondActivity.

SecondActivity.java

package com.mobileapptechnology.openactivity;

import android.app.Activity;
import android.os.Bundle;

public class SecondActivity extends Activity{
 protected void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.secondactivity);
}
}

In this SecondActivity we are going to link the secondactivity.xml file with the SecondActivity.java here we just mentioning the layout file .It is highlighted in the above code.

After that you have mention your SecondActivity.java in Manifest file ,Because Each and every activiy which we are newly creating has to be mentioned in Manifest file .Without initializing it the application will be filled with errors.

OpenActivtyManifest.

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.mobileapptechnology.openactivity"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk
        android:minSdkVersion="8"
        android:targetSdkVersion="21" />

    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <activity
            android:name=".MainActivity"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <activity android:name="com.mobileapptechnology.openactivity.SecondActivity"></activity>
    </application>

</manifest>

The text which is in bold represent  that the SecondActivity is mentioned in the Manifest File.by default the MainActivity is mentioned in Manifest file.

Now its time to run the application,you will get the output in your emulator as shown below .

When you click the button in the UI it will redirect you the SecondActivity as shown below.

Intents

Intent:

            1) Intent is a instant action.

                        2) Intent is a message  that is passed between the components(such as                    activity,content provider,services and content provider).

                          

                        3) Normally intents are used to pass the values between activity and to go from one activity to  another activity.

The main use of intent :

                       1)Start the service 

                       2)Launch the activity

                       3)Display a web page

                       4)Broadcast a message

                       5)Dial a  phone call

Types of Intents:

                 There are two types of intents in android ,they are 

                              

                       1)Implicit Intent

                       2)Explicit Intent

                                                                         

Implicit Intent

                 Implicit intents are used to provide the information of available components provided by the system that to be invoked.

                         For example you can use implicit intent coding  to view a webpage.

Intent i = new Intent(Intent.ACTION_VIEW, Uri.parse("http://www.mobileapptechnology.blogspot.com"));
startActivity(i); 

Explicit Intent 
                 Explicit intents are used to provide the external class,used to move from one activity to other activity.

                        For example you can use the following code  to move from one activity to another activity.

Intent i = new Intent(getApplicationContext(), ActivityTwo.class);  
startActivity(i);
