In last article, Using color in Android, by XML, described how to define color in XML file. Here, changing color using Java code will be described.



Keep using the main.xml and mycolor.xml

Modify Java code

package com.exercise.AndroidColor;

import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.LinearLayout;

public class AndroidColor extends Activity {
   /** Called when the activity is first created. */
   @Override
   public void onCreate(Bundle savedInstanceState) {
       super.onCreate(savedInstanceState);
       setContentView(R.layout.main);
      
       final LinearLayout backGround = (LinearLayout)findViewById(R.id.background);
       Button whiteButton = (Button)findViewById(R.id.whitebutton);
       Button redButton = (Button)findViewById(R.id.redbutton);
       Button greenButton = (Button)findViewById(R.id.greenbutton);
       Button blueButton = (Button)findViewById(R.id.bluebutton);
      
       whiteButton.setOnClickListener(new Button.OnClickListener(){
   @Override
   public void onClick(View v) {
    // TODO Auto-generated method stub
    backGround.setBackgroundResource(android.R.color.white);
   }});
      
       redButton.setOnClickListener(new Button.OnClickListener(){
   @Override
   public void onClick(View v) {
    // TODO Auto-generated method stub
    backGround.setBackgroundColor(0xff000000 + 0xff0000);
   }});
      
       greenButton.setOnClickListener(new Button.OnClickListener(){
   @Override
   public void onClick(View v) {
    // TODO Auto-generated method stub
    backGround.setBackgroundResource(R.color.green);
   }});
      
       blueButton.setOnClickListener(new Button.OnClickListener(){
   @Override
   public void onClick(View v) {
    // TODO Auto-generated method stub
    backGround.setBackgroundResource(R.color.blue);
   }});
   }
}

In Android, colors can be defined directly, such as "#ff0000" for red. You can also create a resource file under /res/values folder (with any file name), with your own color id defined inside. Such that you can access them in Java code using id. Android also defined a base set in android.R.color.

example:



/res/values/mycolor.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>
<color name="red">#ff0000</color>
<color name="green">#00ff00</color>
<color name="blue">#0000ff</color>
</resources>

/res/layout/main.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:id="@+id/background"
    >

<TextView  
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" 
    android:text="@string/hello"
    />
    
<!-- "white" defined in Android base set of colors -->
<Button
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content"  
    android:text="WHITE"
    android:textColor="@android:color/white"
    android:id="@+id/whitebutton"
 />
    
<!-- direct define textColor -->
<Button
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content"  
    android:text="RED"
    android:textColor="#ff0000"
    android:id="@+id/redbutton"
 />
 
<!-- "green" defined in mycolor.xml -->
<Button
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content"  
    android:text="GREEN"
    android:textColor="@color/green"
    android:id="@+id/greenbutton"
 />
 
<!-- "blue" defined in mycolor.xml -->
<Button
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content"  
    android:text="BLUE"
    android:textColor="@color/blue"
    android:id="@+id/bluebutton"
 />
</LinearLayout>

Create a class which extends Service, in that in onCreate(), create the mediaPlayer and if we need, we can provide a notification also, to notify the user that a background service is being activated.

In onStart(), start(), the mediaplayer also, set looping equals true. So that the mediaplayer will play continously

The complete code is

public class AudioService extends Service {

Mediaplayer player;
public void onCreate() {
player = MediaPlayer.create(this, R.raw.mj);
NotificationManager nm = (NotificationManager)getSystemService(Context.NOTIFICATION_SERVICE);
nOTIFICATION NOTIFICATION = new Notification(0, "Player started", System.currentTimeMillis());
nm.notify(0, notification);
try{
player.prepare();
} catch(Exception e){
}
}

public void onStart(Intent intent, int startId) {
 player.start();
player.setLooping(true);
}

public IBinder onBind(Intent intent) {
return null;
}
}
