Three methods to achieve Android tile Effect

There are several methods to achieve tile effect.

First, use the api provided by the system:

 
 

  
  
Bitmap bitmap = BitmapFactory.decodeResource(getResources(), R.drawable.pic); 
  
  
 
  
  
//bitmap = Bitmap.createBitmap(200, 30, Config.ARGB_8888); 
  
  
BitmapDrawable drawable = new BitmapDrawable(bitmap); 
  
  
drawable.setTileModeXY(TileMode.REPEAT , TileMode.REPEAT ); 
  
  
drawable.setDither(true); 
  
  
view.setBackgroundDrawable(drawable);  
 
 

Second, it is easy to implement using xml, which may appear after 4.0:

 
 

  
  
<bitmap xmlns:Android="http://schemas.android.com/apk/res/android"    
  
  
android:src="../../@drawable/img" 
  
  
Android:tileMode="repeat" />  
 
 

Third, draw it by yourself:

 
 

  
  
public static Bitmap createRepeater(int width, Bitmap src){ 
  
  
int count = (width + src.getWidth() - 1) / src.getWidth(); 
  
  
 
  
  
Bitmap bitmap = Bitmap.createBitmap(width, src.getHeight(), Config.ARGB_8888); 
  
  
Canvas canvas = new Canvas(bitmap); 
  
  
 
  
  
    for(int idx = 0; idx < count; ++ idx){ 
  
  
        canvas.drawBitmap(src, idx * src.getWidth(), 0, null); 
  
  
     } 
  
  
 
  
  
     return bitmap; 
  
  
}
