1)第一種利用系統(tǒng)提供的api實現(xiàn)

Bitmap bitmap = BitmapFactory.decodeResource(getResources(), R.drawable.pic); //bitmap = Bitmap.createBitmap(100, 20, Config.ARGB_8888); BitmapDrawable drawable = new BitmapDrawable(bitmap); drawable.setTileModeXY(TileMode.REPEAT , TileMode.REPEAT ); drawable.setDither(true); view.setBackgroundDrawable(drawable);

2)第二種我們使用xml來輕松實現(xiàn)

<bitmap xmlns:android="" android:src="@drawable/img" android:tileMode="repeat" />

3)第三種自己畫出來

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; }
