1)第一种利用系统提供的api实现 view sourceprint? 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)第二种我们使用xml来轻松实现 <bitmap xmlns:Android="http://schemas.android.com/apk/res/android" android:src="../../@drawable/img" Android:tileMode="repeat" /> 3)第三种自己画出来 view sourceprint?01 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; }
