Android 图片平铺效果bit地图

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="../..[email protected]/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;   }
