方法1： 系统api实现
复制代码 代码如下:
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);
方法2： XML实现
xml路径：res/drawable/bg.xml
复制代码 代码如下:
<bitmap xmlns:android="http://schemas.android.com/apk/res/android"
android:src="@drawable/img"
android:tileMode="repeat" />
方法3： 自定义绘制
复制代码 代码如下:
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;
}
