推荐答案
这并不容易。
一个解决办法是从删除您的图像,如下面的代码片段中不需要的像素此线程(关闭削减右上角):
One solution would be to remove the unwanted pixel of your image like the following snippet from this thread (cuts off the top right corner):
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
ImageView iv = (ImageView) findViewById(R.id.your_image);
int drawableId = R.drawable.your_drawable;
cutOffTopRightCorner(iv, drawableId, skewWidth);
}
@SuppressLint("NewApi")
private void cutOffTopRightCorner(ImageView iv, int resId, int skewWidth) {
Bitmap bm = BitmapFactory.decodeResource(getResources(), resId).copy(Config.ARGB_8888, true);
bm.setHasAlpha(true);
final int bmWidth = bm.getWidth();
for (int i = bmWidth; i > bmWidth - skewWidth; --i) {
for (int k = 0; k < i - (bmWidth - skewWidth); ++k) {
bm.setPixel(i - 1, k, Color.TRANSPARENT);
}
}
iv.setImageBitmap(bm);
}
另一个解决方案是用FrameLayouts工作(differenz Z-指数),并与其他图像或可绘制叠加图像。
Another solution would be to work with FrameLayouts (differenz z-indices) and to overlay your images with other images or drawables.
