如何裁剪位图？

Question

我已经从片段中检索了位图，并且我将位图（解码的字节数组）放置在 Imageview 中，我想裁剪此位图

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {
    View view = inflater.inflate(R.layout.fr_editcrop, container, false);


    cropphoto = (ImageView)view.findViewById(R.id.cropphoto);
    title = (TextView)view.findViewById(R.id.title);
    title.setText("Crop");

    crop = (Button)view.findViewById(R.id.crop);
    cancel = (Button)view.findViewById(R.id.cancel);

    tmp = getArguments().getString("PHOTO");

    byte [] encodeByte=Base64.decode(tmp,Base64.DEFAULT);
    bmp=BitmapFactory.decodeByteArray(encodeByte, 0, encodeByte.length);
    cropphoto.setImageBitmap(bmp);

    Width = cropphoto.getWidth();
    Height = cropphoto.getHeight();

Answer 1

称呼Bitmap.createBitmap(Bitmap source, int x, int y, int width, int height)
