Question

我的目标是为我的app设置圆形个人资料照片。用户可以裁剪图像并将其作为个人资料照片。我的代码可以裁剪图片，但无法将其放在图像视图中。请帮助！请找到以下代码：

    Intent photoPickerIntent = new Intent(Intent.ACTION_PICK,
            android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
            photoPickerIntent.setType("image/*");
            photoPickerIntent.putExtra("crop", "true");
            photoPickerIntent.putExtra("return-data", true);
            photoPickerIntent.putExtra("outputFormat", Bitmap.CompressFormat.JPEG.toString());
            startActivityForResult(photoPickerIntent,SELECT_PICTURE_PROFILE);
}

        protected void onActivityResult(int requestCode, int resultCode, Intent imageReturnedIntent, Intent data) {

                super.onActivityResult(requestCode, resultCode, imageReturnedIntent);

                switch (requestCode) {
                    case SELECT_PICTURE_PROFILE:
                        if (resultCode == RESULT_OK) {  
                            if (imageReturnedIntent!=null) {
                                Bundle extras = imageReturnedIntent.getExtras();
                                Bitmap selectedBitmap = extras.getParcelable("data");

                                BitmapDrawable bd=new BitmapDrawable(getResources(), selectedBitmap);
                                imageViewRound = (ImageView) findViewById(R.id.cimgv1);
                                imageViewRound.setImageDrawable(bd);

                            }
                        }
                }

   public static Bitmap getCroppedBitmap(Bitmap bitmap) {


        Bitmap output = Bitmap.createBitmap(bitmap.getWidth(),
                bitmap.getHeight(), Bitmap.Config.ARGB_8888);
        Canvas canvas = new Canvas(output);

        final int color = 0xff424242;
        final Paint paint = new Paint();
        final Rect rect = new Rect(0, 0, bitmap.getWidth(), bitmap.getHeight());

        paint.setAntiAlias(true);
        canvas.drawARGB(0, 0, 0, 0);
        paint.setColor(color);
        // canvas.drawRoundRect(rectF, roundPx, roundPx, paint);
        canvas.drawCircle(bitmap.getWidth() / 2, bitmap.getHeight() / 2,
                bitmap.getWidth() / 2, paint);
        paint.setXfermode(new PorterDuffXfermode(PorterDuff.Mode.SRC_IN));
        canvas.drawBitmap(bitmap, rect, rect, paint);
        //Bitmap _bmp = Bitmap.createScaledBitmap(output, 60, 60, false);
        //return _bmp;
        return output;
    }

使用此功能获取裁剪图像。

裁剪图像并将其放在android中的图像视图中
