Question

我需要将图片加载到自定义对话框（扩展对话框的类）上的图像视图中。

在类中调用对话框，扩展对话框，让用户选择从图库加载图片或从相机拍照...到目前为止一切都很好！
然后startActivityForResult（）不是Dialog对象的一部分！并获得结果
onActivityResult（）也不属于Dialog类！

代码：

    package ....;

    .....

    public class AnosLeitura extends Dialog {

        ...

        public void btnImageLogo_OnClick(View v) {
            edLogo.setImageResource(R.drawable.no_image);
            final String[] option = new String[] { "From camera", 
                                                   "From gallery" };
            ArrayAdapter<String> adapter = new ArrayAdapter<String>(context,
                                           android.R.layout.select_dialog_item, option);
            AlertDialog.Builder builder = new AlertDialog.Builder(context);
            builder.setTitle("Choice");
            builder.setAdapter(adapter, new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialog, int which) {
                    if (which == 0) { callCamera(); }
                    if (which == 1) { callGallery(); }
                }
            });
            final AlertDialog dialog = builder.create();
            dialog.show();
        }

        ....

        public void callGallery() {
            Intent intent = new Intent();
            intent.setType("image/*");
            intent.setAction(Intent.ACTION_GET_CONTENT);
            intent.putExtra("crop", "true");
            intent.putExtra("aspectX", 0);
            intent.putExtra("aspectY", 0);
            intent.putExtra("outputX", 200);
            intent.putExtra("outputY", 150);
            intent.putExtra("return-data", true);

            //This is not possible!
            startActivityForResult(Intent.createChooser(intent, "Complete action using"),
                                              PICK_FROM_GALLERY);
        }

        // Neither this!
        @Override
        protected void onActivityResult(int requestCode, int resultCode, Intent data) {
            if (resultCode != RESULT_OK)
                return;

            switch (requestCode) {
                case CAMERA_REQUEST: 
                     Bundle extras = data.getExtras();
                     if (extras != null) {
                          Bitmap yourImage = extras.getParcelable("data");
                          ByteArrayOutputStream stream = new ByteArrayOutputStream();
                          yourImage.compress(Bitmap.CompressFormat.PNG, 100, stream);
                          imageInByte = stream.toByteArray();
                          edLogo.setImageBitmap(yourImage); 
                     }
                     break;
                case PICK_FROM_GALLERY: 
                     Bundle extras2 = data.getExtras();
                     if (extras2 != null) {
                          Bitmap yourImage = extras2.getParcelable("data");
                          ByteArrayOutputStream stream = new ByteArrayOutputStream();
                          yourImage.compress(Bitmap.CompressFormat.PNG, 100, stream);
                          imageInByte = stream.toByteArray();
                          edLogo.setImageBitmap(yourImage); 
                     }
                     break;
            }
     }

    ....

}

有谁知道一些解决方案？
