Question

我向Camera2Fragement类添加了一个新图像，以在警告对话框中显示位图图像，但我只得到没有任何图像的空对话框。我究竟做错了什么。它与我们无法将图像上传到图像视图或其他问题的片段有关。这是我的代码：

public void onClick(View view) {
        switch (view.getId()) {
            case R.id.picture: {
                takePicture();
                break;
            }
            case R.id.info: {
                Activity activity = getActivity();
                if (null != activity) {
                    new AlertDialog.Builder(activity)
                            .setMessage(R.string.intro_message)
                            .setPositiveButton(android.R.string.ok, null)
                            .show();
                }
                break;
            }
            case R.id.result: { // added code
                Activity activity = getActivity();
                if (null != activity) {

                    view = View.inflate(activity, R.layout.dialog_layout, null);

                    ImageView imgRefInflated = (ImageView) view.findViewById(R.id.dialog_imageview);

                    Picasso.with(activity).load("/mnt/sdcard/DCIM/mResultImg.jpg").into(imgRefInflated);
                    //imgRefInflated.setImageBitmap(BitmapFactory.decodeFile("/mnt/sdcard/DCIM/mResultImg.jpg"));
                    Log.d(TAG, "I can reach here");


                    AlertDialog.Builder builder = new AlertDialog.Builder(activity);

                    builder.setNegativeButton("Close", new DialogInterface.OnClickListener() {
                        @Override
                        public void onClick(DialogInterface dialog, int which) {
                            dialog.dismiss();
                        }
                    });

                    AlertDialog dialog = builder.create();
                    dialog.setView(view);
                    dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
                    dialog.show();

                }
                break;
            }
        }
    }

您正尝试将图像设置为AlertDialog内部的ImageView，但未显示。像这样重新安排你的代码：

view = View.inflate(activity, R.layout.dialog_layout, activity);

AlertDialog dialog = new AlertDialog.Builder(this)
        .setNegativeButton("Close", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                dialog.dismiss();
            }
        })
        .setView(view)
        .create();
dialog.show();
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);

ImageView imgRefInflated = (ImageView) view.findViewById(R.id.dialog_imageview);
Picasso.with(activity).load("/mnt/sdcard/DCIM/mResultImg.jpg").into(imgRefInflated);

在片段中的警报对话框中显示位图图像
