Question

我需要在相机屏幕上显示一个警告对话框，要求继续或退出相机我使用了system dialog，它在相机屏幕上打开，继续我关闭对话框，但在退出时我需要关闭相机屏幕并返回我的应用程序。

我正在使用此意图打开相机

String fileName = "testphoto.jpg";
        ContentValues values = new ContentValues();
        values.put(MediaStore.Images.Media.TITLE, fileName);
        values.put(MediaStore.Images.Media.DESCRIPTION, "Image capture by camera");
        values.put(MediaStore.Images.Media.MIME_TYPE, "image/jpeg");
        imageUri = getActivity().getContentResolver().insert(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values);
        Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
        intent.putExtra(MediaStore.EXTRA_OUTPUT, imageUri);
        intent.putExtra(MediaStore.EXTRA_VIDEO_QUALITY, 1);
        startActivityForResult(intent, Constants.SELECT_CAMERA_PHOTO);

用于系统对话框的代码

             final WindowManager manager = (WindowManager) getActivity().getApplicationContext().getSystemService(Context.WINDOW_SERVICE);
                WindowManager.LayoutParams layoutParams = new WindowManager.LayoutParams();
                layoutParams.gravity = Gravity.CENTER;
                layoutParams.type = WindowManager.LayoutParams.TYPE_SYSTEM_ALERT;
                layoutParams.width = WindowManager.LayoutParams.WRAP_CONTENT;
                layoutParams.height = WindowManager.LayoutParams.WRAP_CONTENT;
                layoutParams.alpha = 1.0f;
                layoutParams.packageName = getActivity().getPackageName();
                layoutParams.buttonBrightness = 1f;
                layoutParams.windowAnimations = android.R.style.Animation_Dialog;

                final View view = View.inflate(getActivity().getApplicationContext(),R.layout.system_alert_dialog, null);
                ButtonFlat yesButton = (ButtonFlat) view.findViewById(R.id.cancel_button);
                ButtonFlat noButton = (ButtonFlat) view.findViewById(R.id.confirm_button);
                TextView message = (TextView)view.findViewById(R.id.title_text);

                message.setText("Click you first image to see how it works.");

                yesButton.setOnClickListener(new View.OnClickListener() {

                    @Override
                    public void onClick(View v) {
                        manager.removeView(view);
                    }
                });
                noButton.setOnClickListener(new View.OnClickListener() {

                    @Override
                    public void onClick(View v) {
                        manager.removeView(view);
                       //==here camera should close==
                    }
                });
                manager.addView(view, layoutParams);

任何建议我该怎么做。

在noButton上使用2个替代finish();：

使用当前上下文设置setResult(Activity.RESULT.CANCELLED);。
设置next.titleReceived == titleF.text
