我正在试图弄清楚如何在使用相机意图时从相机获取图像。

当尝试捕捉图像时,照片应用程序或相机活动仍然存在,它不会返回我的其他应用程序,其中应该显示捕获的照片。

        public void onClick(View v) {
            // TODO Auto-generated method stub

            switch (v.getId()){
            case R.id.photo_camera_button:
                Intent photoIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
                startActivityForResult(photoIntent, CAMERA_PHOTO_REQUEST);
            break;
            case R.id.video_camera_button:
                Intent videoIntent = new Intent(android.provider.MediaStore.ACTION_VIDEO_CAPTURE);
                startActivityForResult(videoIntent, CAMERA_VIDEO_REQUEST);
            break;
            }
        }

   protected void onActivityResult(int requestCode, int resultCode, Intent data){
        super.onActivityResult(requestCode, resultCode, data);
        if(resultCode == RESULT_OK){
            if(requestCode == CAMERA_PHOTO_REQUEST){
                Bundle extras = data.getExtras();
                Bitmap bmp = (Bitmap) extras.get("data");
                ImageView imv = (ImageView) findViewById(R.id.ReturnedImageView);
                imv.setImageBitmap(bmp);
                //HttpGetMethod client = new HttpGetMethod();

            }
            if(requestCode == CAMERA_VIDEO_REQUEST){

                Context context1 = getApplicationContext();
                CharSequence text1 = "Video!";
                int duration1 = Toast.LENGTH_LONG;

                Toast toast1 = Toast.makeText(context1, text1, duration1);
                toast1.show();

            }
        }
    }

在我的xml中,我有ImageView

<ImageView
        android:id="@+id/ReturnedImageView"
        android:layout_width="250dp"
        android:layout_height="250dp"
        android:src="@drawable/ic_launcher" />

用户点击photo_camera_button,相机意图活动显示,我可以拍照,保存,删除,做我相机所做的所有事情。问题是,当我使用相机活动保存或拍照时,它不会返回原来的应用程序,或者如果我点击手机上的后退按钮,它就不显示了?

提前谢谢!
