ANDROID：删除“保存”和“丢弃”按钮

Question

如何在捕获图像后删除确认显示（＆＃39;保存＆＃39;以及＆＃39;丢弃＆＃39;按钮显示）？

我想在不更改应用程序功能的情况下删除第二步：在startActivityForResult函数之后转到previewCapturedImage()函数。

这是我的代码：

public class MainActivity extends Activity {

private static final int CAMERA_CAPTURE_IMAGE_REQUEST_CODE = 100;
public static final int MEDIA_TYPE_IMAGE = 1;
private static final String IMAGE_DIRECTORY_NAME = "OpenCV Demo";
private Uri fileUri;

private ImageView imgPreview;
private Button btnCapturePicture;
private FrameLayout  frameLayout;
private TextView textView;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    if (!OpenCVLoader.initAsync(OpenCVLoader.OPENCV_VERSION_2_4_8, this, mOpenCVCallBack))
    {
        Log.e("TEST", "Cannot connect to OpenCV Manager");
    }
    setContentView(R.layout.activity_main);
}

private void captureImage() {
    Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);

    fileUri = getOutputMediaFileUri(MEDIA_TYPE_IMAGE);

    intent.putExtra(MediaStore.EXTRA_OUTPUT, fileUri);

    // start the image capture Intent
    startActivityForResult(intent, CAMERA_CAPTURE_IMAGE_REQUEST_CODE);
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    // if the result is capturing Image
    if (requestCode == CAMERA_CAPTURE_IMAGE_REQUEST_CODE) {
        if (resultCode == RESULT_OK) {
            // successfully captured the image
            // display it in image view
            previewCapturedImage();
        } else if (resultCode == RESULT_CANCELED) {
            // user cancelled Image capture
            Toast.makeText(getApplicationContext(),
                    "User cancelled image capture", Toast.LENGTH_SHORT)
                    .show();
        } else {
            // failed to capture image
            Toast.makeText(getApplicationContext(),
                    "Sorry! Failed to capture image", Toast.LENGTH_SHORT)
                    .show();
        }
    }
}
private void previewCapturedImage() {
       //TODO something
    }

如何在捕获图像后删除确认显示（'保存'和'丢弃'按钮显示）？

你做不到。那不是你的应用程序。这来自用户选择的处理ACTION_IMAGE_CAPTURE的活动。该活动来自其他开发人员的应用程序，欢迎开发人员做任何开发人员想要的事情。如果您希望将照片委托给第三方应用程序，那么您将不得不忍受该第三方应用程序希望拍摄该照片。
