android - 在android中单击相机后无需按确定按钮即可从相机获取图像

Question

我编写了从相机捕获图像的代码，它工作正常，捕获图像后，它要求在相机中单击“确定”，但我想在不单击“确定”按钮的情况下获取图像。我的代码如下，如果不单击确定按钮，我不知道如何获取图像，所以请帮助我。

button_camera.setOnClickListener(new OnClickListener() {

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

            Intent intent = new Intent("android.media.action.IMAGE_CAPTURE");
            startActivityForResult(intent, 0);
        }
    });



protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

    switch (requestCode) {
    case 0:
        if (resultCode == RESULT_OK) {


            Uri selectedImage = data.getData();
            String[] filePathColumn = { MediaStore.Images.Media.DATA };

            Cursor cursor = getContentResolver().query(selectedImage,
                    filePathColumn, null, null, null);
            cursor.moveToFirst();

            int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
            String filePath = cursor.getString(columnIndex);
            cursor.close();

            Log.e("PATH", filePath+"");
            Bitmap yourSelectedImage = BitmapFactory.decodeFile(filePath);

        }
    }

};

在按钮点击监听器上编写以下代码

 cameraBtn.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Intent intent = new Intent(MediaStore.INTENT_ACTION_STILL_IMAGE_CAMERA);
            startActivityForResult(intent, CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE);
        }
    });
