从Android相机捕获屏幕取消返回主页

Question

我遇到了从相机拍摄照片的问题。在我按下＆＃34;取消＆＃34;或＆＃34;确认＆＃34;按钮，它将返回主页而不是启动相机的活动。这是我的代码：

Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);                            
startActivityForResult(intent, TAKE_PICTURE_REQUEST);

我的代码可能有什么问题？感谢

修改1：

这是按钮点击监听器的代码：

DialogInterface.OnClickListener m_dialogOnclick = new DialogInterface.OnClickListener(){

    @Override
    public void onClick(DialogInterface dialog, int which) {

        switch (which) {
            case 0:
                Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);                            
                startActivityForResult(intent, TAKE_PICTURE_REQUEST);
                break;

            case 1:
                break;
            case 2:
                break;
            case 3:
                break;
        }
    }
};

您是否添加了onActivityResult方法？

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (requestCode == TAKE_PICTURE_REQUEST) {
        // Make sure the request was successful
        if (resultCode == RESULT_OK) {
            // Do something
        } else if (resultCode == RESULT_CANCELED) {
            // Do something else
        }
    }
}
