在Android中未触发onActivityResult

我正在制作一个android应用程序，它从相机上获取图像，然后显示出来。但是，我无法显示单击的图像，可能是因为未触发onActivityResult（）

这是我的一段代码。有人能告诉我我错过了什么吗

public class Main extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        final int CAMERA_PIC_REQUEST = 1337; 
        Button b = (Button) findViewById(R.id.button1);
        b.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE); 
                startActivityForResult(cameraIntent, CAMERA_PIC_REQUEST);

            }
            @override
            public void onActivityResult(int requestCode, int resultCode, Intent data) {
                Log.d("Message1", "I reached 2");
                 //super.onActivityResult(requestCode, resultCode, data);
                if (requestCode == CAMERA_PIC_REQUEST) {
                    // do something
                    Bitmap thumbnail = (Bitmap) data.getExtras().get("data");  
                    ImageView image = (ImageView) findViewById(R.id.imageView1);  
                    image.setImageBitmap(thumbnail); 

                }
            }




        });
    }
} 

onActivityResult（）必须在活动类中声明（而不是在onClickListener中）。如果您更正当前onActivityResult（）声明之前的“@override”（'o'必须大写），键入错误，您将明白我的意思

看

下面是您的班级应该是什么样子：

public class Main extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        final int CAMERA_PIC_REQUEST = 1337; 
        Button b = (Button) findViewById(R.id.button1);
        b.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE); 
                startActivityForResult(cameraIntent, CAMERA_PIC_REQUEST);

            }
        });
    }


    @Override
    public void onActivityResult(int requestCode, int resultCode, Intent data) {
       Log.d("Message1", "I reached 2");
       //super.onActivityResult(requestCode, resultCode, data);
       if (requestCode == CAMERA_PIC_REQUEST) {
         // do something
         Bitmap thumbnail = (Bitmap) data.getExtras().get("data");  
         ImageView image = (ImageView) findViewById(R.id.imageView1);  
         image.setImageBitmap(thumbnail); 
       }
     }

}

我应该删除@Override并将onActivityResult（）放在Activity类之外吗？\@Override注释告诉编译器您要声明的函数应该覆盖父类中的某些内容。目前，您键入\@Override的方式有误——o没有大写！因此，编译器不会警告您覆盖无效。您应该将onActivityResult声明为直接位于活动类内部。我更新了我的答案…我是否应该删除@Override并将onActivityResult（）放在Activity类之外？\@Override注释告诉编译器您声明的函数应该覆盖父类中的某些内容。目前，您键入\@Override的方式有误——o没有大写！因此，编译器不会警告您覆盖无效。您应该将onActivityResult声明为直接位于活动类内部。我更新了我的答案。。。
