[Android] onTouch in child보기가 응답하지 않습니다.

Question

셀을 터치 할 때마다 셀 값이 변경되는 스도쿠 격자를 만들려고 노력하고 있습니다. 그래서 Child View에 의해 LinearLayout에이 스도쿠 격자를 구현하고 OnTouch 메서드를 사용해 보았지만 작동하지 않습니다. onTouch가 실제로 호출되었는지 여부를 확인하기 위해 log 메소드를 사용했지만이 메소드가 완벽하게 무시 된 것 같습니다. 나는 다른 질문에 대한 해결책을 찾고 있었지만 그 해결책이 도움이되지 못하는 것 같습니다. 여기 좀 빠는 느낌이 들었습니다. 어떤 도움이라도 대단히 감사하겠습니다.

직접 단지 스도쿠 클래스의 객체를 생성하여 touchListener을 추가 할 수 없습니다. xml 또는 프로그램 방식으로보기를 추가해야합니다.

귀하의 활동

public class MyActivity extends Activity{ 
    @Override 
protected void onCreate(Bundle savedInstanceState){ 
super.onCreate(savedInstanceState); 

//initializing custom views 
MyCustomView1 myCustomView1 = new MyCustomView1(parameterList); 
MyCustomView2 myCustomView2 = new MyCustomView2(parameterList); 

//adding both custom views to the main activity 
mainView.addView(myCustomView1); 
mainView.addView(myCustomView1); 

//adding custom listener to the custom view 1 
myCustomView1.setCustomEventListener(new OnCustomEventListener() { 

    @Override 
    public void onEvent() { 
     //firing an event of custom view 1 
     Toast.makeText(MainActivity.this, "Touched custom view 1", 
       Toast.LENGTH_SHORT).show(); 
    } 
}); 

//adding custom listener to the custom view 2 
myCustomView2.setCustomEventListener(new OnCustomEventListener() { 

    @Override 
    public void onEvent() { 
     //firing an event of custom view 2 
     Toast.makeText(MainActivity.this, "Touched custom view 2", 
       Toast.LENGTH_SHORT).show(); 
    } 
}); 
} 
} 

귀하있는 CustomView 1

public class MyCustomView1 extends LinearLayout{ 
OnCustomEventListener myCustomEventListener; 

public MyCustomView1(ParameterList){ 
super(ContextFromParameterList); 
//Just adding something to the custom view 1 in order to distinguish it on the screen 
TextView tv = new TextView(ContextFromParameterList); 
tv.setText("Hello world from custom view 1"); 
addView(tv); 

this.setOnTouchListener(new OnTouchListener() { 

    @Override 
    public boolean onTouch(View v, MotionEvent event) { 
     //delegating one event to another (delegating touch event to custom event) 
     if (MyCustomView1.this.myCustomEventListener != null) 
      MyCustomView1.this.myCustomEventListener.onEvent(); 
     return false; 
    } 
}); } 

공공 무효 setCustomEventListener (OnCustomEventListener 의 EventListener) { // 활동에서 사용자 정의 리스너를 설정 myCustomEventListener =의 EventListener; }}

귀하의 CustomView2

public class MyCustomView2 extends LinearLayout { 
OnCustomEventListener myCustomEventListener; 

public MyCustomView2(ParameterList) { 
    super(ContextFromParameterList); 
//Just adding something to the custom view 1 in order to distinguish it on the screen 
TextView tv = new TextView(ContextFromParameterList); 
tv.setText("Hello world from custom view 2"); 
addView(tv); 

this.setOnTouchListener(new OnTouchListener() { 

    @Override 
    public boolean onTouch(View v, MotionEvent event) { 
     //delegating one event to another (delegating touch event to custom event) 
     if (MyCustomView2.this.myCustomEventListener != null) 
      MyCustomView2.this.myCustomEventListener.onEvent(); 
     return false; 
    } 
}); 
} 

    public void setCustomEventListener(OnCustomEventListener eventListener) { 
    //setting custom listener from activity 
    myCustomEventListener = eventListener; 
    } 
} 
Your listener interface: 

public interface OnCustomEventListener{ 
//interface defines one method. Can be more and methods may have parameters 
public void onEvent(); 
}
