Я хочу, чтобы иметь возможность дважды нажмите где-нибудь в ImageView и это то сделать что-то

Мой код для двойного крана следующего

detector = new GestureDetector(context, new GestureDetector.SimpleOnGestureListener() { 
     @Override 

      public boolean onDoubleTapEvent(MotionEvent ev) { 
      int x = (int)ev.getX(); 
      int y = (int)ev.getY(); 

      SubsamplingScaleImageView imageView = (SubsamplingScaleImageView)findViewById(R.id.imageView); 
      PointF sCoord = imageView.viewToSourceCoord(ev.getX(), ev.getY()); 
      if(sCoord.x > 1940 && sCoord.x < 2119 && sCoord.y > 1558 && sCoord.y < 1719){Demovar.roomname="141"; }; 
      if(sCoord.x > 2120 && sCoord.x < 2322 && sCoord.y > 1558 && sCoord.y < 1719){Demovar.roomname="142";}; 
      if(sCoord.x > 2323 && sCoord.x < 2520 && sCoord.y > 1558 && sCoord.y < 1719){Demovar.roomname="143";}; 
      return true; 
      }

Я наклоняю для жизни мне работать, где я могу добавить код, чтобы сделать его работу я продолжаю получать ошибки

Пожалуйста, простите меня, если это очевидный вопрос, я действительно новые жесты

любой помощь

Марком ОБНОВЛЕНО КОД

    this.requestWindowFeature(Window.FEATURE_NO_TITLE); 
    this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,  WindowManager.LayoutParams.FLAG_FULLSCREEN);  
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.main); 
    mImage = (ImageView) findViewById(R.id.mImageView); 

    final GestureDetector gestureDetector = new GestureDetector(this, new GestureListener()); 
    mImage.setOnTouchListener(new OnTouchListener() { 

        public boolean onTouch(View v, MotionEvent event) { 
         return gestureDetector.onTouchEvent(event); 
        } 
       });

этот код дает ошибку ниже Mark

ли вы назначаете Читающий мысли к Teh ImageView ?? –

Вам необходимо зарегистрировать сенсорный прослушиватель, чтобы вызвать GestureDetector

GestureDetector gestureDetector = new GestureDetector(context, new GestureListener()); 
    imageView.setOnTouchListener(new OnTouchListener() { 

        @Override 
        public boolean onTouch(View v, MotionEvent event) { 
         return gestureDetector.onTouchEvent(event); 
        } 
       });

Итак, вы код будет выглядеть так:

public void onCreate(final Bundle savedInstanceState) { 
     this.requestWindowFeature(Window.FEATURE_NO_TITLE); 
     this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, 
       WindowManager.LayoutParams.FLAG_FULLSCREEN); 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 
     mImage = (ImageView) findViewById(R.id.mImageView); 

     final GestureDetector gestureDetector = new GestureDetector(this, 
       new GestureListener()); 
     mImage.setOnTouchListener(new OnTouchListener() { 

      public boolean onTouch(View v, MotionEvent event) { 
       return gestureDetector.onTouchEvent(event); 
      } 
     }); 
    } 

    private class GestureListener extends 
      GestureDetector.SimpleOnGestureListener { 

     @Override 
     public boolean onDown(MotionEvent e) { 
      return true; 
     } 

     // event when double tap occurs 
     @Override 
     public boolean onDoubleTap(MotionEvent e) { 
      float x = e.getX(); 
      float y = e.getY(); 

      Log.d("Double Tap", "Tapped at: (" + x + "," + y + ")"); 

      return true; 
     } 
    }

Спасибо за это. Любая идея, в которую я вставляю ее в основную деятельность. Когда я ставлю ее, я получаю ошибки – user3422687
