如何设置OnTouchListener为整个画面？ [英] How to set OnTouchListener for the entire screen?

问题描述

请看看下面的code。我只张贴的code中的重要部分。

Please have a look at the following code. I am ONLY posting the important sections of the code.

activity_game.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/fullView"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context=".Game" >

    <TextView
        android:id="@+id/numberOfQuestionsLeft"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentLeft="true"
        android:layout_alignParentTop="true"
        android:layout_marginLeft="20dp"
        android:text="TextView" />
</RelativeLayout>

Game.java

public class Game extends Activity {



    private View fullView;

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_game);

        fullView = (View)findViewById(R.id.fullView);
        fullView.setOnTouchListener(imageViewSwiped);



    }


 OnTouchListener imageViewSwiped = new OnSwipeTouchListener()
    {
         public boolean onSwipeRight() 
         {
            //code removed
         }

          public boolean onSwipeLeft() 
          {
             //code removed
                return true;
          }

          public boolean onSwipeBottom()
          {
              //code removed
              return true;
          }


    };
}

OnSwipTouchListener.java

请注意 - 我并不拥有这个类的code。它写的是另一个的会员。

Note - I do not own this class of the code. It is written by another SO member.

  package game.Game;
    import android.view.GestureDetector;
    import android.view.GestureDetector.SimpleOnGestureListener;
    import android.view.MotionEvent;
    import android.view.View;
    import android.view.View.OnTouchListener;

    public class OnSwipeTouchListener implements OnTouchListener {

        private final GestureDetector gestureDetector = new GestureDetector(new GestureListener());

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

        private final class GestureListener extends SimpleOnGestureListener {

            private static final int SWIPE_THRESHOLD = 100;
            private static final int SWIPE_VELOCITY_THRESHOLD = 100;

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

            @Override
            public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, float velocityY) {
                boolean result = false;
                try {
                    float diffY = e2.getY() - e1.getY();
                    float diffX = e2.getX() - e1.getX();
                    if (Math.abs(diffX) > Math.abs(diffY)) {
                        if (Math.abs(diffX) > SWIPE_THRESHOLD && Math.abs(velocityX) > SWIPE_VELOCITY_THRESHOLD) {
                            if (diffX > 0) {
                                result = onSwipeRight();
                            } else {
                                result = onSwipeLeft();
                            }
                        }
                    } else {
                        if (Math.abs(diffY) > SWIPE_THRESHOLD && Math.abs(velocityY) > SWIPE_VELOCITY_THRESHOLD) {
                            if (diffY > 0) {
                                result = onSwipeBottom();
                            } else {
                                result = onSwipeTop();
                            }
                        }
                    }
                } catch (Exception exception) {
                    exception.printStackTrace();
                }
                return result;
            }
        }

        public boolean onSwipeRight() {
            return false;
        }

        public boolean onSwipeLeft() {
            return false;
        }

        public boolean onSwipeTop() {
            return false;
        }

        public boolean onSwipeBottom() {
            return false;
        }
    }

现在，我想使整个活动感动启用厂名。请查看 Game.java 来看看我是如何做的。但问题是，它不反应的任何种类的触摸事件的！没有什么错与code OnSwipTouchListener.java ，因为我已经由听众设置到图像视图中使用这种触摸事件。必须有一个问题，我想使使整个活动的触摸。说整个活动触已启用我的意思是，我需要在整个屏​​幕上滑动，而不是增加听众的的ImageView 。

Now, I am trying to make the make the WHOLE ACTIVITY touched enabled. Please view Game.java to see how I did it. But the problem is, it is not reacting to any kind of touch event! There is nothing wrong with the code OnSwipTouchListener.java because I have used the touch events of this by setting the listener to an image view. There must be a problem where I am trying to make the whole activity touch enabled. By saying "Whole Activity Touch Enabled" what I mean is, I need to swipe across the whole screen instead of adding the listener to an imageview.

我做了什么错在这里？请帮帮忙！

What have I done wrong here? Please help!
