Onclick和onTouch在android中无法正常工作

-1

我已经创建了一个在触摸监听器和onclick监听器上实现的活动。两者都没有在一起工作。如果ontouch的点击工作不起作用，并且onclick工作ontouch不起作用。这里是我的代码Onclick和onTouch在android中无法正常工作

public class QuickStart extends Activity implements OnTouchListener 
    { 
    private static final int SWIPE_MIN_DISTANCE = 120; 
    private static final int SWIPE_MAX_OFF_PATH = 250; 
    private static final int SWIPE_THRESHOLD_VELOCITY = 200; 
    private GestureDetector gestureDetector; 
    private ViewFlipper viewFlipper; 
    int page = 0; 
    private Button btn_menu; 
    private LinearLayout layout_menu; 
    Developer developer = new Developer(); 
    private ArrayList<SideMenuItem> arrayList = new ArrayList<SideMenuItem>(); 
    private SideMenuEntryAdapter adapter; 
    private ListView list_side; 
    private Context context; 
    private int flag = 0; 
     @Override 
     protected void onCreate(Bundle savedInstanceState) {   
     super.onCreate(savedInstanceState); 
     requestWindowFeature(Window.FEATURE_NO_TITLE); 
     setContentView(R.layout.quickstart); 
     context = this; 
     gestureDetector = new GestureDetector(new MyGestureDetector()); 
     setupUI(); 
     arrayList = developer.setupList(); 
     adapter = new SideMenuEntryAdapter(this, arrayList); 
     list_side.setAdapter(adapter); 
     list_side.setOnItemClickListener(new OnItemClickListener() { 
      @Override 
      public void onItemClick(AdapterView<?> arg0, View arg1, 
        int position, long arg3) { 
       System.out.println(position); 
       Developer.Menu(context, position,Developer.quick_start); 
       if (flag == 0) { 
        flag = 1; 
        layout_menu.setVisibility(LinearLayout.VISIBLE); 
       } else { 
        flag = 0; 
        layout_menu.setVisibility(LinearLayout.GONE); 
       } 
      } 
     }); 
    } 
    private void setupUI() { 
     viewFlipper = (ViewFlipper) findViewById(R.id.viewFlipper); 
     viewFlipper.setOnTouchListener(this); 
     btn_menu = (Button) findViewById(R.id.btn_menu); 
     layout_menu = (LinearLayout) findViewById(R.id.layout_menu); 
     list_side = (ListView) findViewById(R.id.listview_side); 
     btn_menu.setClickable(true); 
     layout_menu.setClickable(true); 
     list_side.setClickable(true); 
     btn_menu.setFocusable(true); 
     btn_menu.setFocusableInTouchMode(true); 
     layout_menu.setFocusable(true); 
     layout_menu.setFocusableInTouchMode(true); 
     list_side.setFocusable(true); 
     list_side.setFocusableInTouchMode(true); 
     btn_menu.setEnabled(true); 
     layout_menu.setEnabled(true); 
     list_side.setEnabled(true); 
     btn_menu.setOnClickListener(new Button.OnClickListener() { 
     @Override 
      public void onClick(View v) { 
       if (v == btn_menu) { 
        System.out.println("Menu"); 
        if (flag == 0) { 
        flag = 1; 
        layout_menu.setVisibility(LinearLayout.VISIBLE); 
        } else { 
         flag = 0; 
        layout_menu.setVisibility(LinearLayout.GONE); 
        } 
       } 
      } 
     }); 
    } 
    class MyGestureDetector extends SimpleOnGestureListener { 
     @Override 
     public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, 
       float velocityY) { 
      try { 

       if (Math.abs(e1.getY() - e2.getY()) > SWIPE_MAX_OFF_PATH) 
        return false; 
       if (e1.getX() - e2.getX() > SWIPE_MIN_DISTANCE 
         && Math.abs(velocityX) > SWIPE_THRESHOLD_VELOCITY) { 
        if (page < 7) { 
         page++; 
         viewFlipper.showNext(); 
        } 
       } else if (e2.getX() - e1.getX() > SWIPE_MIN_DISTANCE 
         && Math.abs(velocityX) > SWIPE_THRESHOLD_VELOCITY) { 

        if (page > 0) { 
         page--; 
        viewFlipper.showPrevious(); 
        } 
       } 
      } catch (Exception e) { 
       // nothing 
      } 
      return false; 
     } 

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

请格式化您的代码 – 2012-03-30 05:43:15

使您的活动实现onGestureListener。

然后在你的活动添加

private GestureDetector gestureScanner; 
gestureScanner = new GestureDetector(this); 
private static final int SWIPE_MIN_DISTANCE = 100; 
private static final int SWIPE_THRESHOLD_VELOCITY = 100;

然后overrid的的onTouchEvent（MotionEvent事件），如下图所示：

@Override  
public boolean onTouchEvent(MotionEvent event) { 
     return gestureScanner.onTouchEvent(event);  
}

而且最后，您需要在此改变onFling方法是这样的：

@Override  
public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, float velocityY) { 
     /* on scroll to the next page */   
if (e2.getX() - e1.getX() > SWIPE_MIN_DISTANCE && Math.abs(velocityX) > SWIPE_THRESHOLD_VELOCITY   ) { 
      //Ur code goes here   }   
/* on scroll to the previous page */ 
else if (e1.getX() - e2.getX() > SWIPE_MIN_DISTANCE && Math.abs(velocityX) > SWIPE_THRESHOLD_VELOCITY    ) {   
    //ur code goes here.   

}   return false;  }

你听得到它之前注册该侦听setOnTouchListener和setOnClickListener。

public boolean onTouch(View v, MotionEvent event) 
{ 
    int Action=event.getAction(); 
    switch(Action) 
    { 
    case MotionEvent.ACTION_DOWN: Log.d(tag , "down"); break; 
    case MotionEvent.ACTION_MOVE: Log.d(tag , "move"); break; 
    case MotionEvent.ACTION_UP: Log.d(tag , "up"); break; 
    } 

    return true; 
}

尝试此代码进行运动事件。我希望这会有所帮助。
