的onClick阻塞onFling [英] onClick blocking onFling

问题描述

在我的活动我有一个ImageView的（顶部）和TextView的（底部）。使用这两种观点我显示图像和其相应的描述。我一直在使用'SimpleOnGestureListener'..，这样用户可以通过不同的图像和其相应的描述一扔（每次一扔，我加载不同的图像，并将其展示给用户）来实现一扔。

In my activity I have an imageView(at the top) and textView(at the bottom). Using both views I display an image and its corresponding description. I have implemented fling using 'SimpleOnGestureListener'..so that user can fling through different images and its corresponding description(on every fling, I load different image and show it to user).

现在的问题开始时，我加入onClickListener的ImageView的（我需要检测的onClick，这样我可以显示图像的描述敬酒）。但onClick的似乎是阻塞一扔事件。如何检测一扔。

Now the problem started when I added onClickListener for the ImageView( I need to detect onClick so that I can display a Toast with description of the image). But the onClick seems to be blocking the fling event. How do I detect fling.

通过本论坛下面的问题（和其他几个）已走了。

Have already gone through the following questions(and few others) in this forum..

但还是没能找出解决办法。

but still could not identify the solution.

下面给出的是code

Given below is the code

public class MainActivity extends Activity{
    ImageView m_imageView;
    String[] m_imageNames = { "img1__", "img2__", "img2__"};
    int m_index = 0;
    Resources m_res;
    Drawable m_drawable;

    @Override
    public void onCreate(Bundle savedInstanceState) {
       super.onCreate(savedInstanceState);
       setContentView(R.layout.activity_main);
       Log.v("INFO", "Inside oncreate");

       m_imageView = (ImageView)findViewById(R.id.imageView1);
       m_res = getResources();
       int imageId = m_res.getIdentifier(m_imageNames[m_index], "drawable", getPackageName());
       Drawable drawable = m_res.getDrawable(imageId);
       m_imageView.setImageDrawable(drawable);

       m_imageView.setOnClickListener(new View.OnClickListener() {

       @Override
       public void onClick(View v) {
          Log.v("INFO", "Inside onClick");
       }
       });
  }

  @Override
  public boolean onTouchEvent(MotionEvent event) {
     Log.v("INFO", "onTouchEvent detected");
     return gestureDetector.onTouchEvent(event);
  }

  SimpleOnGestureListener simpleOnGestureListener
   = new SimpleOnGestureListener(){

    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;

    @Override
    public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, 
        float velocityY) {
                //Fling code goes here
        }
   };

   GestureDetector gestureDetector = new GestureDetector(null, SimpleOnGestureListener);

}

推荐答案

这些方法一般有布尔回报，这表明，该事件已经被消耗掉，不应继续传播。尝试改变返回值。

These methods generally have boolean returns, which indicate that this event has been consumed and should not propagate further. Try changing return values.
