我实现双击时遇到问题.好吧,我实现了onGestureListener,我有gestureDetector,但我不知道问题出在哪里,这是我的代码:
public class home extends TabActivity implements OnGestureListener {
/** Called when the activity is first created. */
private EditText queryText;
private ResultsAdapter m_adapter;
private ProgressDialog pd;
final Handler h = new Handler();
private TabHost mTabHost;
private ArrayList<SearchItem> sResultsArr = new ArrayList<SearchItem>();
private String queryStr;
private JSONObject searchResponse;
private GestureDetector gestureScanner;
final Runnable mUpdateResults = new Runnable() {
public void run() {
updateListUi();
}
};
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Button search = …我想检测一个doubletap视图,例如a button,然后知道它是哪个视图.我已经看到了这个类似的问题,但他们说这是一个重复的问题似乎没有回答我的问题.
所有我能找到是一个添加GestureDetector到活动中,并添加OnDoubleTapListener到它.但只有在我点击屏幕的背景/布局时才会触发.当我(双击)a时,它不会被触发button.
这是我里面的代码onCreate:
gd = new GestureDetector(this, this);
gd.setOnDoubleTapListener(new OnDoubleTapListener()
{
@Override
public boolean onDoubleTap(MotionEvent e)
{
Log.d("OnDoubleTapListener", "onDoubleTap");
return false;
}
@Override
public boolean onDoubleTapEvent(MotionEvent e)
{
Log.d("OnDoubleTapListener", "onDoubleTapEvent");
//if the second tap hadn't been released and it's being moved
if(e.getAction() == MotionEvent.ACTION_MOVE)
{
}
else if(e.getAction() == MotionEvent.ACTION_UP)//user released the screen
{
}
return false;
}
@Override
public boolean onSingleTapConfirmed(MotionEvent …
