i have a listview and implemented onclick and also onfling.problem is when i do fling(swipe left to right), onclick event of listview is also getting executed.How to overCome this problem? how to differentiate touch(tap) and fling(swipe) in listview?
listClickListener = new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View v,int position, long id) {
//Job of Onclick Listener
}
};
mContactList.setOnItemClickListener(listClickListener);
mContactList.setAdapter(adapter);
// Gesture detection
gestureDetector = new GestureDetector(new MyGestureDetector(prosNos));
gestureListener = new View.OnTouchListener() {
public boolean onTouch(View v, MotionEvent event) {
if (gestureDetector.onTouchEvent(event)) {
return true;
}
return false;
}
};
mContactList.setOnTouchListener(gestureListener);
}
public class MyGestureDetector extends SimpleOnGestureListener {
@Override
public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, float velocityY) {
// My fling event
return false;
}
}
P.S. Is it possible? to comment the OnClickListener of ListView and writing the same logic in any onTouchEvent? but still I have no doubt that onFling will call onTouch. Am I right?
Pseudo code answer to clarify the above comments. How to have the MySimpleGestureListener's onTouch method called.
public class GestureExample extends Activity {
protected MyGestureListener myGestureListener;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
myGestureListener = new MyGestureListener(this);
// or if you have already created a Gesture Detector.
// myGestureListener = new MyGestureListener(this, getExistingGestureDetector());
// Example of setting listener. The onTouchEvent will now be called on your listener
((ListView)findViewById(R.id.ListView)).setOnTouchListener(myGestureListener);
}
@Override
public boolean onTouchEvent(MotionEvent event) {
// or implement in activity or component. When your not assigning to a child component.
return myGestureListener.getDetector().onTouchEvent(event);
}
class MyGestureListener extends SimpleOnGestureListener implements OnTouchListener
{
Context context;
GestureDetector gDetector;
public MyGestureListener()
{
super();
}
public MyGestureListener(Context context) {
this(context, null);
}
public MyGestureListener(Context context, GestureDetector gDetector) {
if(gDetector == null)
gDetector = new GestureDetector(context, this);
this.context = context;
this.gDetector = gDetector;
}
@Override
public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, float velocityY) {
return super.onFling(e1, e2, velocityX, velocityY);
}
@Override
public boolean onSingleTapConfirmed(MotionEvent e) {
return super.onSingleTapConfirmed(e);
}
public boolean onTouch(View v, MotionEvent event) {
// Within the MyGestureListener class you can now manage the event.getAction() codes.
// Note that we are now calling the gesture Detectors onTouchEvent. And given we've set this class as the GestureDetectors listener
// the onFling, onSingleTap etc methods will be executed.
return gDetector.onTouchEvent(event);
}
public GestureDetector getDetector()
{
return gDetector;
}
}
}
