I am developing an application and would like to have the user
navigate the app using gestures. I tried using the GestureDetector but
some of the gestures are not detected. I am trying to allow them to go
backwrds and forward by doing a left-to-right and right-to-left
gestures. I tried to detect the onFling and onScroll and I got
nothing, any help would be greatly appreciated.
Here is my code, just in case:
public class MyActivity extends Activity implements OnTouchListener,
OnGestureListener{
GestureDetector mGestureDetector;
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
mGestureDetector = new GestureDetector(this);
mGestureDetector.setIsLongpressEnabled(false);
setContentView(R.layout.article);
TextView tv = (TextView)findViewById(R.id.page);
tv.setOnTouchListener(this);
tv.setText(R.string.article_text);
}
public boolean onTouch(View v, MotionEvent event) {
// TODO Auto-generated method stub
return mGestureDetector.onTouchEvent(event);
}
public boolean onDown(MotionEvent e) {
// TODO Auto-generated method stub
return false;
}
public boolean onFling(MotionEvent e1, MotionEvent e2, float
velocityX,
float velocityY) {
// TODO Auto-generated method stub
Toast.makeText(this, "Fling", Toast.LENGTH_SHORT).show();
return false;
}
public void onLongPress(MotionEvent e) {
// TODO Auto-generated method stub
//Toast.makeText(this, "Long Press", Toast.LENGTH_SHORT).show();
}
public boolean onScroll(MotionEvent e1, MotionEvent e2, float
distanceX,
float distanceY) {
// TODO Auto-generated method stub
Toast.makeText(this, "Scroll", Toast.LENGTH_SHORT).show();
return false;
}
public void onShowPress(MotionEvent e) {
// TODO Auto-generated method stub
}
public boolean onSingleTapUp(MotionEvent arg0) {
// TODO Auto-generated method stub
return false;
}
}
