How can we simulate long press by touch event? or how can we calculate the time that screen is touched, all in ACTION_DOWN state?
I have implemented a Touch screen long click finally , thx all:
textView.setOnTouchListener(new View.OnTouchListener() {
private static final int MIN_CLICK_DURATION = 1000;
private long startClickTime;
@Override
public boolean onTouch(View v, MotionEvent event) {
switch (event.getAction()) {
case MotionEvent.ACTION_UP:
longClickActive = false;
break;
case MotionEvent.ACTION_DOWN:
if (longClickActive == false) {
longClickActive = true;
startClickTime = Calendar.getInstance().getTimeInMillis();
}
break;
case MotionEvent.ACTION_MOVE:
if (longClickActive == true) {
long clickDuration = Calendar.getInstance().getTimeInMillis() - startClickTime;
if (clickDuration >= MIN_CLICK_DURATION) {
Toast.makeText(MainActivity.this, "LONG PRESSED!",Toast.LENGTH_SHORT).show();
longClickActive = false;
}
}
break;
}
return true;
}
});
in which private boolean longClickActive = false;
is a class variable.
