I am confused about this strange problem. Normally, on many phones, this is not a problem. But I tried three MIUI10 phones with this problem, and other systems have not encountered it. Perhaps this is a MIUI10 system bug?
If you have a MIUI10 phone, please help test it.
And how can I solve this problem to be compatible with many devices? All help is welcome.
The code is as follows, very simple:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView
android:id="@+id/text"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_alignParentBottom="true"
android:layout_marginBottom="50dp"
android:padding="15dp"
android:background="#1ad9ca"
android:textColor="#ffffff"
android:text="Hold to talk" />
</RelativeLayout>
findViewById(R.id.text).setOnTouchListener(new View.OnTouchListener() {
@Override
public boolean onTouch(View view, MotionEvent motionEvent) {
switch (motionEvent.getAction()) {
case MotionEvent.ACTION_DOWN:
Log.d(TAG, "ACTION_DOWN");
break;
case MotionEvent.ACTION_MOVE:
Log.d(TAG, "ACTION_MOVE");
break;
case MotionEvent.ACTION_UP:
Log.d(TAG, "ACTION_UP");
break;
case MotionEvent.ACTION_CANCEL:
Log.d(TAG, "ACTION_CANCEL");
break;
}
return true;
}
});
And in my device, Hold TextView for a few seconds and raise my hand , ACTION_CANCEL is called, and ACTION_UP is not called . Here are the logs:
D/MainActivity: ACTION_DOWN
D/MainActivity: ACTION_MOVE
D/MainActivity: ACTION_MOVE
D/MainActivity: ACTION_CANCEL
And I want to do some logic in ACTION_UP case , not in ACTION_CANCEL case.
The test device info:
Phone name: Xiaomi 8
Android system version: Android 9
MIUI system version: MIUI 10.1.2.0
Verified on my miui phone, this problem occurs only on 10.2.xx version, when upgrading to 10.3.3.0, the problem no more occurs.
While dispatching ACTION_UP event, miui intercepts this event and changes action from ACTION_UP to ACTION_CANCEL, but nothing popup shows on screen, seems like a bug on 10.2.xx
