Android TimePicker (Wheel Style) not responding correctly to flick gestures inside ScrollView
I had the same problem when using the Holo theme, and here is where I found the solution: https://groups.google.com/forum/?fromgroups#!topic/android-developers/FkSfJI6dH8w
You must implement your custom DatePicker or TimePicker and override the following method:
@Override
public boolean onInterceptTouchEvent(MotionEvent ev)
{
if (ev.getActionMasked() == MotionEvent.ACTION_DOWN)
{
ViewParent p = getParent();
if (p != null)
p.requestDisallowInterceptTouchEvent(true);
}
return false;
}
Because the link from Klemens Zleptnig is broken, here is a complete example. This fix helps with the scroll of a TabLayout too btw. I excluded the area around the big numbers in the top of the TimePicker because they don't need the scroll event anyway.
xml:
<com.name.app.MyTimePicker
android:id="@+id/timePicker"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
.../>
java:
public class MyTimePicker extends TimePicker {
public MyTimePicker(Context context) {
super(context);
}
//This is the important constructor
public MyTimePicker(Context context, AttributeSet attrs) {
super(context, attrs);
}
public MyTimePicker(Context context, AttributeSet attrs, int defStyleAttr) {
super(context, attrs, defStyleAttr);
}
public MyTimePicker(Context context, AttributeSet attrs, int defStyleAttr, int defStyleRes) {
super(context, attrs, defStyleAttr, defStyleRes);
}
@Override
public boolean onInterceptTouchEvent(MotionEvent ev)
{
if (ev.getActionMasked() == MotionEvent.ACTION_DOWN) {
//Excluding the top of the view
if(ev.getY() < getHeight()/3.3F)
return false;
ViewParent p = getParent();
if (p != null)
p.requestDisallowInterceptTouchEvent(true);
}
return false;
}
}
