问题
I am using CoordinatorLayout in my activity page. In that there is ListView below the app bar. But its not working when I use ListView instead of NestedScrollView. And if I put ListView inside NestedScrollView, ListView is not expanding
回答1:
For the CoordinatorLayout to work properly you need the scrolling child to implement NestedScrollingChild. Such classes are NestedScrollView and RecyclerView.
To say it short - just use a RecyclerView for your scrolling content and it'll work correctly :)
P.S. As a side note, I don't see a reason why you'd use a ListView anymore. I know it's a habit and it's easier to setup (because you've done it many times), but using a RecyclerView is the recommended way anyways.
回答2:
you can fix it when you add addtribute android:fillViewport="true" in android.support.v4.widget.NestedScrollView :) . This my code.
<android.support.v4.widget.NestedScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:scrollbars="none"
app:layout_behavior="@string/appbar_scrolling_view_behavior"
android:fillViewport="true"
>
<ListView
android:id="@+id/list_myContent"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:scrollbars="vertical"
>
</ListView>
</android.support.v4.widget.NestedScrollView>
回答3:
on Lollipop onwards you can use
setNestedScrollingEnabled(true);
on your ListView/GridView/ScrollableView. From the documentation
Enable or disable nested scrolling for this view
if you need backwards compatibility with older version of the OS you'll have to use the RecyclerView. You can read more here
Edit.
ViewCompat has the static method setNestedScrollingEnabled(View, boolean). Eg.
ViewCompat.setNestedScrollingEnabled(listView, true)
thanks to @Dogcat for pointing it out
回答4:
Just put android:fillViewport="true" inside you NestedScrollView Tag
回答5:
this is what worked for me.
set android:fillViewport="true" on the NestedScrollView
add One Layout Element as Child to NestedScrollView. In my case LinearLayout and then
set android:nestedScrollingEnabled="true" on ListView
Make ListView a child of LinearLayout
Good to go

You listview will scroll. Hope help.

回答7:
Below code worked for me:
ViewCompat.setNestedScrollingEnabled(listView, true);
Your ListView should be inside NestedScrollView
回答8:
Replace your ListView with RecyclerView if possible else create your customListView and set onMeasure of ListView to this:
public NonScrollListView(Context context) {
super(context);
}
public NonScrollListView(Context context, AttributeSet attrs) {
super(context, attrs);
}
public NonScrollListView(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
}
@Override
public void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
int heightMeasureSpec_custom = MeasureSpec.makeMeasureSpec(
Integer.MAX_VALUE >> 2, MeasureSpec.AT_MOST);
super.onMeasure(widthMeasureSpec, heightMeasureSpec_custom);
ViewGroup.LayoutParams params = getLayoutParams();
params.height = getMeasuredHeight();
}
This ListView won't be able to scroll anymore and can be used inside NestedScrollView.

You can't scroll listview inside a nestedscrollview.Use Recyclerview with nestedscrollview

回答10:
Just add android:nestedScrollingEnabled="true" tag inside your NestedScrollView.
<android.support.v4.widget.NestedScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:scrollbars="none"
android:nestedScrollingEnabled="true">
<ListView
android:id="@+id/list_myContent"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:scrollbars="vertical">
</ListView>

I found that this solution by Prokash Sarkar worked perfectly for expanding the content of a ListView so that it can properly scroll inside a NestedScrollView.
Can't scroll ListView in its parent NestedScrollView - Android
Hope this helps others who search for NestedScrollView and ListView..
