Android: ScrollView does not scroll

I am trying to create a layout with a title, a banner under it, and then a couple of ListView under the banner. I want the whole screen to be scrollable except for the title. Now I know that the ListView does not scroll in the ScrollView, so I set the height of the ListView large enough to show all the elements. The problem is that even after these changes, I see that the ListView scrolls independently, and the full screen does not scroll.

<include android:id="@+id/logo_header" android:layout_width="fill_parent" android:layout_height="wrap_content" layout="@layout/screen_header" /> <ScrollView android:layout_width="match_parent"

Change the scroll view height from match_parent to wrap_content. Because the scroll view only allows scrolling if its overall height is greater than the height of the parent view. those. replace

 <ScrollView android:layout_width="match_parent" android:layout_height="match_parent" android:fillViewport="true">

using this code:

 <ScrollView android:layout_width="match_parent" android:layout_height="wrap_content" android:fillViewport="true">

I have used several methods several times in several applications. I use a special subclass of ListView:

 package com.yourcompany.appname.views; import android.content.Context; import android.util.AttributeSet; import android.view.ViewGroup; import android.widget.ListView; public class NonScrollableListView extends ListView { public NonScrollableListView(Context context) { super(context); } public NonScrollableListView(Context context, AttributeSet attrs) { super(context, attrs); } public NonScrollableListView(Context context, AttributeSet attrs, int defStyle) { super(context, attrs, defStyle); } @Override protected 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(); } }

Then in your layout, instead of using it's use something like this:

 <LinearLayout android:layout_width="match_parent" android:layout_height="wrap_content" android:orientation="vertical"> <com.yourcompany.appname.views.NonScrollableListView android:id="@+id/listId" android:layout_width="match_parent" android:layout_height="wrap_content" /> </LinearLayout>

Hope this helps!

You can try this,

  listView.setOnTouchListener(new OnTouchListener() { public boolean onTouch(View v, MotionEvent event) { if (event.getAction() == MotionEvent.ACTION_MOVE) { return true; } return false; } });

put the list list in another xml and include it as shown below

 <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent"> <include layout="@layout/show_message_header" /> <ScrollView android:id="@+id/myscrollview_Show_message" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_marginTop="@dimen/header" android:fadingEdge="none" android:fillViewport="false" android:paddingRight="0dp" android:scrollbarAlwaysDrawVerticalTrack="false" android:scrollbarSize="0dp" android:scrollbarStyle="insideOverlay" android:scrollbars="none" > <TableLayout android:id="@+id/Show_message_dynamic_table" android:layout_width="match_parent" android:layout_height="fill_parent" > <include layout="@layout/desinglayoutforlistviewincludehere" /> </TableLayout> </ScrollView>
