I am working on an android app which interacts with Twitter using their search API.
Everythings works well except that when I want to show the result using a ListView, only the first result is shown.
ArrayList<TwitterJSONResults> arrayList = new ArrayList<TwitterJSONResults>(data.getResults().size());
for (int i = 0; i < data.getResults().size(); i++) {
arrayList.add(data.getResults().get(i));
}
ArrayAdapter<TwitterJSONResults> resultAdapter = new ArrayAdapter<TwitterJSONResults>(
this, android.R.layout.simple_list_item_1, arrayList);
listview.setAdapter(resultAdapter);
resultAdapter.notifyDataSetChanged();
The code snippet above show how I add the results to the adapter and set this adapter to the the listview, What am I doing wrong?
Don’t put ListView inside of a ScrollView 🙂
Answer：
You can use ListView in ScrollView.
public class Utility {
public static void setListViewHeightBasedOnChildren(ListView listView) {
ListAdapter listAdapter = listView.getAdapter();
if (listAdapter == null) {
// pre-condition
return;
}
int totalHeight = 0;
int desiredWidth = MeasureSpec.makeMeasureSpec(listView.getWidth(), MeasureSpec.AT_MOST);
for (int i = 0; i < listAdapter.getCount(); i++) {
View listItem = listAdapter.getView(i, null, listView);
listItem.measure(desiredWidth, MeasureSpec.UNSPECIFIED);
totalHeight += listItem.getMeasuredHeight();
}
ViewGroup.LayoutParams params = listView.getLayoutParams();
params.height = totalHeight + (listView.getDividerHeight() * (listAdapter.getCount() - 1));
listView.setLayoutParams(params);
listView.requestLayout();
}
}
Call this function right after you change ListView items, like that:
Utility.setListViewHeightBasedOnChildren(myListView);

Thanks to @207 I realized that the problem in my case was because I was using NestedScrollView, so for me the solution was used
android:fillViewport="true"
Here my code:
<android.support.v4.widget.NestedScrollView
android:id="@+id/content_frame"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fillViewport="true"
app:layout_behavior="@string/appbar_scrolling_view_behavior">
</android.support.v4.widget.NestedScrollView>
Answer：
I have had this error like you when put listview inside ScrollView. And my solution is following as:
1. Create a custom listview which is non scrollable
public class NonScrollListView extends ListView {
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();
}
}
2. Use above custom class for xml file
<xx.xx.NonScrollListView
android:id="@+id/lv_nonscroll_list"
android:layout_width="match_parent"
android:layout_height="wrap_content" >
</xx.xx.NonScrollListView>
It worked well on all OS-version for me.
Hope best for you.
Answer：
It turns out I had everything in my java code working perfectly. the issue was that was using the listview inside a scrollview which is generally a bad idea. It led to listview ignoring
android:layout="wrap_content"
therefore the content was there, it just was not showing. After I remove the scrollview from my XML file, everything worked file.
Big thanks to 207 for the support 🙂
Answer：
You can use a ListView inside a NestedScrollView.
The only thing you have to remember is to add android:nestedScrollingEnabled="true" in the xml layout in order to enable the scroll of NestedScrollView’s children.
Answer：
Put it in ListView xml layout
android:stackFromBottom="true"
android:transcriptMode="alwaysScroll"
Answer：
this is my answere
<android.support.v4.widget.NestedScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fillViewport="true"
app:layout_behavior="@string/appbar_scrolling_view_behavior">
<ListView
android:minWidth="25px"
android:minHeight="25px"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="@string/appbar_scrolling_view_behavior"
android:id="@+id/listViewRefeCalendarDay" />
</android.support.v4.widget.NestedScrollView>
