UnsupportedOperationException: addView(View, LayoutParams) is not supported in AdapterView
I am trying to create a simple Android app and I'm getting this error:
java.lang.RuntimeException: Unable to start activity ComponentInfo{com.twista.shopinglist/com.twista.shopinglist.ItemDetail}: java.lang.UnsupportedOperationException: addView(View, LayoutParams) is not supported in AdapterView
I tried to google it and fix via some answers here, but unsuccessfuly it didn't resolve :(.
I have a MainActivity with ListView, in onCreate() I call
public class MainActivity extends Activity {
....
@Override
protected void onCreate(Bundle savedInstanceState) {
...
final ListView listView = (ListView) findViewById(R.id.overListView);
List<Item> values = dataSource.getItems();
final ArrayAdapter<Item> adapter = new ArrayAdapter<Item>(this,
android.R.layout.simple_list_item_1, values);
listView.setAdapter(adapter);
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
Item i = adapter.getItem(position);
Intent intent = new Intent(MainActivity.this, ItemDetail.class);
Bundle bundle = new Bundle();
bundle.putLong("my_id", i.getId());
intent.putExtras(bundle);
startActivity(intent);
}
});
this code should start new activity, ItemDetail, whose code is here:
public class ItemDetail extends Activity {
private ItemsDataSource dataSource;
private long itemId;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.detail);
Bundle bundle = getIntent().getExtras();
itemId = bundle.getLong("my_id");
Intent intent = getIntent();
dataSource = new ItemsDataSource(this);
try {
dataSource.open();
} catch (SQLException e) {
e.printStackTrace();
}
ListView listView = (ListView) findViewById(R.id.detailListView);
List<SubItem> values = dataSource.getSubItemOfItem(itemId);
ArrayAdapter<SubItem> adapter = new ArrayAdapter<SubItem>(this,
android.R.layout.simple_list_item_1, values);
listView.setAdapter(adapter);
i'm still get this error:

Many thanks for any advice.
Answer
Your XML file contains Views that are children of a ListView, you cannot do this. Your XML file should look liks this:
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<ListView
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1.0"
android:id="@+id/detailListView" />
<LinearLayout
android:id="@+id/groupSub"
android:layout_width="match_parent"
android:layout_height="wrap_content" >
<Button
android:id="@+id/add_sub"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Add New"
android:onClick="onClick"/>
<Button
android:id="@+id/delete_sub"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Delete First"
android:onClick="onClick"/>
</LinearLayout>
</LinearLayout>
