I am writing an Android app that uses an AutoCompleteTextView just like the API example. The problem is that my text is too long and needs to wrap when the dropdown occurs. I have a custom list_item.xml, but only one line of text displays. The list_item.xml layout wraps to 2 lines if used with a spinner, but not with the AutoCompleteTextView.
main.java
public class main extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
AutoCompleteTextView textView = (AutoCompleteTextView) findViewById(R.id.autocomplete_country);
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, R.layout.list_item, COUNTRIES);
textView.setAdapter(adapter);
}
static final String[] COUNTRIES = new String[] {
"This is the first line that is too long and it needs to wrap content",
"Albania", "Algeria", "American Samoa", "Andorra",
"This is a second line that also needs to wrap its content",
"Bahrain", "Bangladesh", "Barbados", "Belarus", "Belgium"
};
}
main.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:padding="5dp">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Country" />
<AutoCompleteTextView android:id="@+id/autocomplete_country"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginLeft="5dp"/>
</LinearLayout>
list_item.xml
<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:padding="10dp"
android:textSize="16sp"
android:textColor="#000"
>
</TextView>
Wrap the TextView in a layout and use that for your ArrayAdapter
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<TextView
android:id="@+id/item"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:padding="10dp"
android:textSize="16sp"
android:textColor="#000"
/>
</LinearLayout>
And the new calls for the ArrayAdapter
:
AutoCompleteTextView textView = (AutoCompleteTextView) findViewById(R.id.autocomplete_country);
ArrayAdapter<String> adapter = new ArrayAdapter<String>(getActivity(), R.layout.list_item, R.id.item, COUNTRIES);
textView.setAdapter(adapter);
easy way :
adapter = new ArrayAdapter(getApplicationContext(), android.R.layout.two_line_list_item,android.R.id.text1,....);
android.R.layout.two_line_list_item this is easy change.
