In android, A ListView Contains a TextView, and how to set minHeight for TextView - android-listview

Question

I have a ListItem with TextView.I set the minHeight of TextView as follows.
list_item_forecast.xml
<TextView ?xml version="1.0" encoding="utf-8"?>
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id = "#+id/list_item_forecast_textView"
android:gravity="center_vertical"
android:minHeight="?android:attr/listPreferredItemHeight"
/>
and the fragment file xml is as follows.
fragment_main.xml
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
android:paddingBottom="#dimen/activity_vertical_margin"
tools:context=".ForecastFragment">
<ListView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/listView_forecast"
/>
Even though I set the minHeight of textView to "?android:attr/listPreferredItemHeight" , I am seeing the output on device as follows.
This the code in fragment.java. Need to display forecastArrayAdapter String data in ListView
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_main, container, false);
String[] forecastArray = new String[]{"Today - Sunny - 86/83",
"Tomorrow - Foggy - 70/46",
"Weds - Cloudy - 72/63",
"Thurs - Rainy - 64/51",
"Fri - Foggy - 70/46",
"Sat - Sunny - 76/68",
"Sun - Sunny - 20/7"};
List<String> weekForecast = new ArrayList<String>(Arrays.asList(forecastArray));
ArrayAdapter<String> mForecastAdapter = new ArrayAdapter<String>(getActivity(), R.layout.list_item_forecast,
R.id.list_item_forecast_textView,weekForecast );
ListView listView = (ListView) rootView.findViewById(R.id.listView_forecast);
listView.setAdapter(mForecastAdapter);
return rootView;
}
Could someone help me out setting the minHeight for each text?
Thanks

Though I can't see any TextView in your list_item_forcast.xml
In your text view you have to add: android:minLines = "3" and android:maxLines = "3"
It will keep the height of textView for 3 lines.
A sample TextView will look like:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:padding="6dip" >
<TextView
android:id="#+id/tv_addesc"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:scrollbars="vertical"
android:maxLines="3"
android:minLines="3"
android:textColor="#FFFFFFFF"
android:textSize="15sp" />
</RelativeLayout>
Note: If the number of characters exceeds the 3 line limit then it will show text like below:
"
Hello world
Hello world
Hello world..."
