list view on relative layout didn't show - android-listview

Question

activity_sms.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
>
<ListView
android:id="#+id/SMSList"
android:layout_height="match_parent"
android:layout_width="match_parent"
android:layout_margin="10dp"
/>
</RelativeLayout>
code on SMSActivity.java
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_sms);
smsListView = (ListView) findViewById(R.id.SMSList);
arrayAdapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, smsMessagesList);
smsListView.setAdapter(arrayAdapter);
smsListView.setOnItemClickListener(this);
code on fragment_1.java
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.activity_sms, container, false);
return rootView;
I tried to make a program to read SMS from inbox and show it on a ListView. It works when SMSActivity is the only activity there
Now, I use MainActivity.java instead of SMSActivity.java as Main Activity.
My goal is to invoke SMSActivity.java using fragment.
If anyone can help me it would be nice :)

What exactly you want to show in your layout?For example you have some items like this
<LinearLayout
android:layout_weight="1"
android:orientation="vertical"
android:paddingLeft="30dp"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<TextView
android:id="#+id/list_item_title"
android:text="#string/title"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<TextView
android:id="#+id/list_item_details"
android:text="#string/description"
android:paddingTop="10dp"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</LinearLayout>
In ths case you can set the value for this items in your adapter
#Override
public View getView (int position,View convertView,ViewGroup parent){
View view = LayoutInflater.from(context).inflate(R.layout.linear_big_list_item, parent, false);
TextView nameOfItem = (TextView)convertView.findViewById(R.id.list_item_title);
TextView descriptionOfItem = (TextView)convertView.findViewById(R.id.list_item_details);
return view;
}
