Question

<string name="read_more_1">first messages.</string> 
<string name="read_more_2">second messages.</string> 
<string name="read_more_3">third messages.</string> 

simple activity:

 public class dynamic_Activity extends Activity {
       @Override
       public void onCreate(Bundle savedInstanceState) {
           super.onCreate(savedInstanceState);

           setContentView(R.layout.dynamic_layout_01);

          txtDisplay = (TextView) findViewById(R.id.textView1);  

          //getting position value from the previous activity
          int position = getIntent().getIntExtra("position", default_value); 

          if (position > 0)
          {  
          String _format = "read_more_" + String.valueOf(position);
          txtDisplay.setText(R.string._format); // how to assign the string id?

          } else {
          txtDisplay.setText(R.string.read_more_0); //by default
          }  
       }
    }

layout file:

<LinearLayout
        android:id="@+id/linearLayout1"
        android:layout_width="match_parent"
        android:layout_height="fill_parent"
        android:orientation="vertical" >

        <TextView
            android:id="@+id/textView1"
            android:layout_width="fill_parent"
            android:layout_height="fill_parent"
            android:text="@string/dynamic_0" 
            android:textSize="12dp" />
    </LinearLayout>

In this particular case, I think you should look into using a string array resource.
