+/**
+ * A user interface element that displays text to the user.
+ * To provide user-editable text, see {@link EditText}.
+ * <p>
+ * The following code sample shows a typical use, with an XML layout
+ * and code to modify the contents of the text view:
+ * </p>
+
+ * <pre>
+ * &lt;LinearLayout
+       xmlns:android="http://schemas.android.com/apk/res/android"
+       android:layout_width="match_parent"
+       android:layout_height="match_parent"&gt;
+ *    &lt;TextView
+ *        android:id="@+id/text_view_id"
+ *        android:layout_height="wrap_content"
+ *        android:layout_width="wrap_content"
+ *        android:text="@string/hello" /&gt;
+ * &lt;/LinearLayout&gt;
+ * </pre>
+ * <p>
+ * This code sample demonstrates how to modify the contents of the text view
+ * defined in the previous XML layout:
+ * </p>
+ * <pre>
+ * public class MainActivity extends Activity {
+ *
+ *    protected void onCreate(Bundle savedInstanceState) {
+ *         super.onCreate(savedInstanceState);
+ *         setContentView(R.layout.activity_main);
+ *         final TextView helloTextView = (TextView) findViewById(R.id.text_view_id);
+ *         helloTextView.setText(R.string.user_greeting);
+ *     }
+ * }
+ * </pre>
+ * <p>
