/**
|
* 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>
|
* <LinearLayout
|
xmlns:android="http://schemas.android.com/apk/res/android"
|
android:layout_width="match_parent"

|
* android:layout_height="wrap_content"
|
* android:layout_width="wrap_content"
|
* android:text="@string/hello" />
|
* </LinearLayout>
|
* </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);
