<activity android:name=".Hello_World"
android:label="This is the Hello World Application">
</activity>
Java:
public class TitleBar extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
final boolean customTitleSupported = requestWindowFeature(Window.FEATURE_CUSTOM_TITLE);
setContentView(R.layout.main);
if ( customTitleSupported ) {
getWindow().setFeatureInt(Window.FEATURE_CUSTOM_TITLE, R.layout.titlebar);
}
final TextView myTitleText = (TextView) findViewById(R.id.myTitle);
if ( myTitleText != null ) {
myTitleText.setText("NEW TITLE");
// user can also set color using "Color" and then "Color value constant"
// myTitleText.setBackgroundColor(Color.GREEN);
}
}
}
我得到non-static method setTitle(CharSequence) cannot be referenced from a static context错误,因为我在静态PlaceholderFragment类中使用了setTitle()。我通过使用getActivity().getActionBar().setTitle("new title");来解决它
