I realized according to the official API http://android.toolib.net/guide/topics/ui/settings.html a setting interface, click to enter the setup menu Activity feature not finished, is being given
menuWhich set the interface using the official recommended frangment form:

Activtiy setting interface:

public class settingActivity extends Activity {

@ Override
protected void onCreate (Bundle savedInstanceState) {
/ / TODO Auto-generated method stub
super.onCreate (savedInstanceState);
... getFragmentManager () beginTransaction () replace (android.R.id.content, new settingFragment ()) commit ();
}


}



Fragment settings interface:

public class settingFragment extends PreferenceFragment {

@ Override
public void onCreate (Bundle savedInstanceState) {
/ / TODO Auto-generated method stub
super.onCreate (savedInstanceState);
addPreferencesFromResource (R.xml.setting);
}

}



R.xml.setting:


android: key = "settings"
android: title = "Settings">
android: key = "basic"
android: title = "Basic Settings">
android: key = "text"
android: title = "text"
/>
android: key = "lightMode"
android: title = "night mode"
android: summaryOn = "Enabled"
android: summaryOff = "not enabled" />
android: key = "textSize"
android: title = "Text Size"
android: dialogTitle = "text size"

getFragmentManager () This method is only 3.0 in the future, and look at your development sdk version right, Manifest in setting the minimum version is not greater than 11.
If you want to look at the version 3.0 is compatible to devolve android-support-v4.jar this jar in the libs directory () instead of using getSupportFragmentManager getFragmentManager ().
