under the settings ,it has alot of options for us to set, there are two ways to add some app into the setting perference.
1. write an app separating from the settings source code,it is an independent app .
Just the inputmethod can do like this.
2. change the settings source code.
Today we talk about this way.
*****************************************************************
First ,you should add the activity that you want to write into the AndroidManifest.xml
Like
<activity android:name="ExampleSettings" android:label="@string/example_settin
<intent-filter>
<action android:name="android.intent.action.MAIN" />
</intent-filter>
</activity>
also add the layout that pressing the perference that you add .
under the /res/layout/ ,and the add some item into strings.xml
************************************************************************
Second
add one perference into the exsit xml file
Like
<PreferenceScreen
android:key="button_example_key"
android:title="@string/example_settings"
android:summary="set and get the example number">
</PreferenceScreen>
add source java code under the exsit java file.
Like
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
init code>>>>>>>>>>>>>>>
private static final String BUTTON_EXAMPLE_KEY = "button_example_key";
private PreferenceScreen mButtonExampleKey;
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
detect code>>>>>>>>>>>>
else if(preference == mButtonExampleKey){
Intent intent_example = new Intent(this,ExampleSettings.class);
intent_example.setAction(Intent.ACTION_MAIN);
startActivity(intent_example);
return true;
}
mButtonExampleKey =(PreferenceScreen) prefSet.findPreference(BUTTON_EXAMPLE_KEY);
