Setting的源代码是在AndroidManifest.xml中设置的

写在<application>标签里，如下：

<PreferenceScreen      
            android:title="@string/radio_controls_title"
            android:summary="@string/radio_controls_summary">
            <intent
                android:action="android.intent.action.MAIN"
                android:targetPackage="com.android.settings"
                android:targetClass="com.android.settings.WirelessSettings" />
        </PreferenceScreen>

然后在对应的Activity中写如下的java代码：

Intent wifiSettingsIntent = new Intent("android.settings.WIFI_SETTINGS"); 
   startActivity(wifiSettingsIntent);
