Setting的原始碼是在AndroidManifest.xml中設定的

寫在<application>標籤裡，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>
 

然後在對應的Activity中寫如下的java程式碼：

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