我能知道如何在ActionBar中添加Switch小部件并处理click事件或切换更改事件.

Can I know how to add Switch widget in ActionBar and handle the click event or toggle change event.

目前，我可以在ActionBar中为Switch充气，但无法响应更改事件.我已经在下面添加到main.xml中.

For now I can inflate the Switch in ActionBar but unable to respond to change event. I have added below to main.xml.

<menu xmlns:android="schemas.android/apk/res/android" xmlns:tools="schemas.android/tools" tools:context="com.example.MainActivity" > <item android:id="@+id/toggleservice" android:actionViewClass="android.widget.Switch" android:showAsAction="ifRoom" android:title="@string/toggle_service"/> </menu>

我想在用户单击开关并更改其状态时启动服务.任何帮助都将受到高度赞赏.

I want to start a service when user clicks on switch and change it's state. Any help is highly appreciated.

推荐答案

您需要致电 MenuItem.getActionView ，这是一个示例:

You need to call MenuItem.getActionView, here's an example:

@Override public boolean onCreateOptionsMenu(Menu menu) { // Inflate your Menu getMenuInflater().inflate(R.menu.your_menu, menu); // Get the action view used in your toggleservice item final MenuItem toggleservice = menu.findItem(R.id.toggleservice); final Switch actionView = (Switch) toggleservice.getActionView(); actionView.setOnCheckedChangeListener(new OnCheckedChangeListener() { @Override public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) { // Start or stop your Service } }); return super.onCreateOptionsMenu(menu); }
