如何检测android应用程序的电源按钮事件

<receiver android:name=".PowerButtonReceiver">
    <intent-filter>
        <action android:name="android.intent.action.ACTION_SCREEN_OFF" />
        <action android:name="android.intent.action.ACTION_SCREEN_ON" />
        <action android:name="android.intent.action.ACTION_USER_PRESENT" />
    </intent-filter>
</receiver>

public class PowerButtonReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        if (intent.getAction().equals(Intent.ACTION_SCREEN_OFF)) {
            // 处理屏幕关闭事件
        } else if (intent.getAction().equals(Intent.ACTION_SCREEN_ON)) {
            // 处理屏幕打开事件
        } else if (intent.getAction().equals(Intent.ACTION_USER_PRESENT)) {
            // 处理用户解锁事件
        }
    }
}

PowerButtonReceiver receiver = new PowerButtonReceiver();
IntentFilter filter = new IntentFilter();
filter.addAction(Intent.ACTION_SCREEN_OFF);
filter.addAction(Intent.ACTION_SCREEN_ON);
filter.addAction(Intent.ACTION_USER_PRESENT);
registerReceiver(receiver, filter);
