私はアンドロイドアプリを作っています。ユーザーがaをチェックすると常にバックグラウンドで実行されるサービスを作成しています。ユーザーがチェックするcheckbox
と停止する必要がunckeck
あります。したがって、ボックスをチェックすると機能し、「サービス開始」トーストも表示されますがuncheck
、checkbox
「サービスが停止しました」というトーストが表示されますが、サービスが開始されたときに開始された音の再生は停止しません。その音を止める唯一の方法は、携帯電話の電源を切ってから入れることです。
サービスを開始および停止するための私のJavaコードは次のとおりです
public int onStartCommand(Intent intent, int flags, int startId) {
Toast.makeText(this, "Service Started", Toast.LENGTH_LONG).show();
this.registerReceiver(this.batteryInfoReceiver, new IntentFilter(Intent.ACTION_BATTERY_CHANGED));
return START_STICKY;
}
public void onDestroy() {
super.onDestroy();
Toast.makeText(this, "Service Stopped", Toast.LENGTH_LONG).show();
}
ここに私のxmlファイルがあります
<CheckBoxPreference
android:title="Enable/Disable Alarm"
android:defaultValue="true"
android:key="cbAlarm"
android:summary="Enable or disable alarm" />
ここに私のlogcatがあります
