我正在尝试用android触发警报,但它不起作用。我的代码没有给出Toast或“ALARMOFF”消息。我有这个BroadcastReceiver:
public class AlarmReceiver extends BroadcastReceiver {
public static void addAlarm(Context context){
Log.i("infodb","ADDEDALARM");
AlarmManager am = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
Intent intent = new Intent(context,AlarmReceiver.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(context,0,intent,0);
am.set(AlarmManager.RTC_WAKEUP, System.currentTimeMillis() + 5000, pendingIntent);
}
@Override
public void onReceive(Context context, Intent intent) {
PowerManager pm = (PowerManager) context.getSystemService(Context.POWER_SERVICE);
PowerManager.WakeLock wl = pm.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK, "");
wl.acquire();
Toast.makeText(context, "Alarm !!", Toast.LENGTH_SHORT).show(); // For example
Log.i("infodb","ALARMOFF");
wl.release();
}
}
在清单中,我有<receiver android:name=".AlarmReceiver" />
以及<uses-permission android:name="android.permission.WAKE_LOCK" />
在ListView中打开开关时会触发警报。这个代码在扩展的SimpleCursorAdapter类的bindView方法中:
@Override
public void bindView(View v, Context context, Cursor c) {
String name = c.getString(c.getColumnIndex("name"));
final long time = c.getLong(c.getColumnIndex("time"));
TextView time_text = (TextView) v.findViewById(R.id.time);
if (time_text != null) {
time_text.setText(date_format.format(new Date(time)));
}
TextView name_text = (TextView) v.findViewById(R.id.name);
if (name_text != null) {
name_text.setText(name);
}
// Do on/off button alarm code
Switch onOff = (Switch)v.findViewById(R.id.alarm_switch);
onOff.setChecked(c.getInt(c.getColumnIndex("onOff")) == 1);
final Context contextl = context;
final long id = c.getInt(c.getColumnIndex("_id"));
onOff.setOnCheckedChangeListener(new OnCheckedChangeListener(){
@Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
AlarmDatabase database = new AlarmDatabase(contextl);
SQLiteDatabase write = database.getWritableDatabase();
ContentValues values = new ContentValues(1);
if (isChecked){
// Alarm has been turned on
values.put("onOff",1);
// Add system alarm
AlarmReceiver.addAlarm(contextl);
}else{
// Alarm has been switched off
values.put("onOff",0);
// Remove system alarm
}
write.update(AlarmDatabase.ALARMS_TABLE, values, "_id = " + id, null);
write.close();
database.close();
}
});
}
当开关打开时,LogCat显示以下内容:
12-06 13:50:12.365: I/infodb(18968): ADDEDALARM

我在不同的地方寻找解决方案,但我只能确定我正在做的一切正确,但显然我不是。
感谢您的帮助。

如果你有不同的包,你应该正确使用包名
接收器android:name =“XXX.XXXXXXXXXXXXXXX.AlarmReceiver”/&gt;
