我正在尝试在 MainActivity 中绑定服务，绑定服务由updateTheNotification()在 MainActivity 中定义的方法中创建的意图绑定，如下所示：
public void updateTheNotification()
{
Intent intentz = new Intent(context.getApplicationContext(), NotificationService.class);
context.getApplicationContext().bindService(intentz, mConnection, Context.BIND_ABOVE_CLIENT);
if (mBound) {
// Call a method from the LocalService.
// However, if this call were something that might hang, then this request should
// occur in a separate thread to avoid slowing down the activity performance.
mService.changeTheUI(true);
Toast.makeText(this, "Service triggered", Toast.LENGTH_LONG).show();
}
}
/** Defines callbacks for service binding, passed to bindService() */
private ServiceConnection mConnection = new ServiceConnection() {
@Override
public void onServiceConnected(ComponentName className,
IBinder service) {
// We've bound to LocalService, cast the IBinder and get LocalService instance
NotificationService.LocalBinder binder = (NotificationService.LocalBinder) service;
mService = binder.getService();
mBound = true;
}
@Override
public void onServiceDisconnected(ComponentName arg0) {
mBound = false;
}
};
updateTheNotification() 由广播接收器 onReceive 方法调用，该方法附加到通知上的按钮。
