解开服务时遇到问题

我创建了一个自定义按钮的类。所以这个类扩展了Button类。

在这个类中，我将我的类与远程服务绑定以更新按钮状态。

    public class CustomButton extends Button implements View.OnClickListener {
    private Activity mActivity;

    public CustomButton(Context context) {
            super(context);
            init(context, null);
        }

    private void init(Context context, AttributeSet attrs) {
    if (context instanceof Activity) {
                this.mActivity =  (Activity) context;


    Intent intent = new Intent(mActivity, CustomService.class);

            final IRemoteCustomServiceCallback callback = new IRemoteCustomServiceCallback.Stub() {
                @Override
                public void stateChanged(boolean state) throws RemoteException {
                    Log.i("stateChanged", "New state is " + String.valueOf(state));
                    setAvailableMode(state);
                }

                @Override
                public IBinder asBinder() {
                    return this;
                }
            };

            ServiceConnection remoteConnection = new ServiceConnection() {
                @Override
                public void onServiceConnected(ComponentName name, IBinder service)
                {
                    mService = IRemoteCustomService.Stub.asInterface(service);

                    try {
                        int test = mService.getPid();
                        Log.i("test", String.valueOf(test));

                        mService.registerCallback(callback);
                    } catch (RemoteException e) {
                        e.printStackTrace();
                    }
                }

                @Override
                public void onServiceDisconnected(ComponentName name) {
                    try {
                        mService.unregisterCallback(callback);
                    } catch (RemoteException e) {
                        e.printStackTrace();
                    }
                    mService = null;
                }
            };
            boolean state = mActivity.bindService(intent, remoteConnection, 0);
}

问题是：当我关闭应用程序时，我收到一个错误：＆＃34; [...]已泄露最初绑定的ServiceConnection [...]＆＃34;

我理解这个错误，但因为我没有收到＆＃34;信号＆＃34; onStop或onDestroy，我无法取消绑定我的服务。

你知道我怎么解决它吗？

Answer 1

您必须覆盖方法

protected void onDetachedFromWindow() {
}

使用此方法取消注册/取消绑定远程服务

自定义按钮类中的unbindService
