WearOS onGenericMotionListener未调用

Question

当我在三星Galaxy Watch 4上旋转我的眼罩时，我正试图捕捉它的动作，但它从来没有“运行”过。

这是我的代码：

findViewById(R.id.Badtunna).setOnGenericMotionListener(new View.OnGenericMotionListener() {
        @Override
        public boolean onGenericMotion(View view, MotionEvent motionEvent) {
            System.out.println("GUM");
            if(motionEvent.getAction() == MotionEvent.ACTION_SCROLL &&
            motionEvent.isFromSource(InputDeviceCompat.SOURCE_ROTARY_ENCODER)) {
                System.out.println("BUBBEL");

                return true;
            }
            return false;
        }
    });

我的观点是一个普通的TextView：

<TextView
            android:id="@+id/Badtunna"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="Badtunna" />

这是我的onCreate()在MainActivity中

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    binding = ActivityMainBinding.inflate(getLayoutInflater());
    setContentView(binding.getRoot());

    StrictMode.ThreadPolicy policy = new
    StrictMode.ThreadPolicy.Builder().permitAll().build();
    StrictMode.setThreadPolicy(policy);

    // Add all the domoticz devices
    domoticz_devices.put(766, "idx_766");
    domoticz_devices.put(17, "idx_17");

    findViewById(R.id.Skymningssensor).requestFocus();

    findViewById(R.id.Skymningssensor).setOnGenericMotionListener(new View.OnGenericMotionListener() {
        @Override
        public boolean onGenericMotion(View view, MotionEvent motionEvent) {
            System.out.println("GUM");
            if(motionEvent.getAction() == MotionEvent.ACTION_SCROLL &&
                    motionEvent.isFromSource(InputDeviceCompat.SOURCE_ROTARY_ENCODER)) {
                System.out.println("BUBBEL");

                return true;
            }
            return false;
        }
    });

    TextView idx_17_button = findViewById(R.id.idx_17);
    idx_17_button.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            try {
                toggleDomoticzDevice(17, "idx_17");
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    });

    TextView idx_657_button = findViewById(R.id.idx_657);
    idx_657_button.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            try {
                toggleDomoticzDevice(657, "idx_657");
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    });


    handler.postDelayed(new Runnable() {
        @Override
        public void run() {
            for (Integer i : domoticz_devices.keySet()) {
                getDomoticzDeviceAndSetTextview(i, domoticz_devices.get(i));
            }
            handler.postDelayed(this, delay);
        }
    }, delay);
}

当焦点在“工作”时，键盘应该弹出吗？我还更新了我的TextView并添加了可聚焦的:true和focusableintouchmode:true

提前感谢！

可能的问题是焦点

记住要确保您的视图获得焦点，否则事件就不会发生。

默认情况下，启动一个活动甚至点击一个视图都不会给它带来焦点，即使它是可聚焦的。为了提供视图焦点，视图必须使用标记或手动调用View.requestFocus().
