微调器 OnTouchListener

Question

我正在尝试在spinner 上设置OnTouchListner。可以在自定义视图上调用它，但不能在微调器上调用。

还尝试使用MotionEvent.ACTION_DOWN。代码不适用于 Spinner 但 在 CustomView 上工作-

view.setOnTouchListener(new View.OnTouchListener() {

                @Override
                public boolean onTouch(View v, MotionEvent event) {
                    if(event.getAction()==MotionEvent.ACTION_DOWN){
                    pos=finalI;
                    Log.e("In View CLicked", "Clicked " + finalI);
                    loadVisitData();
                }

                return false;
            }
        }); 

代码在 Spinner 上不起作用-

spinDist.setOnTouchListener(new View.OnTouchListener() {
            @Override
            public boolean onTouch(View v, MotionEvent event) {
                if(event.getAction()==MotionEvent.ACTION_DOWN) {
                Log.e("Touch","OnTouch");
                }
                Toast.makeText ( EnquiryForm.this, "test", Toast.LENGTH_SHORT ).show();
                Log.e("Touch","OnTouch");
                return false;
            }
        });

通过覆盖 setOnTouchListener() 方法尝试对 Spinner 进行此操作，

spinDist.setOnTouchListener(new View.OnTouchListener() {
            @Override
            public boolean onTouch(View v, MotionEvent event) {
                if(event.getAction()==MotionEvent.ACTION_UP){
                    Toast.makeText ( EnquiryForm.this, "test", Toast.LENGTH_SHORT ).show();
              }
              return false;
          }
   });
