title: onTouchListener warning: onTouch should call View#performClick when a click is detected
body: <p>I have created a <code>onTouchListener</code>. Unfortunately onTouch() method <code>throws</code> me a warning:</p>
  <blockquote>
  <pre><code>com/calculator/activitys/Calculator$1#onTouch should call View#performClick when a click is detected
  </code></pre>
  </blockquote>
  <p>What does it mean? I have not found any information about this warn. Here is the full code:</p>
  <pre><code>LinearLayout llCalculatorContent = (LinearLayout) fragmentView.findViewById(R.id.calculator_content);
  
  llCalculatorContent.setOnTouchListener(new View.OnTouchListener() {
              
      @Override
      public boolean onTouch(View v, MotionEvent event) {
          Tools.hideKeyboard(getActivity(), getView());
          getView().clearFocus();
          return false;
      }   
  });
  </code></pre>
