Android 点击editview以外位置实现隐藏输入法

@Override   public boolean dispatchTouchEvent(MotionEvent ev) {     if (ev.getAction() == MotionEvent.ACTION_DOWN) {       View v = getActivity().getCurrentFocus();       if (isShouldHideInput(v, ev)) {          InputMethodManager imm = (InputMethodManager) getActivity().getSystemService(Context.INPUT_METHOD_SERVICE);         if (imm != null) {           imm.hideSoftInputFromWindow(v.getWindowToken(), 0);         }       }       return getActivity().dispatchTouchEvent(ev);     }     // 必不可少，否则所有的组件都不会有TouchEvent了     if (getActivity().getWindow().superDispatchTouchEvent(ev)) {       return true;     }     return getActivity().onTouchEvent(ev);   }    public boolean isShouldHideInput(View v, MotionEvent event) {     if (v != null && (v instanceof EditText)) {       int[] leftTop = { 0, 0 };       //获取输入框当前的location位置       v.getLocationInWindow(leftTop);       int left = leftTop[0];       int top = leftTop[1];       int bottom = top + v.getHeight();       int right = left + v.getWidth();       if (event.getX() > left && event.getX() < right           && event.getY() > top && event.getY() < bottom) {         // 点击的是输入框区域，保留点击EditText的事件         return false;       } else {         return true;       }     }     return false;   }
