Android 点击EditText区外隐藏键盘

一、重写 dispatchTouchEvent，在每次 ACTION_DOWN 事件中动态判断非 EditText 区域的点击事件

    @Override
    public boolean dispatchTouchEvent(MotionEvent ev) {
        if (ev.getAction() == MotionEvent.ACTION_DOWN) {
            View v = getCurrentFocus();
            if (isShouldHideInput(v, ev)) {
                InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
                if (imm != null) {
                    imm.hideSoftInputFromWindow(v.getWindowToken(), 0);
                }
            }
            return super.dispatchTouchEvent(ev);
        }
        return getWindow().superDispatchTouchEvent(ev) || onTouchEvent(ev);
    }

    public boolean isShouldHideInput(View v, MotionEvent event) {
        if (v != null && (v instanceof EditText)) {
            int[] leftTop = {0, 0};
            v.getLocationInWindow(leftTop);
            int left = leftTop[0];
            int top = leftTop[1];
            int bottom = top + v.getHeight();
            int right = left + v.getWidth();
            return !(event.getX() > left) || !(event.getX() < right)
                    || !(event.getY() > top) || !(event.getY() < bottom);
        }
        return false;
    }

二、在父布局的点击事件做处理

   InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
   if (imm != null) {
       imm.hideSoftInputFromWindow(v.getWindowToken(), 0);
   }
