触摸空白区域隐藏软键盘

2020-03-31

首先用了 这个第三方工具库： api 'com.blankj:utilcode:1.13.11'

然后在Activity页面里：

    @Override
    public boolean dispatchTouchEvent(MotionEvent ev) {
        if (ev.getAction() == MotionEvent.ACTION_DOWN) {
            View v = getCurrentFocus();
            if (isShouldHideKeyboard(v, ev)) {
                KeyboardUtils.hideSoftInput(this);
                if (KeyboardUtils.isSoftInputVisible(SearchActivity.this)) {
                    return true;
                }
            }
        }
        return super.dispatchTouchEvent(ev);
    }

    // Return whether touch the view.
    private boolean isShouldHideKeyboard(View v, MotionEvent event) {
        if ((v instanceof EditText)) {
            int[] l = {0, 0};
            v.getLocationOnScreen(l);
            int left = l[0], top = l[1], bottom = top + v.getHeight(), right = left + v.getWidth();
            return !(event.getRawX() > left && event.getRawX() < right && event.getRawY() > top && event.getRawY() < bottom);
        }
        return false;
    }
