Android,点击空白处收起系统键盘(EditText)

直接上代码,有用的话,求惠存:

 @Override
    public boolean dispatchTouchEvent(MotionEvent ev) {
        if (ev.getAction() == MotionEvent.ACTION_DOWN) {
            View view = getCurrentFocus();
            if (isHideInput(view, ev)) {
                HideSoftInput(view.getWindowToken());
                view.clearFocus();
            }
        }
        return super.dispatchTouchEvent(ev);
    }
    /**
     * 判定是否需要隐藏
     */
    private boolean isHideInput(View v, MotionEvent ev) {
        if (v != null && (v instanceof EditText)) {
            int[] l = {0, 0};
            v.getLocationInWindow(l);
            int left = l[0], top = l[1], bottom = top + v.getHeight(), right = left + v.getWidth();
            if (ev.getX() > left && ev.getX() < right && ev.getY() > top && ev.getY() < bottom) {
                return false;
            } else {
                return true;
            }
        }
        return false;
    }
    /**
     * 隐藏软键盘
     */
    private void HideSoftInput(IBinder token) {
        if (token != null) {
            InputMethodManager manager = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
            manager.hideSoftInputFromWindow(token, InputMethodManager.HIDE_NOT_ALWAYS);
        }
    }

直接粘在Avtivity后就可以啦!(本人项目中,“登录”界面可用)
