如何让搜索查看松动重点和活动的其他地方点击后崩溃 [英] how to make searchview loose focus and collapse when clicked elsewhere on activity

问题描述

在我的应用程序，我做其中搜索查看折叠和展开时，搜索界面失去和获得焦点分别。然而，在失去重心的东西只能通过两种方法实现：

In my app, i'm making a search interface in which the SearchView collapses and expands when looses and gains focus respectively. However, the loosing focus thing is only done by 2 methods:

1）。如果pressed后退按钮。

1). If back button is pressed.

2）。如果除了搜索查看主页图标点击。

2). If home icon besides the searchview is clicked.

我希望它失去焦点（因此崩溃），如果用户点击，不仅对这两件事情，但其他地方在屏幕上。它可以是任何东西，即。一个按钮或屏幕上的部分，而不在其上的任何图。我的意思是在空白屏幕上。

I want it to loose focus (and hence collapse) if the user clicks not only on these two things, but anywhere else on the screen. It can be anything viz. a button or the portion on the screen without any view on it. I mean on a blank screen.

推荐答案

嗯，我发现了以下解决方案。我用setOnTouchListener上的每个观点，不是搜索查看的一个实例崩溃的搜索查看。它的工作适合我。以下是code。

Well I found out the following solution. I used setOnTouchListener on every view that is not an instance of searchview to collapse the searchview. It worked perfect for me. Following is the code.

public void setupUI(View view) {

    if(!(view instanceof SearchView)) {

        view.setOnTouchListener(new OnTouchListener() {

            public boolean onTouch(View v, MotionEvent event) {
                searchMenuItem.collapseActionView();
                return false;
            }

        });
    }

    //If a layout container, iterate over children and seed recursion.
    if (view instanceof ViewGroup) {

        for (int i = 0; i < ((ViewGroup) view).getChildCount(); i++) {

            View innerView = ((ViewGroup) view).getChildAt(i);

            setupUI(innerView);
        }
    }
}

这是我提到的答案。
