SearchView 的 OnCloseListener 不起作用

问题描述

我正在尝试在 Android 3.0+ ActionBar 中添加对 SearchView 的支持，但我无法让 OnCloseListener 工作.

I'm trying to add support for the SearchView in the Android 3.0+ ActionBar, but I can't get the OnCloseListener to work.

这是我的代码:

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.menu, menu);
    searchView = (SearchView) menu.findItem(R.id.search_textbox).getActionView();
    searchView.setOnQueryTextListener(new OnQueryTextListener() {
        @Override
        public boolean onQueryTextChange(String newText) {
            searchLibrary(newText);
            return false;
        }
        @Override
        public boolean onQueryTextSubmit(String query) { return false; }
    });
    searchView.setOnCloseListener(new OnCloseListener() {
        @Override
        public boolean onClose() {
            System.out.println("Testing. 1, 2, 3...");
            return false;
        }
    });
    return true;
}

搜索效果很好，除了 OnCloseListener 之外，每个都可以正常工作.Logcat 没有打印任何内容.这是我按下关闭"按钮时的 Logcat:

The search works great and every is working except for the OnCloseListener. Nothing is being printed to Logcat. Here's the Logcat for when I'm pressing the "Close" button:

02-17 13:01:52.914: I/TextType(446): TextType = 0x0
02-17 13:01:57.344: I/TextType(446): TextType = 0x0
02-17 13:02:02.944: I/TextType(446): TextType = 0x0

我已经浏览了文档和示例，但似乎没有任何变化它.我在 Asus Transformer Prime 和 Galaxy Nexus 上运行它，两者都在 Ice Cream Sandwich 上.有什么想法吗?

I've looked through the documentation and samples, but nothing seemed to change it. I'm running it on a Asus Transformer Prime and a Galaxy Nexus, both on Ice Cream Sandwich. Any ideas?

更新:

是的 - System.out.println() 确实有效.证据如下:

Yes - System.out.println() does work. Here's proof:

   @Override
 public boolean onQueryTextChange(String newText) {
    System.out.println(newText + "hello");
    searchLibrary(newText);
    return false;
 }

此 Logcat 中的结果:

Results in this Logcat:

02-17 13:04:20.094: I/System.out(21152): hello
02-17 13:04:24.914: I/System.out(21152): thello
02-17 13:04:25.394: I/System.out(21152): tehello
02-17 13:04:25.784: I/System.out(21152): teshello
02-17 13:04:26.064: I/System.out(21152): testhello

推荐答案

我也遇到这个问题，只好放弃oncloselistener".相反，您可以获取您的 menuItem，然后是 setOnActionExpandListener.然后覆盖未实现的方法.

I also meet this problem, and I have no choice but give up "oncloselistener". Instead, you can get your menuItem, then setOnActionExpandListener. Then override unimplents methods.

@Override
public boolean onMenuItemActionExpand(MenuItem item) {
    // TODO Auto-generated method stub
    Log.d("*******","onMenuItemActionExpand");
    return true;
}

@Override
public boolean onMenuItemActionCollapse(MenuItem item) {
    //do what you want to when close the sesarchview
    //remember to return true;
    Log.d("*******","onMenuItemActionCollapse");
    return true;
}
