找不到类的android.support.v7.widget.SearchView $ 5' [英] Could not find class 'android.support.v7.widget.SearchView$5'

问题描述

我得到y中logcat中此错误。 没有人知道它是什么？

  08-22 19：02：57.830：E / dalvikvm（660）：找不到类的android.support.v7.widget.SearchView $ 5'，从法的Andr​​oid引用。 support.v7.widget.SearchView.addOnLayoutChangeListenerToDropDownAnchorSDK11
 

解决方案

没有很多code熄灭了这里，但我遇到了这个情况我自己，这里就是发生在我身上：

我用的是V7 COMPAT库，以便有一个动作条在Android 2 我实现了搜索界面的东西。

基本设置code（在 onCreateOptionsMenu（））

  SearchManager searchManager =
        （SearchManager）getActivity（）getSystemService（Context.SEARCH_SERVICE）。
SupportMenuItem searchMenuItem =（（SupportMenuItem）menu.findItem（R.id.menu_search））;
搜索查看搜索查看=（搜索查看）searchMenuItem.getActionView（）;
sea​​rchView.setSearchableInfo（searchManager.getSearchableInfo（activity.getComponentName（）））;
 

为code

  searchMenuItem.setOnActionExpandListener（新MenuItem.OnActionExpandListener（）{
    @覆盖
    公共布尔onMenuItemActionExpand（菜单项项）{
        //在搜索扩展的东西
        返回true;
    }

    @覆盖
    公共布尔onMenuItemActionCollapse（菜单项项）{
        //对搜索崩溃的东西
        返回true;
    }
}）;
 

不幸的是这里的问题是，我们调用了仅支持V14这样我们就得到一个怪异的运行时错误时，它会尝试加载一些类，隐式使用的方法。这不是一个很好的解释，但基本上这是我们需要使用同样的道理 getSupportActionBar（）而不是 getActionBar（）。

好code

  searchMenuItem.setSupportOnActionExpandListener（新MenuItemCompat.OnActionExpandListener（）{
    @覆盖
    公共布尔onMenuItemActionExpand（菜单项项）{
        // 做工作
        返回true;
    }

    @覆盖
    公共布尔onMenuItemActionCollapse（菜单项项）{
        // 做工作
        返回true;
    }
}）;
 

I get this error in y Logcat. Does anyone know what it is?

    08-22 19:02:57.830: E/dalvikvm(660): Could not find class 'android.support.v7.widget.SearchView$5', referenced from method android.support.v7.widget.SearchView.addOnLayoutChangeListenerToDropDownAnchorSDK11

解决方案

There isn't a lot of code to go off of here, but I ran into this situation myself and here is what happened to me:

I was using the v7 compat library in order to have an ActionBar on Android 2 I am implementing the search interface stuff.

Basic Setup Code (in onCreateOptionsMenu())

SearchManager searchManager =
        (SearchManager) getActivity().getSystemService(Context.SEARCH_SERVICE);
SupportMenuItem searchMenuItem = ((SupportMenuItem) menu.findItem(R.id.menu_search));
SearchView searchView = (SearchView) searchMenuItem.getActionView();
searchView.setSearchableInfo(searchManager.getSearchableInfo(activity.getComponentName()));

Bad Code

searchMenuItem.setOnActionExpandListener(new MenuItem.OnActionExpandListener() {
    @Override
    public boolean onMenuItemActionExpand(MenuItem item) {
        // on search expand stuff
        return true;
    }

    @Override
    public boolean onMenuItemActionCollapse(MenuItem item) {
        // on search collapse stuff
        return true;
    }
});

Unfortunately the problem here is that we are calling a method that is only supported in v14 so we get a "weird" run-time error when it tries to load some classes that are implicitly used. That's not a very good explanation, but basically it's the same reason we need to use getSupportActionBar() instead of getActionBar().

Good Code

searchMenuItem.setSupportOnActionExpandListener(new MenuItemCompat.OnActionExpandListener() {
    @Override
    public boolean onMenuItemActionExpand(MenuItem item) {
        // do work
        return true;
    }

    @Override
    public boolean onMenuItemActionCollapse(MenuItem item) {
        // do work
        return true;
    }
});
