这是一个截图(我已经输入了文字,你可以看到它没有显示)：

我已经尝试使用this SO question改变了SearchView上的文本颜色,并且我也尝试在可搜索的配置XML文件中更改文本颜色.当我发现这些都没有工作,我解除了我的更改,以便您可以看到我当前有如下代码：

MainActivity.java

@Override
public boolean onCreateOptionsMenu(Menu) { 

    ...

    // Associate searchable configuration with the SearchView
    SearchManager searchManager = (SearchManager) getSystemService(SEARCH_SERVICE);
    MenuItem searchMenuItem = menu.findItem(R.id.action_search);
    SearchView searchView = (SearchView) searchMenuItem.getActionView();
    searchView.setSearchableInfo(searchManager.getSearchableInfo(new ComponentName(this,SearchResultsActivity.class)));
    // Note: getSearchableInfo(getComponentName()) will not work on all flavours
    // because of a difference in app IDs

}

请注意,我使用新的ComponentName(…)而不是getSearchableInfo(getComponentName()),因为我使用不同的口味不同的包名称.

上述活动是显示SearchView的地方.结果显示在另一个活动中.

searchable.xml

<searchable xmlns:android="http://schemas.android.com/apk/res/android"
    android:label="@string/app_name"
    android:hint="@string/search_hint" />

            android:name="android.app.default_searchable"

    </activity>

    ...

有什么想法可能会发生什么或应该如何解决？
