【问题描述】：
我已经安装了支持库以使操作栏在 android pre API 11 中也能正常工作
当我启动应用程序时，logcat 给出这个错误：
08-20 19:54:41.600: I/dalvikvm(9828): Failed resolving Landroid/support/v7/widget/SearchView$5; interface 809 'Landroid/view/View$OnLayoutChangeListener;'

谁能帮帮我，我在网上搜索，但我一无所获。 谢谢
MainActivity.Java

}
@Override

MenuItem searchItem = menu.findItem(R.id.action_search);
SearchManager searchManager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);
SearchView searchView = (SearchView) MenuItemCompat.getActionView(searchItem);
// Configure the search info and add any event listeners
searchView.setSearchableInfo(searchManager.getSearchableInfo(getComponentName()));
searchView.setIconifiedByDefault(true);
return super.onCreateOptionsMenu(menu);
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {

return true;
default:
return false;
}
}
}
【问题讨论】：
-
是否在 build;d 路径中添加了 v4 库？？
-
嗨，我有这个库，但似乎android找不到，问题出在同一个库中，我对其他一些类没有问题，比如ActionBar，我把我的MainActivy的代码以上，希望有人能阻止我
-
问题好像是android找不到android.support.v7.widget.SearchView;但我在图书馆有它
