该错误是:
java.lang.NullPointerException.onCreateOptionsMenu(AddMyMarketsActivity.java:44)
我的code是:
My code is:
41 if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {
42 SearchManager searchManager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);
43 SearchView searchView = (SearchView) menu.findItem(R.id.menu_search).getActionView();
44 searchView.setSearchableInfo(searchManager.getSearchableInfo(getComponentName()));
Log.i("searchView", "set searchable configuration for searchView ");
有什么能与我的code中的问题?
What could be the problem with my code?
如果您在使用机器人支持libary,以显示你的动作条,一定要在你的搜索查看声明中使用正确的actionViewClass。
If you're using androids support libary to display your action bar, be sure you use the right actionViewClass in your SearchView declaration.
应应用:actionViewClass =android.support.v7.widget.SearchView
之后,你可以作为替代使用您的code试图获得而ActionView:
After that you can use as replacement for your code trying to get the ActionView:
MenuItem searchItem = menu.findItem(R.id.search_view);
SearchView searchView = (SearchView) MenuItemCompat.getActionView(searchItem);
在调用此之前一定要打电话getMenuInfalter()。膨胀(...)。
Be sure to call getMenuInfalter().inflate(...) before calling this.
