如何设置MenuItemClickListener要搜索查看在辅助工具栏 [英] How to set the MenuItemClickListener for a SearchView at a secondary Toolbar
问题描述
我试图几个小时设置在底部（二级）android.support.v7.widget.ToolBar简单android.support.v7.widget.SearchView。
我已经使用另一个工具栏往上顶设置为一个动作条，所以我不能用在活动 onCreateOptionsMenu 回调，相反，我必须建立一个 OnMenuItemClickListener（）。我已阅读 Android的搜索查看教程，的本教程了解工具栏。
i am trying for hours to setup a simple android.support.v7.widget.SearchView in a bottom (secondary) android.support.v7.widget.ToolBar.
I am already using another Toolbar up top set up as an ActionBar, so i cannot use the onCreateOptionsMenu callback on activity, instead i have to set up an OnMenuItemClickListener() . I have read the Android SearchView Tutorial, this tutorial about Toolbars.

如果我喜欢的运行它，我碰到一个搜索查看，但没有我的安卓图标=@绘制/ ic_search_white，而不是我得到的谷歌搜索查看图标，如果我点击它，我得到一个很好的编辑文本，明确和搜索功能，但无论怎样我输入或preSS，里面的Log.d没有在 Toolbar.OnMenuItemClickListener 被解雇了。 （我不能发布，因为口碑的图像）。
如果我使用的android：actionViewClass =android.support.v7.widget.SearchView而不是指南：actionViewClass =android.support.v7。 widget.SearchView让我的安卓图标=@绘制/ ic_search_white，如果我点击它，我得到上NPE searchView.setOnCloseListener（新OnCloseListener（）{，因为搜索查看为null。
If i run it like that, i get a SearchView but without my android:icon="@drawable/ic_search_white", instead i get the google SearchView icon, if i tap it i get a nice edit text, with clear and search functions, but no matter what i input or press, NONE of the Log.d inside the Toolbar.OnMenuItemClickListenergets fired up. (I cannot post images because of reputation).
If i use android:actionViewClass="android.support.v7.widget.SearchView" instead of guide:actionViewClass="android.support.v7.widget.SearchView" i get my android:icon="@drawable/ic_search_white" , if i tap it, i get an NPE on searchView.setOnCloseListener(new OnCloseListener() { because searchView is null .
我试着做什么在这里这个的相关问题， <一href=\"http://stackoverflow.com/questions/18832890/android-nullpointerexception-on-searchview-in-action-bar\">this但没有成功为止。
I tried doing whats on this related question here, and this but no success so far.

更新23/09/15
我找不到什么好的解决办法，所以，因为我只是想获得搜索查看项目，我决定潜入它像这样：
Updated 23/09/15 I could not find any good solution, so, since i only wanted to get the SearchView item i decided to hack into it like so:
protected void onCreate(final Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
if(savedInstanceState==null){
FragmentManager fragmentManager = getSupportFragmentManager();
FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
fragmentTransaction.add(R.id.dlHomepageSpace, HomepageFragment.newInstance(mLanguage), HOMEPAGE_BUTTONS_TAG);
fragmentTransaction.commit();
}
mSearchState = SearchState.NOSEARCH;
mBottomToolbar = (Toolbar) findViewById(R.id.bottomToolbar);
mBottomToolbar.inflateMenu(R.menu.bottom_toolbar);
// Here we set the search view toolbar functions
if(mBottomToolbar.getMenu().size() > 0){
SearchManager searchManager = (SearchManager) HomepageActivity.this.getSystemService(Context.SEARCH_SERVICE);
MenuItem searchMenuItem = mBottomToolbar.getMenu().getItem(mBottomToolbar.getMenu().size()-1);
mSearchView = (SearchView) searchMenuItem.getActionView();
if (mSearchView != null) {
mSearchView.setSearchableInfo(searchManager.getSearchableInfo(HomepageActivity.this.getComponentName()));
}
mSearchView.setOnCloseListener(new OnCloseListener() {
@Override
public boolean onClose() {
Log.d(TAG, "onClose");
mBottomToolbar.getMenu().getItem(mBottomToolbar.getMenu().size()-1).collapseActionView();
switchToFab();
return false;
}
});
MenuItemCompat.setOnActionExpandListener(searchMenuItem, new MenuItemCompat.OnActionExpandListener() {
@Override
public boolean onMenuItemActionExpand(MenuItem item) {
Log.d(TAG, "onMenuItemActionExpand");
return true; // KEEP IT TO TRUE OR IT DOESN'T OPEN !!
}
@Override
public boolean onMenuItemActionCollapse(MenuItem item) {
Log.d(TAG, "onMenuItemActionCollapse");
switchToFab();
return true;
}
});
}
}
@Override
protected void onNewIntent(Intent intent) {
Log.d(TAG, "onNewIntent");
if(isSearchAction(intent)){
ArrayList<Detail> list = (ArrayList<Detail>) getListData(intent.getStringExtra(SearchManager.QUERY));
if(list.isEmpty()){
Toast.makeText(this, R.string.no_search_results_en, Toast.LENGTH_LONG).show();
}
} else {
ExtendedListFragment searchFragment = (ExtendedListFragment) getSupportFragmentManager().findFragmentByTag(HOMEPAGE_SEARCH_TAG);
mResultsList = list;
mSearchState = SearchState.SEARCH_LIST_SCREEN;
if(searchFragment==null){
FragmentTransaction fragmentTransaction = getSupportFragmentManager().beginTransaction();
fragmentTransaction.addToBackStack(null);
fragmentTransaction.replace(R.id.dlHomepageSpace, ExtendedListFragment.newInstance(list), HOMEPAGE_SEARCH_TAG);
fragmentTransaction.commit();
} else {
searchFragment.setDetailList(list);
}
}
}
}
private boolean isSearchAction(Intent intent) {
Log.d(TAG, "handleIntent");
if (Intent.ACTION_SEARCH.equals(intent.getAction())) {
Log.d(TAG, "ACTION_SEARCH");
return true;
}
return false;
}
在本质上，我只看到工具栏，并获得独一无二的项目进去，我投它作为一个菜单项，然后我得到的搜索查看的菜单项的而ActionView。
喜欢它的工作原理和我没有使用 setOnMenuItemClickListener（）。当我在视图中轻点，我可以输入进去（我不需要 mSearchView.OnQueryTextListener 不过，我已经看到了它的工作），当我$ P $的PSS键盘我得到的 onNewIntent（）调用工作放大镜。
In essence, i just look into the toolbar, and obtain the one and only Item into it, i cast it as a MenuItem and then i get the SearchView as the ActionView of the MenuItem.
Like that it works and i do not have to use setOnMenuItemClickListener() . When i tap in the view, i can type into it (i do not need a mSearchView.OnQueryTextListener but, i have seen it working) , when i press the magnifying glass on the keyboard i get the onNewIntent() call working.
