我的工具栏中有一个搜索图标,用于搜索RecyclerView列表。
图1:
单击图标时,工具栏显示SearchView的setQueryHint“ 在这里搜索......“。
图2:
在SearchView行输入字符时,在本例中为数字“4”,然后在RecyclerView列表中搜索。如果找不到该字符,则字符右侧会出现一个关闭按钮“x”:
图3:
我的问题是,单击关闭按钮“x”时的默认行为是关闭SearchView,它将视图返回到Pic 1,即初始图标View。我想让View返回到SearchView行“Search here ...”,这是Pic 2.我尝试在mCloseButton.OnClickListener中的SearchView上使用setQueryHint,但它不起作用。请参阅下面的mCloseButton OnClickListener()中的**,以了解我尝试过的其他片段无法正常工作。我在这里缺少什么?
menu.xml
<item android:id="@+id/action_search"
android:title="@string/search_title"
android:icon="@drawable/ic_action_search"
app:actionViewClass="android.support.v7.widget.SearchView"
app:showAsAction="always|collapseActionView" />
Activity
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.cardview_menu, menu);
final MenuItem searchItem = menu.findItem(R.id.action_search);
if (adapter == null || adapter.getItemCount() == 0) {
searchItem.setVisible(false);
} else {
searchItem.setVisible(true);
SearchManager searchManager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);
final SearchView mSearchView = (SearchView) MenuItemCompat.getActionView(searchItem);
mSearchView.setSearchableInfo(searchManager.getSearchableInfo(getComponentName()));
final EditText mSearchEditText = (EditText)mSearchView.findViewById(android.support.v7.appcompat.R.id.search_src_text);
final ImageView mCloseButton = (ImageView) mSearchView.findViewById(android.support.v7.appcompat.R.id.search_close_btn);
mSearchView.setQueryHint(" Search here...");
MenuItemCompat.setOnActionExpandListener(searchItem, new MenuItemCompat.OnActionExpandListener() {
@Override
public boolean onMenuItemActionExpand(MenuItem item) {
return true; // Return true to expand action view
}
@Override
public boolean onMenuItemActionCollapse(MenuItem item) {
adapter.clear();
adapter.addAll(allList);
return true; // Return true to collapse action view
}
});
mCloseButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
//Clear the query
mSearchView.setQuery("",false);
// below lines were all tried and do not work
**mSearchView.setQueryHint(" Search here...");**
**mSearchView.setIconified(false);**
**mSearchView.onActionViewCollapsed);**
**MenuItemCompat.expandActionView(searchitem);**
adapter.clear();
adapter.addAll(allList);
}
});
...
return super.onCreateOptionsMenu(menu);
}
答案 0 :(得分:0)
尝试使用mSearchView.setIconified(false)。
