How to make SearchView always expanded in android?
提问by ruruma
I have SearchViewin the top of the layout (not in the action bar), is there anyway to force this Viewto be always expanded (opened)?
我SearchView在布局的顶部（不在操作栏中），无论如何要强制它View始终展开（打开）？
If not, i wish to place fancy image near it, is there anyway to make SearchViewhide this image when expanded (clicked/expanded)?
如果没有，我希望在它附近放置精美的图像，无论如何SearchView在展开（单击/展开）时隐藏此图像？

You can use the property android:iconifiedByDefault="false"on XML or set programatically setIconifiedByDefault(false). Acording to the documentation this property set the SearchViewexpanded like you want.
您可以android:iconifiedByDefault="false"在 XML 上使用该属性或以编程方式设置setIconifiedByDefault(false)。根据文档，此属性设置为SearchView您想要的扩展。
Take a look at SearchView.setIconifiedByDefault(boolean iconified)

SearchView searchView = (SearchView) menu.findItem(R.id.menu_search).getActionView();
searchItem.expandActionView();
and in menu file, use
并在菜单文件中，使用
showAsAction="ifRoom|collapseActionView"
If any query, feel free to comment.
如果有任何疑问，请随时发表评论。

如果您不需要打开键盘
searchView.clearFocus();

I am doing this into fragment , i done it by using
我正在将其放入片段中，我使用
searchItem.expandActionView();
but when user press back button it collapse so in collapse method i used
但是当用户按下后退按钮时它会崩溃，所以在我使用的折叠方法中
getActivity().getSupportFragmentManager().popBackStack();
// when it collapsed i am going back
Below is my solution in detail:
以下是我的详细解决方案：
search_menu.xml
search_menu.xml
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto">
<item android:id="@+id/search_contacts"
android:title="search"
android:icon="@drawable/search2"
app:showAsAction="ifRoom|collapseActionView"
app:actionViewClass="android.support.v7.widget.SearchView" >
</item>
</menu>
in fragment i used below code :
在片段中我使用了以下代码：
@Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
inflater.inflate(R.menu.search_menu, menu);
// Define the listener
MenuItemCompat.OnActionExpandListener expandListener = new MenuItemCompat.OnActionExpandListener() {
@Override
public boolean onMenuItemActionCollapse(MenuItem item)
{
getActivity().getSupportFragmentManager().popBackStack();
// Do something when action item collapses
return true; // Return true to collapse action view
}
@Override
public boolean onMenuItemActionExpand(MenuItem item)
{
// Do something when expanded
return true; // Return true to expand action view
}
};
MenuItem searchItem = menu.findItem(R.id.search_contacts);
// Assign the listener to that action item
MenuItemCompat.setOnActionExpandListener(searchItem, expandListener);
// Any other things you have to do when creating the options menu…
SearchView searchView =
(SearchView) MenuItemCompat.getActionView(searchItem);
//searchView.setIconifiedByDefault(false);
searchItem.expandActionView(); // when fragment opens it expanded auto
searchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
@Override
public boolean onQueryTextSubmit(String query) {
return false;
}
@Override
public boolean onQueryTextChange(String newText)
{
seachViewFunction(newText); // in searchViewFunction(newText); i am doing my things
return false;
}
});
super.onCreateOptionsMenu(menu, inflater);
}
