ActionBar SearchView not fully expanding in landscape mode

问题:

When using the action bar search interface, the widget expands to occupy the full width of the screen in portrait mode, but stops short in landscape mode.

Is there a way to set the expansion layout params on the SearchView to fully fill the action bar when the user is typing a search?

Note: I'm not currently using ActionBar Sherlock

Edit: Here's what I did to get it to extend the full width.

searchView.setOnSearchClickListener(new OnClickListener() {     private boolean extended = false;      @Override     public void onClick(View v) {         if (!extended) {             extended = true;             LayoutParams lp = v.getLayoutParams();             lp.width = LayoutParams.MATCH_PARENT;         }     }  });

Did you try something like that?

editView.setOnKeyListener(new OnKeyListener() {     private boolean extended = false;      @Override     public boolean onKey(View v, int keyCode, KeyEvent event) {         if (!extended && event.getAction() == KeyEvent.ACTION_DOWN) {             extended = true;             LayoutParams lp = v.getLayoutParams();             lp.width = LayoutParams.MATCH_PARENT;         }          return false;     }  });

MenuItemCompat's SearchView has a property named maxWidth.

    final MenuItem searchItem = menu.findItem(R.id.action_search);     final SearchView searchView = (SearchView) MenuItemCompat.getActionView(searchItem);     searchView.setMaxWidth(xxx); 

use screen width instead of xxx offcourse

I figured out a solution for fully expanding the search view in landscape and to also have the action view already expanded when the activity is created. Here how it works:

1.First create an xml file in your res-menu folder called for example : searchview_in_menu.xml. Here you would have the following code:

    <?xml version="1.0" encoding="utf-8"?>     <menu xmlns:android="http://schemas.android.com/apk/res/android" >         <item android:id="@+id/action_search"               android:title="@string/search"               android:icon="@android:drawable/ic_menu_search"               android:actionLayout="@layout/searchview_layout" />     </menu> 

Note: "@string/search" - looks something like this in the res-strings.xml:

    <string name="search">Search</string> 

2.Second create the layout referred above ("@layout/searchview_layout") in res-layout folder. The new layout: searchview_layout.xml will look like this:

    <?xml version="1.0" encoding="utf-8"?>     <SearchView xmlns:android="http://schemas.android.com/apk/res/android"       android:id="@+id/search_view_layout"       android:layout_width="match_parent"       android:layout_height="wrap_content"/> 

Note: Here we are setting the search view width to match the width of its parent( android:layout_width="match_parent")

3.In your MainActivity class or in the activity that has to implement the Search View write in the onCreateOptionsMenu() method the following code:

@Override     public boolean onCreateOptionsMenu(Menu menu) {         super.onCreateOptionsMenu(menu);         MenuInflater inflater = getMenuInflater();         inflater.inflate(R.menu.searchview_in_menu, menu);         //find the search view item and inflate it in the menu layout         MenuItem searchItem = menu.findItem(R.id.action_search);         mSearchView = (SearchView) searchItem.getActionView();         //set a hint on the search view (optional)         mSearchView.setQueryHint(getString(R.string.search));         //these flags together with the search view layout expand the search view in the landscape mode         searchItem.setShowAsActionFlags(MenuItem.SHOW_AS_ACTION_COLLAPSE_ACTION_VIEW                 | MenuItem.SHOW_AS_ACTION_ALWAYS);         //expand the search view when entering the activity(optional)         searchItem.expandActionView();         return true; } 

回答4:

Adjust the width layout param to MATCH_PARENT, that way the SearchView will fully expand in either portrait or landscape

ViewGroup.LayoutParams layoutParams = mSearchView.getLayoutParams(); layoutParams.width = ViewGroup.LayoutParams.MATCH_PARENT; 

回答5:

For ActionBarCompat use this:

    MenuItemCompat.setShowAsAction(searchItem, MenuItem.SHOW_AS_ACTION_COLLAPSE_ACTION_VIEW             | MenuItem.SHOW_AS_ACTION_ALWAYS);     MenuItemCompat.expandActionView(searchItem); 

回答6:

Use this (100%):

mSearchView = (SearchView) searchItem.getActionView();     mSearchView.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT));
