如何使Action Bar SearchView填充整个操作栏？

Question

我试图在我的应用程序中创建action bar search，但在展开状态下，SearchView没有占用整个操作栏宽度（它仍然显示其他操作）！

那么，如何让SearchView填充完整的ActionBar区域（如在GMAIL应用程序中）？

Answer 1

以上解决方案均不适合我。设置SearchView的MaxWidth对我有用：

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    MenuInflater inflater = getMenuInflater();
    inflater.inflate(R.menu.menu_search, menu);
    SearchView searchView = (SearchView)menu.findItem(R.id.menu_search).getActionView();
    searchView.setMaxWidth(Integer.MAX_VALUE);

Answer 2

搞定了

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.my_swipe_tabbed, menu);

    MenuItem searchViewItem = menu.findItem(R.id.action_search);
    SearchView searchView = (SearchView) searchViewItem.getActionView();
    searchView.setIconifiedByDefault(false);
    ActionBar.LayoutParams params = new ActionBar.LayoutParams(ActionBar.LayoutParams.MATCH_PARENT, ActionBar.LayoutParams.MATCH_PARENT);
    searchView.setLayoutParams(params);
    searchViewItem.expandActionView();
    return true;
}


<menu xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:app="http://schemas.android.com/apk/res-auto"
        xmlns:tools="http://schemas.android.com/tools"
        tools:context=".MySwipeTabbedActivity" >
    <item android:id="@+id/action_search"
            android:title="Search"
            android:icon="@android:drawable/ic_menu_search"
            android:showAsAction="always|collapseActionView"
            android:actionViewClass="android.widget.SearchView"
            />
    <item android:id="@+id/action_share"
            android:title="Share"
            android:icon="@android:drawable/ic_menu_share"
            android:showAsAction="ifRoom" />
    <item android:id="@+id/action_settings"
            android:title="Settings"
            android:icon="@android:drawable/ic_menu_preferences"
            android:showAsAction="never" />
</menu>

[可选]避免搜索崩溃：

    searchViewItem.setOnActionExpandListener(new MenuItem.OnActionExpandListener() {
        @Override
        public boolean onMenuItemActionExpand(MenuItem item) {
            return true;
        }

        @Override
        public boolean onMenuItemActionCollapse(MenuItem item) {
            return false; //never collapse
        }
    });

Answer 3

@Hiep给出的答案是正确的我按照这些步骤来获得我的解决方案。但我正在使用ActionbarCompact lib，所以它需要做一些更改才能让它工作此解决方案只是修改后的答案Hiep，如果您使用appcompact

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
  xmlns:materialdesign="http://schemas.android.com/apk/res-auto" >

<item android:id="@+id/action_search"
      android:title="search"
      android:icon="@drawable/abc_ic_search_api_mtrl_alpha"
      materialdesign:showAsAction="always|collapseActionView"
      materialdesign:actionViewClass="android.support.v7.widget.SearchView" />

</menu>

在主类 onCreateOptionsMenu

中

  @Override
public boolean onCreateOptionsMenu(Menu menu) {

    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.my_swipe_tabbed, menu);

    MenuItem searchItem = menu.findItem(R.id.action_search);

    SearchView searchView = (SearchView) MenuItemCompat.getActionView(searchItem);



    // Get the SearchView and set the searchable configuration
    SearchManager searchManager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);

    searchView.setSearchableInfo(searchManager.getSearchableInfo(getComponentName()));


    ActionBar.LayoutParams params = new ActionBar.LayoutParams(ActionBar.LayoutParams.MATCH_PARENT, ActionBar.LayoutParams.MATCH_PARENT);
    searchView.setLayoutParams(params);
    searchView.setIconified(false);

     MenuItemCompat.expandActionView(searchItem);

   return super.onCreateOptionsMenu(menu);
}

避免searchView崩溃：如果你在Appcompact中使用上述方法，它会造成崩溃，所以使用这个解决方案来避免这种情况。

      MenuItemCompat.setOnActionExpandListener(searchItem, new MenuItemCompat.OnActionExpandListener() {

        /* (non-Javadoc)
         * @see android.support.v4.view.MenuItemCompat.OnActionExpandListener#onMenuItemActionExpand(android.view.MenuItem)
         */
        @Override
        public boolean onMenuItemActionExpand(MenuItem item) {

            return true;
        }

        /* (non-Javadoc)
         * @see android.support.v4.view.MenuItemCompat.OnActionExpandListener#onMenuItemActionCollapse(android.view.MenuItem)
         */
        @Override
        public boolean onMenuItemActionCollapse(MenuItem item) {

            return false;
        }
    });

谢谢

Answer 4

尝试此操作只会将所有其他项目设置为ifRoom

<item
    android:id="@+id/action_search"
    app:actionViewClass="android.support.v7.widget.SearchView"
    android:title="@string/action_search"
    app:showAsAction="always"/>

Answer 5

是的，我真的来晚了:) 但我想分享另一种替代解决方案。这个想法只是在showAsAction展开时隐藏分组菜单项。

步骤1： 对菜单项进行分组。请确保搜索视图项中的app:showAsAction="collapseActionView|always"是<group android:id="@+id/myMenuGroup"> <item android:id="@+id/actionSearch" android:icon="@drawable/ic_search" android:title="@string/search" app:actionViewClass="android.widget.SearchView" app:iconTint="@color/textColorVariant2" app:showAsAction="collapseActionView|always" /> <item android:id="@+id/actionFilter" android:icon="@drawable/ic_filter" android:orderInCategory="0" android:title="@string/filter" app:iconTint="@color/textColorVariant2" app:showAsAction="ifRoom" /> ..... </group>

onPrepareOptionsMenu()

步骤2：在override fun onPrepareOptionsMenu(menu: Menu?): Boolean { super.onPrepareOptionsMenu(menu) this.menu = menu // this.menu is a global scoped variable return true } 回调中获取菜单引用

MenuItem.OnActionExpandListener

第3步 将onMenuItemActionExpand()添加到您的活动中，并按如下所示实施onMenuItemActionExpand()和override fun onMenuItemActionExpand(p0: MenuItem?): Boolean { menu?.setGroupVisible(R.id.myMenuGroup, false) return true } override fun onMenuItemActionCollapse(p0: MenuItem?): Boolean { menu?.setGroupVisible(R.id.myMenuGroup, true) return true }

SearchView

即使存在其他ActionBar图标，这种方法也会将menu完全扩展到Yes内部
