    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_snacks);
        
                getActionBar().setBackgroundDrawable(new ColorDrawable(Color.parseColor("#33B5E5")));
                                
                getActionBar().setTitle("Snacks");
                
                getActionBar().setIcon(R.drawable.ic_launcher);
                
                getActionBar().setHomeButtonEnabled(true);
            
}
    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        getMenuInflater().inflate(R.menu.activity_main_actions, menu);
        
        MenuItem searchMenuItem = menu.findItem(R.id.action_search);
        
        SearchView searchView = (SearchView) MenuItemCompat.getActionView(searchMenuItem);
        
        searchView.setIconified(true);
    
        int searchImgId = getResources().getIdentifier("android:id/search_button", null, null);
        ImageView searchImg = (ImageView) searchView.findViewById(searchImgId);
        searchImg.setImageResource(R.drawable.ic_action_search);

        int searchDeleteImgId = getResources().getIdentifier("android:id/search_close_btn", null, null);
        ImageView searchDeleteImg = (ImageView) searchView.findViewById(searchDeleteImgId);
        searchDeleteImg.setImageResource(R.drawable.ic_action_delete);
        
        int searchSrcTextId = getResources().getIdentifier( "android:id/search_src_text", null, null);
        EditText searchEditText = (EditText) searchView.findViewById(searchSrcTextId);
        searchEditText.setTextColor(Color.WHITE);
        searchEditText.setHintTextColor(Color.LTGRAY);
        searchEditText.setHint("Search Here");
        
        searchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
            
            @Override
            public boolean onQueryTextSubmit(String s) {
                Toast.makeText(getApplicationContext(), "Entered Keyword is " + s,Toast.LENGTH_LONG).show();
                return true;
            }

            @Override
            public boolean onQueryTextChange(String s) {
                return false;
            }
        });
        
        return true;
    }
    
    
}

activity_main_actions.xml

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

    <item
        android:id="@+id/action_search"
        android:actionViewClass="android.widget.SearchView"
        android:icon="@drawable/ic_action_search"
        android:showAsAction="always"
        android:title="Search"/>
    <item android:id="@+id/action_contact"
        
          android:title="Contacts"
          android:showAsAction="always"/>
     <item android:id="@+id/settings"
        
          android:title="Contacts"
          android:showAsAction="never"/>
    

</menu>

styles.xml

    <!--
        Base application theme, dependent on API level. This theme is replaced
        by AppBaseTheme from res/values-vXX/styles.xml on newer devices.
    -->
    <style name="AppBaseTheme" parent="android:Theme.Light">
        <!--
            Theme customizations available in newer API levels can go in
            res/values-vXX/styles.xml, while customizations related to
            backward-compatibility can go here.
        -->
    </style>

    <!-- Application theme. -->
    <style name="AppTheme" parent="AppBaseTheme">
        <!-- All customizations that are NOT specific to a particular API-level can go here. -->
    </style>

</resources>

但是当我运行这个程序时，我得到了这个：-- 在这里，appname Snacks 没有显示。当我点击搜索视图时，我得到：--

这个搜索视图全面展开。我的代码哪里错了，我无法达到我的要求..

Answer 1

您可以在 searchView 上使用 setMaxWidth(int maxpixels) 方法。

    searchView.setMaxWidth(100);

尝试不同的尺寸，不确定哪个尺寸足够好:)

此外，如果联系人按钮不需要一直存在，您可以切换到 xml for

<item android:id="@+id/action_contact"
android:title="Contacts"
android:showAsAction="ifRoom"/>
