如何在Android設置在動作條意見的「動作按鈕」

Question

我的要求是： -

，當我點擊搜索按鈕，我想： - 因此，這裏是我的代碼： -

Snacks.java

public class Snacks extends Activity { 


    @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> 

但是當我運行這個程序，我得到這個： - 這裏，APPNAME 零食沒有顯示..當我點擊searchview我得到： -

此searchview擴展了全部。我的代碼中哪裏出錯我無法實現我的要求..

Answer 1

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

searchView.setMaxWidth(100); 

嘗試用不同的大小，不知道這將是足夠好:)

此外，如果接觸按鈕不需要在那裏，你可以在XML開關

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

所有的時間
