复制菜单项，每次它在打开溢出选项菜单

Question

我试图添加与XML代码的操作栏两个菜单项：

<?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" 
android:title="@string/search" 
android:icon="@drawable/ic_action_search" 
app:showAsAction="ifRoom" 
/> 
<item 
android:id="@+id/share" 
android:title="@string/share" 
android:icon="@drawable/ic_action_share" 
app:showAsAction="ifRoom" 
/> 

我的Java代码：

package com.erprakash.contacts; 
    import android.content.ContentUris; 
    import android.content.Context; 
    import android.content.Intent; 
    import android.database.Cursor; 
    //import android.net.Uri; 
    import android.provider.ContactsContract; 
    //import android.support.v7.app.ActionBar; 
    import android.support.v7.app.AppCompatActivity; 
    import android.os.Bundle; 
    import android.support.v7.widget.LinearLayoutManager; 
    import android.support.v7.widget.RecyclerView; 
    import android.support.v7.widget.Toolbar; 
    import android.view.Menu; 
    import android.view.MenuInflater; 
    import android.view.MenuItem; 
    import android.view.View; 
    import android.widget.Toast; 

    import java.util.ArrayList; 
    //import java.util.Comparator; 

    public class MainActivity extends AppCompatActivity { 

    private RecyclerView recyclerView; 
    private RecyclerView.Adapter adapter; 
private RecyclerView.LayoutManager layoutManager; 

ArrayList<Contact> arrayList = new ArrayList<>(); 
int img_id = R.drawable.image1; 
String name ; 
String number ; 
private int id; 
private Contact contact; 
@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 
    //Tool bar setting 
    //toolbar end 
    // Reading Contacts -----Working 
    Cursor phones = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,null,null, 
      ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME + " COLLATE NOCASE ASC"); 
    if (phones != null) { 
     while (phones.moveToNext()) 
     { 
      name = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME)); 
      number = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER)); 
      id = phones.getInt(phones.getColumnIndex(ContactsContract.CommonDataKinds.Photo.PHOTO_FILE_ID)); 
      if(id == 0){ 
       contact = new Contact(number, name, img_id); 
      }else { 
       contact = new Contact(number, name, id); 
      } 
      arrayList.add(contact); 
     } 
     phones.close(); 
    } 



    /** 
    name = getResources().getStringArray(R.array.person_name); 
    number = getResources().getIntArray(R.array.mobile_number); 
    int c = 0; 
    for(String Name: name) 
    { 
     Contact contact = new Contact(number[c],Name,img_id[c]); 
     c++; 
     arrayList.add(contact); 
    } 
    **/ 
    recyclerView = (RecyclerView)findViewById(R.id.rvMainContennt); 
    layoutManager = new LinearLayoutManager(this); 
    recyclerView.setLayoutManager(layoutManager); 
    recyclerView.setHasFixedSize(true); 
    adapter = new ContactAdapter(arrayList); 
    recyclerView.setAdapter(adapter); 


} 
//-------------Toolbar------------ 


@Override 
public boolean onCreateOptionsMenu(Menu menu) { 
    getMenuInflater().inflate(R.menu.menu_main,menu); 
    return true; 
} 

@Override 
public boolean onOptionsItemSelected(MenuItem item) { 
    int res_id = item.getItemId(); 
    if(res_id == R.id.search) 
    { 
     Toast.makeText(this.getApplicationContext(),"You have seleted search option",Toast.LENGTH_SHORT).show(); 
    } 
    return true; 
} 
@Override 
public boolean onPrepareOptionsMenu(final Menu menu) { 
    getMenuInflater().inflate(R.menu.menu_main, menu); 
    return super.onCreateOptionsMenu(menu); 
} 
} 

在预览中设计显示正确：

但处于运行状态：

而就点击选项菜单：

当我打开选项菜单内容被复制和推移，我已经寻找解决方案这一点，但我没有每次随时随地获取。帮我出来....在此先感谢

删除onPrepareOptionsMenu()。如下

@Override 
public boolean onPrepareOptionsMenu(final Menu menu) { 
    getMenuInflater().inflate(R.menu.menu_main, menu); 
    return super.onCreateOptionsMenu(menu); 
} 

更新onCreateOptionsMenu()：

@Override 
public boolean onCreateOptionsMenu(Menu menu) { 
    getMenuInflater().inflate(R.menu.menu_main, menu); 
    return true; 
} 

如果你想在Toolbar始终显示菜单项，然后如下更新menu_main.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" 
     android:title="@string/search" 
     android:icon="@drawable/ic_action_search" 
     app:showAsAction="always" /> 

    <item 
     android:id="@+id/share" 
     android:title="@string/share" 
     android:icon="@drawable/ic_action_share" 
     app:showAsAction="always" /> 
</menu>
