작업 표시 줄에 공유 버튼이 있습니까?

Question

현재 이미지를 공유해야하는 앱을 만들고 있습니다. XML을 완료하고 공유 단추가 나타나지만 클릭 할 수 없습니다. 나는 메뉴 팽창 곳

<?xml version="1.0" encoding="utf-8"?> 
<menu xmlns:android="http://schemas.android.com/apk/res/android" > 
    <item android:id="@+id/menu_item_scan" 
      android:icon="@drawable/scanlogo" 
      android:showAsAction="ifRoom" 
      android:title="Scan" /> 
    <item android:id="@+id/menu_item_share" 
      android:showAsAction="ifRoom" 
      android:title="Share" 
      android:actionProviderClass="android.widget.ShareActionProvider" /> 
</menu> 

이는 다음과 같습니다 :

다음은 XML에있는 버튼에 대한 내 코드입니다

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

이 모든 일을하고 나타나 있지만 클릭 할 수 없습니다. 클릭 가능하도록 시도하는 부분은 다음과 같습니다.

public boolean onOptionsItemSelected(MenuItem item) { 
     // Handle presses on the action bar items 
     switch (item.getItemId()) { 
      case R.id.menu_item_share: 
       Intent ShareIntent = new Intent(); 
       String pathofBmp = MediaStore.Images.Media.insertImage(getContentResolver(), QRMap,"QRCode", null); 
       Uri bmpUri = Uri.parse(pathofBmp); 
       ShareIntent.setAction(Intent.ACTION_SEND); 
       ShareIntent.putExtra(Intent.EXTRA_STREAM, bmpUri); 


    ShareIntent.setType("image/png"); 
      mShareActionProvider.setShareIntent(ShareIntent); 
      return true; 

     default: 
      return super.onOptionsItemSelected(item); 
    } 
} 

어떤 도움을 주실 수 있나요?

onOptionsItemSelected() 방법의 R.id.menu_item_share 사례를 삭제하십시오. 해당 코드를 onCreateOptionsMenu()과 같이 앱의 다른 곳으로 이동하여 ShareActionProvider이 표시되기 전에 구성하십시오.

예를 들어, 여기 one of my sample projects에서 ShareActionProvider를 구성 활동 :이 ActionBarSherlock의를 사용하는 내 경우에는
