上ActionBarSherlock菜单项

Question

添加badgeview我想在动作条菜单项

添加badge但数字图标没显示。

这里是我迄今

public class Main extends SherlockFragmentActivity 
{ 
    private Fragment menuFrag=null; 
    private MenuItem menuMsg=null; 
    private BadgeView badge=null; 

    @Override 
    protected void onCreate(Bundle savedInstanceState) 
    { 
    //Do my stuff... 
    initUI(); 
    } 

    private void initUI() 
    { 
    FragmentManager fm=getSupportFragmentManager(); 
    FragmentTransaction ft=fm.beginTransaction(); 
    menuFrag=fm.findFragmentByTag("f1"); 
    if(menuFrag==null) 
    { 
     menuFrag=new MenuFragment(); 
     ft.add(menuFrag, "f1"); 
    } 
    ft.commit(); 

    // badge=new BadgeView(Main.this, (View)menuMsg); //Not working 
    badge=new BadgeView(Main.this, menuMsg.getActionView()); //Not working as well 
    badge.setBackgroundResource(R.drawable.badge_ifaux); 
    badge.setTextSize(10); 
    badge.setBadgeMargin(2); 
    badge.setText("1"); 
    badge.show(); 
    } 

    private class MenuFragment extends SherlockFragment 
    { 
    @Override 
    public void onCreate(Bundle savedInstanceState) 
    { 
     super.onCreate(savedInstanceState); 
     setHasOptionsMenu(true); 
    } 

    public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) 
    { 
     menu.add("Cloud").setIcon(R.drawable.icon_cloud).setShowAsAction(MenuItem.SHOW_AS_ACTION_ALWAYS); 
     menu.add("List").setIcon(R.drawable.icon_list).setShowAsAction(MenuItem.SHOW_AS_ACTION_ALWAYS); 
     menuMsg=menu.add("Msg"); 
     menuMsg.setIcon(R.drawable.icon_msg).setShowAsAction(MenuItem.SHOW_AS_ACTION_ALWAYS); 
    } 

    @Override 
    public boolean onOptionsItemSelected(MenuItem item) 
    { 
     Toast.makeText(Main.this, "Got click: " + item.toString(), Toast.LENGTH_SHORT).show(); 
     return true; 
    } 
    } 
} 

哪里做错了呢？

Answer 1

RRTW，

您使用本身不支持徽章动作条菜单项目库。

https://github.com/jgilfelt/android-viewbadger/commit/e08c3a78cb92c0c8587790b15e73434f972912cf

然而，这并不意味着你不能得到它的工作。

的设置将是如下（这里假设你已经在你的项目中viewbager库设置）

（1）onCreateOptionsMenu - >（2）添加R.menu.your_place_holder_item - >（3）setActionView用自定义xml布局 - >（4）findViewById的MenuItem对象来获取您的按钮/视图来设置徽章。

1）设置你onCreateOptionsMenu并创建了R.menu.actionbar_menu_messages

R.menu.actionbar_menu_messages：

<menu xmlns:android="http://schemas.android.com/apk/res/android" 
     > 
    <item android:showAsAction="ifRoom" android:icon="@drawable/action_bar_pk_content_email" 
     android:id="@+id/menuMessages" android:title="More"></item> 

</menu> 

onCreateOptionsMenu：

public boolean onCreateOptionsMenu(Menu menu) { 
    super.onCreateOptionsMenu(menu); 
    MenuInflater inflater = getSupportMenuInflater(); //If you are using the support library otherwise use: getMenuInflater(); 
    inflater.inflate(R.menu.actionbar_menu_messages, menu); 
    this.setupMessagesBadge(menu.findItem(R.id.menuMessages)); //This is part of step 2 
    return true; 
} 

2）定义了common_messages_indicator

R.layout.common_messages_indicator：

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android" 
      android:layout_width="64dp" 
      android:layout_height="fill_parent" 
      android:paddingTop="10dp" 
      android:gravity="center"> 
    <ImageView 
     android:id="@+id/imgMessagesIcon" 
     android:layout_width="32dp" 
     android:layout_height="fill_parent" 
     android:layout_gravity="center" 
     android:scaleType="fitCenter" 
     android:src="@drawable/messages_button" 
     android:background="@android:color/transparent" 
     android:focusable="false" 
     /> 

    </FrameLayout> 

执行setActionView到自定义XML布局添加到

的ActionView

private void setupMessagesBadge(final MenuItem msgItem) { 
    msgItem.setActionView(R.layout.common_messages_indicator); 

    if(msgItem.getActionView().findViewById(R.id.imgMessagesIcon) != null) 
    { 
     ImageView imgMessagesIcon = ((ImageView)msgItem.getActionView().findViewById(R.id.imgMessagesIcon)); 

     imgMessagesIcon.setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View view) { 
       //Your click on the action bar item will be captured here 
      } 
     }); 
     int badgeCnt = 20;// Add your count here 
     if(messageCenterBadge == null && badgeCnt > 0) 
     { 
      //imgMessagesIcon is the imageview in your custom view, apply the badge to this view. 
      messageCenterBadge = new BadgeView(this, imgMessagesIcon); 
      messageCenterBadge.setBadgePosition(BadgeView.POSITION_TOP_RIGHT); 
      messageCenterBadge.setBadgeMargin(0); 
      messageCenterBadge.setTextSize(12); 
      messageCenterBadge.setText(String.valueOf(badgeCnt)); 
      messageCenterBadge.show(); 
     } 
     else if(messageCenterBadge != null && badgeCnt > 0) 
     { 
      messageCenterBadge.setText(String.valueOf(badgeCnt)); 
      messageCenterBadge.show(); 
     } 
     else if(messageCenterBadge != null && badgeCnt == 0) { 
      messageCenterBadge.hide(); 
     } 
    } 
}
