刷新菜單項動畫與ActionBarActivity /程序兼容性V21

Question

同樣的問題在這裏：Refresh menu item animation in ActionBarSherlock

除此之外，我想這樣做的API 11，使用ActionBarActivity和AppCompat v21 Material Design

refresh.xml

<?xml version="1.0" encoding="utf-8"?> 

<ImageView xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:layout_centerInParent="true" 
    android:src="@drawable/ic_menu_refresh" 
    android:background="#F00"/> 

MyFragment.java

private View mRefresh; 
private MenuItem mRefreshItem; 
private boolean mIsRefreshing; 
private Animation mRotate; 

@Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 

     mRotate = AnimationUtils.loadAnimation(getActivity(), R.anim.rotate); 
     mRotate.setRepeatCount(Animation.INFINITE); 
     mRotate.setAnimationListener(new Animation.AnimationListener() { 
      @Override 
      public void onAnimationStart(Animation animation) { 

      } 

      @Override 
      public void onAnimationEnd(Animation animation) { 

      } 

      @Override 
      public void onAnimationRepeat(Animation animation) { 
       if(!mIsRefreshing){ 
        mRefreshItem.getActionView().clearAnimation(); 
        mRefreshItem.setActionView(null); 
       } 
      } 
     }); 

     LayoutInflater inflater = (LayoutInflater) getActivity().getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
     mRefresh = inflater.inflate(R.layout.refresh, null); 
    } 

    @Override 
    public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) { 
     super.onCreateOptionsMenu(menu, inflater); 
     inflater.inflate(R.menu.menu, menu); 
     mRefreshItem = menu.findItem(R.id.action_refresh); 

     if(mIsRefreshing){ 
      mRefreshItem.setActionView(mRefresh); 
      mRefresh.startAnimation(mRotate); 
     } 
    } 

    @Override 
    public boolean onOptionsItemSelected(MenuItem item) { 
     switch(item.getItemId()){ 
      case R.id.action_refresh: 
       if(!mIsRefreshing) { 
        mRefreshItem.setActionView(mRefresh); 
        mRefresh.startAnimation(mRotate); 
        startTask(); 
       } 
       return true; 
      default: 
       return super.onOptionsItemSelected(item); 
     } 
    } 

動作視圖不與靜態圖標（紅色BG，這樣我可以看到視圖）對齊：

Answer 1

設置填充，以0：

<ImageView xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:layout_centerInParent="true" 
    android:src="@drawable/ic_menu_refresh" 
    android:padding="0dp" 
    style="@style/Widget.AppCompat.ActionButton"/>
