Android GridView Selector Issue

Question

我在我的應用程序中使用了一個由我創建的自定義選擇器的StaggeredGridView，但我必須得到一些可怕的錯誤，因爲當我在gridview中選擇一個項目時，所有項目都會改變它們的顏色變綠。

這裏是gridview的項目代碼：

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:app="http://schemas.android.com/apk/res-auto" 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" 
    android:orientation="vertical" 
    android:background="@drawable/grid_item_selector"> 

    <RelativeLayout 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content"> 

     <ro.gebs.zonizbeacon.ui.custom.ScaledNetworkImageView 
      android:id="@+id/imageView1" 
      android:layout_width="match_parent" 
      android:layout_height="wrap_content" /> 

     <ro.gebs.zonizbeacon.ui.custom.AngledTextView 
      android:id="@+id/expired_tv" 
      android:layout_width="@dimen/size_favorite_angle_text" 
      android:layout_height="@dimen/size_favorite_angle_text" 
      app:angledText="@string/expired" 
      app:backgroundColor="@android:color/holo_orange_dark" 
      app:angledTextColor="@android:color/white" 
      app:angledTextSize="@dimen/font_size_plus" /> 
    </RelativeLayout> 


    <ro.gebs.zonizbeacon.ui.custom.fonts.CustomFontTextView 
     android:id="@+id/store_name" 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" 
     android:padding="@dimen/default_padding" 
     android:textSize="@dimen/font_size_normal" 
     android:text="Zara" 
     app:fontName="Bold" /> 

    <ro.gebs.zonizbeacon.ui.custom.fonts.CustomFontTextView 
     android:id="@+id/offer_text" 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" 
     app:fontName="Regular" 
     android:paddingLeft="@dimen/default_padding" 
     android:paddingRight="@dimen/default_padding" 
     android:paddingBottom="@dimen/default_padding" 
     android:textSize="@dimen/font_size_small" 
     android:text="@string/info_about" /> 

</LinearLayout> 

這是我的選擇：

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

<selector xmlns:android="http://schemas.android.com/apk/res/android"> 
    <item android:state_enabled="true" android:state_pressed="true" android:drawable="@color/green_main_color" /> 
    <item android:state_enabled="true" android:state_focused="true" android:drawable="@color/green_main_color" /> 
    <item android:state_enabled="true" android:state_selected="true" android:drawable="@color/green_main_color" /> 
    <item android:drawable="@android:color/white" /> 
</selector> 

這是我的適配器類：

public class FavoritesAdapter extends ArrayAdapter<Offer> { 
    LayoutInflater mLayoutInflater; 

    public FavoritesAdapter(Context context, List<Offer> objects) { 
     super(context, 0, objects); 
     mLayoutInflater = LayoutInflater.from(context); 
    } 

    /* @Override 
    public long getItemId(int position) { 
     return position; 
    }*/ 

    @Override 
    public View getView(int position, View convertView, ViewGroup parent) { 
     ViewHolder holder; 

     if (convertView == null) { 
      convertView = mLayoutInflater.inflate(R.layout.item_favorite_offer, null); 
      holder = new ViewHolder(); 
      holder.imageView = (ScaledNetworkImageView) convertView.findViewById(R.id.imageView1); 
      holder.offerText = (CustomFontTextView) convertView.findViewById(R.id.offer_text); 
      holder.storeName = (CustomFontTextView) convertView.findViewById(R.id.store_name); 
      holder.expiredTv = (AngledTextView) convertView.findViewById(R.id.expired_tv); 
      convertView.setTag(holder); 
     } else { 
      holder = (ViewHolder) convertView.getTag(); 
     } 
     //holder.offerText.setText("POSITION + "+position); 
     final Offer offer = getItem(position); 
     Date d = Calendar.getInstance().getTime(); 

     if (offer.getActiveUntil() < d.getTime()) { 
      holder.expiredTv.setVisibility(View.VISIBLE); 
     } else { 
      holder.expiredTv.setVisibility(View.INVISIBLE); 
     } 


     ImageUtils.load(holder.imageView, offer.getPngLink(), R.drawable.image_placeholder, R.drawable.image_placeholder); 
     holder.offerText.setText(offer.getDescription()); 
     holder.storeName.setText(offer.getStoreName()); 

     return convertView; 
    } 

    static class ViewHolder { 
     AngledTextView expiredTv; 
     ScaledNetworkImageView imageView; 
     CustomFontTextView offerText; 
     CustomFontTextView storeName; 
    } 

} 

，並在我的片段：

@Override 
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { 
     final View view = inflater.inflate(R.layout.fragment_favorites, container, false); 

     gridView = (StaggeredGridView) view.findViewById(R.id.staggeredGridView1); 
     //gridView.setSelector(new ColorDrawable(getResources().getColor(R.color.green_main_color))); 
     gridView.setSelector(new ColorDrawable(Color.TRANSPARENT)); 
     emptyText = (CustomFontTextView) view.findViewById(R.id.empty_grid_view); 

     int margin = getResources().getDimensionPixelSize(R.dimen.default_padding); 
     int itemMargin = getResources().getDimensionPixelSize(R.dimen.padding_tell_button); 

     gridView.setItemMargin(itemMargin); // set the GridView margin 
     gridView.setPadding(margin, margin, margin, 0); // have the margin on the sides as well 

     mFavoritesAdapter = new FavoritesAdapter(getActivity(), new ArrayList<Offer>()); 
     mFavoritesAdapter.setNotifyOnChange(false); 

     gridView.setAdapter(mFavoritesAdapter); 
     gridView.setOnItemClickListener(new StaggeredGridView.OnItemClickListener() { 
      @Override 
      public void onItemClick(StaggeredGridView parent, View view, int position, long id) { 
       Offer o = mFavoritesAdapter.getItem(position); 
       if (o != null) { 
        Intent intent = new Intent(getActivity(), WebViewActivity.class); 
        intent.putExtra(WebViewActivity.BUNDLE_HTML_LINK, o.getHtmlLink()); 
        intent.putExtra(WebViewActivity.STORE_NAME, o.getStoreName()); 
        startActivity(intent); 
       } 
       //getActivity().finish(); 
      } 
     }); 

     gridView.setOnItemLongClickListener(mOnItemLongClickListener); 


     //restartLoader(LOADER_FAVORITES); 

     return view; 
    } 

任何想法爲什麼它可能是錯的？

也許你的listitems得到的焦點狀態（雖然不是打算）。我始終使用選擇建立這樣的：

<selector xmlns:android="http://schemas.android.com/apk/res/android" 
     android:exitFadeDuration="@android:integer/config_mediumAnimTime" > 
    <item android:state_selected="true" android:drawable="@color/green_bit_transparent"/> 
    <item android:state_pressed="false" android:state_focused="true" android:state_selected="false" android:drawable="@color/green_bit_transparent" /> 
    <item android:state_pressed="true" android:state_selected="false" android:drawable="@color/green" /> 
    <item android:drawable="@android:color/transparent" /> 
</selector>
