ShareUtil进化版（支持并发）

Posted 2022-07-08 钰娘娘ynn

此处使用itemShares保存不同的share，防止因并发调用，导致数据混乱。

public class ShareUtils
    private static String DEFAULT_NAME = "default";

    private ShareUtils() 
    

    public static ShareUtils getInstance() 
        if(outterShare == null)
            outterShare = new ShareUtils();
        
        return outterShare;
    

    private SharedPreferences getShare() 
        if (sharedPreferences == null) 
            sharedPreferences = MyApp.getApp().getSharedPreferences(shareName, shareMode);
        
        return sharedPreferences;
    

    public ShareUtils resetShare() 
        commit();
        if (!this.shareName.equals(DEFAULT_NAME) || this.shareMode != Context.MODE_PRIVATE)

        this.shareMode = Context.MODE_PRIVATE;
        for(int i = itemShares.size()-1; i >=0; i--)
            if(itemShares.get(i) == null)
                itemShares.remove(i);
                continue;
