Android:无法将jsonobject显示到listView中

时间:2017-04-27 17:17:03

标签: android listview android-arrayadapter listview-adapter

我正在使用android studio开发一个Android应用程序,该应用程序正在使用一个宁静的Web服务,我无法将结果显示到我的listView中,但是当我尝试它时,我总是得到一个列表视图,其中包含我认为我得到的地址这种格式:

com.example.projetmonitoringapplication.listez$Dabl@d593975

注意我有4个元素因为结果重新生成,在我的日志中我可以看到我得到了对象,我甚至可以从ArrayList中获取一个元素。 我认为问题出在适配器上,或者我不知道,有人可以告诉我该怎么办。

我尝试了两个东西,一个返回该结果的arrayAdapter和一个返回空列表视图的普通适配器。 你可以在我的代码上看到它

这个活动,我甚至在评论中尝试了很多东西:

活动代码包含很多方法,不用担心我只是尝试了很多东西而且所有这些代码表都没有工作。

答案 0 :(得分:0)

未在listview中获取数据的原因是您尝试将ArrayList分配给默认数组适配器而不是适配器。

此外,它不是在活动中放置适配器和asyncTask的标准方法。最好为适配器和异步任务创建单独的java文件。

让我们来编码。

在适配器中,始终建议传递上下文,布局和ArrayList以提高可读性。

在适配器中

放置此代码

    Context context;
    ArrayList<listez.Dabl> list;
    adapter(Context context,int resId,ArrayList<listez.Dabl> list) {
        super(context, resId, list);
        this.context=context;
        this.list=list;
    }

而不是

  adapter() {
        super(listez.this, android.R.layout.simple_list_item_1, arrayOfWebData);
    }

以及适配器类populateFrom功能

您正尝试在textview中显示整数。它可能会引发错误。

放置此

 idd.setText(String.valueOf(r.getId()));

而不是

 idd.setText(r.getId());

在AsyncTask onPost中执行函数

将数据添加到ArrayList

后,最后放置此代码
  list( ArrayList<Dabl> arrayOfWebData);

然后在 listez class

中插入此函数
    public void list( ArrayList<Dabl> arrayOfWebData){
        ListView myListView = (ListView)findViewById(R.id.lstdab);
        adapter arrayAdapter = new adapter(MainActivity.this, android.R.layout.simple_list_item_1,arrayOfWebData );
        myListView.setAdapter(arrayAdapter);
    }
