如何JSONArray转换成的ListView？ [英] How to convert JSONArray to ListView?

问题描述

我有一个code这不下面 -

I have a code which does following -

1. 通过HttpClient的连接到Web服务到PHP文件
2. 从一个SQL查询返回的结果
3. 在返回格式是jArray（一JSONArray），其中

for(int i=0; i < jArray.length() ; i++) {
    json_data = jArray.getJSONObject(i);
    int id=json_data.getInt("id");
    String name=json_data.getString("name");
    Log.d(name,"Output");
}

当我看着LogCat中，我看到查询所有的名，每条记录都打印出来。我只需要插入这些结果变成一个ListView。我怎样才能做到这一点？

When I look at the LogCat, I see all the "names" of the query, Each record is printed. I just need to plug these results into a ListView. How can I accomplish this ?

PS - 我没有一个ArrayAdapter一个单独的类。难道这是什么原因呢？

PS - I do not have a separate class for an ArrayAdapter. Could this be the reason ?

推荐答案

如果你只是想显示textViews列表你不需要重写任何东西，你可以添加所有的项目到一个ArrayList和使用arrayAdapter。

If you just want to display a list of textViews you don't need to override anything, you can just add all of the items into an arrayList and use an arrayAdapter.

把你的XML列表视图名为Android的：清单，然后用您要使用的TextView的创建arrayAdapter

Put a list view in your xml that is named android:list and then create your arrayAdapter with the textView you want to use.

在所有你所要做的就是调用setListAdapter（mArrayAdapter），它应该填充您的列表中。

After that all you have to do is call setListAdapter(mArrayAdapter) and it should populate your list.

ArrayList<String> items = new ArrayList<String>();
for(int i=0; i < jArray.length() ; i++) {
    json_data = jArray.getJSONObject(i);
    int id=json_data.getInt("id");
    String name=json_data.getString("name");
    items.add(name);
    Log.d(name,"Output");
}

ArrayAdapter<String> mArrayAdapter = new ArrayAdapter<String>(this,  
           android.R.layout.simple_expandable_list_item_1, items));
setListAdapter(mArrayAdapter)

希望这有助于！
