ArrayIndexOutOfBoundsException错误ANDROID

Question

我对这段代码有疑问：

for(int i=0; i<jArray.length();i++){
    json_data = jArray.getJSONObject(i);
    String name = json_data.getString("post_title");
    String created_date = json_data.getString("created_date");
    String outPut = name + "-" + created_date;
    postList.add(createPost("blog_posts", outPut));
    Log.e("log_tag", "Name: "+name);
}

我收到了这个错误。

这个问题可能有重复，但我试过搜索答案，但没有一个帮助。任何帮助将不胜感激。

删除此代码块时，此方法正常。

SimpleAdapter simpleAdapter = new SimpleAdapter(
    MainActivity.this, postList, R.layout.postlist,
    new String[] {"posts"},
    new int[] {R.id.post_title,R.id.posted_date});
    listView.setAdapter(simpleAdapter);


private HashMap<String, String> createPost(
    String name, String created_date) {
    HashMap<String, String> blogitem = new HashMap<String, String>();
    blogitem.put(name, created_date);
    return blogitem;
}
