Question

我正在使用HashMap来获取列表视图适配器的值。问题是重复了我的HashMap的最后两个元素。发布此问题之前，我尝试了不同的解决方案。谢谢您的帮助。

这是我的HashMap的代码

org.slf4j:slf4j-log4j12:1.7.25

这是我的CustomListView适配器的代码。

CustomListView适配器

final String[] bookTitles = new String[]{
            "android-iconify",
            "Calligraphy",
            "SmartTabLayout",
            "android-viewpager-transformers",
            "Android-Rate",
            "FloatingActionButton",
            "TapTargetView",
            "MaterialDrawer"

    };
    final String[] authors = new String[]{

            "Version 2.2.2",
            "Version 2.2.0",
            "Version 1.6.1",
            "Version 1.0.1",
            "Version 1.0.1",
            "Version 1.6.4",
            "Version 1.11.0",
            "Version 6.0.8"


    };
    final String[] bookPages = new String[]{
            "Copyright 2015 Joan Zapata",
            "Copyright 2013 Christopher Jenkins",
            "Copyright (C) 2015 ogaclejapan\nCopyright (C) 2013 The Android Open Source Project",

            "Copyright 2018 Mike Penz"


    };
    ArrayList<HashMap<String, String>> authorList = new ArrayList<>();
    for (int i = 0; i < 8; i++){

        HashMap<String, String> data = new HashMap<>();
        data.put("title", bookTitles[i]);
        data.put("pages", bookPages[i]);
        data.put("author", authors[i]);


        authorList.add(data);

    }


    //Setup adapter
    customListViewAdapter = new CustomListViewAdapter(getApplicationContext(), authorList);
    listView.setAdapter(customListViewAdapter);

这是我得到的输出

output of CustomListView Adapter
remaining output of CustomListView Adapter

请帮助我。

尝试一下：

@Override
public View getView(int position, View convertView, ViewGroup parent) {
    View view;
    if (convertView == null){
        view = inflater.inflate(R.layout.list_row, null);
    } else {
        view = convertView;
    }

    TextView title = (TextView) view.findViewById(R.id.libraryName);
    TextView author = (TextView) view.findViewById(R.id.libraryVersion);
    TextView pages = (TextView) view.findViewById(R.id.libraryCopyright);

    HashMap<String, String> mBook = new HashMap<>();
    mBook = books.get(position);

    title.setText(mBook.get("title"));
    author.setText(mBook.get("author"));
    pages.setText(mBook.get("pages"));

    return view;
}

希望有帮助！

HashMap重复了Android Studio中的最后一个元素
