如何在 strings.xml 或资产中存储数组并在 ListViewAdapter 中使用
How to store arrays in strings.xml or assets and use in ListViewAdapter
我想在 ListViewAdapter 中创建超过 1500 个 LyricsFullDetail，但我的问题是我不想在 ListViewAdapter.java 中硬编码 Lyrics Full Detail。我想存储歌词的全部细节并从 Strings.xml 或资产文件夹中读取。音乐文件保存在原始文件夹中。
如果你帮我举个例子，我将不胜感激fix.thanks下面是我的代码。
这是我重复了 1500 次的 itemClick 代码，它给了我 'code too large error'
这就是为什么我努力将它保存在资产文件夹之类的地方并在 ListViewAdapter
中读取的原因

您可以从 strings.xml 中的字符串数组创建一个列表，然后可以在适配器中使用它，您可以有一个并行数组来将歌曲标题与歌词匹配
但您最好直接使用 SQLite 数据库或使用 Android Rooms 处理此类内容。
房间训练material（SQLite 之上的一层）https://developer.android.com/training/data-storage/room/
或更直接https://developer.android.com/training/data-storage/sqlite.html
List<String> myLyricList = Arrays.asList(getResources().getStringArray(R.array.array_lyrics));
List<String> myTitleList = Arrays.asList(getResources().getStringArray(R.array.array_titles));
strings.xml
<string-array name="array_lyrics">
<item>This song lyrics 1</item>
<item>This song lyrics 2</item>
</string-array>
<string-array name="array_titles">
<item>Song 001</item>
<item>Song 002</item>

这是我保存列表数组的地方MainActivity.java

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
//initialize preferences
PreferenceUtils.initialize(getApplicationContext());
ActionBar actionBar = getSupportActionBar();
actionBar.setTitle("Redeemed Songs");

//let's simply say, the song identifier is just the order of the song in the list
model.id = i;
//bind all strings in an array
arrayList.add(model);
}
//pass result to listview class

您可以从 strings.xml 中的字符串数组创建一个列表，然后可以在适配器中使用它，您可以有一个并行数组来将歌曲标题与歌词匹配
但您最好直接使用 SQLite 数据库或使用 Android Rooms 处理此类内容。
房间训练material（SQLite 之上的一层）https://developer.android.com/training/data-storage/room/
或更直接https://developer.android.com/training/data-storage/sqlite.html
List<String> myLyricList = Arrays.asList(getResources().getStringArray(R.array.array_lyrics));
List<String> myTitleList = Arrays.asList(getResources().getStringArray(R.array.array_titles));
strings.xml
<string-array name="array_lyrics">
<item>This song lyrics 1</item>
<item>This song lyrics 2</item>
</string-array>
<string-array name="array_titles">
<item>Song 001</item>
<item>Song 002</item>
</string-array>
