java - 如何按字母顺序显示不带扩展名的文件名

Question

我有这个脚本，它允许在 ListView 中显示位于特定文件夹中的文件的名称。

我想知道是否可以调整此脚本以显示不带扩展名并按字母顺序排列的文件。谢谢

    File dir = new File(Environment.getExternalStorageDirectory().getPath() + "/osmdroid/tiles/");
    File[] filelist = dir.listFiles();
    String[] theNamesOfFiles = new String[filelist.length];
    for (int i = 0; i < theNamesOfFiles.length; i++) {
       theNamesOfFiles[i] = filelist[i].getName();
    }

    adapter = new ArrayAdapter<String>(this, R.layout.list_row, theNamesOfFiles);
    lv.setAdapter(adapter);

Answer 1

试试这个

File dir = new File(Environment.getExternalStorageDirectory().getPath() + "/osmdroid/tiles/");
File[] filelist = dir.listFiles();
String[] theNamesOfFiles = new String[filelist.length];
for (int i = 0; i < theNamesOfFiles.length; i++) {
   //do a little change
   String temp = filelist[i].getName();
   theNamesOfFiles[i] = temp.substring(0,temp.length() - temp.lastIndexOf("."));
}
Arrays.sort(theNamesOfFiles)
adapter = new ArrayAdapter<String>(this, R.layout.list_row, theNamesOfFiles);
lv.setAdapter(adapter);
