如何在Android的listview中显示存储中的doc、docx、pdf、xls、txt

<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />

<ListView
    android:id="@+id/listView"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

ListView listView = findViewById(R.id.listView);

// 获取存储中的文件列表
List<File> fileList = getFileListFromStorage();

// 创建适配器
ArrayAdapter<String> adapter = new ArrayAdapter<>(this,
    android.R.layout.simple_list_item_1, getFileNames(fileList));

// 将适配器关联到ListView
listView.setAdapter(adapter);

private List<File> getFileListFromStorage() {
    List<File> fileList = new ArrayList<>();
    File storageDir = Environment.getExternalStorageDirectory();

    File[] files = storageDir.listFiles();
    if (files != null) {
        for (File file : files) {
            if (isSupportedFile(file)) {
                fileList.add(file);
            }
        }
    }

    return fileList;
}

private boolean isSupportedFile(File file) {
    String fileName = file.getName();
    return fileName.endsWith(".doc") || fileName.endsWith(".docx") ||
           fileName.endsWith(".pdf") || fileName.endsWith(".xls") ||
           fileName.endsWith(".txt");
}

private List<String> getFileNames(List<File> fileList) {
    List<String> fileNames = new ArrayList<>();
    for (File file : fileList) {
        fileNames.add(file.getName());
    }
    return fileNames;
}

listView.setOnItemClickListener((parent, view, position, id) -> {
    File selectedFile = fileList.get(position);

    Intent intent = new Intent(Intent.ACTION_VIEW);
    intent.setDataAndType(Uri.fromFile(selectedFile), getMimeType(selectedFile));
    intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);

    try {
        startActivity(intent);
    } catch (ActivityNotFoundException e) {
        Toast.makeText(getApplicationContext(),
            "No application found to open this file.", Toast.LENGTH_SHORT).show();
    }
});

private String getMimeType(File file) {
    String extension = MimeTypeMap.getFileExtensionFromUrl(file.getAbsolutePath());
    return MimeTypeMap.getSingleton().getMimeTypeFromExtension(extension);
}
