如何使android listview适配器位置匹配

如何解决如何使android listview适配器位置匹配

我创建了一个文件管理器，可以浏览存储在此设备上的文件和文件夹。

我为listView创建了一个自定义适配器，以使其显示更多详细信息，并使用以下代码。

private static final class FileAdaptor extends BaseAdapter {
        private final String directory;
        private final AppCompatActivity activity;
        private final File[] files;

        FileAdaptor(AppCompatActivity activity,String directory) {
            this.directory = directory;
            this.activity = activity;
            files = getDirectoryInfo();
        }

        private File[] getDirectoryInfo() {
            assert directory != null;
            File a = new File(directory);
            if (!a.exists()) throw new RuntimeException("File" + a.getName() + "does not exists");
            else {
                File[] b = a.listFiles();
                /*if (b != null)
                    Arrays.sort(b);*/
                return b;
            }
        }

        @Override
        public final int getCount() {
            return files.length;
        }

        @Override
        public final Object getItem(int position) {
            return null;
        }

        @Override
        public final long getItemId(int position) {
            return 0;
        }

        public final String getFileName(int position) {
            return files[position].getName();
        }

        public final String getFileModifiedData(int position) {
            return new SimpleDateFormat("MM/dd/yyyy HH:mm:ss").format(files[position].lastModified());
        }

        public final File[] getFiles() {
            return files;
        }

        @Override
        public final View getView(int position,View convertView,ViewGroup parent) {
            if (convertView == null)
                convertView = activity.getLayoutInflater().inflate(R.layout.file_manager_items,parent,false);
            AppCompatImageView a = activity.findViewById(R.id.itemIcon);
            AppCompatTextView b = activity.findViewById(R.id.fileName);
            AppCompatTextView c = activity.findViewById(R.id.fileInfo);
            File f = files[position];
            String s = getFileName(position);
            try {
                if (f.isDirectory())
                    a.setImageDrawable(ContextCompat.getDrawable(activity,R.drawable.folder));
                else {
                    if (isImageFile(s))
                        try {
                            Bitmap e = BitmapFactory.decodeFile(f.getAbsolutePath());
                            a.setImageBitmap(e);
                        } catch (Exception e) {
                            e.printStackTrace();
                            a.setImageDrawable(ContextCompat.getDrawable(activity,R.drawable.image_file));
                        }
                    else if (isMusicFile(s))
                        a.setImageDrawable(ContextCompat.getDrawable(activity,R.drawable.music_file));
                    else if (isTextFile(s))
                        a.setImageDrawable(ContextCompat.getDrawable(activity,R.drawable.text_document));
                    else if (isCodeFile(s))
                        a.setImageDrawable(ContextCompat.getDrawable(activity,R.drawable.code_file));
                    else if (isZipFile(s))
                        a.setImageDrawable(ContextCompat.getDrawable(activity,R.drawable.zip_file));
                    else if (isApkFile(s))
                        try {
                            a.setImageDrawable(Objects.requireNonNull(activity.getPackageManager().getPackageArchiveInfo(f.getAbsolutePath(),0)).applicationInfo.loadIcon(activity.getPackageManager()));
                        } catch (Exception e) {
                            e.printStackTrace();
                            a.setImageDrawable(ContextCompat.getDrawable(activity,R.drawable.apk_file));
                        }
                    else if (isXApkFile(s))
                        a.setImageDrawable(ContextCompat.getDrawable(activity,R.drawable.apk_file));
                    else
                        a.setImageDrawable(ContextCompat.getDrawable(activity,R.drawable.file));
                }
                b.setText(s);
                c.setText(getFileModifiedData(position));
            } catch (Throwable e) {
                e.printStackTrace();
            }
            return convertView;
        }

        private boolean isImageFile(String a) {
            return a.contains(".png") || a.contains(".jpg") || a.contains(".jpeg") || a.contains(".bmp") || a.contains(".gif") || a.contains(".webp") || a.contains(".tiff") || a.contains(".tif");
        }

        private boolean isMusicFile(String a) {
            return a.contains(".mp3") || a.contains(".flac") || a.contains(".aac") || a.contains(".wav") || a.contains(".m4a") || a.contains(".wma") || a.contains(".ogg") || a.contains(".mid");
        }

        private boolean isTextFile(String a) {
            return a.contains(".txt") || a.contains(".properties") || a.contains(".ini");
        }

        private boolean isCodeFile(String a) {
            return a.contains(".java") || a.contains(".cpp") || a.contains(".c") || a.contains(".h") || a.contains(".lua") || a.contains(".cs") || a.contains(".xml") || a.contains(".css") || a.contains(".kt") || a.contains(".js") || a.contains(".json");
        }

        private boolean isZipFile(String a) {
            return a.contains(".zip");
        }

        private boolean isApkFile(String a) {
            return a.contains(".apk");
        }

        private boolean isXApkFile(String a) {
            return a.contains(".xapk") || a.contains(".apks");
        }
    }

但是，当我尝试在单击侦听器上为列表视图创建项目时，如下所示：

listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> parent,View view,int position,long id) {
                try {
                    previousDirectory.add(currentFile);
                    currentFile = adaptor.getFiles()[position].getAbsolutePath();
                    refreshContent();
                } catch (Exception e) {
                    e.printStackTrace();
                    Toast.makeText(view.getContext(),e.toString(),Toast.LENGTH_LONG).show();
                }
            }
        });

点击监听器上的位置与适配器中的实际位置不匹配。（当我单击一个文件夹时，它将带我到另一个文件夹）每个人都可以帮助我解决这个问题

还有另一个问题是对文件列表进行排序。我已经尝试过Arrays.sort（fileList）;，但是它不会像常规文件管理器一样将文件夹排序在一起并遵循字母顺序。每个人都可以解决这个问题吗
