如何在通过文件浏览器选择文件后在onActivityResult()中使用getContentResolver().query()获取文件路径

Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.setType("*/*");  // 设置文件类型为任意类型
intent.addCategory(Intent.CATEGORY_OPENABLE);  // 设置可打开的文件
startActivityForResult(intent, REQUEST_CODE_FILE_CHOOSER);

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    
    if (requestCode == REQUEST_CODE_FILE_CHOOSER && resultCode == RESULT_OK) {
        Uri fileUri = data.getData();
        String filePath = getFileFromUri(fileUri);
        
        // 使用filePath进行后续操作
    }
}

private String getFileFromUri(Uri uri) {
    String filePath = null;
    String[] projection = {MediaStore.Images.Media.DATA};
    Cursor cursor = getContentResolver().query(uri, projection, null, null, null);
    
    if (cursor != null && cursor.moveToFirst()) {
        int columnIndex = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
        filePath = cursor.getString(columnIndex);
        cursor.close();
    }
    
    return filePath;
}
