如何使用 android 中的意圖打開存儲中的特定文件夾

Question

我已經嘗試了很多與這個問題相關的答案，但沒有一個有效。 這是我的代碼，但它沒有打開 myFile 文件夾。 請幫我解決這個問題

val intent = Intent(Intent.ACTION_GET_CONTENT)
      val uri = Uri.parse(
            (Environment.getExternalStorageDirectory().absolutePath) + "/myFile/")
      intent.setDataAndType(uri, "*/*")
      startActivityForResult(intent, WRITE_ACCESS_CODE)

Answer 1

試試這個 -->

  Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
Uri uri = Uri.parse(Environment.getExternalStorageDirectory().getPath()
     +  File.separator + "myFolder" + File.separator);
intent.setDataAndType(uri, "text/csv");
startActivity(Intent.createChooser(intent, "Open folder"));

或者

// location = "/sdcard/my_folder";
Intent intent = new Intent(Intent.ACTION_VIEW);
Uri mydir = Uri.parse("file://"+location);
intent.setDataAndType(mydir,"application/*");    // or use */*
startActivity(intent);

Answer 2

此代碼可以幫助您：

Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.setType("file/*");
startActivityForResult(intent, YOUR_RESULT_CODE);

如果要打開特定文件夾：

Intent intent = new Intent(Intent.ACTION_GET_CONTENT);

intent.setDataAndType(Uri.parse(Environment.getExternalStorageDirectory().getPath()
 +  File.separator + "myFolder" + File.separator), "file/*");
startActivityForResult(intent, YOUR_RESULT_CODE);

Answer 3

如果您使用Kotlin ，請查看此方式：

val intent = Intent(Intent.ACTION_GET_CONTENT)
intent.setDataAndType(data?.toUri(), "application/vnd.ms-excel") // or application/*
startActivity(Intent.createChooser(intent, "Open folder"))

其中數據是您的文件的位置。

if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.Q)
    {
        StorageManager sm = (StorageManager) context.getSystemService(Context.STORAGE_SERVICE);

        Intent intent = sm.getPrimaryStorageVolume().createOpenDocumentTreeIntent();
        //String startDir = "Android";
        //String startDir = "Download"; // Not choosable on an Android 11 device
        //String startDir = "DCIM";
        //String startDir = "DCIM/Camera";  // replace "/", "%2F"
        //String startDir = "DCIM%2FCamera";
        String startDir = "Documents";

        Uri uri = intent.getParcelableExtra("android.provider.extra.INITIAL_URI");

        String scheme = uri.toString();

        Log.d(TAG, "INITIAL_URI scheme: " + scheme);

        scheme = scheme.replace("/root/", "/document/");

        scheme += "%3A" + startDir;

        uri = Uri.parse(scheme);

        intent.putExtra("android.provider.extra.INITIAL_URI", uri);

        Log.d(TAG, "uri: " + uri.toString());

        ((Activity) context).startActivityForResult(intent, REQUEST_ACTION_OPEN_DOCUMENT_TREE);

    }
