Why it is not opening defined folder via intent in Android?

问题

This code is redirecting to drive with open navigation but not opening actual given path

OLD Code

Uri uri = Uri.parse(Environment.getExternalStorageDirectory().getPath() + "/foldername/");
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.addCategory(Intent.CATEGORY_OPENABLE);
intent.setDataAndType(uri, "text/csv");
startActivity(intent);

The path value I am getting through uri is:
/storage/emulated/0/myfolder

NEW Code

Intent resultIntent = new Intent(Intent.ACTION_OPEN_DOCUMENT);
resultIntent.addCategory(Intent.CATEGORY_OPENABLE);
Uri uri = 
Uri.parse(Environment.getExternalStorageDirectory().getPath() + 
"/myfolder/");
resultIntent.setType("*/*");
resultIntent.putExtra("android.provider.extra.INITIAL_URI", uri);
// show the entire internal storage tree
//resultIntent.putExtra("android.content.extra.SHOW_ADVANCED", true);
startActivity(resultIntent);

Let me know the issue where is the problem in this code.

回答1:

private static final int READ_REQUEST_CODE = 10;
...
/**
 * Fires an intent to spin up the "file chooser" UI and select an image.
 */
public void performFileSearch() {

    Intent intent = new Intent(Intent.ACTION_OPEN_DOCUMENT);
    intent.addCategory(Intent.CATEGORY_OPENABLE);
    intent.setType(uri, "text/*");

    startActivityForResult(intent, READ_REQUEST_CODE);
}

After the user selects a document in the picker, onActivityResult() gets called. The resultData parameter contains the URI that points to the selected document. Extract the URI using getData(). When you have it, you can use it to retrieve the document the user wants.

@Override
public void onActivityResult(int requestCode, int resultCode,
        Intent resultData) {

    if (requestCode == READ_REQUEST_CODE && resultCode == Activity.RESULT_OK) {

        Uri uri = null;
        if (resultData != null) {
            uri = resultData.getData();
            Log.i(TAG, "Uri: " + uri.toString());
            showImage(uri);
        }
    }
}
