Android: Let user pick image or video from Gallery

Is it poss开发者_如何学Pythonible to to start Gallery in such a way so both pictures and videos are shown?

Thanks

Pick Audio file from Gallery:

//Use MediaStore.Audio.Media.EXTERNAL_CONTENT_URI
Intent intent = new Intent(Intent.ACTION_PICK, MediaStore.Audio.Media.EXTERNAL_CONTENT_URI);

Pick Video file from Gallery:

//Use MediaStore.Audio.Media.EXTERNAL_CONTENT_URI
Intent intent = new Intent(Intent.ACTION_PICK, MediaStore.Video.Media.EXTERNAL_CONTENT_URI);

Pick Image from gallery:

//Use  MediaStore.Images.Media.EXTERNAL_CONTENT_URI
Intent intent = new Intent(Intent.ACTION_PICK, MediaStore.Images.Media.EXTERNAL_CONTENT_URI);

Pick Media Files or images:

 Intent intent = new Intent(Intent.ACTION_PICK, MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
intent.setType("image/* video/*");

You start the gallery as such:

Intent pickIntent = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
pickIntent.setType("image/* video/*");
startActivityForResult(pickIntent, IMAGE_PICKER_SELECT);

then in your onActivityResult you can check if video or image was selected by doing this:

public void onActivityResult(int requestCode, int resultCode, Intent data) {

if (resultCode == RESULT_OK) {
    Uri selectedMediaUri = data.getData();
    if (selectedMediaUri.toString().contains("image")) {
        //handle image
    } else  if (selectedMediaUri.toString().contains("video")) {
        //handle video
    }
}

(EDIT: I don't use it anymore, we went back to the two choices "pick image" and "pick video". The problem was with some Sony phone. So, it's not 100% solution below, be careful! )

This is what I use:

if (Build.VERSION.SDK_INT < 19) {
    Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
    intent.setType("image/* video/*");
    startActivityForResult(Intent.createChooser(intent, getResources().getString(R.string.select_picture)), SELECT_GALLERY);
} else {
    Intent intent = new Intent(Intent.ACTION_OPEN_DOCUMENT);
    intent.addCategory(Intent.CATEGORY_OPENABLE);
    intent.setType("image/*");
    intent.putExtra(Intent.EXTRA_MIME_TYPES, new String[] {"image/*", "video/*"});
    startActivityForResult(intent, SELECT_GALLERY_KITKAT);
}

The key here is intent.putExtra(Intent.EXTRA_MIME_TYPES, new String[] {"image/*", "video/*"});

intent.setType("*/*");

This presents user with dialog but works on at least ICS. Haven't tested on other platforms.

When you need to determine what kind of content was returned, you can do it using content resolver to get the MIME type of the returned content:

if( data != null) {
    Uri selectedUri = data.getData();   
    String[] columns = { MediaStore.Images.Media.DATA,
                         MediaStore.Images.Media.MIME_TYPE };

    Cursor cursor = getContentResolver().query(selectedUri, columns, null, null, null);
    cursor.moveToFirst();

    int pathColumnIndex     = cursor.getColumnIndex( columns[0] );
    int mimeTypeColumnIndex = cursor.getColumnIndex( columns[1] );

    String contentPath = cursor.getString(pathColumnIndex);
    String mimeType    = cursor.getString(mimeTypeColumnIndex);
    cursor.close();

    if(mimeType.startsWith("image")) {
          //It's an image
    }
    else if(mimeType.startsWith("video")) {
         //It's a video
    }       
}
else {
    // show error or do nothing
}

CoolIris which came with my galaxy tab can do it. However the cooliris on my acer betouch will not :S On my milestone you can not start the gallery with a pick intent on the video url however when you start it on the images url, you can select a video and it will return a video url too.

UPDATE 2021

FINALLY a solution working for Android 9.

This piece of code only open image apps, and you can select both images and videos. I tried a bunch of different combinations and this exact code will make it work.

    libraryIntent.setType("video/*, image/*");
    String[] mimetypes = {"image/*", "video/*"};
    libraryIntent.putExtra(Intent.EXTRA_MIME_TYPES, mimetypes);

Still Working On Jan'2022

If This is Working For You Then Try it,

Intent intent = new Intent(Intent.ACTION_PICK, android.provider
                          .MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
    intent.setType("image/* video/*");
    startActivityForResult(intent,PICK_FILE);

else For Older SDK's and For Some Devices Try the below one,

 Intent intent = new Intent(Intent.ACTION_OPEN_DOCUMENT);
    intent.addCategory(Intent.CATEGORY_OPENABLE);
    intent.setType("image/*");
    intent.putExtra(Intent.EXTRA_MIME_TYPES, new String[] {"image/*", "video/*"});
     startActivityForResult(intent,PICK_FILE);

where, PICK_FILE is a variable,

private static final int PICK_FILE = 1;

This is working for me for Android 12 (SDK 32)
Pick multiple images & videos from the gallery
Also with the latest registerForActivityResult

val resultLauncher =
        registerForActivityResult(ActivityResultContracts.StartActivityForResult()) { result ->
            onActivityResult(result)
        }

fun pickMediaFiles() {
        val intent = Intent(Intent.ACTION_GET_CONTENT)
        intent.addCategory(Intent.CATEGORY_OPENABLE)
        intent.type = "image/* video/*"
        intent.putExtra(Intent.EXTRA_ALLOW_MULTIPLE, true);
        intent.putExtra(Intent.EXTRA_MIME_TYPES, arrayOf("image/*", "video/*"))
        resultLauncher.launch(intent)
    }

fun onActivityResult(result: ActivityResult) {
        if (result.resultCode == RESULT_OK && result.data != null) {
            //If selected multiple medias
            if (result.data?.clipData != null) {
                val count: Int =
                    result.data!!.clipData!!.itemCount 
                for (i in 0 until count) {
                    val selectedUri: Uri? = result.data!!.clipData?.getItemAt(i)?.uri
                }
            }
            //If selected single media
            else if (result.data?.data != null) {
                val selectedUri: Uri? = result.data?.data
            }
        }
    }

You need use the following as picking Intent

Intent photoLibraryIntent = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
photoLibraryIntent.setType("image/* video/*");
