Android: Let user pick image or video from Gallery

问题:

Is it possible to to start Gallery in such a way so both pictures and videos are shown?

Thanks

回答1:

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.

回答7:

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/*");

回答8:

No, it's not possible with the stock Gallery app. You can try and search for an app that does this.
