Android Horizontal scrolling image gallery

Question

I'd like to create app with horizontal image gallery (with one row and multiple columns). First i try to use gridview, but it can be used as vertical scroll only. Can i use ListView or GridView for that purposes?

Answer 1

create LinearLayout inside HorizontalScrollView,then create an imageView dynamically and add that imageview to linearLayout.

Example code:

<HorizontalScrollView 
android:id="@+id/horizontal_scroll"
android:layout_width="match_parent"
android:layout_height="wrap_content" >

    <LinearLayout
    android:id="@+id/linear"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:orientation="horizontal" >
    </LinearLayout>

</HorizontalScrollView>

In onCreate() method,get the id of linearLayout from the xml file and add dynamically created ImageView to linearlayout:

    LinearLayout layout = (LinearLayout) findViewById(R.id.linear);
    for (int i = 0; i < 10; i++) {
        ImageView imageView = new ImageView(this);
        imageView.setId(i);
        imageView.setPadding(2, 2, 2, 2);
        imageView.setImageBitmap(BitmapFactory.decodeResource(
                getResources(), R.drawable.ic_launcher));
        imageView.setScaleType(ScaleType.FIT_XY);
        layout.addView(imageView);
    }

See a working demo from here

With the release of RecyclerView library, you can easily implement both horizontal and vertical list orientation. This is made possible by use of the LinearLayoutManager for which you can specify the orientation either horizontal or vertical as shown below ...

 LinearLayoutManager horizontalLayoutManager = new LinearLayoutManager(MainActivity.this, LinearLayoutManager.HORIZONTAL, false);
