Automatically go to furthest right (last horizontal child) then back to furthest left(first child) in a horizontal scroll view

I have cards in a horizontal LinearLayout which is then in a HorizontalScrollView that I would like to rotate about left to right and back like an image slideshow.
Here is my XML, it contains 5 cards which are in horizontal alignment

I have tried using tags such as <ViewFlipper with that users cannot scroll themselves within the layout.

Use a timer for continuous scrolling, and using canScrollHorizontally() to check wether it reached the furthest right then start scrolling left,
canScrollHorizontally() takes positive int for right direction, negative int for left direction
private HorizontalScrollView scrollView;
private boolean scrollingLeft;
int pace = 50;
private Timer timer;
timer = new Timer("horizontalScrollViewTimer");
timer.scheduleAtFixedRate(new TimerTask() {
#Override
public void run() {
runOnUiThread(new Runnable() {
#Override
public void run() {
if (scrollView.canScrollHorizontally(1)&&!scrollingLeft ) {
Log.d(TAG, "Scrolling right");
scrollView.smoothScrollBy(pace, 0);
}
else {
Log.d(TAG, "Scrolling left");
scrollingLeft =true;
scrollView.smoothScrollBy(-pace, 0);
if(!scrollView.canScrollHorizontally(-1)) // reached the furthest left turn of scrolling left
scrollingLeft = false;
}
}
});
}
}, 3000, 50);

Move the scrolled position of your view.

Parameters

You can try like this codes. Such as

I expect it will be helpful for you. Best of luck!

Try adding views dynamically in linear layout which is inside scroll view.
Try this code.I know it is not exact solution.But,Hope it gives you some idea.
public class MainActivity extends Activity {
ScrollView scrollview;
LinearLayout linearLayout;
LinearLayout.LayoutParams layoutParams;
static int i;
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
scrollview = (ScrollView)findViewById(R.id.scrollview);
linearLayout = (LinearLayout)findViewById(R.id.linearlayout);
Button button = (Button)findViewById(R.id.button);
layoutParams = new LinearLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
button.setOnClickListener(new OnClickListener(){
public void onClick(View v) {
TextView view = new TextView(MainActivity.this);
view.setText(++i+" view");
linearLayout.addView(view, layoutParams);
}
});
}}

first inf_child.xml layout:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<LinearLayout
android:id="#+id/inf_dynamicLl"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >
</LinearLayout>
<LinearLayout
android:id="#+id/btnContainer"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal" >
<Button
android:layout_height="wrap_content"
android:layout_width="0dp"
android:layout_weight="0.25"
android:text="OK"/>
<Button
android:layout_height="wrap_content"
android:layout_width="0dp"
android:layout_weight="0.25"
android:text="Cancel"/>
</LinearLayout>
</LinearLayout>
second inf_dynamic_view.xml layout which will generate row dynamically:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/inner_linear_layout"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
>
<TextView
android:id="#+id/firstText"
android:layout_width="0dp"
android:layout_weight="0.25"
android:layout_height="wrap_content"
/>
<TextView
android:id="#+id/secontText"
android:layout_width="0dp"
android:layout_weight="0.25"
android:layout_height="wrap_content"
/>
<TextView
android:id="#+id/ThirdText"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="0.25" />
<EditText
android:id="#+id/editText"
android:layout_height="wrap_content"
android:layout_width="0dp"
android:layout_weight="0.25"
/>
</LinearLayout>
if (convertView == null) {
LayoutInflater infalInflater = (LayoutInflater) mContext.getSystemService(mContext.LAYOUT_INFLATER_SERVICE);
convertView = infalInflater.inflate(R.layout.inf_child, null);
}
LinearLayout dynamicLl = (LinearLayout) convertView.findViewById(R.id.inf_dynamicLl);
for (int rowCounter = 0; rowCounter < parentData.get(groupPosition).childData.get(childPosition).price.size(); rowCounter++)
createRow(dynamicLl, parentData.get(groupPosition).childData.get(childPosition).price.get(rowCounter), groupPosition);
=> create row dynamically
private void createRow(LinearLayout lView, String price, int childPosition) {
LayoutInflater vi = (LayoutInflater) mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View l = vi.inflate(R.layout.inf_dynamic_view, null);
final TextView tvFirst, tvSecond,tvThird;
final EditText edt1;
lView.addView(l);
lView.refreshDrawableState();
}
