Question

I have one main Activity with layout wrapped into ScrollView like this:

<ScrollView android:layout_height="wrap_content" android:layout_width="fill_parent" android:layout_weight="1">

User can scroll up and down and there is some buttons when user scrolls down.

When user presses a button – I run code like this:

public void onClick(View view)
        {
            Log.d(LOG_TAG, "onClick");

            TireView tiat = (TireView)view;

            Intent i = new Intent(TrailerInspectionActivity.this, TireInspectionActivity.class);
            i.putExtra(TireInspectionActivity.INTENT_TIRE_NUMBER, tiat.getNumber());
            if (tiat.getDepth() != -1)
            {
                i.putExtra(TireInspectionActivity.INTENT_DEPTH, tiat.getDepth());
                i.putExtra(TireInspectionActivity.INTENT_PRESSURE, tiat.getPressure());
            }

            TrailerInspectionActivity.this.startActivityForResult(i, REQUEST_CODE_TIRE_INSPECTION_ACTIVITY);
        }

TireInspectinActivity starts and shows like popup – I use theme.Dialog for that.

As soon as user clicks and popups show up – main activity ScrollView scrolls all way up.
Is there any way to prevent this from happening?

Answer 1

You should record the current position of your ScrollView (getScrollY) and restore that in onResume for your activity.
