Why does my android activity always start scrolled to the bottom?

Android Problem Overview

Whenever I start this activity, it always starts bottomed out--scrolled all the way to the bottom. I am not doing anything weird in the activity OnCreate (or anywhere for that matter) that I would expect to change the scroll position. I have tried setting focus to the topmost focusable control, and the scrollto method, but neither of them are working. Besides, none of my other activities has this problem. Here's the layout:

<ScrollView
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/scroll"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content">

        <TextView

Android Solutions

Solution 1 - Android

When Android starts an activity, some control needs to take focus. When there's no designated control to take focus, the system chooses the first eligible control that wants focus. If you set the following property in your LinearLayout - android:focusableInTouchMode="true" your LinearLayout will be focused on start and your activity won't scroll to EditText in the bottom.

Solution 2 - Android

Instead of polluting items in your layout, you can add this into your Activity/Class:

    ScrollView scrollView = (ScrollView) findViewById(R.id.scrollView);
    scrollView.setFocusableInTouchMode(true); 
    scrollView.setDescendantFocusability(ViewGroup.FOCUS_BEFORE_DESCENDANTS);

This way it isn't an element within your scrollView getting focus, it's your scrollView as a container which get's the first focus, moving onto the child view's after this.

Solution 3 - Android

You can try this code:

scroller.post(new Runnable() { 
    public void run() { 
        scroller.fullScroll(ScrollView.FOCUS_DOWN); 
    } 
});

Solution 4 - Android

Add these two lines in your ScrollView

 android:focusableInTouchMode="true"
 android:descendantFocusability="blocksDescendants"

Solution 5 - Android

Along with what devmiles.com said.

> If you set the following property in your LinearLayout - android:focusableInTouchMode="true" your LinearLayout will be focused on start and your activity won't scroll to EditText in the bottom.

If you call requestLayout() on a view at the bottom of your linear layout it might steal the focus from your top most view. So just call requestFocus() on the top most view in the linear layout after calling requestLayout() on a lower view.

Solution 6 - Android

I don't know why but you could experiment with

ScrollView sv = (ScrollView) findViewById(R.id.scroll);
sv.scrollTo(0,0);

in your onCreate to manually scroll it to where you like it to be.

Solution 7 - Android

Have you tried use fullScroll method ?http://developer.android.com/reference/android/widget/ScrollView.html#fullScroll(int)

yourScrollView.fullScroll(ScrollView.FOCUS_UP);

Solution 8 - Android

For Xamarin Android development, if you want to do @Graeme solution then:

// Set Focus to ScrollView
ScrollView scrollView = (ScrollView)FindViewById(Resource.Id.scrollView);
scrollView.FocusableInTouchMode = true;
scrollView.DescendantFocusability = Android.Views.DescendantFocusability.BeforeDescendants;

Solution 9 - Android

Just make it not focusable in onCreate()

editText.setFocusable(false);

and use

editText.setOnClickListener(new ....){
 ......
  editText.setFocusable(true);
  editText.setFocusableInTouchMode(true);
  editText.requestFocus();

  showSoftKeyboard(); //Use InputMethodManager to open soft Keyboard

 ......
 };

and it will not scroll down to Edittext next time, a fragment or activity is created.

Solution 10 - Android

scrollView.requestFocus(View.FOCUS_UP) solved my problem when I wanted the top view to be visible. Specifying direction parameter to the method requestFocus(int direction) is a good way to control the ScrollView position. More details here.

Solution 11 - Android

In my case I had a VideoView inside a ConstraintLayout inside a ScrollView. The VideoView was always stealing focus, and there are issues with it. Solution is to use a TextureView. Hopefully this helps someone, it cost me an hour at least :)

Solution 12 - Android

with Kotlin and ViewBinding u can add this in your fragment or activity :

binding.mainScroll.isFocusableInTouchMode = true
binding.mainScroll.descendantFocusability = ViewGroup.FOCUS_BEFORE_DESCENDANTS
