Im having a problem where the android scrollview starts hiding a pair of textviews I have at the top of my layout, I have found another person on this very site who had that problem and was able to get help unfortunately the person who helped them didnt actually say what fixes it, can anyone tell me what was the fix here?

android scrollview hiding top content

any help would be huge here is my xml code:

<?xml version="1.0" encoding="utf-8"?> <ScrollView xmlns:android="http://schemas.android.com/apk/res/android" xmlns:ads="http://schemas.android.com/apk/lib/com.google.ads" android:layout_width="fill_parent" android:layout_height="fill_parent" android:background="@color/title_color_dark_transparent" > <LinearLayout android:layout_width="fill_parent" android:layout_height="match_parent" android:layout_gravity="center_vertical|center_horizontal|center" android:orientation="vertical" > <LinearLayout android:layout_width="fill_parent" android:layout_height="fill_parent" android:layout_gravity="center" android:layout_marginLeft="8dp" android:layout_marginRight="8dp" android:layout_marginTop="5dp" android:orientation="vertical" android:paddingTop="5dp" > <TextView android:id="@+id/saysomething" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="@string/loading" android:textColor="#FFFFFF" android:textSize="30dp" /> <TextView android:id="@+id/saysomethinginfo" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_marginBottom="5dp" android:text="@string/loading" android:textColor="#FFFFFF" android:textSize="17dp" /> <EditText android:id="@+id/tweetedittext" android:layout_width="fill_parent" android:layout_height="wrap_content" android:background="@drawable/edit_text" android:gravity="top" android:hint="@string/edittext_hint" android:inputType="textCapSentences|textMultiLine|textAutoCorrect|textAutoComplete" android:lines="3" android:textAppearance="@style/TextAppearance.EditText" android:textSize="17dp" /> <RelativeLayout android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_marginBottom="5dp" android:layout_marginTop="5dp" android:orientation="horizontal" > <Button android:id="@+id/photobutton" style="@style/TextAppearance.Button" android:layout_width="wrap_content" android:layout_height="wrap_content" android:background="@drawable/button_background" android:onClick="photobuttonClicked" android:text="@string/photobuttontext" android:textSize="15dp" /> <TextView android:id="@+id/charactersremaining" android:layout_width="wrap_content" android:layout_height="fill_parent" android:layout_centerInParent="true" android:layout_toLeftOf="@+id/posttweetbutton" android:text="@string/characters" android:textColor="#FFFFFF" android:textSize="20dp" /> <Button android:id="@id/posttweetbutton" style="@style/TextAppearance.Button" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentRight="true" android:layout_marginLeft="2dp" android:background="@drawable/button_background" android:onClick="posttweetbuttonClicked" android:text="@string/postbuttonstext" android:textSize="15dp" /> </RelativeLayout> </LinearLayout> <TextView android:id="@+id/photodetails" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="" android:textColor="#FFFFFF" android:textSize="17dp" android:layout_marginTop="8dp" android:layout_marginLeft="8dp" /> <ImageView android:id="@+id/iv_pic" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_marginLeft="8dp" android:layout_marginRight="8dp" /> </LinearLayout> </ScrollView>

    I fail to see any TextViews above your ScrollView. You're also missing your closing tag on your ScrollView. Commented Mar 28, 2012 at 22:14
  • seems like I mistakenly didnt comment in the closing tag for the scrollview but its there now, the textviews are the first ones that you see inside the linear layout, placing the textviews outside the linear layout gives me an error because apparently you cant have more than one child in the scrollview Commented Mar 28, 2012 at 22:19
  • I thought you don't want your ScrollView to hide those TextViews? Maybe you should explain what you actually want the layout to look like, because it's not very clear to me. Commented Mar 28, 2012 at 22:20
  • the layout is too big for the screen, so I put it in a scrollview, but when I set the image in the imageview the 2 textviews "@+id/saysomething" and "@+id/saysomethinginfo" are hidden and cant be scrolled to see what it says, what I need is for the user to be able to scroll up and be able to see whats hidden under there Commented Mar 28, 2012 at 22:28
  • Might this be of help stackoverflow.com/questions/8280051/… Commented Mar 28, 2012 at 22:36

Found it ! It's the android:layout_gravity="center" in the LinearLayout that is the culprit. Just delete this and everything should be fine.

Thanks for this - worked for me in an instance of this problem.
Works, and if you still need to center the View inside use this workaround: pivotallabs.com/centering-a-view-within-a-scrollview
Big thank you @Sylphe, strange that your answer not accepted :(
Many thanks for this. I had a similar problem but in a HorizontalScrollView. Shouldn't this be filed as a bug on Google Code? At the very least, lint should be added to warn of this perhaps.
removing 'android:layout_gravity="center"' is helped for me! Thanks guy! :))))))))))))

Have you tried setting

android:fillViewport="true"

in the ScrollView?

<ScrollView xmlns:android="http://schemas.android.com/apk/res/android" xmlns:ads="http://schemas.android.com/apk/lib/com.google.ads" android:layout_width="fill_parent" android:layout_height="fill_parent" android:fillViewport="true" android:background="@color/title_color_dark_transparent" >

You can scroll programmatically.

  1. Remove android:layout_gravity property from xml
  2. Add scrolling to onResume function

Some code from my project:

protected void onResume() { super.onResume(); final HorizontalScrollView svInMenu = (HorizontalScrollView) findViewById(R.id.svInMenu); ViewTreeObserver vto = svInMenu.getViewTreeObserver(); vto.addOnGlobalLayoutListener(new OnGlobalLayoutListener() { public void onGlobalLayout() { svInMenu.scrollTo(svInMenu.getRight() / 4, 0); } }); }

Your outer LinearLayout has its height set to match_parent. It should be wrap_content instead. The inner LinearLayout should also have height wrap_content.

Add android:layout_weight="1" to your scrollview. It will resolve the problem. Something like this

 <ScrollView android:id="@+id/scroll" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_weight="1" >
