I'm trying to make a screen scrollable with scroll view but my application keeps crashing.
What I've done is to replace RelativeLayout by ScrollView, but it doesn't work.
I need your help with this. Here is the code of the screen:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
android:paddingBottom="0dp"
android:background="#drawable/background01"
tools:context=".MainActivity"
android:id="#+id/relativeLayout">
<LinearLayout
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:id="#+id/id"
android:background="#drawable/lightcontainer"
android:layout_alignParentBottom="true"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"
android:weightSum="1"
android:paddingLeft="20dp"
android:paddingRight="20dp"
android:layout_marginBottom="16dp">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/mainTitle1"
android:id="#+id/textView"
android:layout_gravity="center_horizontal"
android:layout_marginTop="20dp"
android:textSize="20sp"
android:textColor="#ffffff"
android:shadowColor="#000000"
android:shadowRadius="1.5"
android:shadowDx="2"
android:shadowDy="2"/>
</LinearLayout>
what you are trying to do is not an scrollable view it's just a relative layout. Try to put your code inside a ScrollView component, like this:
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/scrollView"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fillViewport="true">
<!-- PUT YOUR CODE HERE -->
</ScrollView>
Make sure you close all tags correctly as well (your relative layout is not closed).
<RelativeLayout>
Content
</RelativeLayout> <-- This closing tag is always necessary

I am creating an Android app which has a main RelativeLayout and some LinearLayout within it.
Now i have this problem. When dragging items to the editor, e.g. a LinearLayout, it doesn't fit to the full width of the screen. How can I make this possible? This is my XML:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:fillViewport="true"
android:gravity="fill"
android:paddingBottom="#dimen/activity_vertical_margin"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
tools:context=".MainActivity" >
<LinearLayout
android:id="#+id/itemDetailLayout"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentRight="true"
android:layout_alignParentTop="true"
android:orientation="vertical"
android:fillViewport="true" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal" >
<ImageView
android:id="#+id/itemImage"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:minHeight="40dp"
android:minWidth="40dp"
android:src="#drawable/ic_launcher" />
<TextView
android:id="#+id/itemName"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="20dp"
android:text="Name"
android:textAppearance="?android:attr/textAppearanceMedium" />
</LinearLayout>
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:orientation="vertical"
android:fillViewport="true" >
<TextView
android:id="#+id/itemRecentHigh"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Recent High" />
<TextView
android:id="#+id/itemRecentLow"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Recent Low" />
<TextView
android:id="#+id/itemAverage"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Average" />
</LinearLayout>
</LinearLayout>
<LinearLayout
android:id="#+id/listViewLayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_below="#+id/itemDetailLayout"
android:layout_marginTop="10dp"
android:fillViewport="true"
android:gravity="fill_horizontal"
android:orientation="vertical" >
<ListView
android:id="#+id/searchListView"
android:layout_width="match_parent"
android:layout_height="fill_parent"
android:fillViewport="true" >
</ListView>
</LinearLayout>
Added a screenshot for more info. Added blue background to have some contrast.
Replace this:
android:layout_width="wrap_content"
android:layout_height="wrap_content"
With
android:layout_width="match_parent"
android:layout_height="wrap_content"
into your LinearLayout or Remove all the Padding from main RelativeLayout
Removing padding makes the linear layout fit the entire screen of the device
The space between the blue part and the "end of the screen". On the sides and above the part where the back button and home button are.
Remove the padding from the root RelativeLayout.
Try
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical>
// Other views within the linear layout
</LinearLayout>
I suppose you are using Eclipse. Personally, I hate the Graphical Editor of Eclipse and I usually write the XML code directly because working with the editor is a real pain
Don't use fill_parent as it is deprecated.
Instead to your RelativeLayout set
android:layout_width="fill_parent"
android:layout_height="fill_parent"
Then, to the list view that you want to fill the rest of the screen, you can set this tags
android:layout_width="fill_parent"
android:layout_height="0dp"
android:layout_weight="1"
By doing so, you are telling the XML that you want your ListView to do what fill_parent used to do in previous versions of Android.
Kind regards!
you should try something like the following :
<LinearLayout
android:id="#+id/itemDetailLayout"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
>
...
</LinearLayout>
what i mean you should do this :
android:layout_width="fill_parent"
for every LinearLayout that you want its width to fill_parent .
FILL_PARENT means that the view wants to be as big as its parent as mentioned in the documentation .
and please give me some feedback
Hope That Helps .

Sorry for dumping my codes here as I can't figure out any other way for you guys to understand my code.
Please help
Inside LinearLayout usually all children have even dimension according to orientation. However, when you would like one child to take a little amount of place and another to fill the rest, you might be interested in layout_weight parameter. If the child that should fill the space gets android:layout_weight="1" it will fill the space making a place for other views.
In order to see the buttons add android:layout_weight="1" to SwipeRefreshLayout and set android:layout_height="0dp". That will make your buttons visible.
I want to have a static imageView inside a ScrollView. I need this image to stay in the same screen position even if the user scrolls. The problem is that the ScrollView accepts only one child element.
<ScrollView
android:id="#+id/scrollView"
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="#dimen/activity_vertical_margin"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
tools:context=".MainActivity">
<ListView
android:id="#+id/finishedGameListView"
android:layout_width="wrap_content"
android:layout_height="200dp"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"
android:layout_alignTop="#+id/yourTurnListView"
android:layout_marginTop="200dp"/>
<TextView
android:id="#+id/theirTurnTextView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_above="#+id/yourTurnListView"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"
android:text="#string/their_turn"/>
<ImageView <!-- I want this to be fixed -->
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/imageView"
android:src="#drawable/ic_add_circle"
android:layout_below="#+id/theirTurnListView"
android:layout_alignRight="#+id/yourTurnListView"
android:layout_alignEnd="#+id/yourTurnListView"/>
</RelativeLayout>
Thanks
ScrollView can not be used in conjuction with ListView, ListView will not work properly.
If you really want to do this, try this code:
<FrameLayout>
<ScrollView/>
<ImageView/>
</FrameLayout>
I have a ScrollView which contains EditText, but the problem is it doesn't show properly in the emulator and on a physical device. Can anyone see any problems with my code?

Did you try adding the following attribute to the ScrollView?
xmlns:android="http://schemas.android.com/apk/res/android"
Try using:
<EditText
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="TestText"
/>
You might want to use the conditions : wrap_content, fill_parent or match_parent as using these allows your view elements to adjust accordingly to the device screen which can vary.
Also you might want to add an android:id="#id/myIdentifier" to that EditText so you can link it to whatever process you have going on in your app.
I today added a scrollview to my app. I wanted something like google now cards. It worked, but I want it to be fullscreen, but on the bottom. On the bottom i got a EditText and a Button and i want the scrollview to stop there, so that they are both visible. How can i do that? :s
That's my activity:

I hope you can help me
Thanks a lot!
You haven't said what is happening so its hard to say what the problem is. However, yo make this the way it sounds you want I would suggest adding the property
android:layout_alignParentBottom="true"
to your LineareLayout with the EditText and the Button. See if that works. Something like
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="10dp"
android:id="#+id/linearLayout"
android:layout_alignParentBottom="true"> <!-- Add this line here -->
The parent of your EditText and Button is a LinearLayout but they have properties such as these
android:layout_alignTop="#+id/sendButton"
android:layout_toLeftOf="#+id/sendButton"
android:layout_alignBottom="#+id/sendButton"
android:layout_alignLeft="#+id/scrollView"
but these are properties of a RelativeLayout so they won't have any effect, at least not any wanted effect, on Views whos parent is a LinearLayout.
See The Docs for the properties that each ViewGroup has.
