I am struggling to figure out why my relativelayout screen is not filling the entire screen. I have tried a number of things, but the horizontal space of the screen never appears filled. What am i doing wrong?
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:id="#+id/splashscreen"
android:background="#color/splashScreenBackgroundColor"
>
<ImageView
android:id="#+id/imgLogo"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:src="#drawable/ic_launcher" />
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginBottom="10dp"
android:textSize="12sp"
android:textColor="#454545"
android:gravity="center_horizontal"
android:layout_alignParentBottom="true"
android:text="MyAppName"
/>
</RelativeLayout>
The old name is deprecated, change the values to this..
android:layout_width="match_parent"
android:layout_height="match_parent"
Adding singletop will replace the last instance of your activity so if that solved your problem maybe you are instantiating your activity more than once somewhere, and that is why didnt worked before.
I figured out a solution. I added
"
android:launchMode="singleTop"
"
to the relativelayout and it solved the problem!

The following image might further clarify my problem:
I have a RecyclerView that inside a ScrollView. Scrolling the view after changing the orientation produces an output like the screenshot. (NOTE: I'm not sure if changing orientation has anything to do with this issue as I can't scroll in portrait mode)
It is as if there are two identical layouts on top of each other, but when the user scrolls, only the topmost layout moves but the other one stays still.
Here's my xml code:
<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"

Edit: This problem also occurs in portrait mode after I've changed orientation (portrait -> landscape -> portrait). If I don't change the orientation, everything works fine.
Adding android:configChanges="orientation|screenSize" in the Manifest solved the issue in this case.
It is similar to this issue
I'm writing an application and have come across a bit of an issue.
When working with a layout file, I have a 2 RelativeLayouts inside of a ViewFlipper.
The idea is that this page in particular is a welcome screen. The first RelativeLayout "welcomes" you to the app, and upon pushing a button, the user is led to the second RelativeLayout. In this layout there is a search bar that will allow the user to search for a certain criteria (specific to the app, not important) then display the results in a ListView.
Everything works correctly, but displaying the ListView seems to have some problems. The adapter is set properly, and I tested the method on another ListView in a test layout, and it worked fine. However something seems wrong with the ListView in the RelativeLayout. Here is the layout code
activity_welcome.xml
<ViewFlipper xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/welcomeFlipper"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:animateLayoutChanges="true"
android:background="#color/white"
tools:context="com.jacemcpherson.announcer.WelcomeActivity">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#color/white"
android:padding="40dp">
...
<!-- This code irrelevant, all's well :) -->
</RelativeLayout>
<RelativeLayout
android:layout_width="match_parent"

android:layout_width="match_parent"
android:layout_height="wrap_content"

</RelativeLayout>
</ViewFlipper>
I'm setting the adapter works like normal, but just in case I missed something, here's the line of code for that...
mListView.setAdapter(new ArrayAdapter<String>(
mContext,
android.R.layout.simple_list_item_1,
result // this is the array of results to be displayed in the list.
));
Thank you for your help, if I've missed something that in some way makes this unanswerable without further information, please let me know.
Change the layout_height from wrap_content to either match_parent or fill_parent.
This is explained very well by this answer.
I have a rather simple ListView row:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal" >
<TextView
android:id="#+id/tournament_name"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:textSize="25dp" />
<TextView
android:id="#+id/tournament_winner"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:textSize="25dp" />
</RelativeLayout>
When the text of "#+id/tournament_name"is long - it overlaps with the one from "#+id/tournament_winner" and I don't understand why.
I tried using android:singleLine="false"to no avail. I also tried using android:inputType="textMultiLine"as the docu says android:singleLine="false" is deprecated but then I get the warning: Attribute android:inputType should not be used with <TextView>: Change element type to
<EditText> ? so no good here as well.
I also tried using android:ellipsize="end" but this doesn't work. I assume it is because the text in the left TextView ("#+id/tournament_name") is NOT long enough to fill up the full width of the ListView (which code is not sowing here).
I was sure that if I use android:layout_width="wrap_content"the two TextView fields shouldn't overlap.
Here is an example (see the second line):
Any further ideas how this could be fixed?
android:layout_toLeftOf="#id/tournament_winner" in First TextView.
Also set android:maxLines="1" and Fix width for tournament winner because when it gets long tournament name cant see...
row.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal" >
<TextView
android:id="#+id/tournament_name"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_toLeftOf="#id/tournament_winner"
android:maxLines="1"
android:text="NAMEEEEEEEEEEEEEEEEEEEEEEEEEEE"
android:textSize="25dp" />
<TextView
android:id="#+id/tournament_winner"
android:layout_width="wrap_content" android:layout_marginLeft="10dp"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:text="WINER"
android:textSize="25dp" />
</RelativeLayout>
Thank you very much for your answer - sorry it took me some time to respond. I ended up using your android:layout_toLeftOf="#+id/tournament_winner" but left the single line and the margin to the left unused, as the result seemed perfect to me (hope this is also the case for other devices).
One thing though - in the first text view (tournament_name) I had to use android:layout_toLeftOf="#+id/tournament_winner"and not android:layout_toLeftOf="#id/tournament_winner" - pay attention to the added +. For some reason I get an error using android:layout_toLeftOf="#id/tournament_winner": Error: No resource found that matches the given name... so it seems that it is possible and NEEDED to define the resource in the time of calling it because the system doesn't know it before it was defined.
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal" >
<TextView
android:id="#+id/tournament_name"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_toLeftOf="#+id/tournament_winner"
android:layout_alignParentLeft="true"
android:textSize="25dp" />
<TextView
android:id="#+id/tournament_winner"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:textSize="25dp" />
</RelativeLayout>
You can use single text view in place of two and simply display both strings in one text view !!
I'm developing an Android 3.1. and above application.
On one activity I generate its layout dynamically. I'm using formdetail.xml as contentview:
#Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.formdetail);
Bundle extras = getIntent().getExtras();
if (extras != null)
{
currentFormId = extras.getString("FormId");
}
}
formdetail.xml :
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/detailLayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content" >
<Button
android:id="#+id/downloadFormsButton"
android:enabled="false"
android:layout_alignParentLeft="true"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_margin="10dp"
android:text="#string/download_forms_button" />
<TextView
android:id="#+id/formErrorMsg"
android:layout_alignParentRight="true"
android:layout_alignParentBottom="true"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:padding="10dp"
android:textSize="16dp" >
</TextView>
</RelativeLayout>
</LinearLayout>
downloadFormsButton and formErrorMsg must be always in form.
But using that xml I get this warning:
This RelativeLayout layout or its LinearLayout parent is useless
I need linearLayout to add TableLayouts programmatically.
How can I solve this warning?
Lint is correct in it's warning, your LinearLayout isn't doing anything useful, since its only child is a RelativeLayout. Remove the LinearLayout:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/detailLayout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<Button android:id="#+id/downloadFormsButton"
android:enabled="false"
android:layout_alignParentLeft="true"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_margin="10dp"
android:text="#string/download_forms_button" />
<TextView
android:id="#+id/formErrorMsg"
android:layout_alignParentRight="true"
android:layout_alignParentBottom="true"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:padding="10dp"
android:textSize="16dp" />
</RelativeLayout>
You either ignore it or right click your project. Click Build Path->Configure Build Path.... Under Android Lint Preferences look for UselessParent and set it's severity to ignore or click Ignore All.
EDIT:
I take that last part back. I think Ignore All will wipe all Lint warnings and errors.
I was also having the same issue with my app layout.
I don't know how and it is right way or not, but this get resolved after setting background attribute to both layouts.
Now there is no warning and working perfect. Hope it will also work for you.
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:background="#drawable/bg"
android:layout_height="match_parent" >
<FrameLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_marginBottom="10dp"
android:layout_marginLeft="10dp"
android:layout_marginRight="10dp"
android:background="#drawable/bg2"
android:layout_marginTop="10dp" >
<ImageView
android:id="#+id/img_BookImage"
android:layout_width="200dp"
android:layout_height="200dp"
android:scaleType="fitXY"
android:contentDescription="#string/India"
android:src="#drawable/india" />
</FrameLayout>
</FrameLayout>
That is just an warning from lint. Lint doesn't know you would later append views to this layout and it will warn you that you added an unnecessary extra view(increasing your layout depth).
You should just ignore the warning(If it really bothers you here is a link on how to remove warnings from lint).
I am trying to use a empty View to indicate the color for each item in a ListView.
The idea is that the rowColor View is just a 3dp wide line that should automatically size to the height of secondLine and thirdLine (note that all of the content is set in code including the background color of rowColor and that firstLine and thirdLine are often set to GONE).
It shows up perfectly in Eclipse's Graphical Layout but the rowColor does not show up at all on my phone (running 2.3.3) and all the views are stacked. Any idea how to fix it?
The following code for the list_row was adopted from here. I've provided all the code that I would think works based on that layout, but not even close. Does that layout still work?
list_row.xml:
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="?android:attr/listPreferredItemHeight"
android:padding="6dip">
<TextView
android:id="#+id/firstLine"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_alignParentLeft="true"
android:singleLine="true"
android:text="First Line" />
<View
android:id="#+id/rowColor"
android:background="#FF0000"
android:layout_width="3dp"
android:layout_height="fill_parent"
android:layout_below="#id/firstLine"
android:layout_alignParentBottom="true" />
<TextView
android:id="#+id/thirdLine"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_toRightOf="#id/rowColor"
android:layout_alignParentBottom="true"
android:layout_alignParentRight="true"
android:singleLine="true"
android:text="Third Line" />
<TextView
android:id="#+id/secondLine"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_toRightOf="#id/rowColor"
android:layout_alignParentRight="true"
android:layout_below="#id/firstLine"
android:layout_above="#id/thirdLine"
android:layout_alignWithParentIfMissing="true"
android:gravity="center_vertical"
android:singleLine="true"
android:text="Second Line" />
</RelativeLayout>
main.xml:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout

android:layout_width="fill_parent"

Thanks.
I tested your layout in several emulators (from 2.1 to 2.3.3) and it works fine, with or without setting the first TextView visibility to View.GONE.
It must be either a problem in your code elsewhere or a glitch of your specific device.
As a workaround, you can use:
android:layout_height="0dp"
for your rowColor View. Since you are already defining the position of the top and bottom limits with android:layout_below="#id/firstLine" and android:layout_alignParentBottom="true", the actual value of layout_height is irrelevant.
I ran into this recently, and I found that a View with no content apart from a background color will not appear in a RelativeLayout.
If you can, try converting your layout to a LinearLayout. This seems to work for me.
