is not auto generating XML codes for relative layout, it only works for constraint layout.
When I try to position a view inside a relative layout it only gets positioned at the top corner of the screen.
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity">
<Button
android:id="#+id/button7"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Button" />
</RelativeLayout
What should I do?
I faced the same issue and the i tried the following step;
Click on the magnet icon (next to the eye icon, top left, next to the Palette menu) so that it's not crossed out: this turns on Autoconnect.
this will now help you to move the button where ever you want to place it.
Try it and let me know.
Yes if you pull the component on ConstraintLayout, it will guess what you want and set the attributes for you.
For RelativeLayout, you need to make the attribute view visible and edit from there. You need to edit parameters like these:
android:layout_below="#id/name"
android:layout_alignParentLeft="true"
android:layout_toLeftOf="#+id/times"

I'm new to Android and I wonder why I can't drag and drop things like buttons to the display in the main.xml Graphical Layout? It seems like it's locked or something else that I can't figure out on myself. Help is preciated! Thanks!
EDIT: This is my code in xml file
<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/textview"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:text="#string/hello"
/>
You are not able to do so because you don't have a Layout in your XML. Given here is an example as to how to build a basic layout. You can also refer to the Relative Layout tutorial or Linear Layout tutorial for more details, as these are widely used layouts.
Given below is the sample code for your XML:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<TextView
android:id="#+id/textview"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="#string/hello" />
</LinearLayout>
You can replace Linear Layout with Relative Layout at your convenience. But do keep in mind that you can't use the graphical layout without having a layout. To drag and drop a layout, refer the image below:
Hope this helps.
If that's your code, then it seems that you might be trying to drag elements into the TextView since it is filling the entire layout. Try to remove the TextView and see if you are then able to drag and drop elements again. Either that or change it to:
<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/textview"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="#string/hello"
/>
I am a begginer Android Studio to. I have same problem about drag and drop in design screen (in GUI). I solve the problem by using "res/layout/content_main.xml" (left side of the screen). It works! but ı am not sure that is it the right way :)))
Drag and drop the elements onto the Outline area instead of the display itself.Worked for me.
I'm currently trying to place a progress bar on the top left corner of my screen. However, I'm not quite sure which way is the best way to do it. Should I create a progress bar programatically instead of creating it in the xml? Or should I change my layout around? Thanks. XML below.
XML CODE:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#drawable/background"
android:focusableInTouchMode="true"
android:orientation="vertical" >
<ImageView
android:id="#+id/imageView1"
android:layout_width="fill_parent"
android:layout_height="53dp"
android:layout_marginBottom="5dp"
android:src="#raw/topbar" />
<TextView
android:id="#+id/search_nameOfFeed"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center_vertical|center_horizontal"
android:text="Event Name"
android:textColor="#color/black"
android:textSize="18sp" >
</TextView>
<ListView
android:id="#+id/searchfeed_view"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_weight="0.83"
android:dividerHeight="10.0sp"
android:fadingEdge="none"
android:stackFromBottom="false"
android:transcriptMode="normal" >
</ListView>
</LinearLayout>
The best option for layout when you're wanting to position views in specific areas is FrameLayout or RelativeLayout
RelativeLayout will allow you to place each view relative to each other.
FrameLayout allows you to stack views in a z-index positioning.
Play with both and you may come up with results you're looking for.
The best way to design layouts in android is by creating them in XML so you should do it in XML. You can achieve what you want by adding your ProgressBar before your ImageView
I doubt this is what you're looking for exactly, but another way you might want to implement a non-intrusive progress bar is to put it in the title bar of the activity. Check out this for an example of how to do this.
You can create it either way (In XML or Programatically). If you created it progamatcially, set the gravity to top and if you are creating in XML, use Relative Layout instead of Linear Layout and use android:layout_gravity="top|left". If you want to show it at the center follow the link
SOLVED: The layout_height parameter was set to Match_parent in the buttonbar definition. Changed to wrap_content.
I'm currently working on a new App which has a series of buttons at the top of the main screen. the "buttonBar" XML defines a linearLayout and is later nested within another linearLayout.
The buttons appear fine and work however if I then put a text view beneath the include statement the text does not appear. I think that it is actually appearing behind the buttons. I assumed that because it was within a parent linearLayout that it would appear after the included (nested) nested layout.
please could someone explain why this is not occurring and point me in the right direction to solve it.
much appreciated,

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"

<include layout="#layout/buttonheader"/>
<TextView android:layout_width="wrap_content"
android:layout_height="wrap_content"

Set height and width of the included layout buttonheader
SO that you can see this included layout in your layout
I have a simple XML Layout, in which I would like to place a Button in the bottom right corner.
I first tried android:layout_gravity="bottom|right"
However, the result was the button gravitating toward the right side, but not the bottom.
I then tried "center" and that worked, but it remained unchanged in combination with "bottom".
It appears that something is stopping the button from gravitating to the bottom.
Any help is appreciated.
The Layout in which the button is placed has a gravity attribute, which will give you this effect. Eg:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="fill_parent"
android:layout_height="fill_parent" android:gravity="bottom|right">
<Button android:layout_width="wrap_content"
android:layout_height="wrap_content"></Button>
</LinearLayout>
Maybe the layout where you are placing this button does not go to the bottom of the screen.
Use hierarchyviewer to see what is happening. And the code posted by Cesar should give you something actually working...
Use RelativeLayout instead of LinearLayout. Not only does it really do what you want, but it actually uses less processing and displays more quickly than LinearLayout.
Instead of a LinearLayout, define your space with a RelativeLayout like:
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
Then, to put your button at the bottom right, add this to your button:
<Button android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_alignParentRight="true"
/>

PS: as always, I haven't tested this code, just typing in as I remember things.
After searching for a few hours, I was unable to find the exact answer to my situation. I'm currently using a RelativeLayout and all I have is a background image and a button. The problem I'm having is placing the button in the exact location I want it to be (a little offset from the center).
My first attempt was to modify the layout_margins of the button. While this worked for the current emulator I was working with (3.7in WVGA), the positioning of the button was slightly/way off for a different screen size (such as 3.2in HVGA).
I then attempted to modify the padding of the parent layout but got the same issue. My XML looks like this:
<?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:paddingLeft="98dip" android:paddingBottom="68dip" android:background="#drawable/background">
<Button android:id="#+id/starttimer"
android:background="#drawable/button"
android:layout_width="wrap_content" android:clickable="true" android:layout_height="wrap_content" android:layout_alignParentBottom="true"/>
</RelativeLayout>
Please let me know if I'm completely off with my approach. It seems like an extremely simple problem, and I'm bummed out that it's taken me so long to try to get it. Thanks for any help!
I take it that you want to center the button on the bottom of the parent with a little offset, try layout_centerHorizontal then add your preferred margin.
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:paddingLeft="98dip" android:paddingBottom="68dip" android:background="#drawable/background">
<Button android:id="#+id/starttimer"
android:background="#drawable/button"
android:layout_width="wrap_content" android:clickable="true" android:layout_height="wrap_content" android:layout_alignParentBottom="true" android:layout_centerHorizontal="true" android_marginLeft="5dp"/>
</RelativeLayout>
Absolute Layout is used for absolute positions of the control.
