As you can see on the upper image, there are align options "to RightOf=button", "below=button" when you drag something, but when I drag something nothing like that is shown. Can anyone help me fix that?
<?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"
app:layout_behavior="#string/appbar_scrolling_view_behavior"
tools:context=".MainActivity"
tools:showIn="#layout/activity_main">
<TextView
android:id="#+id/text_witaj_uzytkowniku"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/witaj_uzytkowniku" />
</RelativeLayout>
Honestly, I prefer to use ConstraintLayout as the root. I believe it is much easier to use with the drag and drop tool.
When using it make sure that all objects are connected to each other(or the parent) at least once vertically and once horizontally.
How this looks in the code:
<androidx.constraintlayout.widget.ConstraintLayout
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">
<TextView
android:id="#+id/textView9"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginStart="24dp"
android:layout_marginTop="24dp"
android:text="TextView"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent" />
<TextView
android:id="#+id/textView10"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="16dp"
android:text="TextView"
app:layout_constraintStart_toStartOf="#+id/textView9"
app:layout_constraintTop_toBottomOf="#+id/textView9" />
</androidx.constraintlayout.widget.ConstraintLayout>
You can also adjust the distances using the side panel.
To use the layout you just need to type Constraint layout in the Pallete and drag it (if it is not installed, there will be a download)
Set position of your textview then try to add another view by dragging
<?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"
app:layout_behavior="#string/appbar_scrolling_view_behavior"
tools:context=".MainActivity"
tools:showIn="#layout/activity_main">
<TextView
android:id="#+id/text_witaj_uzytkowniku"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentTop ="true"
android:layout_alignParentLeft="true"
android:text="#string/witaj_uzytkowniku" />
</RelativeLayout>
I think instead of Relativelayout, you should use the CoordinatorLayout.
And if you continue with Relativelayout then go to file invalidate and restart your Android studio if this is cache related issue then resolved it.
Use Coordinator Layout to work. RelativeLayout is more of coding layout..

I'm currently using a Card View inside a recycler and the text is left-alligned despite my efforts.
Here is the Book Item Layout.
<?xml version="1.0" encoding="utf-8"?>
<androidx.cardview.widget.CardView
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_height="wrap_content"
android:layout_width="match_parent"
app:cardCornerRadius="4dp"
app:cardElevation="5dp"
app:cardUseCompatPadding="true"
app:cardBackgroundColor="#color/white">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
>
<TextView
android:id="#+id/bookTitleTextView"
android:layout_width="wrap_content"
android:layout_height="match_parent"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent"
app:layout_constraintTop_toTopOf="parent"
app:layout_constraintBottom_toBottomOf="parent"
android:layout_gravity="center_horizontal"
/>
</LinearLayout>
</androidx.cardview.widget.CardView>
Here is the recycler itself.
<?xml version="1.0" encoding="utf-8"?>
<androidx.recyclerview.widget.RecyclerView
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/bookRecycler" />
This is the current output.

As you can see the text is not centered.
I tried using layout gravity to center the text which didn't work.
I also tried using a constraint layout on the text view and using constraints to center the text without any luck.
android:layout_gravity = "center" has already been attempted.
Any advice on what I'm overlooking would be great.
Thank you.
add android:gravity="center" for LinearLayout and you are good to go
I see your LinearLayout have only one child and no special attributes, so you can even remove whole LinearLayout - place TextView straight inside CardView, which extends FrameLayout. For centering childs inside FrameLayout you may also use android:gravity="center" for parent and/or android:layout_gravity="center" for child
<?xml version="1.0" encoding="utf-8"?>
<androidx.cardview.widget.CardView
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_height="wrap_content"
android:layout_width="match_parent"
android:gravity="center"
app:cardCornerRadius="4dp"
app:cardElevation="5dp"
app:cardUseCompatPadding="true"
app:cardBackgroundColor="#color/white">
<TextView
android:layout_gravity="center"
... rest of code
android:gravity="center" is the correct code, instead of android:layout_gravity="center_horizontal"
I'm trying to remove that default menu button that appears on the left of my toolbar, so I can replace it with a custom button.
Here is the XML file for my toolbar:
<?xml version="1.0" encoding="utf-8"?>

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

android:layout_width="match_parent"
android:layout_height="?android:attr/actionBarSize"

</androidx.appcompat.widget.Toolbar>
</com.google.android.material.appbar.AppBarLayout>
<include layout="#layout/content_main" />
</androidx.coordinatorlayout.widget.CoordinatorLayout>
And here is the content_main.xml file:
<?xml version="1.0" encoding="utf-8"?>

android:layout_width="match_parent"
android:layout_height="wrap_content"
app:layout_behavior="#string/appbar_scrolling_view_behavior"
tools:context="MainActivity"
tools:showIn="#layout/toolbar">
</androidx.constraintlayout.widget.ConstraintLayout>
you might want to check https://stackoverflow.com/a/28291205/9891833 this link. I believe that this link is a good example of what you want to achieve. If you want a shortcut;
toolbar.getMenu().clear();
this might help you to remove the button. I hope these work for your case. Best of luck! :)
If you want a toolbar based design with customizable option you can go ahead with AppBarLayout wrapping a relativelayout or any other as per your interest. Handling is much easier in this case
im making a launcher app. in the tutorial it uses a Sliding Drawer which deprecated in Api 17. what could i use instead of this? i tried using the Slideup Panel from one of the posts on here link Below to the gitHub below
gitHubLinkhttps://github.com/umano/AndroidSlidingUpPanel
. but it wont allow me to use it in the way i want. i want the apps to appear in the drawer not in the main content. for some reason the second view only allows me to create a Text view which is for the handle to slide it up. any advice on what other methods i could implment to do the same job. it must slide up from the bottom. thanks for all the help
Ok guys Sussed it. Using The GitHub I posted in the question. what it did is because im aloud as many layouts as i like but only 2 children. i used a relative layout as my first layout with a gridView for my homescreen apps inside and closed it off. then i used anther Relative Layout Below with a textview inside then another Relative layout set with 80dp Padding at the top (the Size of my Text Handle) inside this one i had another gridview for my apps and closed it all off.
the Xml for it looks like this

My guess is that your layout is not scaling well to varied resolutions. Click the Preview All Screens option (in in the Graphical Layout section of Eclipse) to see if you can see the same cropping problem there. If so, you'll need to experiment with different layout weights, etc. to ensure that the layout works well across different device resolutions.
I guess problem can be about ScrollView. Try to change it and let me know result. Because I don't know for which reason its happening but sometimes with ScrollView view is getting hidden...
I am building an app that uses this library:https://github.com/umano/AndroidSlidingUpPanel to create a panel that slides on from the bottom of the screen when a user clicks an item in a listview.
However i dont want the slide up panel to take up the entire screen. I need there to be a gap at the top, between the panel and the action bar, of exactly 80dp.
I have tried everything i can think of (putting a spacer there with a transparant background, using layoutParams (gives error), etc). But nothing seems to work.
If someone could give me some suggestions as to what i could try next, i would much appreciate it.
The xml layouts are below.
Thanks for your time.

What about wrapping your SlidingUpPanelLayout in another layout, say FrameLayout and adding some good old paddingTop to the latter?
I have found a workaround. Draw the background of the pane transparent and put a padding top, but first the library must be modified like it's written here:
https://github.com/umano/AndroidSlidingUpPanel/issues/4
Hope this helps somebody in the future :)
