I went through different solutions from stackoverflow and other websites but still unsolved. When keyboard appears, the radio buttons go at the top of editText.
In onCreate Method of MainActivity class, I wrote this line:
getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_VISIBLE|WindowManager.LayoutParams.SOFT_INPUT_ADJUST_RESIZE);
In Android Manifest.xml, I added a line in Activity:
<activity android:name=".MainActivity"
android:windowSoftInputMode="adjustResize"
>
Following is the acitivtiy_main.xml:

Your EditText has a non-zero height (wrap_content), and is constrained to the top of the parent.
Your ListView has a fixed height (266dp), and is constrained to the bottom of the parent.
Your RadioGroup has a fixed height (47dp), and is constrained to be between the EditText and the ListView.
Consider what will happen when the available height (the height of the parent) is less than 266dp + 47dp + EditText height. Even simpler, consider what will happen if the available height is less than 266dp.
In these cases, the top of the ListView will actually be above the bottom of the EditText. This will "pull" the RadioGroup in opposite directions, and it will wind up overlaying itself on top of the EditText and the ListView.
There's no quick fix to solve this. Probably what you want to do is change how everything is sized and constrained. I'd recommend:
Leave the EditText the way it is
Change the RadioGroup to only be constrained to the bottom of the EditText
Change the ListView to have 0dp height, and constrain its top to the bottom of the RadioGroup and its bottom to the bottom of the parent
This will wind up giving all the "extra" space to the ListView.

I'm making a soundbox for me and my friends in android studio.
I've got a simple Scroll view, that I filled up with multiple constraintLayout that each contains 2 imageView with each of having a line of text under it.
The problem is that when I run the app, I only see the 2 first layouts, i've no idea what's going on and this is probably not the good way to do it.
What's the best solution here? Here is the xml code :

look like you are begginer.

look like your problem

You set the fix height. Change it to match_parent.
<androidx.constraintlayout.widget.ConstraintLayout. And change root layout to FrameLayout or remove it.
I'm using the following code to create a recycler view. The recyclerview has got a grid layout manager with an item count of up to 2 per row.

Unfortunately, the recycler view that I have nested within the ConstraintLayout is not scrolling at all. What am I missing? Does constraint layout support the same?
To solve RecyclerView scrolling issue with ConstraintLayout parent change your RecyclerView height from wrap_content to 0dp and add top and bottom constraints like below:
<androidx.recyclerview.widget.RecyclerView
android:id="#+id/category_rv"
android:layout_width="0dp"
android:layout_height="0dp"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintTop_toBottomOf="#+id/category_title"
app:layout_constraintBottom_toBottomOf="parent"/>
The error comes from
tools:layoutManager="androidx.recyclerview.widget.GridLayoutManager"
tools:itemCount="4"
replace it by
app:layoutManager="androidx.recyclerview.widget.GridLayoutManager"
app:spanCount="4"
I have a fragment containing a recyclerView.
When an item is clicked on in the recyclerView I set the recyclerview item background to green and change the "saveBtn" text to "Update".
I need to also be able to remove the "deletebtn" every time a user clicks on a recyclerView item, or hide it so that the UI looks somewhat like this:
How could this be done?
Method I am using to update UI on recyclerView click
public void onExerciseClicked(int position) {
saveBtn.setText("Update");
clearBtn.setText("Delete");
}

Using LinearLayout as a direct child of ConstraintLayout defeats the whole purpose of using ConstraintLayout. It is not a good practice to use nested layout from the performance point of view. Besides, if deleteBtn is direct child of ConstraintLayout, then setting the layout_width of saveBtn to match_constraint will enable it to take up the whole space if we change the visibility of deleteBtn to gone.
cgb_pandey's answer is great and it is the recommended approach since your root viewgroup is ConstraintLayout. However, I wanted to present you an alternative way to do this using your current LinearLayout approach.
All you need to do is to set the width of both bottoms to 0dp. This way, their weight would determine how much space they occupy. If both view are visible, each of them would have 50% of the total width of the screen. If only one of the buttons is visible, it would occupy the entire screen. Here's a code snippet to guide you:
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginLeft="20dp"
android:layout_marginRight="20dp"
android:orientation="horizontal">
<Button
android:id="#+id/save_btn"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_marginLeft="20dp"
android:layout_marginRight="20dp"
android:layout_weight="1"
android:background="#drawable/my_small_green_shape"
android:text="Save"
android:textColor="#ffffff"
android:textSize="20sp" />
<Button
android:id="#+id/clear_btn"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_marginLeft="20dp"
android:layout_marginRight="20dp"
android:layout_weight="1"
android:background="#drawable/my_small_red_shape"
android:text="Clear"
android:textColor="#ffffff"
android:textSize="20sp" />
</LinearLayout>
Not that this approach involves nesting layouts and this might affect performance in the long run and also complicate your layout code pretty fast.
I want to create an activity where i have 2 buttons at the bottom of the screen, and a scroll view above them. Inside of the scroll view i want a drop down menu where the user can select a series of exercises. How do I put the scroll view above the buttons and have them stay in the same spot when scrolling?

If you want to add a scrollview that stays above the two buttons, you can add a NestedScrollview inside the constraintlayout

I have a problem. Everything just looks compressed but my design layout in my IDE is normal as is. What could be the problem?
First pic: The output of the app. Everything is compressed. I have no idea what happened

You need to add constraints to your layout views, heres an example:
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/constraintlayout_intro"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#color/colorPrimaryDark"
android:paddingLeft="#dimen/spacing_normal"
android:paddingRight="#dimen/spacing_normal">
<br.com.informant.cegonheira.ui.component.CustomViewPager
android:id="#+id/viewpager_intro"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent" />
<androidx.appcompat.widget.AppCompatButton
android:id="#+id/btn_intro"
android:layout_width="200dp"
android:layout_marginTop="360dp"
android:layout_height="#dimen/spacing_big"
android:background="#drawable/background_rounded_green_gradient_button"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent" />
<me.relex.circleindicator.CircleIndicator
android:id="#+id/circle_indicator_intro"
android:layout_width="match_parent"
android:layout_height="#dimen/spacing_normal"
android:layout_marginTop="460dp"
app:ci_drawable="#drawable/ic_radio_white"
app:ci_drawable_unselected="#drawable/ic_radio_grey"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent" />
</androidx.constraintlayout.widget.ConstraintLayout>
Notice this in the last view(CircleIndicator):
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent"
This is what tells where the view is going to be "anchored", otherwise they just "float" like happened to yours.

Congratulations for your first app!
