I am currently refreshing my android developement skills and came across the CalendarView component. I wanted to disable the scrolling of the calendar and instead enable the arrows to browse through the calendar.
What I want to know is the following:
How can I disable the scrolling from the CalendarView? And why does Android Studio show me the arrow browse-version in the Designer-Mode but compiles and runs the scroll-version of the calendar?
I am running an Android VM, a "Galaxy Nexus" with API 22. I also posted the "build.gradle" further below.
What Android shows me/What I want:
What Android Studio compiles & runs:
Here some code:

Use MaterialComponents Theme, it will most probably solve the issue.
In your values/themes file replace the parent them with this,
parent="Theme.MaterialComponents.DayNight.DarkActionBar"
If you don't want Action Bar then ,
parent="Theme.MaterialComponents.DayNight.NoActionBar"
And if you only want to show Light Coloured Calendar view regardless of Devices's theme use,
parent="Theme.MaterialComponents.Light.NoActionBar"
Thanks to Vaibhav Goyal i came across the solution.
The API level I used was to low (API 22, Android 5.1). Changing that to API 23 (Android 6.0) solved my problem. Now it shows me the CalendarView with arrow-navigation instead of the scroll version!
yourCalenenderId.addOnItemTouchListener(object : RecyclerView.SimpleOnItemTouchListener() {
override fun onInterceptTouchEvent(rv: RecyclerView, e: MotionEvent): Boolean {
return if (e.action == MotionEvent.ACTION_MOVE) {
true
} else {
super.onInterceptTouchEvent(rv, e)
}
}
})

After that I resync my project and rebuild, but nothing changes.
I tried to follow different tutorials and questions but none of them solved my problem. What am I missing?
Thanks in advance
After some days, I have found that the code has been generated, but in different folders, so that I cannot see them

Due to this, the class is not instantinated and I get something like this:-
Also, here a small picture of the error too:-
Thanks for everyone helping out there to solve this issue.
Please also inform if you need anything else.
try to add this line in your dependencies in build.gradle
implementation 'androidx.appcompat:appcompat:1.0.2'
implementation 'androidx.constraintlayout:constraintlayout:1.1.3'
implementation 'com.android.support:design:29.0.2'
don't worry about the difference between com.android..... and androidx.... This implementation androidx. automatically migrate the implementation if your android studio is higher than 3.2.
you can check this link.https://stackoverflow.com/a/58619780/10075771 it will help you understand also the situation :)
Hoping i help you in little way :)
try adding below dependencies
implementation 'com.android.support:appcompat-v7:23.1.1'
implementation 'com.android.support:design:23.1.1'
Hope this will work for you.

Why I am Not changing compiled SDK version 28 to 27
bcz I want to use Bottom app bar
Bottom App Bar Material Design
App Bars:Bottom- Material Design
This is a bug in 28.0.0 and the only fix(workaround) is adding this to your Build.gradle:
configurations.all {
resolutionStrategy.eachDependency { DependencyResolveDetails details ->
def requested = details.requested
if (requested.group == "com.android.support") {
if (!requested.name.startsWith("multidex")) {
details.useVersion "27.1.1"
}
}
}
}
Which somehow, this bypasses the issue and uses 27 support library for that. Otherwise, you may wanna update your Android Studio to canary channel version or using backward support library like 27.1.1 or etc.
This error was occurred in your Rendering Layout which is a part of Studio Not in any files or Library
Try adding "Base" before Theme in styles.xml as show : -
"Base.Theme.AppCompat.Light.DarkActionBar"
Please restart Android Studio by selecting the menu option "File" →
"Invalidate Caches / Restart"
Workarounds: Try rendering with M preview using AS v1.3 preview OR
use FrameLayout for designing and change to
android.support.design.widget.CoordinatorLayout while debugging.
I am building an android application that has two versions.One with Ad. and one with out Ad. . I've successfully integrated the AdMob in the application. but the Ads are not getting displayed on the screen.

What am i doing wrong here ? :(
I had the same issue and I fixed it by updating Google Play Services to the latest version on my mobile. So maybe try updating it from Play Store.
I just downloaded Android Studio and have created a new project.
Right off the bat, I'm getting two errors:
Error:(2) Error retrieving parent for item: No resource found that matches the given name 'android:TextAppearance.Material.Widget.Button.Inverse'.
Error:(2) Error retrieving parent for item: No resource found that matches the given name 'android:Widget.Material.Button.Colored'.
Here is my gradle:
apply plugin: 'com.android.application'
android {
compileSdkVersion 22
buildToolsVersion "22.0.1"
defaultConfig {
applicationId "com.example.test.testapp"
minSdkVersion 15
targetSdkVersion 22
versionCode 1
versionName "1.0"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:23.0.1'
}
and my installed packages:
What is messed up here? Thanks
In your gradle, compileSdkVersion is 22 while your support library version is 23. The two should match.
See Error retrieving parent for item: No resource found that matches the given name after upgrading to AppCompat v23
I also had same problem now. I tried below steps and worked perfectly.
In .gradle change like this
dependencies {
compile fileTree(include: ['*.jar'], dir: 'libs')
compile 'com.android.support:support-v13:23.0.1'
}
You'll get error in style file change it as below
<style name="AppTheme">
<!-- Customize your theme here. -->
</style>
modify your main_menu.xml
<menu 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" tools:context=".MainActivity">
<item android:id="#+id/action_settings" android:title="#string/action_settings"
android:orderInCategory="100" android:showAsAction="never" />
</menu>
In MainActivity remove AppCompatActivity like
MainActivity extends Activity
