Generate random color(s) using Android Studio and Java There may be some situations in which you need the feature to generate a random color.  For example, in a list of items, if you want to assign different colors to each item/row, you may have seen the WhatsApp Group Chat List, where each person's name is displayed in a different color.  I'll do it using a button click. You can do it according to your requirements/needs. >> View for Java >> View for Kotlin >> View for Compose Code Code Snippet Random rnd = new Random (); int color = Color . argb ( 255 , rnd . nextInt ( 256 ), rnd . nextInt ( 256 ), rnd . nextInt ( 256 )); activity_main.xml <?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= ...

How to get and save the screenshot of a specific part of the Screen? In this tutorial, we will learn how to get the Bitmap from any UI View and Save it to Storage/Gallery. For Example, we have a LinearLayout containing some child views such as ImageView(s), TextView(s), and maybe some more UI Views. On clicking a button we will save that LinearLayout as an image in storage/gallery. So by learning this technique you can save any UI View or Layout as an image in Storage/Gallery. >> Check For Java >> Check For Kotlin >> Check For Compose Code: activity_main.xml <?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" android:padding= ...

In this Tutorial, we will learn how to Request Single and Multiple Permissions. Note: I'll add some permissions for example purposes only you may apply the same on permissions you want. >> Check For Java >> Check For Kotlin >> Check For Compose Video: Code: AndroidManifest.xml <?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android= "http://schemas.android.com/apk/res/android" xmlns:tools= "http://schemas.android.com/tools" > <!--For Single Permission Example--> <uses-permission android:name= "android.permission.ACCESS_FINE_LOCATION" ...
