cardslib error resource android:attr/foregroundInsidePadding is private while targeting SDK 26

CardsLib Error: “android:attr/foregroundInsidePadding is private while targeting SDK 26”

This error arises when using CardsLib in your Android project and targeting SDK 26 or higher. The error message “android:attr/foregroundInsidePadding is private while targeting SDK 26” indicates that the attribute android:foregroundInsidePadding is no longer publicly accessible for use in your XML layouts.

Understanding the Issue

The android:foregroundInsidePadding attribute was introduced in Android SDK 23 (API Level 23) and was initially available for use in XML layouts. However, it was later marked as private in SDK 26 (API Level 26). This means that it can no longer be accessed directly within your XML layout files.

Solutions

Here are two solutions to resolve this error:

1. Update CardsLib Library

The most straightforward solution is to update your CardsLib library to a version compatible with SDK 26 and above. Check for updated versions of CardsLib on the official repository or via the package manager (e.g., Gradle). Ensure the library supports the minimum SDK version you are targeting.

2. Using the ForegroundDrawable Programmatically

If updating CardsLib isn’t an immediate option or you’re using a custom implementation, you can set the foreground drawable programmatically. Here’s how:

import android.graphics.drawable.Drawable;
import android.view.View;

// ...

// Get the view you want to apply foreground drawable to
View view = findViewById(R.id.your_view);

// Create your foreground drawable
Drawable foregroundDrawable = // Create the Drawable object
// You can use Drawable.createFromXml(context.getResources(),
// context.getResources().getXml(R.drawable.your_foreground_drawable))
// or use other Drawable constructors

// Set the foreground drawable
view.setForeground(foregroundDrawable);

// Set the desired padding programmatically if needed
view.setPadding(paddingStart, paddingTop, paddingEnd, paddingBottom);
