using WebView in Android version 5.x May report the following error

android.view.InflateException: Binary XML file line #24: Error inflating class android.webkit.WebView

solution 1:

use createConfigurationContext () method to get the Context

public class LollipopFixedWebView extends WebView {

    public LollipopFixedWebView(Context context) {
        super(getFixedContext(context));
    }

    public LollipopFixedWebView(Context context, AttributeSet attrs) {
        super(getFixedContext(context), attrs);
    }

    public LollipopFixedWebView(Context context, AttributeSet attrs, int defStyleAttr) {
        super(getFixedContext(context), attrs, defStyleAttr);
    }

    @TargetApi(Build.VERSION_CODES.LOLLIPOP)
    public LollipopFixedWebView(Context context, AttributeSet attrs, int defStyleAttr, int defStyleRes) {
        super(getFixedContext(context), attrs, defStyleAttr, defStyleRes);
    }

    public LollipopFixedWebView(Context context, AttributeSet attrs, int defStyleAttr, boolean privateBrowsing) {
        super(getFixedContext(context), attrs, defStyleAttr, privateBrowsing);
    }

    public static Context getFixedContext(Context context) {
        // Android Lollipop 5.0 & 5.1
        if (Build.VERSION.SDK_INT >= 21 && Build.VERSION.SDK_INT <= 22) 
            return context.createConfigurationContext(new Configuration());
        return context;
    }
}

solution 2:

in the build.gradle of the project, appcompat version 1.1.0 May be buggy, use the following version to solve the problem

implementation 'androidx.appcompat:appcompat:1.2.0'
