使用ShowcaseView处理后按

Question

How can I handle a user pressing the back button, whilst a ShowcaseView is showing? I want to be able to hide the ShowcaseView when they press back.

Answer 1

ShowcaseView allows you to query if it is showing or not. So, if a user presses back and it is showing, simply hide it using Activity#onBackPressed() :

@Override
public void onBackPressed() {
    if (sv.isShowing()) {
        sv.hide();
    } else {
        super.onBackPressed();
    }
}

Try this :

 @Override
    public void onBackPressed() {
        // in if condition check showcaseview is show or hide
        if(isShowcaseViewShow==true) {
           // here hide your showcase view
        }
        else{
              // here perform back action if view already hide
            super.onBackPressed();
        }
    }
