Try changing your app theme, perhaps the default is white, which on a white background will be invisible

<style name="AppTheme" parent="Theme.MaterialComponents.Light"> 
  <item name="colorPrimary">#FFFF00</item> 
  <item name="colorPrimaryDark">#FF00FF</item> 
  <item name="colorAccent">#00FFFF</item> 
</style>

I’m using the “Android-Rate” library in my application. I have a problem when I try to show the dialog.

When the dialog opens it has the sentence I put inside it, but I cannot see the button like in the image below:

As you can see, the text is showed but the buttons doesn’t appear, is like the button are invisible but if you click on the white part of the dialog, it opens the App Store page.

Here is my code:

AppRate.with(this)
            .setInstallDays(0) 
            .setLaunchTimes(3) 
            .setRemindInterval(2) 
            .setOnClickButtonListener(new OnClickButtonListener() { 
                @Override
                public void onClickButton(int which) {
                    Log.d(MainActivity.class.getName(), Integer.toString(which));
                }
            })
            .monitor();
AppRate.showRateDialogIfMeetsConditions(this);

I also put this code inside Strings.xml:

<resources>
<string name="app_name">Example</string>

<string name="rate_dialog_title">Rate this app</string>
<string name="rate_dialog_message">If you enjoy playing this app, would you mind taking a moment to rate it? It won't take more than a minute. Thanks for your support!</string>
<string name="rate_dialog_ok">Rate It Now</string>
<string name="rate_dialog_cancel">Remind Me Later</string>
<string name="rate_dialog_no">No, Thanks</string>

Can you help me resolving this problem?
