AlertDialog You need to use a Theme.AppCompat theme (or descendant) with this activity.

 

解决方案：

 

将：super(context);修改为 super(context,R.style.AppTheme); 

public class MyDialog
        extends AlertDialog
 
{
    private Context context;
    private Button ivConfirm, ivCancel;
    private ImageView popCancel;
    private TextView tvMessage;

    public MyDialog(@NonNull Context context) {
        super(context,R.style.AppTheme);
        this.context = context;
    }

}

 

<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
    <item name="windowActionBar">false</item>
    <item name="windowNoTitle">true</item>
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorAccent</item>
</style>
