Use SharedPreference for showing dialog or not. Try this code:

public boolean Show = false;

public void IntroSupport(){
    AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this);
    ImageView image = new ImageView(this);
    image.setImageResource(R.mipmap.ic_launcher);
    builder.setIcon(R.mipmap.service)
            .setTitle("Online Support :")
            .setView(image)
            .setMessage("Somme text")
            .setNegativeButton("GOT it!",null)
            .setPositiveButton("Don't Show Me Again", new DialogInterface.OnClickListener() {
                @Override
                public void onClick(DialogInterface dialog, int which) {
                    SharedPreferences.Editor editor = getSharedPreferences("mypref", MODE_PRIVATE).edit();
                     editor.putBoolean("dontshow", true);
                     editor.commit();
                }
            });
    builder.setCancelable(false);
    AlertDialog about = builder.create();
    about.show();
    TextView messageText = (TextView) about.findViewById(android.R.id.message);
    messageText.setGravity(Gravity.CENTER);
    Button nbutton = about.getButton(DialogInterface.BUTTON_NEGATIVE);
    nbutton.setTextColor(Color.BLACK);
}


    @Override
    public void onPageSelected(int position) {
        switch (position){
            case 0:
          getSupportActionBar().setTitle(Html.fromHtml("title :"+Pb));
                tabLayout.getTabAt(0).setIcon(R.mipmap.ic1vrai);
                tabLayout.getTabAt(1).setIcon(R.mipmap.ic__2vrai);
                break;
            case 1:
                SharedPreferences prefs = getSharedPreferences("mypref", MODE_PRIVATE); 
                show = prefs.getBoolean("dontshow", false);
                if(Show == false){
                    IntroSupport();
                }

                getSupportActionBar().setTitle(Html.fromHtml("("titl"+sus));
                tabLayout.getTabAt(1).setIcon(R.mipmap.ic_2faux);
                tabLayout.getTabAt(0).setIcon(R.mipmap.ic1faux);
                break;
        }
    }

I used your solution and adapted it to my situation. Worked great. Thank you! — payne, May 01 '19 at 17:20

You can store a value to the SharedPreferences if the user press on the Don't show me this again button. Then you should wrap your dialog stuff in an if clause which checks if the value in the SharedPreferences is set or not.

Here is the link to the documentation of the SharedPreferences: https://developer.android.com/reference/android/content/SharedPreferences.html
