, already do it and the fin is working, but the title and the Close icon are together as shown in the picture. I want to set space between them, any idea please?

   public boolean onNavigationItemSelected(MenuItem item) {
    int id = item.getItemId();
    if (id == R.id.Fragment_art) {
        final String art = "<font color='#ffd159'>Art</font>";
        getSupportActionBar().setDisplayShowHomeEnabled(true);
        getSupportActionBar().setIcon(R.mipmap.art);
        setTitle(Html.fromHtml(" Wallpapers : "+art));
    } else if (id == R.id.Fragment_Material) {
        final String Material = "<font color='#4acfd9'>Material</font>";
        setTitle(Html.fromHtml(" Wallpapers : "+Material));
        getSupportActionBar().setDisplayShowHomeEnabled(true);
        getSupportActionBar().setIcon(R.mipmap.material);

    } else if (id == R.id.Fragment_Natural) {
        final String Natural = "<font color='#49a010'>Natural</font>";
        getSupportActionBar().setDisplayShowHomeEnabled(true);
        getSupportActionBar().setIcon(R.mipmap.natural);
        setTitle(Html.fromHtml(" Wallpapers : "+Natural));
    } else if (id == R.id.Fragment_Animal) {
