java-如何在图标和工具栏标题之间​​设置空格

我试图在选择项目时更改工具栏的图标,已经这样做并且可以正常工作,但是标题和图标像这张图片一样紧密闭合.我想在他们之间留出空间,好吗？

   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) {
        final String Animal = "<font color='#e76541'>Animal</font>";
        getSupportActionBar().setdisplayShowHomeEnabled(true);
        getSupportActionBar().setIcon(R.mipmap.animal);
        setTitle(Html.fromHtml("Wallpapers : "+Animal));
        }

解决方法:

尝试使用

setTitle(Html.fromHtml(“&Wallpapers：” art);
