Question

I am using ToolBar in my project first time, so i do not know how to customized the toolbar in android. I need to centered title in to the tool bar and how to do that please

Answer 1

public void centerTitleAndSubtitle(Toolbar toolbar){
    // Save current title and subtitle
    final CharSequence originalTitle = toolbar.getTitle();
    final CharSequence originalSubtitle = toolbar.getSubtitle();

    // Temporarily modify title and subtitle to help detecting each
    toolbar.setTitle("title");
    toolbar.setSubtitle("subtitle");

    for(int i = 0; i < toolbar.getChildCount(); i++){
        View view = toolbar.getChildAt(i);

        if(view instanceof TextView){
            TextView textView = (TextView) view;


            if(textView.getText().equals("title")){
                // Customize title's TextView
                Toolbar.LayoutParams params = new Toolbar.LayoutParams(Toolbar.LayoutParams.WRAP_CONTENT, Toolbar.LayoutParams.MATCH_PARENT);
                params.gravity = Gravity.CENTER_HORIZONTAL;
                textView.setLayoutParams(params);

            } else if(textView.getText().equals("subtitle")){
                // Customize subtitle's TextView
                Toolbar.LayoutParams params = new Toolbar.LayoutParams(Toolbar.LayoutParams.WRAP_CONTENT, Toolbar.LayoutParams.MATCH_PARENT);
                params.gravity = Gravity.CENTER_HORIZONTAL;
                textView.setLayoutParams(params);
            }
        }

        // Restore title and subtitle
        toolbar.setTitle(originalTitle);
        toolbar.setSubtitle(originalSubtitle);
    }
}
