Is it possible to only change only a part of a TextView?

Question

A little more specific. I want to know if it is possible to update a number that is saved in a TextView or if I have to use two TextViews.
What I have atm in the XML-File:

<TextView
 android:id="@+id/UpInfo"
 android:layout_width="wrap_content"
 android:layout_height="wrap_content"
 android:text="Upgrade: 0 "/>

Now I want to change the 0 in android:text while the App is running. Is this possible? If yes how?

Thanks in advance

Use a variable and string concatenation:

int number = 1;
TextView textview = (TextView) findviewbyId(R.id.UpInfo);

textview.setText("Upgrade: " + number);

Or if you use a method like this:

public void updateText(int number){
  textview.setText("Upgrade: " + number);
}

Then you would call it like this:

updateText(2);

Result... Upgrade: 2

updateText(3);

Result.... Upgrade: 3

Yes,you can use Spannable string

final SpannableStringBuilder spannable = new SpannableStringBuilder(your string);

spannable.setSpan(span, 0, 1, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
txtView.setText(spannable);
