Android, Is it possible to format textview like System.out.format(“%02d”, n);?

问题

I have a table with different columns. instead of creating text view for each item i want to have one textview for each row. i want to add each item one by one to row string. because some items may have 1 digit and some others may have two digits, i want to format it.

in Java we do something like:

intn = 7;
System.out.format("%0d", n);      //  -->  "07"

is it possible do same way with textview? if yes how to do that. Thanks

回答1:

It is possible, refer to this

String text = String.format("%0d", n);
textView.setText(text);

Formatting strings

<string name="welcome_messages">Hello, %1$s! You have %2$d new messages.</string>

Resources res = getResources();
String text = String.format(res.getString(R.string.welcome_messages), username, mailCount);
