Displaying multiple lines of text and variables in an AlertDialog using setMessage()

Question

I need to display multiple lines of text in an Alert Dialog. If I use multiple setMessage() methods, only the last setMessage is displayed, as shown below.

final AlertDialog alertDialog = new AlertDialog.Builder(this).create();                 alertDialog.setTitle("Statistics:");                 alertDialog.setMessage("No. of attempts: " + counter);                 alertDialog.setMessage("No. of wins: " + counterpos);                 alertDialog.setMessage("No. of losses: " + counterneg); 

Is there a way to create a new line for each of these in the dialog? Like using \n in System.print.out(); method.

Thanks!

Answer 1

You can do something like this

String alert1 = "No. of attempts: " + counter; String alert2 = "No. of wins: " + counterpos; String alert3 = "No. of losses: " + counterneg; alertDialog.setMessage(alert1 +"\n"+ alert2 +"\n"+ alert3);    

Answer 2

You could just create one string of everything you want to show and add "\n" where you'd like the line breaks to be.

alertDialog.setMessage("No. of attempts: " + counter + "\n" +              "No. of wins: " + counterpos + "\n" +              "No. of losses: " + counterneg); 

Or even better to use a StringBuilder:

StringBuilder sb = new StringBuilder(); sb.append("No. of attempts: " + counter); sb.append("\n"); sb.append("No. of wins: " + counterpos); sb.append("\n"); sb.append("No. of losses: " + counterneg); alertDialog.setMessage(sb.toString()); 

And the best way to do it would be to extract the static texts into a string resource (in the strings.xml file). Use the %d (or %s if you want to insert strings rather than ints) to get the dynamic values in the right places:

<string name="alert_message">No. of attempts: %1$d\nNo. of wins: %2$d\nNo. of losses: %3$d</string> 

And then in code:

String message = getString(R.string.alert_message, counter, counterpos, counterneg); alertDialog.setMessage(message);
