Firstly you need to set up a Button variable and assign it the id of the Button view you have created in your xml file. It should go something like this.

Button myButton = (Button) findViewById(R.id.button1);

Then you can use the method myButton.setText("whatever text you want");

if you already have a string variable set up called label you can simply add that into the brackets instead like

myButton.setText(label);

Hope this helps

Hi Daniel,

Thanks for the reply. I've tried using the string variable but I'm getting a compiler error.

Can you post your source code? it might be easier if I can take a look at the code you already have?

stringTest.java

String[] phoneNumberLabels = { "-home", "-work", "-mobile" };

Button saveButton = (Button) findViewById(R.id.saveButton); String label=getString(R.string.saveLabel); saveButton.setText("SAVE");

String.xml

<?xml version="1.0" encoding="utf-8"?> <resources> <string name="saveLabel">Save My Changes</string> <string name="label">Save</string> </resources>

Okay are you trying to set the text of the button equal to a value in your phoneNumberLabels array or a string resources in your strings.xml file?

in order to set the text equal to a value in your string resource folder use the following

saveButton.setText(R.string.save_button_text); you will also need something like this in your string resources file

<?xml version="1.0" encoding="utf-8"?> <resources> <string name="save_button_text">Save Button</string> </resources>

if you wish to set the text of your button to a value in an array use the following

saveButton.setText(phoneNumberLabels[1]) (or whatever position of the array you wish).

You can delete the line String label=getString(R.string.saveLabel);

I hope I understand what you are trying to do. As the java code appears correct I assume the problem must lie with the xml file somewhere.

If this doesn't help, on what line are you getting an error or does eclipse allow you to run the android app and the app stops while running?
