How to get string from strings.xml:
"getResources().getString(R.string.name_of_variable_in_stringsxmlfile);"
See this:

btnSpeak = (Button) findViewById(R.id.btnSpeak);
txtText = (EditText) findViewById(R.id.txtText);
// button on click event
btnSpeak.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View arg0) {
speakOut();
}
});
}
