Question

How do i set the text of a TextView to a value of an integer from another class.

the main activity where i want the text set below

 @Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_my);


   TextView counterText = (TextView) findViewById(R.id.counter);


   counterText.setText();


}

the class below

public class Ship implements Serializable {

        private static int counter = 0;
        public int getCounter()
        {
            return counter;
        }

    }

Answer 1

For a starter this should help

Ship s=new Ship();
int i=s.getCounter();
String value=String.valueOf(i);
counterText.setText(value);

Answer 2

使用String.valueOf在TextView中显示Integer，如下所示：

counterText.setText(String.valueOf(new Ship().getCounter()));

Answer 3

As far as i know you cannot access the UI component of 2nd activity while being in first activity. So the best way is to pass the value through putExtra method of intents and then set it to textview in the onCreate of 2nd activity by getting it. Here is link which shows this method: http://mobileorchard.com/android-app-development-using-intents-to-pass-data-and-return-results-between-activities/
