Question

I’m getting the error “Syntax error, insert “;” to complete ReturnStatement” in the following code on the line “return int i;”

public class RecordActivity extends Activity {

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_record);

    int i = intent.getIntExtra(MainActivity.EXTRA_INDEX, 0);
    int j = i+1;
    final String[]names = getResources().getStringArray(R.array.names);

    final TextView nameView = (TextView) findViewById(R.id.vNames);
    String vName = names[i];
    nameView.setText(vName);

    Button nextButton = (Button) findViewById(R.id.nextButton);
    nextButton.setOnClickListener(new OnClickListener() {
        public static onClickView(View v) {
            i=i+1;
            return int i;
        }
        }
    );
    }
    //...
}

I am trying to iterate the index of an array on button click and so am getting the onClick method to return the index ‘i’ so I can put it into a looping statement. I’ve checked all brackets close and can’t see where I would be missing the ‘;’. Any help on this would be appreciated.

Declare int i in the activity, then in the onClick just increment it:

public class RecordActivity extends Activity {
  int i;

@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_record);

i = intent.getIntExtra(MainActivity.EXTRA_INDEX, 0);
int j = i+1;
final String[]names = getResources().getStringArray(R.array.names);

final TextView nameView = (TextView) findViewById(R.id.vNames);
String vName = names[i];
nameView.setText(vName);

Button nextButton = (Button) findViewById(R.id.nextButton);
nextButton.setOnClickListener(new OnClickListener() {
    public void onClickView(View v) {
        i=i+1;
    }
    }
);
}
//...
