2,914 PointsHow to update a TextView using a String variable?
i do not understand how to use a getter method to update a text view...this is as far as i could go...
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
public class LandingActivity extends AppCompatActivity {
public Button thrustButton;
public TextView typeLabel;
public EditText passengersField;
public Spaceship spaceship;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_landing);
thrustButton = (Button)findViewById(R.id.thrustButton);
typeLabel = (TextView)findViewById(R.id.typeTextView);
passengersField = (EditText)findViewById(R.id.passengersEditText);
// Add your code here!
spaceship = new Spaceship("FIREFLY");
typeLabel = typeLabel.setText(spaceship.getShipType());
}
}
public class Spaceship {
private String shipType;
private int numPassengers = 0;
public String getShipType() {
return shipType;
}
public void setShipType(String shipType) {
this.shipType = shipType;
}
public int getNumPassengers() {
return numPassengers;
}
public void setNumPassengers(int numPassengers) {
this.numPassengers = numPassengers;
}
public Spaceship() {
shipType = "SHUTTLE";
}
public Spaceship(String shipType) {
this.shipType = shipType;
}
}

3,680 PointsYou do not need to assign it to the typeLable variable.
Write this
typeLabel.setText(spaceship.getShipType());
Instead of
typeLabel = typeLabel.setText(spaceship.getShipType());
