4,086 PointsI not understand what I need to do mFuelLevel to pass the int extra into a string like in the video
In the video the member variable was already a string so he just use the intent get string but in the exercise the member variable is an int so when I try to follow what Ben did it did not work . I also try get int but that did not work can someone show me the proper code and explain it to me Here is the task: We previously added a FUEL_LEVEL to our spacecraft. Now in FlightActivity, we want to get the value that we put in the Intent. Start by declaring an Intent variable and getting the Intent used to start this Activity.
import android.os.Bundle;
public class FlightActivity extends Activity {
public int mFuelLevel = 0;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_flight);
// Add your code below!
Intent intent = getIntent();
mFuelLevel= intent.getStringExtra("FUEL_LEVEL");
}
}

You got the first bit right with the getIntent() but, the next bit was a bit trickier!
What you want to do is use the method getIntExtra() instead because the FUEL_LEVEL value was an integer! Take a look at the documentation here. I know, you may hate me for linking a documentation link (I feel the same sometimes) but, it actually explains it quite well here.
So, the method takes in two parameters - name
of the item you want to extra from. This should be provided as a string...
And a defaultValue
as an integer (Don't use quotes this time!). This is the value that will be returned by the method if the FUEL_LEVEL
value was not passed in to the method for some reason.
Hopefully this makes sense to you! If there's something you don't understand still, give me a shout and I'll try my best to explain it :)
