To fix that I'm going to use shared preferences.

I'm going to start by creating a shared preferences field and an editor field.

So private shared preferences mshared preferences and

then private sharedpreferences.editor meditor.

Now that I have these two fields I'm going

to initialize them right below setContentView.

So mSharedPreferences = getSharedPreferences.

And we'll need a preferences file name.

And then Context.MODE_PRIVATE.

Alt+Enter to create this constant, and

I'll call it my package name plus .preferences.

So com.teamtreehouse.golfscorecard.preferen-

ces.

Looks good.

Then I'll initialize the editor to our mSharedPreferences.edit.

Great.

Now we've got access to all the pieces we need and I can start saving the values.

I'll do that in the on pause method.

Make some space at the bottom and use control o to override the on pause method.

And the on pause method, I will want to save the score for

each whole end to a different shared preference.

Here is how I will do it.

First we need to loop through all the holes.

So for int I, equals zero, I less than M

holes.length, I plus plus.

We'll use the editor, so M editor.put.int.

Because we're storing an Int in our shared preference.

And we'll use a key of KEY_STROKECOUNT, which I'll create now.

Alt+Enter, key_strokecount.

Looks good.

And then I'm going to add to this key our index, I.

This is going to make 18 different keys for

our shared preferences, and is going to let us store 18 different values.

Then we need to put the value into that key which will be mHoles,

the holes at that index.get stroke count.

Perfect.

Then after the four loop and we've put all of our strokes into the appropriate key.

We need to call apply to set those changes.

Looks good.

Now that we've saved our value in onPause,

I'm going to retrieve them in onCreate and set them.

So for each hole, we're going to set strokes

equal to our SharedPreferences object.getInt, and we'll pass in our key,

which is KEY_STROKECOUNT plus the index,

and then we'll pass in a default value of 0.

And this will set our strokes for each hole.

All right.

Looks good.

Let's see what happens when we run it.

Now I'm going to put in some values 3, 2, 1, 1.

Maybe scroll to the bottom.

Put some in here.

Give it 10 for hole 15, that'll be easy to check, and

then I'll hit the back button to completely destroy the activity.

Let's go back into golf scorecard, and it looks like it saved our values.

Even the 10 we put for hole 15.

Great, it looks like our shared preferences are working.
