Android Activity Lifecycle - Challenge Task 3 of 4
Override the onPause method. Then save the value of the CheckBox. Hint: Use isChecked() to get the value of the CheckBox, and use 'putBoolean' to store the value.
I passed tasks 1 & 2, and was able to add the override, but I have tried about 8 different things to add and save a checkbox... and am so tangled up in it now that I got a bad headace. I left a comment at the code that isn't passing.
import android.view.View;
import android.os.Bundle;
public class MainActivity extends Activity {
private static final String PREFS_FILE ="com.teamtreehouse.sharedpreferencesapp.preferences";
private static final String KEY_CHECKBOX = "key_checkbox";
private SharedPreferences mSharedPreferences;
private SharedPreferences.Editor mEditor;
public CheckBox mCheckBox;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mCheckBox = (CheckBox) findViewById(R.id.checkBox);
mSharedPreferences = getSharedPreferences(PREFS_FILE, Context.MODE_PRIVATE);
mEditor = mSharedPreferences.edit();
}
@Override
protected void onPause() {
super.onPause();
//I am lost around here
boolean checked = mCheckBox.isChecked();
mEditor.putBoolean("key_checkbox",true);
}
}

mEditor.apply();
