First off, apologies, I'm new to all this and I'm struggling with Android / Java. Ive spent days looking stuff up and I KNOW I'm doing something stupid but would appreciate someone to tell me why / where I'm going wrong.
The app is a simple quiz, puts a picture up, use a spinner to select the answer, press a button to submit, get a toast message to verify and add a score. I know the code is horrendous and a hack but I lack the knowledge to do it more elegantly (part of the reason I'm here). I am trying to place a while loop, using the variable sflags that will be counting up from 0 to 26. When I place it, I can never seem to place it correctly so it works. I suspect some of the code gets broken when I try and wrap it.
Here's the (terrible) code :
public class MainActivity extends Activity implements TextWatcher {
private static final String TAG = "MainActivity";
private EditText mName;
private EditText mEmail;
private ListView countrieslist;
private String comments;
private int score = 0;
private int sflags = 0;
private String emailok;
private String answer;
private String flags;
private Spinner spinnerct;
private Object countries;
// private AdapterView<ListAdapter> spinnerct;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
countries = getResources().getStringArray(R.array.flagnames);
mName = (EditText) findViewById(R.id.name);
mEmail = (EditText) findViewById(R.id.email);
mEmail.addTextChangedListener(this);
}
@Override
public void afterTextChanged(Editable s) {
emailok = s.toString();
String sub_but = getString(R.string.sub_but);
boolean valid = emailok.length() > 0 &&
emailok.toLowerCase().indexOf(sub_but) == -1;
View view = findViewById(R.id.imageButton1);
boolean isVisible = view.getVisibility() == View.VISIBLE;
if (isVisible == valid) {
// No animation required if both values are true or both values are
// false
return;
}
Animation anim;
if (valid) {
view.setVisibility(View.VISIBLE);
// Create a new animation object
anim = AnimationUtils.makeInAnimation(this, true);
} else {
// Create a new animation object
anim = AnimationUtils.makeOutAnimation(this, true);
view.setVisibility(View.INVISIBLE);
}
// Tell the view it's time to start animating
view.startAnimation(anim);
}
public void thequiz(View view) {
setContentView(R.layout.activity_quiz);
Toast.makeText(
this.getApplicationContext(),
"Thanks ! Now try to identify the flags of these European Countries!",
Toast.LENGTH_LONG
).show();
sflags = 0;
score = 0;
// LinearLayOut Setup
LinearLayout linearLayout = new LinearLayout(this);
linearLayout.setOrientation(LinearLayout.VERTICAL);
linearLayout.setLayoutParams(new LayoutParams(
LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT));

// Constructing the filename using "flag" + the item number from
// variable loop
