Android SDK ( Eclipse) : Typing Game ,How to Creat

First of all I'm Totally New To Android , Started Learning a week ago , so please be patient

second : I have a simple Typing Game that when you write a text inside the editText , it will compare it with the TextView above it and give you a dialog if the written text exactly the same or not,give you the time you took to write it in seconds and save the best score !

Actually I have more than one Thing to ask you guys about in this app,but the main thing is to make the app gives random sentences every time the user plays using an Array !

The other Stuff I Need to know listed below ,So thankful if you could help me in this too :

1- Create an AlertDialog When The then The EditText is empty with a resume Button , When the Dialog Shows , the Timer will Stop , when the user press resume button the timer will resume running normally and continue Playing !

2- I noticed a logical error in my EditText , Like when I press Enter the text will give a new line and after 3 or 4 times the layout will get ugly and messed up , I already limited the characters of it but I don't Know how to stop it from creating new Lines and messes up my App ..

3- I want to Disable the Enter Button in the softKeyboard while typing in the EditText ,and Actually want it to Link it with the Submit Button , like when user click it,it will automatically press the Submit Button rather than giving new lines and for faster writing !

**Here is The App Layout**

Here Is The MainActivity Code :

  public class MainActivity extends Activity {

  private int Lowest = 0;

  private static String File = "Best Score";

  Button   w;

  Button   q;

  TextView t;

  TextView b;

  TextView s;

  EditText e;

  private Timer ti;    //Timer object Initialization

  private int TimeCounter = 0; // Timer Initialization

  SharedPreferences BestScore ;

  @Override

  protected void onCreate(Bundle savedInstanceState) {

  super.onCreate(savedInstanceState);

  setContentView(R.layout.activity_main);

  w = (Button) findViewById(R.id.Submit);      // Referring Write Button By Id 

  q = (Button) findViewById(R.id.QuitGame);     // Referring Quit By Id 

  b = (TextView) findViewById(R.id.BestTimer);

  t = (TextView) findViewById(R.id.World);      // Referring TextView By Id 

  s = (TextView) findViewById(R.id.Seconds);

  e = (EditText) findViewById(R.id.Text); // Referring EditText By Id 

  e.setHint("Touch here to write ");

  BestScore = getSharedPreferences(File , 0);

  String LoadBestScore = BestScore.getString("Best Score", "000");

  int LoadNewMin = BestScore.getInt("New MInimum" , 000);

  Lowest = LoadNewMin;

  b.setText(LoadBestScore);  

  //Lunch Dialog Creation 

  AlertDialog.Builder d0 = new AlertDialog.Builder(this);

  d0.setTitle("Start Game");

  d0.setCancelable(false);

  d0.setMessage("Are you ready?");

  d0.setNegativeButton("No",new DialogInterface.OnClickListener() {

For The "When Empty" Dialog and Pausing , I Just Wrote the AlertDialog for you Guys To modify it to make it pause and Resume , Here is the code :

  else if (check2.equals(""))      //When The Text Is Empty !

  {


  AlertDialog.Builder d3 = new AlertDialog.Builder(MainActivity.this);

  d3.setTitle(" Empty Text?");

  d3.setMessage("You Didn't Write Anything yet !");

  d3.setNegativeButton("Quit game",new DialogInterface.OnClickListener() {

  @Override

  public void onClick(DialogInterface dialog, int which) {

  finish();

  }

  });

  d3.setPositiveButton("Resume",new DialogInterface.OnClickListener() {

  @Override

  public void onClick(DialogInterface dialog, int which) {

  ti.scheduleAtFixedRate(new TimerTask() {

  @Override

  public void run() {

  // TODO Auto-generated method stub

  runOnUiThread(new Runnable() {

  public void run() {

  TimeCounter++;

  s.setText(String.valueOf(TimeCounter)); 


  }

  });

  }

  }, 1000, 1000);                                               

  }

  });

  AlertDialog dx = d3.create();

  dx.show();

  }

I Know The Code is Long , I Really Appreciate Any help and please , use comments when writing codes so that I understand what u did cus I'm Still New to Android, Thanks For your Time !

Set android:singleLine="true" to your edit text in layout

And in activity set onkeylistener which looks for enter key tobe pressed.

[YourEditTextObject].setOnKeyListener(new OnKeyListener() {

            @Override
            public boolean onKey(View arg0, int arg1, KeyEvent arg2) {
                if(arg1==KeyEvent.KEYCODE_ENTER){
                    //Do whatever you do on click of submit button

                }
                return false;
            }
        });
