Answer 1

I cant actually figure out what the increment textview means ....

May be adding more textviews or increasing the value inside the textview. I will go with later.

Context context;
TextView tv;
Button increamenter;
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
   setContentView(R.layout.my_layout);
   tv=(TextView)findViewById(R.id.textView1);
   incrementer=(Button)findViewById(R.id.button1);

    context=this;

   incrementer.setOnClickListener(new View.OnClickListener(){

        try
        {
            String presentValStr=tv.getText().toString();
            int presentIntVal=Integer.parseInt(presentValStr);
            presentIntVal++;
            tv.setText(String.valueOf(presentIntVal));
         }
         catch(Exception e)
         {
             e.printStackTrace();
             Toast.makeText(context,"Some error :(",2000).show();
         }
   });


}

In your class create:

       int score = 0;

And then;

       button.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                // score operation like score += increment_value;
                t1.setText(""+score);
            }
        });

If you need to "save" the score ocne you quit the application, you need to use SharedPreferences to show/update the value.
