multiplication table in android using java

Question

Implementing a simple multiplication table in android. this code doesn't help in displaying the result. where am I going wrong?

@Override
protected void onCreate(Bundle savedInstanceState) {
    final int a;
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    // final TextView finalet = null;
    final TextView finale = (TextView) findViewById(R.id.finale);
    final EditText et = (EditText) findViewById(R.id.et);
    final String fromEt = et.getText().toString();

    Button gen = (Button) findViewById(R.id.gen);
    gen.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            try {

                int a = Integer.parseInt(fromEt);
                for (int voo = 0; voo <= 11; voo++) {
                    Integer sam = a * voo;
                    // finalet.setText(a*v);
                    // finale.setText(String.valueOf(sam));
                    finale.setText(sam);
                }
            } catch (NumberFormatException e) {

            }
        }
    });
}

Change this part:

int a = Integer.parseInt(fromEt); 

to

int a = Integer.parseInt(et.getText().toString());

like this:

public void onClick(View v) {
            try {

                int a = Integer.parseInt(et.getText().toString());
                for (int voo = 0; voo <= 11; voo++) {
                    Integer sam = a * voo;
                    finale.setText(String.valueOf(sam));
                }
            } catch (NumberFormatException e) {

            }
        }

But your according to your code you will see only the last i.e the number you entered * 11

If you want to show all you should do something like this:

finale.append(String.valueOf(sam) + " ");

inside the for loop
