i want to make a simple timer of 60 sec. When i tap the button my timer begins. And when the time=0 then set text to some string. Help me how can i do it for android inside Activity:

```
package com.example.gameprocess;

public class GameProcess extends Activity {

private static int rez = 0;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.gameprocess);

 final TextView Textkolvo = (TextView)findViewById(R.id.kolvo);
 final TextView Texttime = (TextView)findViewById(R.id.texttime);
 final Button Butklik = (Button)findViewById(R.id.klik);

```

And when i tap this button my time have to begin...

```
 Butklik.setOnClickListener(new View.OnClickListener() {
    public void onClick(View v) {
        //Textkolvo.setText(String.valueOf(rez));
    }
});
}
}

```
