Answer 1

For the second thing

This should work:

public class TestActivity extends Activity implements Runnable, OnClickListener {
private TextView tv;
private ProgressDialog pd;
private Button btn;

@Override
public void onCreate(Bundle icicle) {
    super.onCreate(icicle);
    setContentView(R.layout.main);

    tv = (TextView) this.findViewById(R.id.tv);     
    btn = (Button)findViewById(R.id.btn);

    tv.setText("initial text");

    btn.setOnClickListener(this);
}

public void onClick(View v) {
    pd = ProgressDialog.show(TestActivity.this, "Please wait...", "Details here", true, false);

    Thread thread = new Thread(TestActivity.this);
    thread.start();
}
public void run() {
    try {
        Thread.sleep(5000);
    } catch (InterruptedException e) {
        e.printStackTrace();
    }

    handler.sendEmptyMessage(0);
}

private Handler handler = new Handler() {
    @Override
    public void handleMessage(Message msg) {
        pd.dismiss();
        tv.setText("text after 5 sec passed");
    }
};
}
