As Havlicek said, create the textview using findViewByID and set the
text when button is clicked.
Sample code:
tv = (TextView) findViewById(R.id.TextView01);
tv.setText("This is sample.");
Button button = (Button) findViewById(R.id.Button01);
button.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
tv.setText("Button Clicked");
}
});
