You need to add the TextView to the layout.
Here's the revised program:
package com.example.helloandroid;
import android.app.Activity;
import android.os.Bundle;
import android.widget.AbsoluteLayout;
import android.widget.TextView;
public class HelloAndroid extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// setContentView(R.layout.main);
AbsoluteLayout layout = new AbsoluteLayout(this);
TextView tv = new TextView(layout.getContext());
tv.layout(10,10,100,100);
tv.setText("Hello World! :-)");
layout.addView(tv);
setContentView(layout); }
}
