I have tried it, but no do correct.
.java:
import android.app.Activity;
import android.os.Bundle;
import android.widget.LinearLayout;
import android.widget.Button;
public class helloworld extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
LinearLayout layout = (LinearLayout) findViewById
(R.id.mainlayout);
Button bt = new Button(this);
bt.setText("Button");
layout.addView(bt);
setContentView(layout);
}
}
main.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/
android"
android:id="@+id/mainlayout"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="@string/hello"
