import android.graphics.Color;
import android.view.Menu;
import android.view.SurfaceView;
import android.view.View;
import android.widget.Button;
import android.widget.RelativeLayout;
import android.widget.TextView;
import android.widget.Toast;
import android.widget.RelativeLayout.LayoutParams;
public class MainActivity extends Activity {
RelativeLayout rl;
SurfaceView sv;
Button b;
TextView tv;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
rl = (RelativeLayout) findViewById(R.id.rl);
sv = new SurfaceView(MainActivity.this);
RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams
((int) LayoutParams.WRAP_CONTENT, (int) LayoutParams.WRAP_CONTENT);
params.addRule(RelativeLayout.CENTER_HORIZONTAL);
params.topMargin = 40;
sv.setLayoutParams(params);
sv.setBackgroundColor(Color.LTGRAY);
tv = new TextView(MainActivity.this);
b = new Button(MainActivity.this);
tv.setText("TextView");
b.setText("Button");
RelativeLayout.LayoutParams params1 = new RelativeLayout.LayoutParams
((int) LayoutParams.WRAP_CONTENT, (int) LayoutParams.WRAP_CONTENT);
RelativeLayout.LayoutParams params2 = new RelativeLayout.LayoutParams
((int) LayoutParams.WRAP_CONTENT, (int) LayoutParams.WRAP_CONTENT);
params1.addRule(RelativeLayout.CENTER_HORIZONTAL);
params2.addRule(RelativeLayout.CENTER_IN_PARENT);
params1.topMargin = 75;
tv.setLayoutParams(params1);
b.setLayoutParams(params2);
rl.addView(sv);
rl.addView(tv);
rl.addView(b);
b.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
Toast.makeText(getBaseContext(), "Cool Buddy",
Toast.LENGTH_SHORT).show();
}
