How to set buttons in Android?

Question

hi!

I have 7 to 8 buttons in my application.

Like this.

How can I do this? I used:

LinearLayout ll = (LinearLayout)findViewById(R.id.searchdialog_layout);

ll.setOrientation(0);

Button btn = new Button(context);
btn.setBackgroundDrawable(getResources().getDrawable(R.drawable.bubble_layout));

btn.setPadding(4,0, 4, 0);

btn.setTextSize(14);

btn.setTextColor(Color.BLACK);

btn.setText("bubble" + " x");

ll.addView(btn) ;

But it didn't work.

Can anyone help?
