public
void
onCreate(Bundle
savedInstanceState) {
02
super
.onCreate(savedInstanceState);
03
//确定界面的布局
04
AbsoluteLayout
abslayout=
new
 
AbsoluteLayout
(
this
);
05
setContentView(abslayout);
06
//创建一个button按钮
07
Button
btn1 =
new
 
Button(
this
);
08
btn1.setText(”
this
 
is
a button”);
09
btn1.setId(
1
);
10
//确定这个控件的大小和位置
11
AbsoluteLayout.LayoutParams
lp1 =
12
new
 
AbsoluteLayout.LayoutParams(
13
ViewGroup.LayoutParams.WRAP_CONTENT,
14
ViewGroup.LayoutParams.WRAP_CONTENT,
15
0
,
100
);
16
abslayout.addView(btn1,
