動態生成介面的方法很簡單
首先要卻這個介面的佈局，是AbsoluteLayout，RelativeLayout還是其他，然後就可以再裡面新增控制元件了：
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//確定介面的佈局
AbsoluteLayout abslayout=new AbsoluteLayout (this);
setContentView(abslayout);
//建立一個button按鈕
Button btn1 = new Button(this);
btn1.setText(”this is a button”);
btn1.setId(1);
//確定這個控制元件的大小和位置
AbsoluteLayout.LayoutParams lp1 =
new AbsoluteLayout.LayoutParams(
ViewGroup.LayoutParams.WRAP_CONTENT,
ViewGroup.LayoutParams.WRAP_CONTENT,
0,100);
abslayout.addView(btn1, lp1 );

}
一個介面可以佈置一個佈局，可以多個佈局一起設計：
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);

//設定介面的佈局
RelativeLayout relativeLayout = new RelativeLayout(this);
setContentView(relativeLayout);

//新增一個AbsoluteLayout子佈局,並給這個佈局新增一個button
AbsoluteLayout abslayout=new AbsoluteLayout (this);
abslayout.setId(11);
Button btn1 = new Button(this);
btn1.setText(”this is a abslayout button”);
btn1.setId(1);
AbsoluteLayout.LayoutParams lp0 = new AbsoluteLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT,
ViewGroup.LayoutParams.WRAP_CONTENT,100,0);
abslayout.addView(btn1, lp0 );
//將這個子佈局新增到主佈局中
RelativeLayout.LayoutParams lp1 = new RelativeLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT);
lp1.addRule(RelativeLayout.ALIGN_PARENT_TOP);
lp1.addRule(RelativeLayout.CENTER_HORIZONTAL, RelativeLayout.TRUE);
relativeLayout.addView(abslayout ,lp1);

//再新增一個子佈局
RelativeLayout relativeLayout1 = new RelativeLayout(this);
Button btn2 = new Button(this);
btn2.setText(”this is a relativeLayout1 button”);
btn2.setId(2);
RelativeLayout.LayoutParams lp2 = new RelativeLayout.LayoutParams(ViewGroup.LayoutParams.FILL_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT);
lp2.addRule(RelativeLayout.ALIGN_PARENT_TOP);
lp2.addRule(RelativeLayout.CENTER_HORIZONTAL, RelativeLayout.TRUE);
relativeLayout1.addView(btn2 ,lp2);

//將這個佈局新增到主佈局中
RelativeLayout.LayoutParams lp11 = new RelativeLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT);
lp11.addRule(RelativeLayout.BELOW ,11);
relativeLayout.addView(relativeLayout1 ,lp11);
}
