android动态布局方法总结

//绝对布局
AbsoluteLayout abslayout=new AbsoluteLayout (this);
setContentView(abslayout);
Button btn1 = new Button(this);
btn1.setText(”this is a button”);
btn1.setId(1);
AbsoluteLayout.LayoutParams lp1 =
new AbsoluteLayout.LayoutParams(
ViewGroup.LayoutParams.WRAP_CONTENT,
ViewGroup.LayoutParams.WRAP_CONTENT,
0,100);
abslayout.addView(btn1, lp1);

//相对布局
RelativeLayout relativeLayout = new RelativeLayout(this);
setContentView(relativeLayout);
AbsoluteLayout abslayout=new AbsoluteLayout (this);
RelativeLayout.LayoutParams lp1 = newRelativeLayout.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);

//线性布局
LinearLayout ll = new LinearLayout(this);
EditText et = new EditText();
ll.addView(et);
//动态添加布局的方法1.               

LinearLayout  linearlayout = (LinearLayout)this.getLayoutInflater().inflate(R.layout.main1,null);               

setContentView(linearlayout);               

LinearLayout  linearlayout2 = (LinearLayout)this.getLayoutInflater().inflate(R.layout.main2,linearlayout);               

 //这样 main2 作为 main1的子布局 加到了 main1的 根节点下

//动态添加布局的方法2 addView.                       

LinearLayout  linearlayout  = (LinearLayout)this.getLayoutInflater().inflate(R.layout.main1,null);               

setContentView(linearlayout);               

LinearLayout  linearlayout2 = (LinearLayout)this.getLayoutInflater().inflate(R.layout.main2,null);               

linearlayout.addView(linearlayout2);
