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 ll = (LinearLayout)this.getLayoutInflater().inflate(R.layout.main1,null);                setContentView(ll);                LinearLayout ll2 = (LinearLayout)this.getLayoutInflater().inflate(R.layout.main2,ll);                //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 ll = (LinearLayout)this.getLayoutInflater().inflate(R.layout.main1,null);                setContentView(ll);                LinearLayout ll2 = (LinearLayout)this.getLayoutInflater().inflate(R.layout.main2,null);                ll.addView(ll2);
