android怎么获取自定义viewgroup的xml

Answer 1

可以直接new View来得到View对象来实现代码布局。以下为示例代码： 1.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); 2.相对布局 RelativeLayout relativeLayout = new RelativeLayout(this); setContentView(relativeLayout); AbsoluteLayout abslayout=new AbsoluteLayout (this); 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); 3.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);
