android 如何动态布局自定义view,不用XML.

linearlayout.addView(View youView, LayoutParams params);这样还行吗?

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);

Answer 2

自定义布局么？你是写自己写一个类似于LindearLayout 的布局类，还是想用代码布局。不使用xml
如果想用代码布局，可这样写
//定义一个线性布局
LindearLayout tp = new LindearLayout (this);
//定义一个布局参数类（用于定义Button在线性布局中的参数）
LayoutParams ltp = new LayoutParams(LayoutParams.WARP_CONTENT,LayoutParams.WARP_CONTENT);
Button lbt = new Button(this);
tp.addView(lbt,ltp);//将Button加入到线性布局中。
