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 = 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);

 
//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);
