动态生成界面

首先要却这个界面的布局，是AbsoluteLayout，RelativeLayout还是其他，然后就可以再里面添加控件了： public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); //确定界面的布局 AbsoluteLayout abslayout=new AbsoluteLayout (this); setContentView(abslayout); //创建一个button按钮 Button btn1 = new Button(this); btn1.setText(”this is a button”); btn1.setId(1); //确定这个控件的大小和位置 AbsoluteLayout.LayoutParams lp1 = new AbsoluteLayout.LayoutParams( ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT, 0,100); abslayout.addView(btn1, lp1 ); } 一个界面可以布置一个布局，可以多个布局一起设计： public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); //设置界面的布局 RelativeLayout relativeLayout = new RelativeLayout(this); setContentView(relativeLayout); //添加一个AbsoluteLayout子布局,并给这个布局添加一个button AbsoluteLayout abslayout=new AbsoluteLayout (this); abslayout.setId(11); Button btn1 = new Button(this); btn1.setText(”this is a abslayout button”); btn1.setId(1); AbsoluteLayout.LayoutParams lp0 = new AbsoluteLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT,100,0); abslayout.addView(btn1, lp0 ); //将这个子布局添加到主布局中 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); //再添加一个子布局 RelativeLayout relativeLayout1 = new RelativeLayout(this); Button btn2 = new Button(this); btn2.setText(”this is a relativeLayout1 button”); btn2.setId(2); RelativeLayout.LayoutParams lp2 = new RelativeLayout.LayoutParams(ViewGroup.LayoutParams.FILL_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT); lp2.addRule(RelativeLayout.ALIGN_PARENT_TOP); lp2.addRule(RelativeLayout.CENTER_HORIZONTAL, RelativeLayout.TRUE); relativeLayout1.addView(btn2 ,lp2); //将这个布局添加到主布局中 RelativeLayout.LayoutParams lp11 = new RelativeLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT); lp11.addRule(RelativeLayout.BELOW ,11); relativeLayout.addView(relativeLayout1 ,lp11); }
