 setContentView(R.layout.activity_main);

 //初始化控件
 lv = (ListView) findViewById(R.id.lv);
 gv = (GridView) findViewById(R.id.gv);
 button = (Button) findViewById(R.id.change);

 //设置适配器
 lv.setAdapter(new MyAdapter());
 gv.setAdapter(new MyAdapter());

 //为按钮设置点击事件
 button.setOnClickListener(new View.OnClickListener() {
  @Override
  public void onClick(View v) {
   if (isLvShow){
    lv.setVisibility(View.GONE);
    gv.setVisibility(View.VISIBLE);
   }else {
    lv.setVisibility(View.VISIBLE);
    gv.setVisibility(View.GONE);
   }

   //对显示或隐藏进行取反
   isLvShow = !isLvShow;
   isGvShow = !isGvShow;
  }
 });
}

class MyAdapter extends BaseAdapter{

 @Override
 public int getCount() {
  return 20;
 }

 @Override
