        private TextView tv;
        private Button b;

        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);

            myLayout=new LinearLayout(this);		//实例化布局对象
            myLayout.setOrientation(LinearLayout.VERTICAL);	//设置

            setContentView(myLayout);	//加载布局
            layoutP=new LinearLayout.LayoutParams(WC,WC);

            tv=new TextView(this);
            b=new Button(this);

            myLayout.addView(tv,layoutP);//添加组件
            myLayout.addView(b,layoutP);

            tv.setText("这是tv文本");
            b.setText("这是b文本");
        }
}
