StartActivity

//如果启动ThirdActivity需要两个参数，封装一个方法使ThirdActivity所需要的数据全部都在方法参数中体现出来了
    public static void actionStart(Context context,String data1,String data2){
        Intent intent=new Intent(context,ThirdActivity.class);
        intent.putExtra("param1",data1);
        intent.putExtra("param2",data2);
        context.startActivity(intent);
    }
