我想要一个像这样在单个活动中有多个页面的应用程序

我正在尝试制作一个包含许多笑话的简单应用程序，如果我点击下一个按钮应该导航到下一个文本（笑话），怎么可能在谷歌和这个网站上搜索很多但我不知道，我Textswitcher也在找，但这不是我真正想要的，请帮助我..

有一种叫做 ViewPager 的东西将完全适合您的目的！

第一：为笑话页面创建一个xml布局来填充viewpager（即一个带有textviews来填充文本等）。第二：编写一个适配器来用你的内容填充viewpager。第三：在主布局中添加一个 viewpager。第四：将适配器设置为viewpager。

viewpager 适配器的示例代码供您开始使用。

public class ViewPagerAdapter extends PagerAdapter {

Context context;
int[] image;
String[] description;


    LayoutInflater inflater;

    public ViewPagerAdapter(Context context, int[] image,String[] description) {
        this.context = context;
        this.image = image;
        this.description=description;

    }

    @Override
    public boolean isViewFromObject(View view, Object object) {
        return view == ((LinearLayout) object);
    }

    @Override
    public Object instantiateItem(ViewGroup container, int position) {

        ImageView img;
        TextView des;

        inflater = (LayoutInflater) context
                .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        View itemView = inflater.inflate(R.layout.slider, container,
                false);

        img = (ImageView) itemView.findViewById(R.id.imageView1);
        img.setBackgroundResource(image[position]);
        des = (TextView) itemView.findViewById(R.id.slider_des);
        des.setText(description[position]);




        ((ViewPager) container).addView(itemView);

        return itemView;
    }

    @Override
    public void destroyItem(ViewGroup container, int position, Object object) {
        ((ViewPager) container).removeView((LinearLayout) object);

    }

    @Override
    public int getCount() {
        // TODO Auto-generated method stub
        return image.length;
    }

}

上述适配器适用于接受整数数组来存储资源（本例中为图像）的 viewpager。，以及图像标题的字符串数组。

对于适配器的 viewpager 布局，您必须创建一个带有 imageview 和 textview 的布局。

现在在您的活动布局中添加一个 viewpager。

宣布

String[] description={"example 1","example 2","example 3"};
int[] images="R.drawable.one,R.drawable.two,R.drawable.three";

//declare  viewpager
ViewPager vp = (ViewPager) findViewById(R.id.vp);
ViewPagerAdapter adapt= new ViewPagerAdapter(this,images,description);
vp.setAdapter(adapt);

应该是这个！

对于下一个上一个按钮...将它们放在 viewpager 下方的布局中。在 onClick 上写：

vp.setCurrentItem(vp.getCurrentItem() + 1); // for next
vp.setCurrentItem(vp.getCurrentItem() - 1); //for previous
