android - 向每个 ViewPager 幻灯片添加多个图像和文本

Question

我有一个包含 3 张幻灯片的 ViewPager。我希望能够在每张幻灯片上添加 3 张图片和几个不同的文本标签。我目前拥有的代码允许我向每张幻灯片添加单个图像。我对如何为每张幻灯片使用多个图像和文本感到困惑。任何帮助将不胜感激。

public class ImageAdapter extends PagerAdapter {

    private final Context context;
    private final int[] GalImages = new int[] {
        R.drawable.workout_widget_master,
        R.drawable.workout_widget_master,
        R.drawable.workout_widget_master
    };

    ImageAdapter(Context context){
        this.context=context;
    }
    @Override
    public int getCount() {
        return GalImages.length;
    }

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

    @Override
    public Object instantiateItem(ViewGroup container, int position) {
        ImageView imageView = new ImageView(context);
        int padding = 10;
        imageView.setPadding(padding, padding, padding, padding);
        imageView.setScaleType(ImageView.ScaleType.MATRIX);
        imageView.setImageResource(GalImages[position]);
        container.addView(imageView, 0);
        return imageView;
    }

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

public class ViewPagerAdapter2 extends PagerAdapter {

Context context;
String[] image1;
String[] description;


LayoutInflater inflater;

public ViewPagerAdapter2(Context context, String[] image1,String[] description) {
    this.context = context;
    this.image1 = image1;
    this.description=description;


}

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

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


    TextView des;

    inflater = (LayoutInflater) context
            .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    View itemView = inflater.inflate(R.layout.slider, container,
            false);
    des = (TextView) itemView.findViewById(R.id.slider_des);
    des.setText(description[position]);

     AQuery aq = new AQuery(itemView);
     aq.id(R.id.imageView1).image(image1[position], true, true, 0, 0, null, AQuery.FADE_IN, AQuery.RATIO_PRESERVE);

     ((ViewPager) container).removeView(itemView);



    ((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 description.length;

}

}

这正是您想要的实现...现在声明 textview contents 的变量，声明 imageviews，将它们绑定(bind)在一起...这应该可以工作...在您的 Activity 上按声明的顺序传递变量到适配器。该解决方案将完美运行。我使用查询从 url 获取图像。您可以简单地传递图像资源并通过 imageview.setImageResource(); 方法绑定(bind)它
