我想做一个类似e代驾列表和地图的切换动作
如图:
现在已不加载图片没问题了,viewpage 左右切换也没问题但是当我集成到一起的时候发现问题
     TextView lv02 = (TextView)page02.findViewById(R.id.textView1);
       
        lv01.setAdapter(new HomeworkListAdapter(this));
        //lv02.setAdapter(new HomeworkListAdapter(this));
       
       
        //按钮栏
        buttons = new Button[pageViews.size()]; 
        buttonsLine = (ViewGroup)inflater.inflate(R.layout.activity_main, null); 
        button01 = (Button) buttonsLine.findViewById(R.id.pre_one_button);
        button02 = (Button) buttonsLine.findViewById(R.id.pre_two_button);
        
        buttons[0] = button01;
        buttons[1] = button02;         button01.setOnClickListener(new GuideButtonClickListener(0));
        button02.setOnClickListener(new GuideButtonClickListener(1));
       
       
        viewPager = (ViewPager)buttonsLine.findViewById(R.id.guidePages); 
        setContentView(buttonsLine); 
这种写法没问题但是加上我的Listview是报 空指针问题
 ImageAndTextListAdapter adapter=new ImageAndTextListAdapter(MainActivity.this, dataArray, lv01);
                lv01.setAdapter(adapter);
我知道原因是我没用new...或者说是没用setContentView(buttonsLine); 
我的listview的代码如下
public class ImageAndTextListAdapter extends ArrayAdapter<ImageAndText> {     private ListView listView;
    private AsyncImageLoader asyncImageLoader;     public ImageAndTextListAdapter(Activity activity, List<ImageAndText> imageAndTexts, ListView listView) {
        super(activity, 0, imageAndTexts);
        this.listView = listView;
        asyncImageLoader = new AsyncImageLoader();
    }     public View getView(int position, View convertView, ViewGroup parent) {
        Activity activity = (Activity) getContext();         // Inflate the views from XML
        View rowView = convertView;
        ViewCache viewCache;
        if (rowView == null) {
            LayoutInflater inflater = activity.getLayoutInflater();
            rowView = inflater.inflate(R.layout.driver_list, null);
            viewCache = new ViewCache(rowView);
            rowView.setTag(viewCache);
        } else {
            viewCache = (ViewCache) rowView.getTag();
        }
        ImageAndText imageAndText = getItem(position);
       
        // Load the image and set it on the ImageView
        String imageUrl = imageAndText.getImageUrl();
        ImageView imageView = viewCache.getImageView();
        imageView.setTag(imageUrl);
        Drawable cachedImage = asyncImageLoader.loadDrawable(imageUrl, new ImageCallback() {
            public void imageLoaded(Drawable imageDrawable, String imageUrl) {
                ImageView imageViewByTag = (ImageView) listView.findViewWithTag(imageUrl);
                if (imageViewByTag != null) {
                    imageViewByTag.setImageDrawable(imageDrawable);
                }
                
            }
        });
        if (cachedImage == null) {
imageView.setImageResource(R.drawable.icon_home);
}else{
imageView.setImageDrawable(cachedImage);
}
        TextView Name = viewCache.getName();
        Name.setText(imageAndText.getName());
        
        TextView State = viewCache.getState();
        State.setText(imageAndText.getState());
        
       
        //float MGSS=imageAndText.getMGSS();
        RatingBar MGSS1 = viewCache.getMGSS();
        MGSS1.setRating(imageAndText.getMGSS());
        
        TextView range = viewCache.getrange();
        range.setText(imageAndText.getrange());
        
        TextView count = viewCache.getcount();
        count.setText(imageAndText.getcount());
        
         TextView driving_experience = viewCache.getdriving_experience();
        driving_experience.setText(imageAndText.getdriving_experience());
        
        TextView address = viewCache.getaddress();
        address.setText(imageAndText.getaddress());
        
        TextView drivercode=viewCache.getdrivercode();
        drivercode.setText(imageAndText.getdrivercode());         return rowView;
    }}
我应该怎么改ImageAndTextListAdapter 才能不出错 求大神指教Androidlistviewimageviewviewpage
