我的gridView适配器很好，直到最近我决定添加一个TextView和ImageView。我的图像一些出现一些不出现，我的TextViews完全不显示。我的整个gridView现在都是一场灾难D：我不知道如何。我到处搜索。我试过，但我仍然无法d：在gridAdapter中添加TextView和ImageView错误：文本没有出现
我想：
UIL- tutorial adding TextView and ImageView < - 不工作
custom GridView with ImageView and TextView < - 不工作
这里是我的代码：
public class MyGridViewAdapter extends BaseAdapter {
ArrayList<Integer> images = new ArrayList<>();
ArrayList<String> imageNames = new ArrayList<>();
Context context;
private Resources resources;
public MyGridViewAdapter(Context context, ArrayList<Integer> images, ArrayList<String> imageNames)
{
this.context = context;
this.images = images;
this.imageNames = imageNames;
}
@Override
public int getCount() {
return images.size();
}
@Override
public Object getItem(int position) {
return images.get(position);
}
@Override
public long getItemId(int position) {
return position;
}
private static class ViewHolder
{
ImageView imageView;
TextView textView;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder currentViewholder;
ImageView imageView;
TextView textView;
LinearLayout outerLayout;
LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
//recycling logic
if (convertView == null) {
convertView = (LinearLayout) inflater.inflate(R.layout.grid_images, null);
}
currentViewholder = new ViewHolder();
currentViewholder.imageView = (ImageView) convertView.findViewById(R.id.ivGrid_images);
currentViewholder.textView = (TextView) convertView.findViewById(R.id.tvGrid_images);
ImageLoader imageLoader = ImageLoader.getInstance();
imageLoader.displayImage("drawable://" + images.get(position),currentViewholder.imageView);
currentViewholder.textView.setText(imageNames.get(position));
Log.d("TextView", imageNames.get(position));
Log.d("TextView" , String.valueOf(images.get(position)));
return convertView;
}
}
我做错了什么？请帮助：<它在我添加TextView之前完全正常：<
使用'ViewHolder'在getView方法得到它正常工作 –
@ρяσѕρєяK我想..像我刚才提到的链接..但仍无法正常工作.. – Michimcchicken
@ρяσѕρєяK无需等待在getView中使用什么？它的内部getView不是：你是否意味着if（convertView == null）isit？如果是，我试着......如果没有，请告诉我如何在getView D中使用： – Michimcchicken
