Android 带图标和文本的gridview图像
@@Branislav-我也像你说的那样做了。它对我很有效,但当没有图像超过9N文本时,它也开始在第9个图像和文本的位置向我显示相同的第一个或ant随机图像和文本Android 带图标和文本的gridview图像,android,image,gridview,text,Android,Image,Gridview,Text,@@Branislav-我也像你说的那样做了。它对我很有效,但当没有图像超过9N文本时,它也开始在第9个图像和文本的位置向我显示相同的第一个或ant随机图像和文本 public class ImageAdapter extends BaseAdapter { private Context mContext; public ImageAdapter(Context c) { mContext = c; } public int getCount() { return mThu

在这方面,它是完美的,直到博物馆,但公园,它不工作;它显示数组mThumbIds中的任意随机图像和关联文本。是的,图像是可绘制的。使用Map或HashMap将您的值配对
HashMap<Integer, String> store = new HashMap<Integer, String>();
store.put(R.drawable.hotel1, "Hotels");
您可以为此创建自定义适配器类
public class MyAdapter extends ArrayAdapter<BindData> {
private LayoutInflater inflater;
private int layoutId;
public MyAdapter(Context context, int layoutId, BindData[] objects) {
super(context, 0, objects);
this.inflater = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
this.layoutId = layoutId;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder holder;
if (convertView == null) {
convertView = inflater.inflate(layoutId, parent, false);
holder = new ViewHolder();
holder.textView = (TextView) convertView.findViewById(R.id.textview);
holder.imageView = (ImageView) convertView.findViewById(R.id.imageview);
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}
//BindData data = getItem(position);
holder.textView.setText(titles[position]);
holder.imageView.setImageBitmap(imgs[position]);
return convertView;
}
}
mDatas在哪里
public class BindData {
Bitmap b;
String title;
BindData(Bitmap bitmap, String s) {
this.b = bitmap;
this.title = s;
}
}
private BindData[] mDatas;
static class ViewHolder {
TextView textView;
ImageView imageView;
}
@@nik博士-我做了sme和tey在u said教程中做的一样。仍然面临问题@@xjaphx-你能详细告诉我如何使用这个吗??bcz我是android新手
public class BindData {
Bitmap b;
String title;
BindData(Bitmap bitmap, String s) {
this.b = bitmap;
this.title = s;
}
}
private BindData[] mDatas;
static class ViewHolder {
TextView textView;
ImageView imageView;
