源码只显示了数字并没有图片 请问要怎么写才能把图片和TEXTVIEW结合起来？ 要怎么样才能只显示图片呢？求大神指导啊，还是没能很好的理解。。。
可能是图片呗覆盖了 可能根本都没显示出来
显示主要看适配器，你应该把adapter代码贴出来

public MyGridViewAdapter(Context pContext, String[] pStrs, int page) {
this.mContext = pContext;
mLists = new ArrayList<String>();
int i = page *PAGE_SIZE;
int end = i +PAGE_SIZE;
while ((i < pStrs.length) && (i < end)) {
mLists.add(pStrs[i]);
i++;
}
}
@Override
public int getCount() {
return mLists.size();
}

要看你R.layout.gridview__item这个布局怎么写了,如果只是文字就只用textview，只是图片就用imageview，图片加文字就textview和imageview配合起来用
