我可以上传我的代码，但我甚至不知道在哪里查找错误。我不确定它在谈论哪个xml文件。任何帮助，将不胜感激。错误如下：

我只是想让支持库用于基本的导航抽屉和操作栏布局。再次感谢。
所以看起来问题就在于你的信息。我认为原因是，这段代码可能没有使用相同的支持库导入。第47行正在进行膨胀。
package io.uprint.android.adapter;
import io.uprint.android.R;
import io.uprint.android.model.NavDrawerItem;
import java.util.ArrayList;
import android.app.Activity;
import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.ImageView;
import android.widget.TextView;
public class NavDrawerListAdapter extends BaseAdapter {
private Context context;
private ArrayList<NavDrawerItem> navDrawerItems;
public NavDrawerListAdapter(Context context, ArrayList<NavDrawerItem> navDrawerItems){
this.context = context;
this.navDrawerItems = navDrawerItems;
}
@Override
public int getCount() {
return navDrawerItems.size();
}
@Override
public Object getItem(int position) {
return navDrawerItems.get(position);
}
@Override
public long getItemId(int position) {
return position;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
if (convertView == null) {
LayoutInflater mInflater = (LayoutInflater)
context.getSystemService(Activity.LAYOUT_INFLATER_SERVICE);
convertView = mInflater.inflate(R.layout.drawer_list_item, null);
}
ImageView imgIcon = (ImageView) convertView.findViewById(R.id.icon);
TextView txtTitle = (TextView) convertView.findViewById(R.id.title);
TextView txtCount = (TextView) convertView.findViewById(R.id.counter);
imgIcon.setImageResource(navDrawerItems.get(position).getIcon());
txtTitle.setText(navDrawerItems.get(position).getTitle());
// displaying count
// check whether it set visible or not
if(navDrawerItems.get(position).getCounterVisibility()){
txtCount.setText(navDrawerItems.get(position).getCount());
}else{
// hide the counter view
txtCount.setVisibility(View.GONE);
}
return convertView;
}
}
下面是布局中的xml文件

不同文件中的属性值 attrs.xml
<declare-styleable name="Theme">

<!-- The preferred TextAppearance for the primary text of small list items. -->
<attr name="uprint_textAppearanceListItemSmall" format="reference" />
</declare-styleable>
styles.xml值v11：
<style name="AppBaseTheme" parent="Theme.Light">
<!-- API 11 theme customizations can go here. -->
<!-- Implementation of attributes needed for the navigation drawer as the default implementation is based on API-14. -->
<item name="uprint_listPreferredItemHeightSmall">48dip</item>

答案 0 :(得分：0)
您传递给 NavDrawerListAdapter 的上下文？ 我在Gingerbread + AppCompat上遇到了类似的问题，因为我使用的是Application上下文而不是Activity上下文。
