以下行发生异常：
convertView = mInflater.inflate(R.layout.item_drawer, null);
异常所引用的类[Adapter_NavDrawerList.java]是：
package com.tsirigotis.myradio.library;
import java.util.ArrayList;
import com.tsirigotis.myradio.R;
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 Adapter_NavDrawerList extends BaseAdapter {
private Context context;
private ArrayList<Object_NavDrawer> navDrawerItems;
public Adapter_NavDrawerList(Context context, ArrayList<Object_NavDrawer> 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.item_drawer, 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;
}
}
和布局[item_drawer.xml]
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="48dp"
android:background="@drawable/list_selector"
xmlns:android="http://schemas.android.com/apk/res/android">
<ImageView
android:id="@+id/icon"
android:layout_width="25dp"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_marginLeft="12dp"
android:layout_marginRight="12dp"
android:src="@drawable/ic_drawer"
android:layout_centerVertical="true" />
<TextView
android:id="@+id/title"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_toRightOf="@id/icon"
android:minHeight="?android:attr/listPreferredItemHeightSmall"
android:textAppearance="?android:attr/textAppearanceListItemSmall"
android:gravity="center_vertical"
android:paddingRight="40dp"
android:textColor="?attr/list_item_title"
android:textSize="14sp" />
<TextView android:id="@+id/counter"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="@drawable/counter_bg"
android:layout_alignParentRight="true"
android:layout_centerVertical="true"
android:layout_marginRight="8dp"
android:textColor="@color/holo_counter_text_color"/>
</RelativeLayout>
如果有人可以帮助我，我会很感激。谢谢。忘了提Minsdk 16

您是否检查过所有资源？堆栈跟踪清楚地表明某些元素无法从XML实例化，并且您没有使用任何自定义视图，因此必须是资源。
