我的 NavDrawerListAdapter
    import java.util.ArrayList;

import android.app.Activity;
import android.content.Context;
import android.graphics.Typeface;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.ImageView;
import android.widget.TextView;

import com.kmcpesh.Pharmadrugsclassification.model.NavDrawerItem;
import com.kmcpesh.Pharmadrugsclassification.R;

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);
String font="fonts/walt.tff";
Typeface text=Typeface.createFromAsset(txtTitle.getContext().getAssets(), "fonts/walt.ttf");
txtTitle.setTypeface(text);
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;
}

}

我的 NavDraweritem.java
    public class NavDrawerItem {

private String title;
private int icon;
private String count = "0";
// boolean to set visiblity of the counter
private boolean isCounterVisible = false;

public NavDrawerItem(){}

public NavDrawerItem(String title, int icon){
this.title = title;
this.icon = icon;
}

public NavDrawerItem(String title, int icon, boolean isCounterVisible, String count){
this.title = title;
this.icon = icon;
this.isCounterVisible = isCounterVisible;
this.count = count;
}

public String getTitle(){
return this.title;
}

public int getIcon(){
return this.icon;
}

public String getCount(){
return this.count;
}

public boolean getCounterVisibility(){
return this.isCounterVisible;
}

public void setTitle(String title){
this.title = title;
}

public void setIcon(int icon){
this.icon = icon;
}

public void setCount(String count){
this.count = count;
}

public void setCounterVisibility(boolean isCounterVisible){
this.isCounterVisible = isCounterVisible;
}
}

这是我的 activity_main.xml
    <android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<include layout="@layout/header" />

<TextView
android:id="@+id/label"
style="@android:style/TextAppearance.Large"
android:layout_width="fill_parent"
android:layout_height="wrap_content" />

<!-- Framelayout to display Fragments -->
<FrameLayout
android:id="@+id/frame_container"
android:layout_width="match_parent"
android:layout_height="match_parent" />

<!-- Listview to display slider menu -->
<ListView
android:id="@+id/list_slidermenu"
android:layout_width="250dp"
android:layout_height="match_parent"
android:layout_gravity="start"
android:choiceMode="singleChoice"
android:divider="@color/list_divider"
android:dividerHeight="0.2dp"
android:listSelector="@drawable/list_selector"
android:background="@color/list_background"/>
</android.support.v4.widget.DrawerLayout>

这是我的 list_item.xml
  <?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="48dp"
android:background="@drawable/list_selector">

<ImageView
android:id="@+id/icon"
android:layout_width="25dp"
android:layout_height="50dp"
android:layout_alignParentLeft="true"
android:layout_marginLeft="12dp"
android:layout_marginRight="12dp"
android:contentDescription="@string/desc_list_item_icon"
android:src="@drawable/ic_home"
android:layout_centerVertical="true" />

<TextView
android:id="@+id/title"
android:layout_width="wrap_content"
android:layout_height="40dp"
android:layout_toRightOf="@id/icon"
android:textColor="@color/list_item_title"
android:gravity="center_vertical"
android:paddingRight="40dp"/>

<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/counter_text_color"/>

</RelativeLayout>

最后是我的 header.xml
    <?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<TextView
android:id="@+id/header"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textColor="@color/list_divider"
/>

</LinearLayout>
