在主布局中写出DrawerLayout布局，在布局中在写一个listview
<ListView    android:id="@+id/lv"    android:layout_width="240sp"    android:layout_height="match_parent"    android:layout_gravity="start"    android:choiceMode="singleChoice"    android:divider="#f00"    android:dividerHeight="1dp"    android:background="#fff"></ListView>在Activity中，CelaBean是封装的Bean类private DrawerLayout activity_main;private ListView lv;private List<CelaBean> beanList;activity_main = (DrawerLayout) findViewById(R.id.activity_main);lv = (ListView) findViewById(R.id.lv);beanList = new ArrayList<CelaBean>();beanList.add(new CelaBean(R.mipmap.ic_launcher,"QQ"));beanList.add(new CelaBean(R.mipmap.ic_launcher,"我的"));beanList.add(new CelaBean(R.mipmap.ic_launcher,"你的"));beanList.add(new CelaBean(R.mipmap.ic_launcher,"他的"));CelaAdapter dapter = new CelaAdapter(beanList,MainActivity.this);lv.setAdapter(dapter);lv.setOnItemClickListener(new AdapterView.OnItemClickListener() {    @Override    public void onItemClick(AdapterView<?> parent, View view, int position, long id) {        activity_main.closeDrawer(lv);    }});

适配器

public class CelaAdapter extends BaseAdapter{    private List<CelaBean> beanList;    private Context context;    private LayoutInflater inflater;    public CelaAdapter(List<CelaBean> beanList, Context context) {        this.beanList = beanList;        this.context = context;        inflater = LayoutInflater.from(context);    }    @Override    public int getCount() {        return beanList.size();    }    @Override    public Object getItem(int position) {        return beanList.get(position);    }    @Override    public long getItemId(int position) {        return position;    }    @Override    public View getView(int position, View convertView, ViewGroup parent) {        ViewHoder hoder = new ViewHoder();        if(convertView==null){            convertView = inflater.inflate(R.layout.cela,null);            hoder.image1 = (ImageView) convertView.findViewById(R.id.image1);            hoder.tv = (TextView) convertView.findViewById(R.id.tv);            convertView.setTag(hoder);        }else{            hoder = (ViewHoder) convertView.getTag();        }        hoder.image1.setImageResource(beanList.get(position).getImage());        hoder.tv.setText(beanList.get(position).getName());        return convertView;    }    class ViewHoder{        ImageView image1;        TextView tv;    }}

适配器对应的子XML

<ImageView    android:id="@+id/image1"    android:layout_width="wrap_content"    android:layout_height="wrap_content" /><TextView    android:id="@+id/tv"    android:layout_width="wrap_content"    android:layout_height="wrap_content" />
