View layout_head = getLayoutInflater().inflate(R.layout.layout_head_search, null);mlistview.addHeaderView(layout_head);

用于搜索。

<?xml version="1.0" encoding="utf-8"?><LinearLayoutxmlns:android="http://schemas.android.com/apk/res/android"android:layout_width="fill_parent"android:layout_height="wrap_content"android:orientation="vertical">   <TextViewandroid:id="@+id/txt_search"android:layout_width="fill_parent"android:layout_height="33dp"android:drawableLeft="@drawable/search_icon"android:background="@drawable/search_ba"android:layout_margin="15dp"android:paddingLeft="20dp"android:text="@string/search"android:drawablePadding="10dp"android:textColor="@color/black1"android:gravity="center|left"android:singleLine="true" />

</LinearLayout>

通过服务器获取群聊列表：

@Overrideprotected void initView() {try {        List<EMGroup> grouplist = EMGroupManager.getInstance().getGroupsFromServer();if (grouplist != null && grouplist.size() > 0) {mlistview.setAdapter(new MyGroupAdpter(this, grouplist));        } else {            TextView txt_nodata = (TextView) findViewById(R.id.txt_nochat);            txt_nodata.setText("暂时没有群聊");            txt_nodata.setVisibility(View.VISIBLE);        }    } catch (EaseMobException e) {        e.printStackTrace();    }}

群聊适配器：

public class MyGroupAdpter extends BaseAdapter {protected Context context;private List<EMGroup> grouplist;

public MyGroupAdpter(Context ctx, List<EMGroup> grouplist) {context = ctx;this.grouplist = grouplist;    }

@Overridepublic int getCount() {return grouplist.size();    }

@Overridepublic Object getItem(int position) {return null;    }

@Overridepublic long getItemId(int position) {return position;    }

@Overridepublic View getView(int position, View convertView, ViewGroup parent) {if (convertView == null) {            convertView = LayoutInflater.from(context).inflate(R.layout.layout_item_mygroup, parent, false);        }final EMGroup group = grouplist.get(position);        ImageView img_avar = ViewHolder.get(convertView, R.id.img_photo);        TextView txt_name = ViewHolder.get(convertView, R.id.txt_name);        img_avar.setImageResource(R.drawable.defult_group);        txt_name.setText(group.getGroupName());        convertView.setOnClickListener(new View.OnClickListener() {

@Overridepublic void onClick(View v) {                Intent intent = new Intent(context, ChatActivity.class);                intent.putExtra(Constants.NAME, group.getGroupName());                intent.putExtra(Constants.TYPE, ChatActivity.CHATTYPE_GROUP);                intent.putExtra(Constants.GROUP_ID, group.getGroupId());context.startActivity(intent);            }        });return convertView;    }}

子项布局文件：

<?xml version="1.0" encoding="utf-8"?><LinearLayoutxmlns:android="http://schemas.android.com/apk/res/android"android:layout_width="fill_parent"android:layout_height="wrap_content"android:orientation="vertical">
