Android_基于BMOB的聊天软件_添加好友

之前提过为什么要用BMOB，前段时间完成了用户的注册与登录，现在做添加好友功能，主要

参考BMOB官网

提供的资料。
主要流程就是，输入好友关键字，点击搜索，显示服务器上对应的搜索结果，用BMOB的好处就是不用自己建数据库啊，省了一个做前端还要处理后端的问题。
搜索代码如下：

private void serachFriend() {if(TextUtils.isEmpty(et_search.getText().toString())){Toast.makeText(getApplicationContext(), "查找内容不能为空哦。", Toast.LENGTH_LONG).show();return;}String searchName = et_search.getText().toString();progress = new ProgressDialog(AddFrindActivity.this);progress.setMessage("正在搜索...");progress.setCanceledOnTouchOutside(true);progress.show();searchService(searchName,progress);}private void searchService(String searchName, final ProgressDialog progress2) {// TODO Auto-generated method stubBmobQuery<MyUser> query = new BmobQuery<MyUser>();query.addWhereContains("username", searchName);query.findObjects(getApplicationContext(), new FindListener<MyUser>() {@Overridepublic void onSuccess(List<MyUser> arg0) {progress2.dismiss();
//              Toast.makeText(getApplicationContext(), arg0.size()+arg0.toString(), Toast.LENGTH_LONG).show();System.out.println(arg0.size()+arg0.toString());if(adapter == null){adapter = new AddFriendAdapter(getApplicationContext(), arg0);lv_search_friend.setAdapter(adapter);}else{adapter.notifyDataSetChanged();}}@Overridepublic void onError(int arg0, String arg1) {progress2.dismiss();Toast.makeText(getApplicationContext(), "查询失败：" + arg0 + "  , "+arg1, Toast.LENGTH_LONG).show();}});}

为显示搜索结果，采用ListView显示，为该ListView创建基于BaseAdapter的适配器，代码如下：

package com.ppl.get_loc.chat;import java.util.List;import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.Button;
import android.widget.TextView;
import android.widget.Toast;import com.loopj.android.image.SmartImageView;
import com.ppl.get_loc.R;public class AddFriendAdapter extends BaseAdapter {private Context mContext;private List<MyUser>data;private LayoutInflater layoutInflater;public AddFriendAdapter(Context mContext, List<MyUser> data) {super();this.mContext = mContext;this.data = data;layoutInflater = (LayoutInflater) mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);}@Overridepublic int getCount() {// TODO Auto-generated method stubreturn data.size();}@Overridepublic Object getItem(int arg0) {// TODO Auto-generated method stubreturn data.get(arg0);}@Overridepublic long getItemId(int arg0) {// TODO Auto-generated method stubreturn arg0;}@Overridepublic View getView(int position, View convertView, ViewGroup parent) {viewHolder holder = null;if(convertView == null){holder = new viewHolder();convertView = layoutInflater.inflate(R.layout.item_search_friend, null);holder.bt = (Button) convertView.findViewById(R.id.bt_search_add);holder.SIV = (SmartImageView) convertView.findViewById(R.id.SIV_search_avatar);holder.tv = (TextView) convertView.findViewById(R.id.tv_search_username);convertView.setTag(holder);}else{holder = (viewHolder)convertView.getTag();}MyUser tmpUserInfo = data.get(position);holder.SIV.setImageUrl(tmpUserInfo.getNick_URL_NET());holder.tv.setText(tmpUserInfo.getUsername());//点击添加按钮holder.bt.setOnClickListener(new OnClickListener() {@Overridepublic void onClick(View arg0) {// TODO Auto-generated method stubToast.makeText(mContext, "点击了添加按钮", Toast.LENGTH_LONG).show();}});return convertView;}private class viewHolder{private SmartImageView  SIV;private TextView tv;private Button bt;}
