国际惯例,先上图:
代码比较简单,只需给listview设置Listener就OK,
当点击删除后,这里没有做提示,会直接删除,删除后应当给服务器发送一个删除好友的包,服务器端更新数据库中的数据。
然后客户端要做的就是更新下好友列表。
具体看代码吧:
private void setListViewListener() { listView.setOnItemClickListener(new OnItemClickListener(){ public void onItemClick(AdapterView<?> a, View v, int position,long l) { temp= (BuddyEntity) listView.getItemAtPosition(position); //打开聊天页面 Intent intent=new Intent(BuddyActivity.this,ChatActivity.class); intent.putExtra("avatar", temp.getAvatar()); intent.putExtra("account",temp.getAccount()); intent.putExtra("nick", temp.getNick()); startActivity(intent); } }); listView.setOnItemLongClickListener(new OnItemLongClickListener(){ public boolean onItemLongClick(AdapterView<?> arg0, View arg1,int position, long arg3) { temp= (BuddyEntity) listView.getItemAtPosition(position); listView.setOnCreateContextMenuListener(new OnCreateContextMenuListener(){ public void onCreateContextMenu(ContextMenu menu, View arg1, ContextMenuInfo arg2) { menu.setHeaderTitle("操作"); menu.add(0,0,0,"发起会话"); menu.add(0,1,0,"删除好友"); menu.add(0,2,0,"查看好友资料"); } }); return false; } }); } public boolean onContextItemSelected(MenuItem item) { switch(item.getItemId()){ case 0: //打开聊天页面 Intent intent=new Intent(BuddyActivity.this,ChatActivity.class); intent.putExtra("avatar", temp.getAvatar()); intent.putExtra("account",temp.getAccount()); intent.putExtra("nick", temp.getNick()); startActivity(intent); break; case 1: //向服务器发送一个删除好友的包 SendMessage.sendADbuddy(MoreActivity.me.getAccount(), temp.getAccount(), YQMessageType.DEL_BUDDY); //删除好友列表中的该好友 for(int i=0;i<buddyEntityList.size();i++){ if((buddyEntityList.get(i).getAccount())==temp.getAccount()){ buddyEntityList.remove(i); } } listView = (ListView) findViewById(R.id.listview); ba=new BuddyAdapter(this,buddyEntityList); listView.setAdapter(ba); break; case 2: // break; } return super.onContextItemSelected(item); }
