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);
-
- 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:
-
- 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:
-
- SendMessage.sendADbuddy(MoreActivity.me.getAccount(),
- temp.getAccount(),
- YQMessageType.DEL_BUDDY);
-
- 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);
- }
