2）获取传递过来的数据
// 获取传递过来的参数
private void getData() {
// 获取传递过来的群id
String groupId = getIntent().getStringExtra(Constant.GROUP_ID);
// 校验
if (groupId == null) {
finish();
return;
} else {
// 获取群信息
mGroup = EMClient.getInstance().groupManager().getGroup(groupId);
}
}
3）初始化button按钮的显示
// 初始化按钮的显示
private void initButtonDisplay() {
//显示
// 判断是否是群主
if (EMClient.getInstance().getCurrentUser().equals(mGroup.getOwner())) {
// 更新显示
btn_exit_group.setText("解散群");
// 解散群的点击事件
btn_exit_group.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Model.getInstace().getGolbalThreadPool().execute(new Runnable() {
@Override
public void run() {
// 联网
try {
// 联网成功
EMClient.getInstance().groupManager().destroyGroup(mGroup.getGroupId());
// 发送解散群广播
exitGroupBroadCast();
// 提示
runOnUiThread(new Runnable() {
@Override
public void run() {
Toast.makeText(GroupDetailActivity.this, "解散群成功", Toast.LENGTH_SHORT).show();
// 销毁当前页面
finish();
}
});
} catch (HyphenateException e) {
e.printStackTrace();
// 提示
runOnUiThread(new Runnable() {
@Override
public void run() {
Toast.makeText(GroupDetailActivity.this, "解散群失败", Toast.LENGTH_SHORT).show();
}
});
}
}
});
}
});
} else {// 群成员
btn_exit_group.setText("退群");
// 退群按钮点击事件
btn_exit_group.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// 联网
Model.getInstace().getGolbalThreadPool().execute(new Runnable() {
@Override
public void run() {
try {
EMClient.getInstance().groupManager().leaveGroup(mGroup.getGroupId());
// 发送广播
exitGroupBroadCast();
// 提示
runOnUiThread(new Runnable() {
@Override
public void run() {
Toast.makeText(GroupDetailActivity.this, "退群成功", Toast.LENGTH_SHORT).show();
// 销毁当前页面
finish();
}
});
} catch (HyphenateException e) {
e.printStackTrace();
runOnUiThread(new Runnable() {
@Override
public void run() {
Toast.makeText(GroupDetailActivity.this, "退群失败", Toast.LENGTH_SHORT).show();
}
});
}
}
});
}
});
}
}
4）退群和解散群
发送退群广播
// 解散群和退群广播
private void exitGroupBroadCast() {
// 发送广播
Intent intent = new Intent(Constant.EXIT_GROUP);
// 传递群id参数
intent.putExtra(Constant.GROUP_ID, mGroup.getGroupId());
// 发送
mLBM.sendBroadcast(intent);
}
5）初始化Gridview
// 初始化gridview
private void initGridview() {
// 你是群主 或者 你这个群是公开 你就可以添加和删除群成员
boolean mIsCanModify = EMClient.getInstance().getCurrentUser().equals(mGroup.getOwner()) || mGroup.isPublic();
// 创建适配器
mGroupDetailAdapter = new GroupDetailAdapter(GroupDetailActivity.this, mIsCanModify, mOnGroupDetailListener);
// 添加到gridview
gv_member_list.setAdapter(mGroupDetailAdapter);
}
6）GridView适配器
public class GroupDetailAdapter extends BaseAdapter {
private Context mContext;
private boolean mIsCanModify; // 表示可以添加和删除好友
private boolean mIsDeleteModel; // 是否是删除模式 true:删除模式 false:非删除模式
private List<UserInfo> mUsers = new ArrayList<>();
private OnGroupDetailListener mOnGroupDetailListener;
private final String mCurrentUser;
public GroupDetailAdapter(Context context, boolean isCanModify, OnGroupDetailListener onGroupDetailListener) {
mContext = context;
mIsCanModify = isCanModify;
mOnGroupDetailListener = onGroupDetailListener;
mCurrentUser = EMClient.getInstance().getCurrentUser();
}
private void initUsers() {
UserInfo add = new UserInfo("add");
UserInfo delete = new UserInfo("delete");
mUsers.add(delete);
mUsers.add(0, add);
}
// 刷新的方法
public void refresh(List<UserInfo> users) {
// 校验
if (users != null && users.size() >= 0) {
mUsers.clear();
initUsers();
mUsers.addAll(0, users);
}
// 刷新页面
notifyDataSetChanged();
}
// 获取当前的模式
public boolean ismIsDeleteModel() {
return mIsDeleteModel;
}
// 设置当前的模式
public void setmIsDeleteModel(boolean mIsDeleteModel) {
this.mIsDeleteModel = mIsDeleteModel;
}
@Override
public int getCount() {
return mUsers == null ? 0 : mUsers.size();
}
@Override
public Object getItem(int position) {
return mUsers.get(position);
}
@Override
public long getItemId(int position) {
return position;
}
@Override
public View getView(final int position, View convertView, ViewGroup parent) {
// 创建或获取viewHolder
ViewHolder holder = null;
if (convertView == null) {
holder = new ViewHolder();
convertView = View.inflate(mContext, R.layout.item_group_detail, null);
holder.photo = (ImageView) convertView.findViewById(R.id.iv_member_photo);
holder.name = (TextView) convertView.findViewById(R.id.tv_member_name);
holder.delete = (ImageView) convertView.findViewById(R.id.iv_member_delete);
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
if (position != getCount() - 1 && position != getCount() - 2) {
if (holder.name.getVisibility() == View.INVISIBLE) {
holder = new ViewHolder();
convertView = View.inflate(mContext, R.layout.item_group_detail, null);
holder.photo = (ImageView) convertView.findViewById(R.id.iv_member_photo);
holder.name = (TextView) convertView.findViewById(R.id.tv_member_name);
holder.delete = (ImageView) convertView.findViewById(R.id.iv_member_delete);
convertView.setTag(holder);
}
}
}
// 显示数据
// 判断是否有修改的权限
if (mIsCanModify) {// 修改模式
// 1 监听事件
if (position == getCount() - 1) {// 减号位置
holder.photo.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// 如果当前是非删除模式
if (!mIsDeleteModel) {
// 修改为删除模式
mIsDeleteModel = true;
// 更新显示
notifyDataSetChanged();
}
}
});
} else if (position == getCount() - 2) {// 加号位置
holder.photo.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// 逻辑复杂 不再这操作
mOnGroupDetailListener.onAddMembers();
}
});
} else {// 群成员的点击事件
holder.delete.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// 不再这操作
mOnGroupDetailListener.onDeleteMember(mUsers.get(position));
}
});
}
// 2 显示布局
if (position == getCount() - 1) {// 减号
if (mIsDeleteModel) {
convertView.setVisibility(View.INVISIBLE);
} else {
convertView.setVisibility(View.VISIBLE);
// 设置数据
holder.photo.setImageResource(R.drawable.em_smiley_minus_btn_pressed);
holder.delete.setVisibility(View.GONE);
holder.name.setVisibility(View.INVISIBLE);
}
} else if (position == getCount() - 2) {// 加号
if (mIsDeleteModel) {
convertView.setVisibility(View.INVISIBLE);
} else {
convertView.setVisibility(View.VISIBLE);
holder.photo.setImageResource(R.drawable.em_smiley_add_btn_pressed);
holder.delete.setVisibility(View.GONE);
holder.name.setVisibility(View.INVISIBLE);
}
} else {
// 获取当前item数据
UserInfo user = mUsers.get(position);
convertView.setVisibility(View.VISIBLE);
holder.name.setVisibility(View.VISIBLE);
holder.photo.setVisibility(View.VISIBLE);
holder.name.setText(user.getName());
holder.photo.setImageResource(R.drawable.em_default_avatar);
if (mIsDeleteModel && !mCurrentUser.equals(user.getHxId())) {
// 布局设置
holder.delete.setVisibility(View.VISIBLE);
} else {
holder.delete.setVisibility(View.GONE);
}
}
} else {
// 展示数据
if (position == getCount() - 1 || position == getCount() - 2) {
convertView.setVisibility(View.INVISIBLE);
} else {
convertView.setVisibility(View.VISIBLE);
// 获取当前item数据
UserInfo userInfo = mUsers.get(position);
holder.name.setText(userInfo.getName());
holder.photo.setImageResource(R.drawable.em_default_avatar);
holder.delete.setVisibility(View.GONE);
}
}
// 返回view
return convertView;
}
static class ViewHolder {
TextView name;
ImageView photo;
ImageView delete;
}
public interface OnGroupDetailListener {
// 添加成员的方法
void onAddMembers();
// 删除群成员方法
void onDeleteMember(UserInfo user);
}
}
7）从环信服务器获取所有群成员
private void getMembersFromHxServer() {
Modle.getInstance().getGlobalThreadPool().execute(new Runnable() {
@Override
public void run() {
try {
EMGroup groupFromServer = EMClient.getInstance().groupManager().getGroupFromServer(mGroup.getGroupId());
List<String> members = groupFromServer.getMembers();
if(members != null && members.size() >=0) {
mUserss = new ArrayList<UserInfo>();
for (String member:members){
UserInfo userInfo = new UserInfo(member);
mUserss.add(userInfo);
}
}
runOnUiThread(new Runnable() {
@Override
public void run() {
mGroupDetailAdapter.refresh(mUserss);
// Toast.makeText(GroupDetailAcitivity.this, "加载成功", Toast.LENGTH_SHORT).show();
}
});
} catch (HyphenateException e) {
e.printStackTrace();
}
}
});
}
8）GridView适配器回调接口
（1）删除群成员
Model.getInstace().getGolbalThreadPool().execute(new Runnable() {
@Override
public void run() {
try {
// 从环信服务器中删除该成员
EMClient.getInstance().groupManager().removeUserFromGroup(group.getGroupId(),user.getHxId() );
// 从环信服务器再次获取群成员，并刷新页面
getUsersFromHxServer();
runOnUiThread(new Runnable() {
@Override
public void run() {
Toast.makeText(GroupDetailActivity.this, "删除该成员成功", Toast.LENGTH_SHORT).show();
}
});
} catch (HyphenateException e) {
e.printStackTrace();
runOnUiThread(new Runnable() {
@Override
public void run() {
Toast.makeText(GroupDetailActivity.this, "删除该成员失败", Toast.LENGTH_SHORT).show();
}
});
}
}
});
（2）添加群成员
public void onAddMembers() {
// 跳转到选择联系人页面
Intent intent = new Intent(GroupDetailActivity.this, PickContactsActivity.class);
intent = intent.putExtra(Constant.GROUP_ID, group.getGroupId());
startActivityForResult(intent, 0);
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if(resultCode == RESULT_OK) {
// 获取返回的联系人信息
final String[] memberses = data.getStringArrayExtra("members");
Model.getInstace().getGolbalThreadPool().execute(new Runnable() {
@Override
public void run() {
try {
// 添加群成员到该群组
EMClient.getInstance().groupManager().addUsersToGroup(group.getGroupId(), memberses);
// 访问服务器刷新页面
// getUsersFromHxServer();
runOnUiThread(new Runnable() {
@Override
public void run() {
Toast.makeText(GroupDetailActivity.this, "发送加入该群邀请成功", Toast.LENGTH_SHORT).show();
}
});
} catch (HyphenateException e) {
e.printStackTrace();
runOnUiThread(new Runnable() {
@Override
public void run() {
Toast.makeText(GroupDetailActivity.this, "发送加入该群邀请失败", Toast.LENGTH_SHORT).show();
}
});
}
}
});
}
}
