9.具体使用
activity调用
@Override public void onClick(View v) { switch (v.getId()) { case R.id.click: // TODO 18/03/16 new ActionSheetDialog(this) .builder() .setTitle("清空消息列表后,聊天记录依然保留,确定要清空消息列表?") .setCancelable(false) .setCanceledOnTouchOutside(false) .addSheetItem("清空消息列表", ActionSheetDialog.SheetItemColor.Red , new ActionSheetDialog.OnSheetItemClickListener() { @Override public void onClick(int which) { } }).show(); break; case R.id.iamge:// TODO 18/03/16 new ActionSheetDialog(this) .builder() .setCancelable(false) .setCanceledOnTouchOutside(false) .addSheetItem("发送给好友", ActionSheetDialog.SheetItemColor.Blue, new ActionSheetDialog.OnSheetItemClickListener() { @Override public void onClick(int which) { } }) .addSheetItem("转载到空间相册", ActionSheetDialog.SheetItemColor.Blue, new ActionSheetDialog.OnSheetItemClickListener() { @Override public void onClick(int which) { } }) .addSheetItem("上传到群相册", ActionSheetDialog.SheetItemColor.Blue, new ActionSheetDialog.OnSheetItemClickListener() { @Override public void onClick(int which) { } }) .addSheetItem("保存到手机", ActionSheetDialog.SheetItemColor.Blue, new ActionSheetDialog.OnSheetItemClickListener() { @Override public void onClick(int which) { } }) .addSheetItem("收藏", ActionSheetDialog.SheetItemColor.Blue, new ActionSheetDialog.OnSheetItemClickListener() { @Override public void onClick(int which) { } }) .addSheetItem("查看聊天图片", ActionSheetDialog.SheetItemColor.Blue, new ActionSheetDialog.OnSheetItemClickListener() { @Override public void onClick(int which) { } }).show(); break; case R.id.ctrol:// TODO 18/03/16 new ActionSheetDialog(this) .builder() .setTitle("请选择操作") .setCancelable(false) .setCanceledOnTouchOutside(false) .addSheetItem("条目一", ActionSheetDialog.SheetItemColor.Blue, new ActionSheetDialog.OnSheetItemClickListener() { @Override public void onClick(int which) { } }) .addSheetItem("条目二", ActionSheetDialog.SheetItemColor.Blue, new ActionSheetDialog.OnSheetItemClickListener() { @Override public void onClick(int which) { } }).show(); break; case R.id.login:// TODO 18/03/16 new AlertDialog(this).builder().setTitle("退出当前账号") .setMsg("再连续登陆15天,就可变身为QQ达人。退出QQ可能会使你现有记录归零,确定退出?") .setPositiveButton("确认退出", new View.OnClickListener() { @Override public void onClick(View v) { } }).setNegativeButton("取消", new View.OnClickListener() { @Override public void onClick(View v) { } }).show(); break; case R.id.msg:// TODO 18/03/16 new AlertDialog(this).builder() .setMsg("你现在无法接收到新消息提醒。请到系统-设置-通知中开启消息提醒") .setNegativeButton("确定", new View.OnClickListener() { @Override public void onClick(View v) { } }).show(); break; default: break; } }
