8.中間彈出框

9.具體使用
activity調用
@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,聊天記錄依然保留,確定要清空消息列表?") .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("發送給好友", ActionSheetDialog.SheetItemColor.Blue, new ActionSheetDialog.OnSheetItemClickListener() { @Override public void onClick(int which) { } }) .addSheetItem("轉載到空間相冊", ActionSheetDialog.SheetItemColor.Blue, new ActionSheetDialog.OnSheetItemClickListener() { @Override public void onClick(int which) { } }) .addSheetItem("上傳到群相冊", ActionSheetDialog.SheetItemColor.Blue, new ActionSheetDialog.OnSheetItemClickListener() { @Override public void onClick(int which) { } }) .addSheetItem("保存到手機", 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("查看聊天圖片", 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("請選擇操作") .setCancelable(false) .setCanceledOnTouchOutside(false) .addSheetItem("條目一", ActionSheetDialog.SheetItemColor.Blue, new ActionSheetDialog.OnSheetItemClickListener() { @Override public void onClick(int which) { } }) .addSheetItem("條目二", 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("退出當前賬號") .setMsg("再連續登陸15天,就可變身為QQ達人。退出QQ可能會使你現有記錄歸零,確定退出?") .setPositiveButton("確認退出", 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("你現在無法接收到新消息提醒。請到系統-設置-通知中開啟消息提醒") .setNegativeButton("確定", new View.OnClickListener() { @Override public void onClick(View v) { } }).show(); break; default: break; } }
