用就簡單了:
new IosAlertDialog(LikeIosDialogActivity.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();

可以這樣用：
new IosAlertDialog(LikeIosDialogActivity.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();

用法也比較簡單，很靈活：
new ActionSheetDialog(LikeIosDialogActivity.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(true)//設置點擊其他地方與返回是否消失 true為消失
.addSheetItem("清空消息列表", ActionSheetDialog.SheetItemColor.Red,
new ActionSheetDialog.OnSheetItemClickListener() {
@Override
public void onClick(int which) {
}
}).show();
也可以這樣：
new ActionSheetDialog(LikeIosDialogActivity.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,
