Android的使用setNumStars变更执行期间星星让收视率的行为怪异 [英] Android using setNumStars to change stars during execution make the ratings act strange

问题描述

我使用rb.setNumStars（INT）改变恒星形成一个给定的默认值（比如5）到一个新的与App preferences（比如4）。在code进行确定，并刷新该片段后，我能看到的星星数目我设置任何整数的变化（条具有1的步长）。

I'm using rb.setNumStars(int) to change the stars form a given default value (say 5) to a new one with app preferences (say 4). The code performs Ok and after refresh the fragment, I can see the change in the stars number to any integer I set (the bar has a StepSize of 1).

问题是，当我尝试设置分级栏上，填充星不与评价值一致，我在陌生的地方取得联系，如果我碰拳头明星来了值，也就是说，我得到一个等级= 1，如果我摸到第二个，我还是有等级= 1和充满恒星是一个和第二个片段。如果我第二和第三颗星之间的联系，我得到等级= 2，我得到两个片段充满恒星。

The problem is that when I try to set the rating on that bar, the filled stars does not coincide with the rating value, and I have to touch in strange places to get come values, i.e. if I touch the fist star, I get a rating = 1, If I touch the second, I still have a rating = 1 and the filled stars are one and a fragment of the second. If I touch between the second and the third star, I get rating = 2 and I get two and a fragment filled stars.

想象一下：如果F是一个全明星，P是部分（但不是作为一个半星）和E是一个空的明星，如果我触碰第二个明星，而第二和第三，我得到的：

Imagine this: if F is a full star, P is a partial (but not as in a half star) and E is an empty star, if I touch the second star, and between the 2nd and the 3rd I get:

在fp E E等级= 1μF在fpë等级= 2

F P E E Rating = 1 F F P E rating = 2

如果我的价值回归5，酒吧的行为与预期，与充满恒星的评级相符。

If I return the value to 5, the bar behaves as expected, with the filled stars coinciding with the rating.

我不能插入图像，来解释这种行为，但我希望这是很清楚。

I can not insert images, to explain this behavior, but I hope it's clear enough.

有谁知道为什么会出现这种情况，如何纠正呢？

Does anybody knows why is this happening and how to correct it?

推荐答案

看来，我能回答我的问题。

It seems that I was able to answer my own question.

由于这是进度条的延伸，I'm猜测，当我改变数星星，一个进度条一直延伸到新的宽度，但保持其原始值，而不是反映了必须填写的部分。通过使用SETMAX差饷吧，我觉得I'm设置这一栏的新限制，所以，我改变数星星和最大值设置为数字，像这样的：

As this is an extension of the progress bar, I´m guessing that when I change the number of stars, a progress bar is stretching to the new width, but keeping it's original values, not reflecting the portion that must fill. By using setMax for the Rating Bar, I think I´m setting the new limits for this bar, so, I changed the number of stars and set the max value to that number, like this:

RatingBar rb = (RatingBar) view.findViewById(rbars[r]);
rb.setNumStars(Integer.valueOf(SP.getString(rchars[r], "3")));
rb.setMax(Integer.valueOf(SP.getString(rchars[r],"3")));
rb.setRating(2);

在这种方式的等级与填充分重合。

In this way the rating coincide with the filled stars.
