Android自定义RatingBar评分控件

RatingBar是基于SeekBar（拖动条）和ProgressBar（状态条）的扩展，用星形来显示等级评定！

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">

    <item
        android:id="@android:id/background"
        android:drawable="@drawable/collect">
    </item>
    <item
        android:id="@android:id/secondaryProgress"
        android:drawable="@drawable/collect">
    </item>
    <item
        android:id="@android:id/progress"
        android:drawable="@drawable/collected">
    </item>

</layer-list>

 <!-- 评分条样式 -->
    <style name="roomRatingBar" parent="@android:style/Widget.RatingBar">
        <item name="android:progressDrawable">@drawable/star_seletor</item>
        <item name="android:minHeight">45dp</item>
        <item name="android:maxHeight">45dp</item>
    </style>

    <style name="ratingbar_style" parent="roomRatingBar">
        <item name="android:layout_width">wrap_content</item>
        <item name="android:layout_height">wrap_content</item>
        <item name="android:spacing">@dimen/space_10</item>
        <item name="android:stepSize">1</item>
        <item name="android:numStars">5</item>
    </style>

如上给ratingbar设置了style后星星”流泪“、”有脚“，解决办法如下：

private int getScroeHeight() {
        int scroeHeight = 0;
        try {
            Bitmap bmp = BitmapFactory.decodeResource(this.getResources(), R.drawable.collect);
            scroeHeight = bmp.getHeight();
        } catch (Exception e) {
            e.printStackTrace();
        }
        return scroeHeight;
    }

 private void setRatingBar(final int positon, int scroeHeight, RatingBar mRatingBar) {
        //在需要的地方设置LayoutParams  记得图片只需要初始化一次就可以了。
        if (scroeHeight != 0) {
            LinearLayout.LayoutParams llp = (LinearLayout.LayoutParams) mRatingBar.getLayoutParams();
            llp.width = -2;// 包裹内容
            llp.height = scroeHeight;
            mRatingBar.setLayoutParams(llp);
        }
        mRatingBar.setOnRatingBarChangeListener(new RatingBar.OnRatingBarChangeListener() {
            public void onRatingChanged(RatingBar ratingBar, float rating, boolean fromUser) {
                scoreArray[positon] = (int) rating;
            }
        });
    }
