评级栏的星星之间的间距？

Question

我可以在星星之间设置间距吗？多数民众赞成我的评级栏:

ratingBar = (RatingBar) inflater.inflate(R.layout.ratingbar, null);
ratingBar.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));

布局:

<?xml version="1.0" encoding="utf-8"?>
<RatingBar xmlns:android="http://schemas.android.com/apk/res/android"
    style="@style/myStyle" android:layout_alignParentRight="true"
    android:layout_height="19dp" android:layout_width="wrap_content"
    android:numStars="5">
</RatingBar>

风格:

 <style name="myStyle" parent="@android:style/Widget.RatingBar">
    <item name="android:progressDrawable">@drawable/android_r2_ratingstar_yellow</item>
    <item name="android:indeterminateDrawable">@drawable/android_r2_ratingstar_grey</item>
 </style>

谢谢,欢呼

您必须将填充添加到 png 本身。虽然有一种称为“Inset Drawable”（http://developer.android.com/guide/topics/resources/drawable-resource.html#Inset）的东西，您可以将您的可绘制对象包装到其中，但“tileify”的代码（如 android 源代码中所述）不处理可绘制对象是插入可绘制对象的情况，因此不会平铺图像。

这是tilefy方法（在ProgressBar.java中，它是RatingBar.java的祖先：https://gist.github.com/CyanogenMod/android_frameworks_base/blob/gingerbread/core/java/android/widget/ProgressBar.java）

private Drawable tileify(Drawable drawable, boolean clip) {

    if (drawable instanceof LayerDrawable) {
        LayerDrawable background = (LayerDrawable) drawable;
        final int N = background.getNumberOfLayers();
        Drawable[] outDrawables = new Drawable[N];

        for (int i = 0; i < N; i++) {
            int id = background.getId(i);
            outDrawables[i] = tileify(background.getDrawable(i),
                    (id == R.id.progress || id == R.id.secondaryProgress));
        }

        LayerDrawable newBg = new LayerDrawable(outDrawables);

        for (int i = 0; i < N; i++) {
            newBg.setId(i, background.getId(i));
        }

        return newBg;

    } else if (drawable instanceof StateListDrawable) {
        StateListDrawable in = (StateListDrawable) drawable;
        StateListDrawable out = new StateListDrawable();
        int numStates = in.getStateCount();
        for (int i = 0; i < numStates; i++) {
            out.addState(in.getStateSet(i), tileify(in.getStateDrawable(i), clip));
        }
        return out;

    } else if (drawable instanceof BitmapDrawable) {
        final Bitmap tileBitmap = ((BitmapDrawable) drawable).getBitmap();
        if (mSampleTile == null) {
            mSampleTile = tileBitmap;
        }

        final ShapeDrawable shapeDrawable = new ShapeDrawable(getDrawableShape());

        final BitmapShader bitmapShader = new BitmapShader(tileBitmap,
                Shader.TileMode.REPEAT, Shader.TileMode.CLAMP);
        shapeDrawable.getPaint().setShader(bitmapShader);

        return (clip) ? new ClipDrawable(shapeDrawable, Gravity.LEFT,
                ClipDrawable.HORIZONTAL) : shapeDrawable;
    }

    return drawable;
}
