我创建了一个自定义评分栏,它可以有5种不同的颜色,并且具有矩形条,点下面有星星。这里是什么样子:姜饼设备上的自定义评分栏
我使用的几个地方这种观点,一切都在Android 4.0+确定。但姜饼我有一些问题。下面是视图类代码:
public class KrinsenRating extends RelativeLayout {
private TextView mRanking;
private RatingBar mStars;
public KrinsenRating(Context context, AttributeSet attrs) {
super(context, attrs);
LayoutInflater layoutInflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
layoutInflater.inflate(R.layout.krinsen_rating, this);
loadViews();
}
public KrinsenRating(Context context) {
super(context);
loadViews();
}
private void loadViews() {
mRanking = (TextView) findViewById(R.id.ranking_bar_position);
mStars = (RatingBar) findViewById(R.id.ranking_bar);
}
public void setRating(long rating){
RatingConverter rc = new RatingConverter(rating);
Bitmap bmp_empty = ((BitmapDrawable) getResources().getDrawable(R.drawable.star_empty)).getBitmap();
Bitmap bmp_half = null;
Bitmap bmp_full = null;
switch (rc.getColor()) {
case 1:
bmp_half = ((BitmapDrawable) getResources().getDrawable(R.drawable.star_half1)).getBitmap();
bmp_full = ((BitmapDrawable) getResources().getDrawable(R.drawable.star_full1)).getBitmap();
mRanking.setBackgroundColor(getResources().getColor(R.color.ranking1));
break;
case 2:
bmp_half = ((BitmapDrawable) getResources().getDrawable(R.drawable.star_half2)).getBitmap();
bmp_full = ((BitmapDrawable) getResources().getDrawable(R.drawable.star_full2)).getBitmap();
mRanking.setBackgroundColor(getResources().getColor(R.color.ranking2));
break;
case 3:
bmp_half = ((BitmapDrawable) getResources().getDrawable(R.drawable.star_half3)).getBitmap();
bmp_full = ((BitmapDrawable) getResources().getDrawable(R.drawable.star_full3)).getBitmap();
mRanking.setBackgroundColor(getResources().getColor(R.color.ranking3));
break;
case 4:
bmp_half = ((BitmapDrawable) getResources().getDrawable(R.drawable.star_half4)).getBitmap();
bmp_full = ((BitmapDrawable) getResources().getDrawable(R.drawable.star_full4)).getBitmap();
mRanking.setBackgroundColor(getResources().getColor(R.color.ranking4));
break;
case 5:
bmp_half = ((BitmapDrawable) getResources().getDrawable(R.drawable.star_half5)).getBitmap();
bmp_full = ((BitmapDrawable) getResources().getDrawable(R.drawable.star_full5)).getBitmap();
mRanking.setBackgroundColor(getResources().getColor(R.color.ranking5));
break;
}
mStars.setProgressDrawable(GUI.buildRatingBarDrawables(new Bitmap[]{bmp_empty, bmp_half, bmp_full}));
mStars.setRating(rc.getRealRating());
mRanking.setText(rating + "");
}
}
此行是混乱的:mStars.setProgressDrawable(GUI.buildRatingBarDrawables(new Bitmap[]{bmp_empty, bmp_half, bmp_full}));
,但我在后setProgressDrawable()
调用(只有一个拉伸明星出)呈现明星都必须有这一点,因为问题。下面是方法buildRatingBarDrawables
:
public static Drawable buildRatingBarDrawables(Bitmap[] images) {
final int[] requiredIds = { android.R.id.background,
android.R.id.secondaryProgress, android.R.id.progress };
final float[] roundedCorners = new float[] { 5, 5, 5, 5, 5, 5, 5, 5 };
Drawable[] pieces = new Drawable[3];
for (int i = 0; i < 3; i++) {
ShapeDrawable sd = new ShapeDrawable(new RoundRectShape(
roundedCorners, null, null));
BitmapShader bitmapShader = new BitmapShader(images[i],
Shader.TileMode.REPEAT, Shader.TileMode.CLAMP);
sd.getPaint().setShader(bitmapShader);
ClipDrawable cd = new ClipDrawable(sd, Gravity.LEFT,
ClipDrawable.HORIZONTAL);
if (i == 0) {
pieces[i] = sd;
} else {
pieces[i] = cd;
}
}
LayerDrawable ld = new LayerDrawable(pieces);
for (int i = 0; i < 3; i++) {
ld.setId(i, requiredIds[i]);
}
return ld;
}
所以,一切都很好在Android ICS和更新,但在姜饼我有一些奇怪的情况。首先有时在姜饼上一切都很好。但往往是没有明星。带点的矩形条总是正确的,但星星有时会消失。下面是示例屏幕从ListView
其使用的评价栏的每一个行:
就像你所看到的,有时候是好的,有时不:/我有我的导航slidingMenu这个等级吧当我缓慢地滑动时会显示星星,但在滑动结束后(当onOpened应该调用时),星星会消失。
有你,让我与快乐任何thougths :)
我添加xml文件的评级布局:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/avatar_layout"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="center" >
<RatingBar
android:id="@+id/ranking_bar"
android:layout_width="wrap_content"
android:layout_height="30dp"
android:layout_centerHorizontal="true"
android:clickable="false"
android:focusable="false"
android:isIndicator="true"
android:numStars="3"
android:progressDrawable="@drawable/krinsen_rating"
android:stepSize="0.1" />
<TextView
android:id="@+id/ranking_bar_position"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="@id/ranking_bar"
android:layout_centerHorizontal="true"
android:contentDescription="@string/register_avatar"
android:paddingBottom="2dp"
android:paddingLeft="8dp"
android:paddingRight="8dp"
android:paddingTop="2dp"
android:textColor="@android:color/white"
android:textSize="14sp"
android:textStyle="bold" />
</RelativeLayout>
当星星消失了,没有你看用层次结构查看器在组成视图中查看其状态(如果它们具有适当的大小)? – Luksprog
您是否尝试过不同屏幕尺寸的姜面包设备,可能是屏幕尺寸问题? – user1634451
