我正在尝试使用HoloCircularProgressBar by Pascal Welsch并且它在Android Studio中给我提出问题（v0.5.3，因为它的价值，当我使用Eclipse时它并没有给我任何问题，而且我没有' t在迁移期间改变任何东西）并且当它试图从布局XML中膨胀时我一直收到这个错误：

我的XML布局：
...
<de.passsy.holocircularprogressbar.HoloCircularProgressBar
android:id="@+id/recordingProgress"
android:layout_width="110dp"
android:layout_height="110dp"
android:layout_centerInParent="true"
app:marker_visible="false"
app:progress_background_color="@color/lt_grey"
app:progress_color="@color/landingPageStartColor"
app:thumb_visible="false" />
...
这是HoloCircularProgressBar的相关代码
/**

*

* the attrs
*/
public HoloCircularProgressBar(final Context context, final AttributeSet attrs) {
// line 218 vv
this(context, attrs, R.attr.circularProgressBarStyle);
}
/**

*
* @param context

*/
public HoloCircularProgressBar(final Context context, final AttributeSet attrs, final int defStyle) {
super(context, attrs, defStyle);
// load the styled attributes and set their properties
final TypedArray attributes = context.obtainStyledAttributes(attrs, R.styleable.HoloCircularProgressBar,
defStyle, 0);
setProgressColor(attributes.getColor(R.styleable.HoloCircularProgressBar_progress_color, Color.CYAN));
setProgressBackgroundColor(attributes.getColor(R.styleable.HoloCircularProgressBar_progress_background_color,
Color.MAGENTA));
setProgress(attributes.getFloat(R.styleable.HoloCircularProgressBar_progress, 0.0f));
setMarkerProgress(attributes.getFloat(R.styleable.HoloCircularProgressBar_marker_progress, 0.0f));
setWheelSize((int) attributes.getDimension(R.styleable.HoloCircularProgressBar_stroke_width, 10));
mIsThumbEnabled = attributes.getBoolean(R.styleable.HoloCircularProgressBar_thumb_visible, true);
mIsMarkerEnabled = attributes.getBoolean(R.styleable.HoloCircularProgressBar_marker_visible, true);
mGravity = attributes.getInt(R.styleable.HoloCircularProgressBar_android_gravity, Gravity.CENTER);
attributes.recycle();
mThumbRadius = mCircleStrokeWidth * 2;
updateBackgroundColor();
updateMarkerColor();
updateProgressColor();
// the view has now all properties and can be drawn
mIsInitializing = false;
