将SIMPLE TEXT TAG和CUSTOM VIEW TAG多次切换后程序奔溃，日志显示空指针异常
FATAL EXCEPTION: main Process: com.moxun.tagcloud, PID: 20838 java.lang.NullPointerException: Attempt to invoke virtual method 'void android.view.View.setBackgroundColor(int)' on a null object reference at com.moxun.tagcloud.ViewTagsAdapter.onThemeColorChanged(ViewTagsAdapter.java:38) at com.moxun.tagcloudlib.view.TagCloudView.onLayout(TagCloudView.java:282) at android.view.View.layout(View.java:15697) at android.view.ViewGroup.layout(ViewGroup.java:5050) at android.widget.LinearLayout.setChildFrame(LinearLayout.java:1703) at android.widget.LinearLayout.layoutVertical(LinearLayout.java:1557) at android.widget.LinearLayout.onLayout(LinearLayout.java:1466) at android.view.View.layout(View.java:15697) at android.view.ViewGroup.layout(ViewGroup.java:5050)
原因是ViewTagsAdapter中onThemeColorChanged方法未做判空过滤。
