安卓开发笔记——关于java.lang.RuntimeException: Unable to start activity ComponentInfo{......}问题的解决方案

笔者在实现一个消息上下轮播时,遇到APP闪退:

将日志打印出来:

Process: com.ghl.intelligence, PID: 6557  
java.lang.RuntimeException: Unable to start activity ComponentInfo{com.ghl.intelligence/com.ghl.intelligence.MainActivity}: android.view.InflateException:
 Binary XML file line #154: Error inflating class LooperTextView
                                                     at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2435)    

具体内容为:

在LooperTextView前面加上com.ghl.intelligence.即可成功解决:

 <com.ghl.intelligence.LooperTextView
                android:layout_marginTop="3dp"
                android:layout_marginBottom="3dp"
                android:id="@+id/looperview"
                android:layout_width="match_parent"
                android:layout_height="60px"
                android:layout_marginLeft="3dp"
                android:background="#00ffff">
                </com.ghl.intelligence.LooperTextView>
