Android code no error, but run error

Rookie after 2 hours of adjustment, it is important to find the problem:

The code does not raise errors, the program always displays errors when running, the error is:

11-24 15:22:16.587:e/androidruntime (19903): FATAL exception:main
11-24 15:22:16.587:e/androidruntime (19903): java.lang.RuntimeException:Unable to start activity componentinfo{ Com.example.shikechannel/com.example.shikechannel.channelactivity}: Android.view.InflateException:Binary XML file Line #40: Error inflating class Com.handmark.pulltorefresh.library.PullToRefreshListView

If you look at the error, you know that there should be a layout problem, and I have a layout that says:

<include
Android:id= "@+id/chaneltheme"
layout= "@layout/channel_theme"/>

Without putting this include in a layout, the result is a bit of a conflict with the following,

The right way is:

<relativelayout
Android:layout_width= "Fill_parent"
android:layout_height= "50DP"
Android:background= "#ffffff"
>
<include
Android:id= "@+id/chaneltheme"
layout= "@layout/channel_theme"/>
</RelativeLayout>

In this way, the effect is good, will not report errors,

It took the rookie two hours to get to the truth:

1, must learn to see Logcat direction error, do not waste too much time in the right place.

2, Android layout also need to learn well.
