Yesterday was too late, today teaches you to use debug mode to analyze program execution order

Or with yesterday's XML file parsing to do chestnut, hope that through this delicious chestnut can extrapolate learn to use debug to see the source code and find bugs

There are five main types of events
Event type of Start_document:xml Header = 0
End_document:xml Tail Event Type =1
Start_tag: Event type of the start node = 2
End_tag: Event type of end node = 3
Text: The event type of the literal node = 4

Our XML file:

<?xml version= "1.0" encoding= "Utf-8"?><weather>    <city>        <name> Anyang </name>        <temp>-8℃</temp>        <pm25>120</pm25>    </city>    <city>        < Name> Beijing </name>        <temp>-12℃</temp>        <pm25>500</pm25>    </city>    <city>        <name> Shanghai </name>        <temp>2℃</temp>        <pm25>60</ Pm25>    </city></weather>

The code doesn't stick to the code that was parsed by the XML file yesterday.

1 first hit a breakpoint (double click)

2 Package---------Right-click-------------Debug as--------------Android application (no way to write a path)

3............#################

4 point Simulator on the button of our program and then see the menu bar below a line of small icons

5 We chose step Over (F6) not to enter the sub-method:
