Error Correction for the mxml component development example of the custom player in Flash Builder 4 Quick Start

We previously recommended Adobe's official video tutorial to learn flex. After all, it is in English and inconvenient. Later, I found that the flash Builder 4 Quick Start on the igrui forum is a Chinese language. It speaks very well and can be viewed together with Adobe's official video tutorials for a better understanding.

However, on the P73 page of this tutorial, there is a problem with the example of developing a custom player component using mxml, and errors such as "videoelement cannot be parsed as a component" may occur. After verification, the special correction is as follows:

1. In the example, there are about 5th rows of customplayer. mxml under the customplayer project and about 4th rows of customplayer. mxml under the customplayersample project:

Xmlns: MX = "Library: // ns.adobe.com/flex/halo" should be changed:

Xmlns: MX = "Library: // ns.adobe.com/flex/mx"

2. About 50th lines of customplayer. mxml under the customplayersample project:

Selectionchanged = "Play (event);" in <s: List> should be changed:

Change = "Play (event );"

3. About 6th lines of customplayer. mxml under the customplayer project:

Here, you need to download two files: audio. As and audioevent. As, and then paste them into the project,

Then xmlns: rojored = "com. rojored. View. Controls. *" should be changed:

Xmlns: rojored = "../COM. rojored. Controls .*"

4. About 163rd lines of customplayer. mxml under the customplayer project:

<Rojored: audio id = "audio"/>:

<Local: audio id = "audio"/>

In addition, add the following statement after the creationcomplete = "Init ();" in line 8th:

Xmlns: Local = "*">

5. About 170th lines of customplayer. mxml under the customplayer project:

<S: videoelement id = "video" should be changed:

<S: videoplayer id = "video"

In addition, around 141 rows:

Playobject is videoelement should be modified:

Playobject is videoplayer

6. About 217th lines of customplayer. mxml under the customplayer project:

Valueinterval = "0" should be changed:

Snapinterval = "0"
