Today, the editor will share with you the relevant knowledge points about how to solve the common problems in the production of Android templates, the content is detailed, and the logic is clear. I believe most people still know too much about this knowledge, so share this article for your reference. I hope you can get something after reading this article.

Why is the field added in the background and not displayed in the foreground?

The background only saves the data, and whether the foreground is displayed depends on the template. If the template does not call this field, it will not be displayed in the foreground.

[# if node.number = = 'abc'] reported an error, indicating that node.number is not defined. "class=" reference-link "> [# if node.number = =' abc'] reported an error, indicating that node.number is not defined.

What is not defined here means that the value is null, not that the field does not exist. Null pointer exception similar to java. Because not all columns have number (code) set in the background, if you encounter a column with an empty number, you will report an error.

You can do null value handling on node.number, such as [# if node.number! = = 'abc'].
