B4J Question javaobject not matched

xulihang · Aug 23, 2018

Hi guys,

I am new to javaobject. I have trouble accessing the pinyin4j library using javaobject. The code I write is like this:

B4X:

#AdditionalJar: pinyin4j-2.5.0
......
Dim jo As JavaObject
jo.InitializeStatic("net.sourceforge.pinyin4j.PinyinHelper").RunMethod("toHanyuPinyinStringArray",Array As Object("你"))

and I get this wrong message:

B4X:

java.lang.RuntimeException: Method: toHanyuPinyinString not matched.

What should I do to solve this problem?

Thanks.

I figured this out. The parameter's type should be char.

B4X:

Dim singlechar As Char
singlechar="你"
Dim jo As JavaObject
Dim strArray() As String
strArray=jo.InitializeStatic("net.sourceforge.pinyin4j.PinyinHelper").RunMethod("toHanyuPinyinStringArray",Array As Object(singlechar))
For Each pinyin As String In strArray
    Log(pinyin)
Next

Don't know if this might be useful for you but you can use a pinyin4j wrapper I wrote for B4A. It will work with B4J too.
You can download the libraries here:
https://www.b4x.com/android/forum/threads/b4a-pinyin-b4a拼音.71799/#content
Put the libraries in your additional library folder.

I am attaching a sample project in B4J.
