Android Question How to findNext with runmethod2 in webview?

[watesoft]

Sub Activity_Click
   FindAll(WebView1, "Basic4android")
End Sub

Sub FindAll (w As WebView, s As String) As Int
   Dim r As Reflector
   r.Target = w
   Return r.RunMethod2("findAll", s, "java.lang.String")
End Sub

I load a long html text in webview ,find and highlight all the keyword with above code, I want to see them one by one,but when I use below code,error occurred:"NoSuchMethodException: findNext [class java.lang.String]", Where is my fault?

Sub FindNext_Click
    FindNext(WebView1, "Basic4android")
End Sub

Sub FindNext (w As WebView, s As String) As Int
   Dim r As Reflector
   r.Target = w
   Return r.RunMethod2("findNext", s, "java.lang.String")
End Sub

Try this:
1. Find all:

Dim jo As JavaObject = WebView1
jo.RunMethod("findAllAsync", Array(s))

2. Next match:

Dim jo As JavaObject = WebView1
jo.RunMethod("findNext", Array(True))

Requires Android 4.1+ (api 16)

Hi Erel, I met another problem,I want to match and highlight multi keywords in webview,like below:

Dim SS() as string
SS = Array As String("AAA", "BBB", "CCC")
Dim i as Int
Dim jo As JavaObject = WebView1
for i=0 to SS.length-1
     jo.RunMethod("findAllAsync", Array(SS(i)))
next

Result: only "CCC" is highlighted, why, I want to highlight "AAA" and "BBB" and "CCC".

 

[Erel]

Try it like this:

Dim SS() as string = Array As String("AAA", "BBB", "CCC")
Dim jo As JavaObject = WebView1
for Each s As String In SS
     jo.RunMethod("findAllAsync", Array(s))
     Sleep(200)
next

Try it like this:

Dim SS() as string = Array As String("AAA", "BBB", "CCC")
Dim jo As JavaObject = WebView1
for Each s As String In SS
     jo.RunMethod("findAllAsync", Array(s))
     Sleep(200)
next

Thanks Erel,let me try the code.

Hello, I have try the code of Erel (#5, Feb 9, 2018) for match and highlight multi keywords in webview.
It don't works. Only "CCC" is highlighted.
Did you find a solution ?
Thanks

Sorry,I tried my best for a long time ,but failed.

I guess only ONE highlighting can be active at a time.

https://developer.android.com/reference/android/webkit/WebView

Finds all instances of find on the page and highlights them, asynchronously. Notifies any registered FindListener. Successive calls to this will cancel any pending searches.

So, calling this method will remove the last highlight...

When online PDF file is opened in webview, search matched text is not highlighted. Is there way to fix that?
