@DesignerComponent(version = 1,
description =“A SpanText Extension”,
category = ComponentCategory.EXTENSION,
nonVisible = true,
iconName = “images/extension.png”)
@SimpleObject(external = true)

public class SpanText extends AndroidNonvisibleComponent {

public static final int VERSION = 1;
private ComponentContainer container;

private String myText;
private String keyWord;
private TextView tv;


public SpanText(ComponentContainer container) {
    super(container.$form());
    this.container = container;
}

	
@SimpleFunction(description = "  Set Text  WordToSpan")
public void highlight(String myText,String keyWord  ){ 

	WordToSpan highlight = new WordToSpan();	
    highlight.setBackgroundHIGHLIGHT(Color.YELLOW)
	.setColorHIGHLIGHT(Color.RED)
    .setHighlight(myText, keyWord)
    .setUnderlineTAG(true)
    .into(tv);
    }

}

the first thing put your java files in the same folder with the same package name and check

mrris · October 22, 2018, 2:58pm

i have make like this:
com/myex/SpanText/SpanText.java

i thing correct

mrris · October 22, 2018, 2:59pm

or maybe false

or like that:
com/myex/SpanText.java

?

Said_Dev · October 22, 2018, 3:09pm

Put both files in the same directory:
com/myex/SpanText/SpanText.java
com/myex/SpanText/WordToSpan.java

and inside the both file put the same package name: package co.com.myex.SpanText;

mrris · October 22, 2018, 3:31pm

Ok tomorow i try again
thanks sir @Said_Dev

mrris · October 22, 2018, 3:34pm

its correct sir?

package co.com.myex.SpanText;

mrris · October 23, 2018, 12:52am

Stiil error sir

i think this false ?

private String myText;
private String keyWord;
private TextView tv;

how to be work like this:

String myText = “Any code and resources in the Android library anywhere love code.”;
String keyWord = “any code”;
TextView tv = (TextView)findViewById(R.id.tx);

Said_Dev · October 23, 2018, 8:08am

TextView tv = new TextView(context);

mrris · October 23, 2018, 2:56pm

sir ,i get error with variable context
i hve add

import android.content.Context;

still error ?
why

Red_Panda · October 23, 2018, 3:57pm

Your constructor should be

public SpanText(ComponentContainer container) {
    super(container.$form());
    this.container = container;
    context = (Context) container.$context();
}

Then you can use context

mrris · October 23, 2018, 4:28pm

Thank you sir @Red_Panda
i will try again …
