How to handle autolink click event of android textview?

Question

Here is my xml code for autolink in textview.

 <TextView
                style="@style/statusTextList"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:autoLink="web"
                android:textColorLink="@color/hyperlinkColor"
                android:linksClickable="true"
                android:textColor="#ffffff"
                android:autoSizeTextType="uniform"
                />

Code works perfectly fine. Web url in TextView are auto highlighted and able to click. But on clicking in hyperlink it ends with an error.

Calling startActivity() from outside of an Activity context requires the FLAG_ACTIVITY_NEW_TASK flag. Is this really what you want?

Note: TextView is placed inside recyclerview item

Question : How to resolve this issue? or how to handle hyperlink click event programmatically?

Answer 1

I can not reproduce your error actually.

You can use code below to handle hyperlink click event programmatically:

override fun onBindViewHolder(viewHolder: ViewHolder, position: Int) {
    viewHolder.textView.apply {
        // replace first dataSet[position] with your url
        // replace second dataSet[position] with your url description
        text = Html.fromHtml(
            "<a href=\"${dataSet[position]}\">${dataSet[position]}</a> ")
        movementMethod = LinkMovementMethod.getInstance()
        setLinkTextColor(Color.BLUE)
    }
}

Full working code with xml:

// MainActivity.kt
class MainActivity : AppCompatActivity() {
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)
        val recyclerView = findViewById<RecyclerView>(R.id.rv)
        recyclerView.adapter = CustomAdapter(arrayOf("https://www.google.com"))
    }
}

class CustomAdapter(private val dataSet: Array<String>) :
    RecyclerView.Adapter<CustomAdapter.ViewHolder>() {

    class ViewHolder(view: View) : RecyclerView.ViewHolder(view) {
        val textView: TextView

        init {
            textView = view.findViewById(R.id.tv_test)
        }
    }

    override fun onCreateViewHolder(viewGroup: ViewGroup, viewType: Int): ViewHolder {
        val view = LayoutInflater.from(viewGroup.context)
            .inflate(R.layout.item_test, viewGroup, false)
        return ViewHolder(view)
    }

    override fun onBindViewHolder(viewHolder: ViewHolder, position: Int) {
        viewHolder.textView.text = dataSet[position]
    }

    override fun getItemCount() = dataSet.size

}
