hi , i need one help can anyone tell how to restrict specific characters in searchView

Add textwatch listener and in afterTextChange method iterate over the Editable to find if the input contains your specific character and if found use replace method like(input.replace("specific_character","") and set that filtered input as text again

[Samir Basnet]

editText.addTextChangedListener { e  ->
    If(e?.any{it.contains("specific_character"){
     val filteredInput = it.toString().replace("specific_character","")
    editText?.setText(filteredInput)
    editText?.setSelection(filteredInput.length)
}
}

i don't want edit text

[Samir Basnet]

But logic is same just use this with searchview

[Samir Basnet]

Though i guess for searchview you have to reference its internal edittext

[san]

in search view you can't set filters

[san]

you can only replace the string on query text change method by matching the patterns

[Samir Basnet]

You can access searchviews internal textview that shows query using searchView?.findViewById(androidx.appcompat.R.id.search_src_text)

[san]

ok but there is any listeners for textView?

[Samir Basnet]

val tvQuery = searchView?.findViewById(androidx.appcompat.R.id.search_src_text)

searchView.setOnQueryTextListener(object : SearchView.OnQueryTextListener() {
fun onQueryTextSubmit(query: String?): Boolean {
return false
}

fun onQueryTextChange(newText: String?): Boolean {
if(newText?.any{it.contains("specific_character")}){
val filteredQuery = newText?.replace("specific_character","")
tvQuery.text = filteredQuery
}

return false
}
})

[Samir Basnet]

And use androidx.appcompat version of SearchView in import

[san]

🙂 👍🏻

[Samir Basnet]

Do let me know if works or not

[san]

sure
