How to open File CHooser window on button press in Android app using Kotlin?
In your activity add the button click to add an intent:
btnBack.setOnClickListener {
val intent = Intent()
.setType("*/*")
.setAction(Intent.ACTION_GET_CONTENT)
startActivityForResult(Intent.createChooser(intent, "Select a file"), 111)
}
Set a custom requestCode, I set 111
Add the onActivityResult
in your activity to catch the result:
override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
super.onActivityResult(requestCode, resultCode, data)
if (requestCode == 111 && resultCode == RESULT_OK) {
val selectedFile = data?.data //The uri with the location of the file
}
}
Now selectedFile
will contain the location to what they selected.
