问题
My project now is how to make a Snackbar displayed at the bottom of the screen. The Snackbar contain with editText and three button for selection categories. I use LayoutInflater and follow these code for my script, and it's work. My problem now is, how to get response when user click the button ? Here my code
@Override
public void onClick(View v) {
CoordinatorLayout linearLayout = (CoordinatorLayout)findViewById(R.id.coordinatorLayout);
final Snackbar snackbar = Snackbar.make(linearLayout, "", Snackbar.LENGTH_INDEFINITE);
Snackbar.SnackbarLayout layout = (Snackbar.SnackbarLayout) snackbar.getView();
// Inflate your custom view with an Edit Text
LayoutInflater objLayoutInflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View snackView = objLayoutInflater.inflate(R.layout.custom_snac_layout, null);
// custom_snac_layout is your custom xml
layout.addView(snackView, 0);
snackbar.show();
}
and here my snacbar.xml layout
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

here is the source required to implement button listener to your snackbar custom layout.
@Override
public void onClick(View v) {
CoordinatorLayout linearLayout = (CoordinatorLayout)findViewById(R.id.coordinatorLayout);
final Snackbar snackbar = Snackbar.make(linearLayout, "", Snackbar.LENGTH_INDEFINITE);
Snackbar.SnackbarLayout layout = (Snackbar.SnackbarLayout) snackbar.getView();
// Inflate your custom view with an Edit Text
LayoutInflater objLayoutInflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View snackView = objLayoutInflater.inflate(R.layout.custom_snac_layout, null);
// custom_snac_layout is your custom xml
// button id for snackbar
Button button_mapel = (Button) snackView.findViewById(R.id.btn_mapel);
// perform button click listener
button_mapel.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// here perform your button click task
}
});
layout.addView(snackView, 0);
snackbar.show();
}

Follow this documentation
https://developer.android.com/training/snackbar/action.html
public class MyUndoListener implements View.OnClickListener{
&Override
public void onClick(View v) {
// Code to undo the user's last action
}
}
Now for setAction()
Snackbar mySnackbar = Snackbar.make(findViewById(R.id.myCoordinatorLayout),
R.string.email_archived, Snackbar.LENGTH_SHORT);
mySnackbar.setAction(R.string.undo_string, new MyUndoListener());
mySnackbar.show();

Try This,
Button btn_feed_back = (Button)snackView.findViewById(R.id.feedback);
btn_feed_back.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
}
});

You have to get id of your Button
. And have to set clickListener
.
You have to just replace your code with this.
I have put listener on btn_mapel
, you can put any other button according to your requirement.
Try this.
@Override
public void onClick(View v) {
CoordinatorLayout linearLayout = (CoordinatorLayout)findViewById(R.id.coordinatorLayout);
final Snackbar snackbar = Snackbar.make(linearLayout, "", Snackbar.LENGTH_INDEFINITE);
Snackbar.SnackbarLayout layout = (Snackbar.SnackbarLayout) snackbar.getView();
// Inflate your custom view with an Edit Text
LayoutInflater objLayoutInflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View snackView = objLayoutInflater.inflate(R.layout.custom_snac_layout, null);
// custom_snac_layout is your custom xml
Button mapelBt = (Button)snackView.findViewById(R.id.btn_mapel);
mapelBt.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// Get your button click callback here
}
});
layout.addView(snackView, 0);
snackbar.show();
}
