Show custom alert dialog with EditText inside it - Android Java

Overview

This is for my own reference actually but if someone is looking for a solution on how to create a custom alert dialog, then this is the right tutorial for you.

Create a new layout file under res/layout

custom_dialog.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:padding="10dp"
    android:orientation="vertical">

    <EditText
        android:id="@+id/edit1"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:inputType="text" />

</LinearLayout>

I have shown the custom alert dialog when user presses a menu item but you can also do it using button click. Just use this code in public void buttonAction(final View v) method. Now in the activity where you want to show the custom alert dialog, add

MainActivity.java

In onOptionsItemSelected(MenuItem item) add the following,

@Override
public boolean onOptionsItemSelected(MenuItem item) {
int id = item.getItemId();

    switch (id) {
    	case R.id.action_custom_dialog:
            showChangeLangDialog();
            return true;

        //similarly write for other actions

        default:
            return super.onOptionsItemSelected(item);
    }
    return true;
}

Now add the following method after onOptionsItemSelected(). This is the important part,

public void showChangeLangDialog() {
    AlertDialog.Builder dialogBuilder = new AlertDialog.Builder(this);
    LayoutInflater inflater = this.getLayoutInflater();
    final View dialogView = inflater.inflate(R.layout.custom_dialog, null);
    dialogBuilder.setView(dialogView);

    final EditText edt = (EditText) dialogView.findViewById(R.id.edit1);

    dialogBuilder.setTitle("Custom dialog");
    dialogBuilder.setMessage("Enter text below");
    dialogBuilder.setPositiveButton("Done", new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface dialog, int whichButton) {
            //do something with edt.getText().toString();
        }
    });
    dialogBuilder.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface dialog, int whichButton) {
            //pass
        }
    });
    AlertDialog b = dialogBuilder.create();
    b.show();
}

That’s it. If you want to see how to use a spinner inside the custom alert dialog, see this tutorial.
