如何在警报对话框上显示用户输入的详细信息？

Question

Please, i would like to show back details after the user must have input something, back on alert dialog box in Android studio. I used this code below:

editText = (EditText) findViewById(R.id.my_edit_txt);
editText.getText().toString(); 

But it doesn't show on the confirmation dialog box I created.

It looks like you didn't set the text of your AlertDialog, but this is just an assumption because there is not enough code in your question. Calling editText.getText().toString() does not do anything but return a String. It does not assign it to anything. An example with an AlertDialog would be the following:

AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
builder.setMessage(editText.getText().toString());
builder.setPositiveButton(R.string.ok, new DialogInterface.OnClickListener() {
           public void onClick(DialogInterface dialog, int id) {
               // User clicked OK button
           }
       });
builder.setNegativeButton(R.string.cancel, new DialogInterface.OnClickListener() {
           public void onClick(DialogInterface dialog, int id) {
               // User cancelled the dialog
           }
       });
// Set other dialog properties
...

// Create the AlertDialog
AlertDialog dialog = builder.create();

I've took this example from Android Developers and modified it so that it includes the text of your EditText. This code should work because you not only call the toString() method but also assign it's return value to the AlertDialog's message property.

This is my entire code for the alert dialog box:

public void alertdialog(View view){

           mybtn.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View view) {
                    AlertDialog.Builder cfmalt = new AlertDialog.Builder(Dashboard.this);
                    //cfmalt.setMessage("Do you want to quit?").setCancelable(false);
                   //editText.getText().toString();
                    cfmalt.setMessage(editText.getText().toString()+"\n"+ vol_edit2.getText().toString());
                    cfmalt.setMessage(dt.getMonth())
                    //cfmalt.setMessage("Name:").setMessage(vol_edit2.getText().toString());


                    cfmalt.setPositiveButton("Yes", new DialogInterface.OnClickListener() {
                        @Override
                        public void onClick(DialogInterface dialogInterface, int i) {
                            finish();
                        }
                    });
                    cfmalt.setNegativeButton("No", new DialogInterface.OnClickListener() {
                        @Override
                        public void onClick(DialogInterface dialogInterface, int i) {
                            dialogInterface.cancel();
                        }
                    });
