I'm starting on android and I'm doing a program in which I have several EditText and when I click on a button I send a Toast with all the information of each of the Edit text, how can I send it the toast but with the information of each of the EditText but in a Toast

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        Button butoon = (Button)findViewById(R.id.button);
        butoon.setOnClickListener(this);
    }

    public void onClick(View v)
    {
        EditText text = (EditText)findViewById(R.id.editText_Nombre);
        Toast toast = Toast.makeText(getApplicationContext(),"La reservacion ",Toast.LENGTH_SHORT
        );

        Toast(text);
        toast.show();
    }

    private Toast Toast(EditText text)
    {
        return null;
    }
}

The second parameter that receives Toast.makeText() is a CharSequence . You can get the text of a EditText using EditText.getText() , and then convert it to String through the toString() method. In your code this would be:

public void onClick(View v)
{
    EditText text = (EditText)findViewById(R.id.editText_Nombre);
    Toast toast = Toast.makeText(getApplicationContext(), "La reservación " + text.getText().toString(), Toast.LENGTH_SHORT);

    toast.show();
}

Let me know if it works!

First to use this method in this way, receiving a view as a parameter

public void onClick(View v){

You must call it from the property android:onClick from your Layout or your class implements the class onClicklistener , apparently it is like that since you are defining the listener in this way:

butoon.setOnClickListener(this);

To add the value of EditText just get it this way, getting the CharSequene and convert it to String using the method toString()

String valorEditText = text.getText().toString();

Your code would be this way

    public void onClick(View v)
    {
        EditText text = (EditText)findViewById(R.id.editText_Nombre);
        String valorEditText = text.getText().toString();  
       Toast.makeText(getApplicationContext(),"La reservacion " + valorEditText,Toast.LENGTH_SHORT).show();

       /*No es necesaria esta forma 
Toast toast = Toast.makeText(getApplicationContext(),"La reservacion ",Toast.LENGTH_SHORT
        );

        Toast(text);
        toast.show();*/
    }
    /*metodo no necesario
    private Toast Toast(EditText text)
    {
        return null;
    }*/

If you have several EditText get the text you have inside by

 String valorEditText1 = text1.getText().toString();
 String valorEditText2 = text2.getText().toString();
 String valorEditText3 = text3.getText().toString();
 ...
 ...

and concatenate them to the toast message.

You must declare the text outside the click code and onCreate, so that you can reuse it anywhere you want, what you want to do is done with getText().toString() , leave a comment there and leave a link below if you want customize it even more.

EditText text;

    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        text = (EditText)findViewById(R.id.editText_Nombre);
        Button butoon = (Button)findViewById(R.id.button);
        butoon.setOnClickListener(this);
    }

    public void onClick(View v)
    {
     String dato = text.getText().toString();
     /* El metodo getText() obtiene el dato escrito con el metodo toString()
     se convierte a String para poder manipularlo como tal, por ultimo
     se muestra en el textView con el metodo .setText()
     */
     Toast toast = Toast.makeText(getApplicationContext(), dato,Toast.LENGTH_SHORT);

        toast.show();
    }
