How do i get a EditText to display in my TextView?

Question

Basically I'm trying to get my EditText with a button "Ok" to display what was written to show up in a TextView output. Once the "Ok" button is pressed it get the text what was entered in the EditText and display in the TextView.

Been searching around and can't find anything that works. Can anyone help?

Edit: 1) really appreciate the responds and help guys. 2) I think I"m asking this wrong. What I'm trying to do is creating an option where the user can add their own Text into an activity.

Edit: THANK YOU FOR THE HELP!!!!!!!!!!!!

Answer 1

Let's suppose the EditText is named as et, TextView is named as tv and your Button is named a as bt.. Now declare your EditText, TextView and Button, below your class name like this:

public class EditToText extends Activity{
EditText et;
TextView tv;
Button bt;
------
------
 }

Now in your onCreate method and after setContentView do as mentioned below :

------
------
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    et = (EditText) findViewById(R.id.edittext); //EditText is defined as edittext in xml
    tv = (TextView) findViewById(R.id.textview); //TextView is defined as textview in xml
    bt = (Button) findViewById(R.id.button); //Button is defined as button in xml

    //When button is clicked
    bt.setOnClickListener(new View.OnClickListener(){   
    @Override 
        public void onClick(View v) {
            String txt = et.getText().toString(); //Get txt from et when button is clicked
            tv.setText(txt); //Set text extracted from et in tv

        } 
    }); 
}
------
------

Hope this Helps!

Get Value from EditText

editText.getText().toString();

Set value to TextView in Button Click

textView.setText(editText.getText().toString());

Update:

implement Button Onclick(...) like

 Button negativeButton = (Button) findViewById(R.id.ButtonID);

 negativeButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
             textView.setText(editText.getText().toString());
        }
    });

Answer 3

Use in your Activity in OnCreate()

    Button _ok =      (Button) findViewById(R.id.idofButton);
   TextView result = (TextView ) findViewById(R.id.idofTextView);
    EditText entrytext = (EditText ) findViewById(R.id.idofEditText);

   _ok.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
         result .setText(entrytext .getText().toString());
    }
});
