How to display the user entered text below the text field

Question

I'm a begineer in android. I learned from the developer.android.com, how to display a text by calling another activity. I want to display the user entered text in the same window. i.e., slow the text field(center). please anyone help me. I'm a beginner in android and I have just started to learn android.

mainactivity.java file

public void displayMessage(View view){
        EditText editText = (EditText) findViewById(R.id.edit_message);
        String message = editText.getText().toString();

        // Set the text view as the activity layout
        setContentView(message);
    }

Main Activity.java file. What functionalities should i add to the displayMessage method?

strings.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>

    <string name="app_name">SimpleApp</string>
    <string name="edit_message">Enter Something</string>
    <string name="button_send">Send</string>
    <string name="action_settings">Settings</string>
    <string name="title_activity_main">MainActivity</string>

</resources>

Answer 1

//first you need an xml file for the layout that will have 3 widgets      (TextView,EditText,Button)

//in the Activity you implement onclicklistener and in onCreate method
setContentView(R.layout.yourxmlfile);
EditText editText = (EditText) findViewById(R.id.edit_message);
 texxt = (TextView ) findViewById(R.id.text_view);
findViewById.(R.id.your_button).setOnclickListener(this)

@Override
public void onClick(View v){
String message = editText.getText().toString();
texxt.setText(message);
}
