How do I display text in another activity [ANDROID]?

Question

I am trying to take text that was generated in one activity, that was concatenated, "MainActivity.java," and display it on screen using another activity, "DICS.java." I am having trouble figuring out how to do that.

MainActivity.java

package com.example.tristan.a1p1n1;

import android.content.Intent;
import android.net.Uri;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.EditText;


public class MainActivity extends AppCompatActivity {


    public final static String EXTRA_MESSAGE = "com.example.tristan.a1p1n1.MESSAGE";
    /**
     * ATTENTION: This was auto-generated to implement the App Indexing API.
     * See https://g.co/AppIndexing/AndroidStudio for more information.
     */
    private GoogleApiClient client;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        // ATTENTION: This was auto-generated to implement the App Indexing API.
        // See https://g.co/AppIndexing/AndroidStudio for more information.
        client = new GoogleApiClient.Builder(this).addApi(AppIndex.API).build();
    }

    public void sendMessage(View view)
    {
        Intent intent = new Intent(this, DICS.class);
        EditText editText = (EditText) findViewById(R.id.editText);
        EditText editText2 = (EditText) findViewById(R.id.editText2);
        String message = editText.getText().toString() + editText2.getText().toString();
        intent.putExtra(EXTRA_MESSAGE, message);
        startActivity(intent);

    }}

    @Override

        super.onCreate(savedInstanceState);
        setContentView(R.layout.dics);

    }
}

Thank you. now how to I add that into the XML file show it will show up on screen? – Tristan Feb 11 '17 at 22:56
TextView mTextView = (TextView) findViewById(R.id.textview2); mTextView.setText(dataGet); – MateenSheikh Feb 11 '17 at 22:59
Is this the correct way of putting it into the XML file: android:text="@+id/mTextView" – Tristan Feb 11 '17 at 23:08
If you want to put some static text from xml just write android:text="your text" – MateenSheikh Feb 11 '17 at 23:22

Get the intent and then proceed to get the string from the intent

Intent intent = getIntent();
String stringFromIntent = intent.getStringExtra(MainActivity.EXTRA_MESSAGE);
