Wie zeige ich Text in einer anderen Aktivität an [ANDROID]?

Question

Ich versuche, Text, der in einer Aktivität, die verkettet wurde, "MainActivity.java" generiert wurde, und zeigen Sie es auf dem Bildschirm mit einer anderen Aktivität, "DICS.java." Ich habe Probleme herauszufinden, wie das geht.

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); 

    }}

Answer 1

Intent Absicht = getIntent() zu erhalten; Zeichenfolge dataGet = intent.getExtras(). GetString ("EXTRA_MESSAGE");

Answer 2

die Absicht holen und dann gehen die Zeichenfolge der Absicht

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