[android-developers] Trying to send a message to second activity and then change the second activity textView text to that message

[zep]

Hi.

For the main acitivity I have this code:

package com.example.myapp_0;

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.Menu;
import android.view.View;
import android.widget.EditText;

public class MainActivity extends Activity {

 public final static String EXTRA_MESSAGE = "com.example.myapp.MESSAGE";
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        getMenuInflater().inflate(R.menu.activity_main, menu);
        return true;
    }
    
    public void send(View view){
    Intent intent = new Intent(this, MessageActivity.class);
    EditText editText = (EditText) findViewById(R.id.edit_message);
    String message = editText.getText().toString();
    intent.putExtra(EXTRA_MESSAGE, message);
    startActivity(intent);
    
    }
    
}

For the second activity I have this code:

package com.example.myapp_0;

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.widget.TextView;

public class MessageActivity extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    // Get the message from the intent
    Intent intent = getIntent();
    String message = intent.getStringExtra(MainActivity.EXTRA_MESSAGE);

    
    
   
   TextView textView = (TextView) findViewById(R.id.textView2);
   
    textView.setText(message);

    // Set the text view as the activity layout
    setContentView(R.layout.activity_message);
}


The id textView2 is correct. Also the layout names.

But when I try to emulate it.. it crashes.

What I´m doing wrong?

Thanks.
