App crashed when button clicked

Question

I'm using onclicklistener and app crashes when I'm using the button... the crash happens at the first page when I use it's only button. Cant find the issue... heres the mainActivity:

    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        Button btn = (Button)findViewById(R.id.button1);
        final EditText ed = (EditText)findViewById(R.id.editText1);
        final String str = ed.getText().toString();
        btn.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {
                Intent intent = new Intent(MainActivity.this, NotesPage.class);
                intent.putExtra("username", str);
                startActivity(intent);
            }
        });

    }
}

And the notespage:

public class NotesPage extends ListActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.notespage);
        Button btn = (Button)findViewById(R.id.button1);
        TextView tx = (TextView)findViewById(R.id.textView2);
        Intent intent = getIntent();
        final String str = intent.getStringExtra("username");
        tx.setText("Hello"+str);
        btn.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {
                Intent intent = new Intent(NotesPage.this, Addnote.class);
                startActivity(intent);
            }
        });
    }

}

Manifest:

<application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >
    <activity
        android:name="com.example.noteslist.MainActivity"
        android:label="@string/app_name" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
    <activity android:name="NotesPage"></activity>
    <activity android:name="Addnote">
    </activity>
</application>

Post the logcat. Also, "I've added the activity at the manifest..." make sure **all** `Activities` are added to the `manifest` — codeMagic, Nov 18 '13 at 19:51
**Caused by: java.lang.RuntimeException: Your content must have a ListView whose id attribute is 'android.R.id.list'** the `manifest` said you what is the problem — Rick, Nov 18 '13 at 19:57
could you add the mainActivity.xml the problem is in the declaration of the listview in the xml view file — Benjamin RD, Nov 18 '13 at 19:58

Your NotesPage is extends ListActivity not an Activity and y0u dont have any listview in your NotesPage

So Change the extends from ListActivity to Activity

According to this line

Caused by: java.lang.RuntimeException: Your content must have a ListView whose id attribute is 'android.R.id.list'

you don't have a ListView with the appropriate id in notespage.xml. You should have something like

ListView
    android:id="@android:id/list"

When you extends ListActivity you must have a ListView with this id. If you only extends Activity then you don't need this.

Off-Topic

You can see this answer about reading logcat this will give you a good place to start so you can debug more yourself and know what parts are most relevant when you still can't get it.

Also, you can filter your logcat by "error" to see the exception easier.
