Sorry for the confusion I posted the Worng Logcat info. I updated the question. I want to click Start to start a thread then when enter is clicked i want the thad to continue and get the message and handle the message in the thread then output it to the main thread and update the text view. How would i start a thread to wait for enter to be pressed and get the bundle for the Handler? Here is my Code:

public class MainActivity extends Activity implements OnClickListener {
Handler mHandler;
Button enter;
Button start;
TextView display;
String dateString;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    enter = (Button) findViewById(R.id.enter);
    start = (Button) findViewById(R.id.start);
    display = (TextView) findViewById(R.id.Display);
    enter.setOnClickListener(this);
    start.setOnClickListener(this);

    mHandler = new Handler() {  <=============================This is Line 31
        public void handleMessage(Message msg) {
            // TODO Auto-generated method stub
            super.handleMessage(msg);
            Bundle bundle = msg.getData();
            String string = bundle.getString("outKey");
            display.setText(string);

        }
    };
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.main, menu);
    return true;
}

@Override
public void onClick(View v) {
    // TODO Auto-generated method stub
    switch (v.getId()) {
    case R.id.enter:
        Message msgin = Message.obtain();
        Bundle bundlein = new Bundle();
        String in = "It Works!";
        bundlein.putString("inKey", in);
        msgin.setData(bundlein);
        notifyAll();

        break;
    case R.id.start:
        new myThread().hello.start();
        break;
    }
}

public class myThread extends Thread {
    Thread hello = new Thread() {
        @Override
        public void run() {
            // TODO Auto-generated method stub
            super.run();
            Looper.prepare();
            try {
                wait();
            } catch (InterruptedException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
            Handler Mhandler = new Handler() {

                @Override
                public void handleMessage(Message msg) {
                    // TODO Auto-generated method stub
                    super.handleMessage(msg);
                    Bundle bundle = msg.getData();
                    dateString = bundle.getString("inKey");
                }

            };
            Looper.loop();

            Message msg = Message.obtain();
            Bundle bundle = new Bundle();

            bundle.putString("outKey", dateString);
            msg.setData(bundle);
            mHandler.sendMessage(msg);

        }

    };

}
}
