Проблемка в Android SDK Studio после переделывания в apk

В общем, я написал программу и при проверке эмулятором - она работает. В ней есть два Activity, с кнопками.Но когда я превратил программу в apk и запустил на телефоне, то она запускается, но в первом Activity, кнопки работают, а во втором Activity ничего не реагирует на касания(ни кнопки, ни ScrollView. В чём дело?

    protected void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.activity_phone_book);
      scrLay = (LinearLayout) findViewById(R.id.scrollLayout);
      btn1 = (Button) findViewById(R.id.button1);
      btn3 = (Button) findViewById(R.id.button4);
      btn4 = (Button) findViewById(R.id.button2);
      btn5 = (Button) findViewById(R.id.button0);
      id = 1;
      dial = new Dialog(this);
      btn4.setAlpha(0);
      btn4.setClickable(false);
      dial.setContentView(R.layout.dialog);
      btn2 = (Button) dial.findViewById(R.id.button5);
      et1 = (EditText) dial.findViewById(R.id.editText);
      et2 = (EditText) dial.findViewById(R.id.editText2);
      btn2.setOnClickListener(this);
      btn1.setOnClickListener(this);
      btn3.setOnClickListener(this);
      btn4.setOnClickListener(this);
      btn5.setOnClickListener(this);

     ...

public void onClick(View v) {
    switch (v.getId()) {
        case R.id.button0:
            Intent intent = new Intent(this,MainActivity.class);
            startActivity(intent);
            finish();
            break;
        case R.id.button1:
            dial.show();
            break;
