按钮不工作在片段中没有错误？

我有一个旋钮和一个按钮的按钮应该打开一个新的活动，但它什么都不做 - 没有错误或强制关闭没有任何想法？

感谢您的帮助:)

您添加'addListenerOnButton（V）''中onCreateView（......）' –

需要在Fragment onCreateView(......)添加addListenerOnButton(v)，如：

@Override 

public View onCreateView(LayoutInflater inflater, ViewGroup container, 
     Bundle savedInstanceState) { 

    View v = inflater 
      .inflate(R.layout.fragment_breakfast, container, false); 

    addListenerOnButton(v); 
    ........... 
    .......... 
}

和编辑addListenerOnButton(v)像下面：

public void addListenerOnButton(View v) { 
    Button add = (Button) v.findViewById(R.id.button1); 
    add.setOnClickListener(new OnClickListener() 
    { 
     @Override 
     public void onClick(View v) { 
      switch (v.getId()) { 
      case R.id.button1: 
       Intent intent = new Intent(getActivity(), Review.class); 
       startActivity(intent); 
       break; 
      } 
     } 
    }); 
}

这已经完美工作的帮助表示感谢被窃听我很长一段时间看不到它！ – MalleyMob

在你onCreateView添加以下内容：

button = v.findViewById(R.id.button1); 
button.setOnClickListener(new OnClickListener(){ 
    @Override 
    public void onClick(View v) { 
     Intent intent = new Intent(getActivity(), Review.class); 
     startActivity(intent); 
    } 

});

兼评你的addListenerOnButton
