Android Wear setOnClickListener崩溃

我正在尝试为我的Sony Smartwatch 3编写一个应用程序，并且有一些Android编程的初学者知识。我已经在我的应用程序中添加了一个按钮，我正在尝试连接这个按钮。唯一的问题是，当我添加setOnClickListener时，我的应用程序崩溃并无法加载。当我删除两个箭头之间的代码时，应用程序将启动，并显示按钮，我可以单击它（当然不会发生任何事情）。所以我不确定我做错了什么，我搜索了又搜索，不幸的是没有找到答案。任何帮助都将不胜感激，android wear的提示和技巧将非常棒

super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_wear_start);
    final WatchViewStub stub = (WatchViewStub) findViewById(R.id.watch_view_stub);
    stub.setOnLayoutInflatedListener(new WatchViewStub.OnLayoutInflatedListener()
    {
        @Override
        public void onLayoutInflated(WatchViewStub stub)
        {
            mTextView = (TextView) stub.findViewById(R.id.text);
        }
    });
    Button startingButton = (Button) findViewById(R.id.starting_button);
--> startingButton.setOnClickListener(new View.OnClickListener()
    {

        @Override
        public void onClick(View v)
        {
            Toast.makeText(WearStart.this, "You clicked it!", Toast.LENGTH_LONG).show();
        }
--> });

将

按钮的单击事件

放入

onLayoutInflated（）

方法中，如下所示

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_home);
    final WatchViewStub stub = (WatchViewStub) findViewById(R.id.watch_view_stub);
    stub.setOnLayoutInflatedListener(new WatchViewStub.OnLayoutInflatedListener() {
        @Override
        public void onLayoutInflated(WatchViewStub stub) {
            mTextView = (TextView) stub.findViewById(R.id.text);
            imageButton=(ImageButton)stub.findViewById(R.id.imageButton);

            imageButton.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View view) {
                    //Toast.makeText(getApplicationContext(),"Haiii",Toast.LENGTH_LONG).show();

                    Intent toNext=new Intent(Home.this,SecondActivity.class);
                    startActivity(toNext);

                }
            });


        }
    });
}

这将对Android可穿戴应用程序的开发非常有用。

你确定你的startingButton id是正确的吗？当您试图设置OnClickListener时，是否确定它不是

null

？请粘贴您的布局（活动开始）和崩溃日志。感谢您的帮助和链接！不幸的是，我不能投票支持你的答案，但我在心里支持你@凯尔，你需要15个声望才能投票。谢谢你的评论
