新的应用程序崩溃在启动，调试没有帮助 [英] New app crashing on start-up, debug not helping

问题描述

好吧，我试图调试我的code，使用DDMS，我不能qutie得到它的窍门，只是还没有。我想这是因为我的程序在启动崩溃。不管怎么说，我发现这哥们，他想不通我做错了什么。可有人请指出为什么我的应用程序在启动时崩溃？

Alright I tried debugging my code, using DDMS and I can't qutie get the hang of it just yet. I think it's because my program crashes on launch. Anyways, I showed this to a buddy and he can't figure out what I'm doing wrong. Can someone please point out why my app is crashing on start up?

推荐答案

您是要创建在全球区域的UI元素的问题。你可以有声明他们，如果你希望它是一个全局对象，但你不能实例化，直到你已经设置的内容视图后。例如：

The problem you have is you are creating your UI elements in the global area. You can declare them there if you want it to be a global object, but you can not instantiate them until after you have set the content view. For example:

    private RadioButton rockRB;
    private RadioButton paperRB;
    private RadioButton scissorsRB;
    private TextView result;



    @Override
    public void onCreate(Bundle savedInstanceState) {
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main); 
        // Content View Must be set before making UI Elements
        rockRB = (RadioButton)findViewById(R.id.radioRock);
        paperRB = (RadioButton)findViewById(R.id.radioPaper);
        scissorsRB = (RadioButton)findViewById(R.id.radioScissors);
        result =  (TextView)findViewById(R.id.result);
