模拟器上的运行时错误，但不是电话上的nullpointer异常

在try-catch循环中获得我的代码。它在我的手机上运行良好（三星Galaxy S3，但给Eclipse模拟器的运行时错误模拟器上的运行时错误，但不是电话上的nullpointer异常

错误出现后，我给该方法添加了颜色设置，并使用GradientDrawable作为我的按钮的背景（即使这似乎是工作在其他地点罚款）

我完全失去了这里......请看看，谢谢！生成错误 注

代码：我把一个断点“return super.onContextItemSelected（item）;”，在返回语句中/之后生成运行时错误。

@SuppressLint("NewApi") @SuppressWarnings("deprecation") 
@Override 
public boolean onContextItemSelected(MenuItem item) { 
    int timerLocation = findTimer(item.getGroupId()); 
    if (timerLocation > -1) 
    { 
     final MyCountDownTimer selectedFrag = this.myTimersList.get(timerLocation).fragmentRef; 
     switch (item.getItemId()) { 
      case R.id.timer_settings: 
       // Open timer specific options menu: 
       defaultSettingsMenu(selectedFrag); 
       return true; 

      default: 
       return super.onContextItemSelected(item); 
     } 
    } 
    else timerClickScreen.setText("ERROR: timer not found: " + String.valueOf(item.getGroupId()) + ", "+ String.valueOf(timerLocation));

什么是给你的错误？ – 2014-09-24 15:48:02

嗨佩德罗， 不确定。 当我进入上下文菜单并选择选项时，会发生错误。这会将defaultSettingsMenu加载到生成触发器的计时器（用于上下文菜单）。 这是测试之前，工作正常。但是，如果我尝试再次打开defaultSettingsMenu，则会生成空值点例外，但如果我更改颜色，则计时器确实响应正确（计时器颜色更改），但是如果我尝试再次打开defaultSettingsMenu， 这只发生在模拟器上，而不是在我的手机上（在那里运行得很好）。 这有帮助吗？ – EddyBee 2014-09-24 18:23:55

我建议你在defaultSettingsMenu的第一行放置一个断点，然后在Debug模式下运行该程序并逐行浏览它，看看是什么导致了这个问题。 – 2014-09-24 18:27:17

在SpinnerColorSelector类，我改变了：

view=inflater.inflate(android.R.layout.simple_spinner_dropdown_item, null);

要：

view=inflater.inflate(android.R.layout.simple_spinner_dropdown_item, parent, false);

和运行时错误消失了！它现在在模拟器上运行时没有问题......仍然奇怪的是，try-catch没有捕获到这个（可能是因为该对话框是在稍后的时间进行的）。无论如何，回到成为一个快乐的小狗！

这也摆脱了@SuppressLint（{“InflateParams”}）
