Question

我在我的Android应用程序中添加了一个微调器，当我在模拟器中运行我的应用程序时崩溃了。在此之前它运行良好。这是我的微调器的代码...... 这是我的班级......

public void populateSpinners(){
    Spinner spinner = (Spinner) findViewById(R.id.spinner1);
    ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(
            this, R.array.planets_array, android.R.layout.simple_spinner_item);
    adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
    spinner.setAdapter(adapter);


    return;
}

这是我的string.xml ...

<string name="planet_prompt">Choose a planet</string>
<string-array name="planets_array">
    <item>Mercury</item>
    <item>Venus</item>
    <item>Earth</item>
    <item>Mars</item>
    <item>Jupiter</item>
    <item>Saturn</item>
    <item>Uranus</item>
    <item>Neptune</item>
</string-array>

这是我从这里“借来”的代码......

我在微调器初始化后添加了一个断点并在调试模式下运行应用程序。调试器运行正常并到达断点，没有错误。但是在断点之后，调试器会冻结并显示...

我看到了......

我读到这意味着我错过了Android源代码。它是否正确？为什么我需要Android源代码？ Android SDK不够用吗？还是有其他问题吗？我是Java / Android的新手（已经编程了大约一个星期了）而且我一直在搞乱我的事情所以请原谅我，如果这是一个“noob”问题。：D谢谢！

以下是我的DDMS中显示正在发生的错误的部分......

Answer 1

Eclipse尝试访问Android源代码以帮助您调试崩溃。在线有一些指令可以将源附加到Eclipse，但它们非常冗长，最好留作其他地方的练习（我在某些时候使用过http://android.opensourceror.org/2010/01/18/android-source/）。

如果您对崩溃本身有所帮助，可以从DDMS粘贴堆栈跟踪吗？（禁用断点）。

添加微调器后，Android应用程序崩溃
