Question

我有一个非常简单的应用程序，带有edittext，一个按钮和一个微调器。当我尝试创建一个新的Array Adapter时，我的程序崩溃了以下logcat：

我认为是因为这段代码：

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    locales.put("US", Locale.US);
    locales.put("Canada", Locale.CANADA);
    locales.put("French-Canada", Locale.CANADA_FRENCH);
    locales.put("Chinese", Locale.CHINA);
    List<String> lArr = new ArrayList<String>();
    for(String s : locales.keySet())
        lArr.add(s);
    Spinner spinner = (Spinner) findViewById(R.id.spinner);
    // Create an ArrayAdapter using the string array and a default spinner layout
    ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, R.id.spinner, android.R.layout.simple_spinner_item, lArr);
    // Specify the layout to use when the list of choices appears
    adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
    // Apply the adapter to the spinner
    spinner.setAdapter(adapter);
}

这应该是一件非常简单的事情。我偏离了android教程，创建了一个在代码中定义的数组，但似乎无法让它工作。

以下是xml文件中的代码：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context=".MainActivity" >

<EditText
    android:id="@+id/editText1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentTop="true"
    android:layout_centerHorizontal="true"
    android:layout_marginTop="95dp"
    android:ems="10"
    android:inputType="textMultiLine" />

<Button
    android:id="@+id/button1"
    style="?android:attr/buttonStyleSmall"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_below="@+id/editText1"
    android:layout_centerHorizontal="true"
    android:layout_marginTop="29dp"
    android:text="Button" />

<Spinner
    android:id="@+id/spinner"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_below="@+id/button1"
    android:layout_centerHorizontal="true"
    android:layout_marginTop="47dp" />

</RelativeLayout>

由于您使用的是用于微调器的xml布局，因此不支持它，或者您将错误的参数传递给数组适配器的构造函数。

而不是：

ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, R.id.spinner, android.R.layout.simple_spinner_item, lArr);

使用：

ArrayAdapter<String>adapter=new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item, array);

Spinner崩溃活动
