Question

我正在尝试创建一个简单的应用程序，其中包含两个按钮，一个文本字段和两个用于练习的线性布局。我正在尝试为按钮创建资源ID。这是我的活动xml（activity_quiz.xml）：

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center"
android:orientation="vertical" >
<TextView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:padding="24dp"
    android:text="@string/question_text" />
<LinearLayout
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:orientation="horizontal" >
    <Button
        android:id="@+id/true_button"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/true_button" />
    <Button
        android:id="@+id/false_button"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/false_button"/>
</LinearLayout>

问题在于我所遵循的例子说你应该在R.id中看到这些ID但我在那里看不到它们。这是R.java的内部id类：

    public static final class id {
    public static final int action_bar=0x7f07001c;
    public static final int action_bar_activity_content=0x7f070014;
    public static final int action_bar_container=0x7f07001b;
    public static final int action_bar_overlay_layout=0x7f07001f;
    public static final int action_bar_root=0x7f07001a;

    public static final int disableHome=0x7f070008;
    public static final int dropdown=0x7f070013;
    public static final int edit_query=0x7f070030;
    public static final int end=0x7f07000c;
    public static final int expand_activities_button=0x7f070026;
    public static final int expanded_menu=0x7f07002c;
    public static final int home=0x7f070017;

    public static final int never=0x7f07000d;
    public static final int none=0x7f070009;
    public static final int normal=0x7f070000;
    public static final int progress_circular=0x7f070018;
    public static final int progress_horizontal=0x7f070019;
    public static final int radio=0x7f07002f;
    public static final int search_badge=0x7f070032;
    public static final int search_bar=0x7f070031;
    public static final int search_button=0x7f070033;

    public static final int search_src_text=0x7f070037;
    public static final int search_voice_btn=0x7f07003b;
    public static final int shortcut=0x7f07002e;
    public static final int showCustom=0x7f070007;
    public static final int showHome=0x7f070004;
    public static final int showTitle=0x7f070006;
    public static final int split_action_bar=0x7f07001e;
    public static final int submit_area=0x7f070039;
    public static final int tabMode=0x7f070002;
    public static final int title=0x7f07002b;
    public static final int top_action_bar=0x7f070020;
    public static final int up=0x7f070021;
    public static final int useLogo=0x7f070003;
    public static final int withText=0x7f070010;
}

我正在使用Android Studio并在第23版中编辑了活动xml并刚刚更新为rev 23.0.1如果还有其他任何可能有用的信息，请告知我们。

看起来您的资源ID名称是“true_button”和“false_button”但是，我不会为它们查看R类，因为它是每次构建项目时自动生成的。我建议清理你的项目并重建哪个应该为你的项目生成一个新的R类，并将这些id添加到R类。

我还推荐使用带有ADT插件的Eclipse，但我知道Android Studio是否对您更有利。我希望这会有所帮助，我之前遇到过这个问题并在几本书中阅读过。

编辑按钮属性后，未在R.id中创建的按钮的Android资源ID。我怎样才能解决这个问题？
