java - 加载自定义 Android View 时出错 : Resources$NotFoundException: Resource ID #0x7f060007 type #0x12 is not valid

Question

我的项目的 res/layout 文件夹中有一个名为 player_small.xml 的 XML 文件:

<GridLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:id="@+id/player_small"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:rowCount="3"
        android:columnCount="4">

<ImageButton
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:id="@+id/player_small_play"
        android:layout_gravity="center"
        android:layout_row="0"
        android:layout_rowSpan="2"
        android:layout_column="0"
        android:src="@drawable/play"/>

<ImageButton
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/next"
        android:id="@+id/player_small_next"
        android:layout_gravity="center"
        android:layout_row="0"
        android:layout_rowSpan="2"
        android:layout_column="1"/>

<TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Title"
        android:textStyle="bold"
        android:textSize="@dimen/defaultFontSize"
        android:id="@+id/player_small_title"
        android:layout_gravity="center_vertical|left|right"
        android:layout_row="0"
        android:layout_column="3"/>

<Space
        android:layout_width="30px"
        android:layout_height="10px"
        android:layout_row="2"
        android:layout_column="2"/>

<TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Artist"
        android:textSize="@dimen/defaultFontSize"
        android:id="@+id/player_small_artist"
        android:layout_gravity="center_vertical|left|right"
        android:layout_row="1"
        android:layout_column="3"/>
</GridLayout>

然后，我定义了一个名为 SmallPlayerView 的自定义 View ，其中包含来自父类(super class) FrameLayout 的所有 3 个构造函数，所有构造函数都调用此方法:

protected void initSmallPlayerView ()
{
    View view = inflate(getContext(), R.id.player_small, null);
    addView(view);
}

当从另一个 XML 布局文件使用它时，InteliJ IDEA 可以正确显示该类，但是当我在手机或模拟器上启动它时，它会崩溃并出现以下异常:

我已经打开了R.class 文件并查看了它，所有资源都存在。我该如何解决这个异常？

Answer 1

您必须将代码更改为:

{
    View view = inflate(getContext(), R.layout.player_small, null);
    addView(view);
}

您可以使用布局属性而不是 id 来膨胀 View
