Question

我在项目的player_small.xml文件夹中有一个名为res/layout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的自定义视图，其中包含来自超类FrameLayout的所有3个构造函数，它们都调用此方法：

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

当从另一个XML-Layout文件中使用它时，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，它会因此异常而崩溃：

我打开了R.class文件并查看了它，所有资源都存在。我该如何解决这个例外？

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非ID

来扩充视图
