I've used layout inflater in my program. Everything is good in Android 4 but when use in android 2.2, the program terminates with a runtime error (force close).

Where is the problem?

Part of the code:

Log.i("Hossein", "1");
    
    inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    
    Log.i("Hossein", "2");
    
    View itemView = inflater.inflate(R.layout.drawer_list_item, parent,
            false);

    Log.i("Hossein", "3");

Layout code:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    style="?attr/spinnerDropDownItemStyle"
    android:layout_width="match_parent"
    android:layout_height="?attr/dropdownListPreferredItemHeight"
    android:background="?android:attr/activatedBackgroundIndicator"
    android:orientation="horizontal" >

    <ImageView
        android:id="@+id/icon"
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:adjustViewBounds="true" />

    <LinearLayout
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:gravity="center_vertical|left"
        android:orientation="vertical" >

        <TextView
            android:id="@+id/title"
            style="?attr/spinnerDropDownItemStyle"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:ellipsize="end"
            android:singleLine="true" />

        <TextView
            android:id="@+id/subtitle"
            style="?attr/spinnerDropDownItemStyle"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:ellipsize="end"
            android:singleLine="true"
            android:textAppearance="?attr/textAppearanceSmall" />
    </LinearLayout>

</LinearLayout>

该activatedBackgroundIndicator属性是在 API 级别 11 (Android 3.0) 中引入的。

将android:background="?android:attr/activatedBackgroundIndicator"根布局中的 替换为所有目标 API 级别上可用的内容，或使用替代资源机制在 11 之前的布局和其他布局之间变化。

请注意堆栈跟踪提到list_selector_background.xml- 您确定这是导致此堆栈跟踪的确切代码吗？
