Question

我在app中使用AppCompat的SearchView。在运行Android KitKat（4.4.4）的Samsung Galaxy Tab 3 Lite上运行应用程序时，我得到了各种NullPointerException：

调用setIconified(true)时，我收到以下异常：

12-08 14:58:31.124 15344-15344/com.algolia.instantsearch.examples.ecommerce E/AndroidRuntime: FATAL EXCEPTION: main
Process: com.algolia.instantsearch.examples.ecommerce, PID: 15344
java.lang.NullPointerException 
    at android.graphics.Canvas.drawLine(Canvas.java:931)
    at android.graphics.drawable.GradientDrawable.draw(GradientDrawable.java:538)
    at android.view.View.draw(View.java:14666)
    at android.view.View.draw(View.java:14566)
    ...

同样，只需打开该应用并点按SearchView即可展开该应用，结果如下：

    at android.view.View.draw(View.java:14566)

这是预期的吗？我在网上找不到任何关于此问题的报告。

我是否会错过在Android 4.4.4上使用AppCompat的SearchView的内容？
