java - 我的选项卡中的自定​​义 PNG 背景，Android 应用程序，(无法理解 logcat)

Question

虽然现在看来我有一个按钮失败，但目前没有背景，所以我将粘贴一些代码。

并且不知道为什么我遇到这个问题，所以我开始删除我试图从中获取背景的内容，现在我似乎无法理解现在的问题是什么。该应用程序刚刚崩溃了。在我解决了这个问题之后，主要问题是在所有选项卡中获得相同的背景。

如果您想要我的代码的任何其他部分，请告诉我。

这是我的 tabs.xml 中的一些 XML 代码:

    <Button
        android:id="@+id/bRingTaxi"
        android:layout_width="250dp"
        android:layout_height="250dp"
        android:layout_gravity="center"
        android:layout_y = "50dp"
        android:background= "@drawable/button_custom_callcab"
        android:textSize="40dp" />
</LinearLayout>

button_custom_callcab 出现在这里:

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:drawable="@drawable/callbutton_pressed"
          android:state_pressed="true" />
    <item android:drawable="@drawable/callbutton_pressed"
          android:state_focused="true" />
    <item android:drawable="@drawable/callbutton_un_pressed" />
</selector>

这是我尝试获取背景的部分。这是在 tabs.xml 文件中:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    android:background="@drawable/carbonfibre"
>

所以我希望你能帮助我理解这个logcat。如何获得正确的背景？

图像尺寸太大。减小大小并重试。
