此异常在 onCreate 方法的 setContentView(R.layout.xml_file) 行上抛出，在查看异常日志后我发现该行XML 中的 600 可能是造成这种情况的原因，这是包含 XML 中的行 600 的代码的一部分，这似乎导致了该错误:

          <LinearLayout
              android:id="@+id/zone_control"
              android:layout_width="wrap_content"
              android:layout_height="fill_parent"
              android:layout_gravity="center"
              android:gravity="center"
              android:orientation="vertical"
              android:padding="5dp"
              android:weightSum="7" >
            <Button                //this is the line 600
               android:id="@+id/one"
               android:layout_width="wrap_content"
               android:layout_height="wrap_content"
               android:layout_marginBottom="7dp"
               android:layout_weight="1"
               android:background="@drawable/num_buttons"
               android:clickable="false"
               android:paddingRight="10dp"
               android:paddingLeft="10dp"
               android:text="1"
               android:textColor="@android:color/white" />
              <!.. another three Buttons with the same statistics !..>
            </LinearLayout>

这是 num_buttons 可绘制对象:

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item 
    android:state_selected="true" 
    android:drawable="@drawable/remote_tv_number_unselected" />
<item 
    android:drawable="@drawable/remote_tv_number_selected" />
</selector>

这是remote_tv_number_selected:

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle">
    <corners android:radius="1dp"/>

    <gradient 
        android:startColor="#121212"
        android:centerColor="#212121"
        android:endColor="#353535"
        android:angle="30"/>

</shape>

只是一些翻转的颜色和另一个角度会给你 remote_tv_number_unselected

Answer 1

错误出现在 remote_tv_number_selected 文件的 android:angle 中，因为我将角度设置为 30 但似乎没有除了严格的 (0, 90, 180, 270) 之外，我不接受任何角度，所以我这样改变了它:

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle">
    <corners android:radius="1dp"/>

    <gradient 
        android:startColor="#121212"
        android:centerColor="#212121"
        android:endColor="#353535"
        android:angle="180"/>

</shape>
