添加單選按鈕時出現渲染問題

Question

無法理解錯誤。

但它構建的應用程序確定，我可以啓動它。

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


    <TextView 
     android:id="@+id/test" 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" 
     android:layout_marginLeft="16dp" 
     android:layout_marginRight="16dp"/> 

    <RadioGroup 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:layout_gravity="center_horizontal"> 

     <RadioButton 
      android:layout_width="wrap_content" 
      android:layout_height="wrap_content" 
      android:text="New RadioButton" 
      android:id="@+id/radioButton"/> 

     <RadioButton 
      android:layout_width="wrap_content" 
      android:layout_height="wrap_content" 
      android:text="New RadioButton" 
      android:id="@+id/radioButton2"/> 
    </RadioGroup> 


</LinearLayout> 

如何解決呢？

而且信息從我的gradle這個文件：

... 
compileSdkVersion 24 
buildToolsVersion "24.0.1" 

defaultConfig { 
    ... 
    minSdkVersion 16 
    targetSdkVersion 24 
    versionCode 1 
    versionName "1.0" 
...

Answer 1

在這裏看到： exception raised during rendering:Binary XML file line #-1:error inflating class<unknown> 通過SDK管理器安裝SDK 23和選擇它的預覽爲我工作。

Answer 2

<RadioGroup 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:layout_gravity="center_vertical" 
    android:orientation="vertical"> 

    <RadioButton 
     android:id="@+id/btn0" 
     android:layout_width="90dp" 
     android:layout_height="35dp" 
     android:button="@null" 
     android:gravity="center"/> 

    <RadioButton 
     android:id="@+id/btn1" 
     android:layout_width="90dp" 
     android:layout_height="35dp" 
     android:button="@null"
