Question

无法理解错误。

但是它可以构建应用程序，我可以启动它。

<?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>

如何解决？

来自我的gradle文件的信息：

...
compileSdkVersion 24
buildToolsVersion "24.0.1"

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

Answer 1

见这里： exception raised during rendering:Binary XML file line #-1:error inflating class<unknown> 通过SDK管理器安装SDK 23并选择它进行预览，对我来说很有用。

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"
        android:gravity="center" />

</RadioGroup>
