Andorid --- File-＞ProjectStructure-＞SDK Location-＞Gradke Setting下面的Gradle JDK不可选择，选了之后也不生效，解决方案_sdk location 面板中没有gradle setttings

找到你项目工程下的.idea文件夹，里面有一个gradle.xml,具体内容如下：

<?xml version="1.0" encoding="UTF-8"?>

<project version="4">
<component name="GradleMigrationSettings" migrationVersion="1" />
<component name="GradleSettings">
<option name="linkedExternalProjectsSettings">
<GradleProjectSettings>
<option name="testRunner" value="GRADLE" />
<option name="distributionType" value="DEFAULT_WRAPPED" />
<option name="externalProjectPath" value="$PROJECT_DIR$" />
<option name="gradleJvm" value="1.8" />
<option name="modules">
<set>
<option value="$PROJECT_DIR$" />
<option value="$PROJECT_DIR$/app" />
</set>
</option>
<option name="resolveModulePerSourceSet" value="false" />
</GradleProjectSettings>
</option>
</component>
</project>

只需要修改<option name="gradleJvm" value="1.8" />修改到你想要的版本，并且这个版本是andoird自带的，比如

<option name="gradleJvm" value="11" />
