AndroidStudio更换xml默认的布局
自从 AndroidStudio 到 2.3 了以后,新建一个 Activity,默认的布局就从以前的 LinearLayout
变成了 Google 强推的 ConstraintLayout
,但其实这个布局是可以被修改的。
在 Mac 上改默认布局(Windows可以自己找对应的目录),需要编辑这个文件:
/Applications/Android\ Studio.app/Contents/plugins/android/lib/templates/activities/common/root/res/layout/simple.xml.ftl
同时附赠一个 AndroidStudio
中使用 Kotlin
默认的依赖是依赖了 kotlin-jre
,而这个 jre 早就被改jetbrain
废弃了,修改 jre 为 jdk 可以编辑这个文件。
Applications/Android\ Studio.app/Contents/plugins/android/lib/templates/activities/common/kotlin_macros.ftl
下面是我自己使用的两个文件的内容,你可以直接复制走:
// simple.xml.ftl 文件的
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/root_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<Button
android:id="@+id/button"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Button"/>
</LinearLayout>
// kotlin_macros.ftl 文件的
<#-- Macro used to add the necessary dependencies to support kotlin to
an app build.gradle -->
<#macro addKotlinPlugins>
<#if generateKotlin>
<#compress>
apply plugin: 'kotlin-android'
apply plugin: 'kotlin-android-extensions'
</#compress>
</#if>
</#macro>
<#macro addKotlinDependencies>
<#if generateKotlin>${getConfigurationName("compile")} "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"</#if>
</#macro>
// TODO: <apply plugin /> Is adding the dependencies at the *end* of build.gradle
// TODO: The two macros above, addKotlinPlugins and addKotlinDependencies, are duplicating the work of addAllKotlinDependencies, when
// creating a new project (isNewProject == true). The only reason is the above bug on <apply plugin />
<#macro addAllKotlinDependencies>
<#if (language!'Java')?string == 'Kotlin'>
<#if !isNewProject>
<apply plugin="kotlin-android" />
<apply plugin="kotlin-android-extensions" />
</#if>
<#if !hasDependency('org.jetbrains.kotlin:kotlin-stdlib')>
<dependency mavenUrl="org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"/>
<merge from="root://activities/common/kotlin.gradle.ftl"
to="${escapeXmlAttribute(projectLocation)}/build.gradle" />
</#if>
</#if>
</#macro>
