在支持库(23.4.0)的帮助下,无法在Android API 19中正确加载Vector Drawable

概述最近,我想使用Vector Drawable来管理所有图标. Vector Drawable在 Android API 21上运行良好,但当我尝试在我的一个测试设备[Amazon KFTHWI Android 4.4.3 API 19]上使用它时,根本无法加载所有图标！ 我按照提示Here和Here.但它仍然无法正常工作…. 这是我的配置： 在项目gradle脚本文件中： buildscript 最近,我想使用Vector Drawable来管理所有图标. Vector Drawable在 Android API 21上运行良好,但当我尝试在我的一个测试设备[Amazon KFTHWI AndroID 4.4.3 API 19]上使用它时,根本无法加载所有图标！

我按照提示Here和Here.但它仍然无法正常工作….

这是我的配置：

在项目gradle脚本文件中：

buildscript {  repositorIEs {    jcenter()  }  dependencIEs {    classpath 'com.androID.tools.build:gradle:2.1.0'    classpath ...  }}

所以我的gradle插件版本应该是2.0

在主模块gradle脚本文件中：

androID{    ...    defaultConfig{        ...        vectorDrawables.useSupportlibrary = true        ...    }}dependencIEs{    ...    compile 'com.androID.support:appcompat-v7:23.4.0'    compile 'com.androID.support:grIDlayout-v7:23.4.0'    ...}

此主模块包含该应用程序.
我编译grIDlayout-v7库的原因是因为我在应用程序中使用了一些GrIDlayouts.

这是我的实施：

因为我需要根据收到的数据生成一些视图,所以我在java代码中设置了图像源.

ImageVIEw icon = new ImageVIEw(this);icon.setimageResource(R.drawable.ic_lock_black_24dp);

ic_lock_black_24dp.xml是从Vector Asset Studio中的Material Icon库生成的.

我的期望：

我相信我的主模块gradle脚本文件中的配置将阻止AndroID Studio生成Pngs for Vectors,并允许AndroID在运行时直接生成Drawables for Vectors.

但我只是部分正确…我的配置实际上阻止了AndroID Studio在构建时生成Png.但我的旧AndroID设备[API 19]无法从矢量生成Drawables !!所以现在应用程序中没有图标……

以下是例外情况：[亚马逊KFTHWI AndroID 4.4.3 API 19]

可以肯定的是,如果我不使用AppCompat支持库,所有图标都会很好用,但我知道这是因为AndroID Studio在构建时会生成Png.我甚至可以在APK中找到那些Png.

我的问题：

现在,我仍然希望从旧的AndroID设备中的Vector Drawable中受益,这意味着我仍然试图避免使用Png …有人可以给我一些提示或者告诉我在哪些步骤中我做错了什么？

解决方法 你必须说新的AppCompatimageVIEw(这个).手动创建视图时,必须添加AppCompat前缀. 总结
