无效的可绘制标签向量 [英] Invalid drawable tag vector

问题描述

我正在尝试在棒棒糖之前的设备上使用矢量可绘制对象.我按照指示进行了所有操作此处，但我仍然可以这次崩溃.

Im trying to use vector drawables on pre lollipop devices. I did all as instructed here but i still get this crash.

build.gradle:

build.gradle:

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.0.0-beta6'
    }
}
apply plugin: 'com.android.application'

repositories {
    maven { url 'http://maven.android-forever.com' }
    jcenter()
}

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.2"

    defaultConfig {
        applicationId "com.test.app"
        minSdkVersion 16
        targetSdkVersion 22
        versionCode 1
        versionName "1.0"
        vectorDrawables.useSupportLibrary = true
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:23.2.0'
    compile 'com.android.support:design:23.2.0'
    compile "de.greenrobot:eventbus:2.4.0"
    compile 'de.greenrobot:greendao:2.1.0'
    compile "com.af:android-utility:1.0.0.9"
    compile project(':volleyplus')
    compile project (':libvlc')
}

triangle.xml:

triangle.xml:

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:drawable="@drawable/triangle_v"/>
</selector>

triangle_v.xml

<vector xmlns:android="http://schemas.android.com/apk/res/android"
    android:height="100dp"
    android:width="100dp"
    android:viewportHeight="100"
    android:viewportWidth="100">

<path
    android:name="triangle"
    android:fillColor="#FF0000"
    android:pathData="m 50,0 l 50,100 -100,0 z"/>

</vector>

layout.xml

<ImageView
      android:layout_width="match_parent"
      android:layout_height="match_parent"
      android:background="@drawable/triangle"/>

我也尝试过app:srcCompat，在这种情况下，drawable不会显示.

I also tried app:srcCompat and in that case, drawable just dont show.

推荐答案

问题是我的活动不是扩展AppCompatActivity，而是常规的Activity.

The problem was that my activity wasn't extending AppCompatActivity but regular Activity.

在任何支持向量可绘制对象的文档/示例中都未指定

This is not specified in any documentation/example for support vector drawables
