推荐答案

确保已在app/build.gradle中的defaultConfig内添加了vectorDrawables.useSupportLibrary = true.

Make sure you have added vectorDrawables.useSupportLibrary = true inside defaultConfig in app/build.gradle.

喜欢

defaultConfig {
        vectorDrawables.useSupportLibrary = true
        ....
 }

编辑1 为了在API中支持小于21的vector，还应在setContentView之前的Activity的onCreate方法中添加它.

EDIT 1 In order to support vector in API less then 21. Also add this in onCreate method of Activity before setContentView.

AppCompatDelegate.setCompatVectorFromResourcesEnabled(true);
