Answer 1

首先把依赖改成

compile 'com.android.support:appcompat-v7:23.4.0'
compile 'com.android.support:design:23.4.0'

并在使用向量的 activity 中使用此代码。

static { AppCompatDelegate.setCompatVectorFromResourcesEnabled(true); }

Answer 2

只需在 build.gradle 中添加以下依赖项。这将解决您的问题。我正在使用 25.0.2 buildToolsVersion.

compile 'com.android.support:support-vector-drawable:25.3.0'
