You are probably using an older version of the appcompat library. Can you show the import statements that this class uses?

您可能正在使用旧版本的 appcompat 库。你能展示这个类使用的导入语句吗？

Based on the newer version of appcompat, use

基于较新版本的 appcompat，使用

import android.support.v7.app.ActionBarDrawerToggle;

instead of

代替

import android.support.v4.app.ActionBarDrawerToggle;

Also, reference the new version of appcompat in build.gradle

另外，在 build.gradle 中引用新版本的 appcompat

dependencies {
    compile 'com.android.support:appcompat-v7:21.0.+'
}

Try to rebuild the project. If still that doesn't work try link https://developer.android.com/reference/android/support/v4/app/ActionBarDrawerToggle.html. This issue is caused basically due to the older version of appcompact library.

尝试重建项目。如果仍然不起作用，请尝试链接 https://developer.android.com/reference/android/support/v4/app/ActionBarDrawerToggle.html。此问题主要是由于旧版本的 appcompact 库引起的。
