我在 Android Studio 中的 ActionBarActivity 有一些问题

Question

I'm trying a calendar apps in Android Studio.

I cloned it from github and now I have some problems.

I imported android.support.v7.app.ActionBarActivity but it keeps showing the message:

Cannot resolve symbol 'ActionBarActivity'

And there is also a warning message that says:

Can't start Git: D:\tests\simple\settings.gradle Probably the path to Git executable is not valid. Fix it.

How can I fix these problem? Please help me.

Answer 1

The ActionBarActivity is included in the AppCompat support Library .

To use it, you have to add the appcompat library in your project .

If you are using Android Studio, just add a dependency in your build.gradle

dependencies {
    // Support Libraries (it requires api 23 to compile)
    compile 'com.android.support:appcompat-v7:23.1.0'
}

If you are using Eclipse you can read this official link .

Also pay attention.
This class is deprecated.
Use AppCompatActivity instead.

Answer 2

If you have added your dependency to build.gradle , run a Gradle Sync. Also note the ActionBarActivity is deprecated, because it has been replaced by AppCompatActivity .

Answer 3

Android has deprecated ActionBar . Instead, try to use ToolBar which gives you more flexibility than ActionBar and extend AppCompactActivity instead of ActionbarActivity . This will solve your problem for sure.
