尝试从 ActionBarSherlock 开始。下载库。使用最后更新设置 ADT，SDK 相同。
尝试进行简单的活动：
import com.actionbarsherlock.app.SherlockActivity;
import android.os.Bundle;
public class MainActivity extends SherlockActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
清单：
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="ru.alxr.usingsherlocksample"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="17" />
<application
android:allowBackup="true"
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/Sherlock.__Theme" >
<activity
android:name="ru.alxr.usingsherlocksample.MainActivity"
android:label="@string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
ADT 不允许将 android:theme="@style/Sherlock" 设置为红色 x。
所以，我在 logcat 中得到了预期的错误：
