创建一个新的Android应用程序项目，取消第二步(配置项目)中的创建活动。

如果你的目标不是2。X版本，你可以设置你的最低SDK版本为4。X，然后创建项目。不会创建Appcompat V7库。

创建一个新的Android应用程序项目，取消第二步(配置项目)中的创建活动。

I'm new with Android and the project appcompat_v7 always be created when I create new Android application project makes me so uncomfortable. This is just a walk around. Choose Project Properties -> Android then at Library box just remove appcompat_v7_x and add appcompat_v7. Now you can delete appcompat_v7_x. Uncheck Create Activity in create project wizard doesn't work, because when creating activity by wizard the appcompat_v7_x appear again. My ADT's version is v22.6.2-1085508. I'm sorry if my English is bad.

Eclipse自动创建了appcompat_v7。因为Kitkat Api本身启动，它自动添加appcompat_v7和fragment_main.xml。

解决这些问题的最佳方法:

Firstly in project,Right click->properties->Android.There you can see the red marked appcompat placed in Reference. Click that and Remove it.Then Tick the right target name in Project Build Target. Delete fragment_main.xml and Appcompat file created in your Eclipse. Edit and change your activity_main.xml like these: <?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent"> <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="@string/hello_world" /> </RelativeLayout> In res/values/styles.xml: <resources> <style name="AppBaseTheme" parent="android:Theme.Light"> </style> <!-- Application theme. --> <style name="AppTheme" parent="AppBaseTheme"> </style> </resources> In res/values-v11/styles.xml you have to change like these: <resources> <style name="AppBaseTheme" parent="android:Theme.Holo.Light"> </style> </resources> In res/values-v14/styles.xml you have to change like these: <resources> <style name="AppBaseTheme" parent="android:Theme.Light"> </style> <style name="AppTheme" parent="AppBaseTheme"> </style> </resources> Change your menu/main.xml like these: <menu xmlns:android="http://schemas.android.com/apk/res/android" > <item android:id="@+id/action_settings" android:orderInCategory="100" android:showAsAction="never" android:title="@string/action_settings"/> </menu> Finally change your MainActivity.java like these: import android.app.Activity; import android.os.Bundle; public class MainActivity extends Activity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); } }

同样，创建新项目时也必须这样做

根据http://developer.android.com/guide/topics/ui/actionbar.html

ActionBar API最初是在Android 3.0 (API级别11)中添加的，但它们也可以在支持库中使用，以兼容Android 2.1 (API级别7)及以上。

简而言之，你所看到的自动生成项目模块化了将ActionBar添加到api 7-10的过程。
