我正在为常用的 UI 元素使用片段。实现了一个简单的 POC 来检查并且它的工作很酷。但是当我整合到我的主要项目时，它会给出运行时错误（崩溃）

这是我的 Androidmainfiest.xml

 <activity
            android:name="com.draw.map.TestActivity"
            android:label="@string/title_activity_test" >
             <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>

我的片段 xml：fragment_text_view_bottom_slider.xml

在我的项目中包含其他库文件：* facebook android SDK * google play service * android support jar 4

谢谢你的时间

检查您的导入语句。

正如您所说，您的 MIN SDK 版本是 8。

论文陈述将不起作用；

import android.app.Fragment;
import android.app.FragmentManager;
import android.app.FragmentTransaction;

要从 SDK vesion 支持 Fragment 为 8，您需要导入这些语句

import android.support.v4.app.Fragment;
    import android.support.v4.app.FragmentManager;
    import android.support.v4.app.FragmentTransaction;
