我收到“错误膨胀类片段”。是因为我的 xml 文件中的错误吗？我觉得这可能与我正在使用的命名空间有关，但我不确定......

这是日志猫：

这是 XML 文件：

<LinearLayout 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"
tools:context=".Chartscreenactivity" >

<fragment
    class="com.shinobicontrols.charts.ChartFragment"
    android:id="@+id/chart"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

</LinearLayout>

以下是活动中的相关代码：

ChartFragment chartFragment =
                                    (ChartFragment) getFragmentManager().findFragmentById(R.id.chart);

                            // Get the a reference to the ShinobiChart from the ChartFragment
                            ShinobiChart shinobiChart = chartFragment.getShinobiChart();

虽然 ShinobiCharts 支持低至 API Level 9 (Gingerbread)，但 Fragments 仅在 API Level 11 中引入。因此您需要使用支持库。

从入门指南：

提示：要支持低至 API 9: Android 2.3 (Gingerbread) 的设备，您将需要使用SupportChartFragment而不是ChartFragment（在 XML 和 Java 源代码中）。此外，您将需要更改ShinobiQuickStartActivityto extendFragmentActivity而不是Activity并使用getSupportFragmentManager()方法而不是getFragmentManager(). 您的项目需要参考 Android 支持库来执行此操作。
