Question

我得到一个“错误膨胀类片段”。是由于我的xml文件中的错误？我觉得它可能与我正在使用的命名空间有关，但我不确定......

这是logcat：

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();

Answer 1

尽管ShinobiCharts支持API级别9（Gingerbread），但片段仅在API级别11中引入。因此您需要使用支持库。

从入门指南：

提示：要支持设备至API 9：Android 2.3（Gingerbread），您需要使用SupportChartFragment而不是ChartFragment（在XML和Java中）资源）。此外，您需要更改ShinobiQuickStartActivity以扩展FragmentActivity而不是Activity，并使用getSupportFragmentManager()方法而不是getFragmentManager()。您的项目需要引用Android支持库来执行此操作。
