请问这里的任何人请告诉我这里有什么问题吗？我也在AndroidMenifest.xml添加了ChartActivity。但错误不断回归。第

行也有一个错误

 @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        Intent intent = createIntent();
        startActivity(intent);

    }

Answer 1

将其放入AndroidManifest.Xml：

<activity android:name="org.achartengine.GraphicalActivity" />

Answer 2

听起来您的AndroidManifest.xml文件中没有此活动。

添加到您的清单文件中：

<activity
            android:name="org.achartengine.GraphicalActivity" >
        </activity>

Answer 3

您尚未在AndroidManifest.xml中声明GraphicalActivity活动。您必须记住，无论何时创建新活动，都应将活动添加到AndroidManifest文件中，如下所示：

<activity android:name=".newActivity">

添加：

<activity android:name="org.achartengine.GraphicalActivity" />

使用BarChartExample时意图给出错误
