Question

我正在尝试从他们的教程（第一篇）中学习TeeChart的一个例子。出于某种原因，当我运行下面的代码时，会导致发生UnsupportedOperationException。任何人都可以提供有关可能发生这种情况的任何帮助。

以下是相关文件。

的AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
          package="com.example.teeChart02"
          android:versionCode="1"
          android:versionName="1.0">
    <uses-sdk android:minSdkVersion="15"/>
    <application android:label="@string/app_name" android:icon="@drawable/ic_launcher">
        <activity android:name="MyActivity"
                  android:label="@string/app_name">
            <intent-filter>
                <action android:name="android.intent.action.MAIN"/>
                <category android:name="android.intent.category.LAUNCHER"/>
            </intent-filter>
        </activity>
    </application>
</manifest>

main.xml中

    <?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
              android:orientation="vertical"
              android:layout_width="fill_parent"
              android:layout_height="fill_parent"
              android:id="@+id/mylayout">
</LinearLayout>

MyActivity.java

package com.example.teeChart02;

import android.app.Activity;
import android.os.Bundle;
import android.widget.LinearLayout;
import com.steema.teechart.TChart;
import com.steema.teechart.drawing.Color;
import com.steema.teechart.styles.Bar;
import com.steema.teechart.styles.Series;

public class MyActivity extends Activity
{
    private TChart chart;

    @Override
    public void onCreate( Bundle savedInstanceState )
    {
        super.onCreate( savedInstanceState );
        setContentView( R.layout.main );

        LinearLayout ll = (LinearLayout) findViewById( R.id.mylayout );

        chart = new TChart( this );
        ll.addView( chart );

        Series bar = new Bar( chart.getChart() );
        chart.getAxes().getBottom().setIncrement( 1 );
        bar.add( 123, "Apples", Color.green );
        bar.add( 456, "Oranges", Color.red );
        bar.add( 321, "Kiwis", Color.yellow );
        bar.add( 78, "Bananas", Color.orange );
    }
}

生成的异常是：

Answer 1

请检查您是否在“项目属性 - ＆gt; Java构建路径 - ＆gt;订单和导出”选项卡中选择了TeeChart.Android.jar库

Answer 2

我正在和TeeChart一起工作，minSdkVersion为11，目标为13.一旦切换到12的minSdkVersion和15的目标，我就开始收到完全相同的错误。我还没有花时间弄清问题是哪个，但一旦我切换回11和13，问题就消失了
