私は彼らのチュートリアル(最初のもの)からTeeChartの例を試してみようとしています. 以下のコードを実行すると、何らかの理由で UnsupportedOperationException が発生します。これが発生する理由について、誰でも助けを提供できますか。
以下、関連ファイルです。
AndroidManifest.xml
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.teeChart02"

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 );
}
}
生成される例外は次のとおりです。
