和主要活動的代碼是

import com.artfulbits.aiCharts.ChartView; 
import com.artfulbits.aiCharts.Base.ChartSeries; 
import com.artfulbits.aiCharts.Types.ChartDoughnutType; 
import com.artfulbits.aiCharts.Types.ChartPieType.LabelStyle; 

public class MainActivity extends Activity 
{ 
    /** Called when the activity is first created. */ 
    @Override 
    public void onCreate(Bundle savedInstanceState) 
    { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.main); 

     ChartView chartView = (ChartView) findViewById(R.id.chartView); 
     ChartSeries series = chartView.getSeries().get(0); 

     String[] labels = { "milk", "yeast", "flour", 
       "eggs", "butter", "salt", "water", "sugar" }; 
     int[] weights = {180, 12, 450, 100, 100, 10, 250, 250 }; 

     for (int i = 0; i < weights.length; i++) 
      series.getPoints().addXY(i, weights[i]).setLabel(labels[i]); 

     series.setAttribute(ChartDoughnutType.LABEL_STYLE, LabelStyle.OutsideColumn); 
     series.setAttribute(ChartDoughnutType.OPTIMIZE_POINTS, Boolean.FALSE); 
    } 
}

的main.xml文件

<?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" 
    > 

    <com.artfulbits.aiCharts.ChartView 
    android:id="@+id/chartView" 
    chart="@xml/chart" 
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent"/> 
</LinearLayout>

的完整的例子發表您的'main.xml'佈局，問題出在那裏。 –

確保您的ChartView類存在於包com.artfulbits.aiCharts中，如果它的庫確保已添加庫。 @ user3030365 – GrIsHu

嗨大衛我添加了我添加main.xml的代碼。請檢查 – user3030365

請確保你在你的源代碼，它有一個RES/xml目錄包含如下的xml文件。

chart.xml

<?xml version="1.0" encoding="utf-8"?> 
<ai:chart xmlns:ai="http://www.artfulbits.com/android/aiCharts"> 
    <ai:area /> 
    <ai:series type="Doughnut" showLabel="true"/> 
    <ai:title text="Doughnut ingredients"/> 
</ai:chart>

看到ArtfulBits
