如何在android中一個個顯示條形圖？

現在我已經在android中使用AchartEngine庫創建了條形圖。如何在android中一個個顯示條形圖？

這裏我的問題是，

得到啓動模擬器後，我的應用程序是顯示棒形圖瞬間，但我需要的是通過展示各個one.Which一個酒吧每個指條應該要一個接一個地可見。

如何做到這一點？

請提出建議？

請找我的消息來源參考

MainActivity.java

public class MainActivity extends Activity { 

Button btn_result; 

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

    btn_result = (Button)findViewById(R.id.button1_invoke); 
    btn_result.setOnClickListener(new View.OnClickListener() 
    { 

    @Override 
    public void onClick(View v) { 

    Intent intnt = new Intent(MainActivity.this,Result_BarActivity.class); 
      startActivity(intnt); 

     } 
    }); }}

Result_BarActivity.java

public class Result_BarActivity extends Activity 
{ 
RelativeLayout rltv; 

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

    final GraphicalView grfv =createIntent(); 

    RelativeLayout rl=(RelativeLayout)findViewById(R.id.RelativeLayout_ID); 
    rl.addView(grfv); 
    } 

public GraphicalView createIntent() 
{ 

    rltv = (RelativeLayout)findViewById(R.id.RelativeLayout_ID); 

    String[] titles = new String[] { "Order's profit of the year", " " }; 

    List<double[]> values = new ArrayList<double[]>(); 

    values.add(new double[] { 7, 2, 5, 8 }); 
    values.add(new double[] {}); 

    int[] colors = new int[] { Color.BLUE, Color.WHITE}; 

    XYMultipleSeriesRenderer renderer = buildBarRenderer(colors); 
    renderer.setOrientation(Orientation.HORIZONTAL); 

    setChartSettings(renderer, "Profit for the year 2012", " ", " ",0,10, 0,10, Color.GRAY, Color.LTGRAY); 

    renderer.setXLabels(1); 
     renderer.addXTextLabel(0.75, "ord1"); 
    renderer.addXTextLabel(1.75, "ord2"); 
    renderer.addXTextLabel(2.75, "ord3"); 
    renderer.addXTextLabel(3.75, "ord4"); 
    renderer.setPanEnabled(true, false); 

    int length = renderer.getSeriesRendererCount(); 

    for (int i = 0; i < length; i++) 
    { 
     SimpleSeriesRenderer seriesRenderer = renderer.getSeriesRendererAt(i); 
     seriesRenderer.setDisplayChartValues(true); 
    } 

    final GraphicalView grfv = ChartFactory.getBarChartView(Result_BarActivity.this, buildBarDataset(titles, values), renderer,Type.DEFAULT); 
    return grfv; 

/* ChartFactory.getBarChartIntent(this, buildBarDataset(titles, values), renderer,Type.DEFAULT);*/ 
} 

protected XYMultipleSeriesRenderer buildBarRenderer(int[] colors) 
{ 

// creates a SeriesRenderer and initializes it with useful default values as well as colors 

    XYMultipleSeriesRenderer renderer = new XYMultipleSeriesRenderer(); 

    renderer.setAxisTitleTextSize(15); 
    renderer.setChartTitleTextSize(20); 
    renderer.setLabelsTextSize(15); 
    renderer.setLegendTextSize(15); 

    int length = colors.length; 

    for (int i = 0; i < length; i++) 
    { 
     SimpleSeriesRenderer r = new SimpleSeriesRenderer(); 
     r.setColor(colors[i]); 
     renderer.addSeriesRenderer(r); 
    } 
    return renderer; 
    } 


protected void setChartSettings(XYMultipleSeriesRenderer renderer, String title, String xTitle, 
String yTitle, double xMin, double xMax, double yMin, double yMax, int axesColor,int labelsColor) 
{ 
// sets lots of default values for this renderer 

renderer.setChartTitle(title); 
renderer.setXTitle(xTitle); 
renderer.setYTitle(yTitle); 

renderer.setXAxisMin(xMin); 
renderer.setXAxisMax(xMax); 

renderer.setYAxisMin(yMin); 
renderer.setYAxisMax(yMax); 

renderer.setAxesColor(axesColor); 
renderer.setLabelsColor(labelsColor); 

renderer.setApplyBackgroundColor(true); 
renderer.setBackgroundColor(Color.MAGENTA); 
} 

protected XYMultipleSeriesDataset buildBarDataset(String[] titles, List<double[]> values) 
{ 
// adds the axis titles and values into the data-set 

XYMultipleSeriesDataset dataset = new XYMultipleSeriesDataset(); 
int length = titles.length; 

for (int i = 0; i < length; i++) 
{ 
    CategorySeries series = new CategorySeries(titles[i]); 
    double[] v = values.get(i); 
    int seriesLength = v.length; 

    for (int k = 0; k < seriesLength; k++) 
    { 
     series.add(v[k]); 
    } 
    dataset.addSeries(series.toXYSeries()); 
    } 
    return dataset; 
}}

的main.xml

<RelativeLayout 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" > 

<Button 
    android:id="@+id/button1_invoke" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:layout_alignParentTop="true" 
    android:layout_centerHorizontal="true" 
    android:layout_marginTop="195dp" 
    android:text="Invoke barchart" /> 

</RelativeLayout>

result_barchart.xml

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

</RelativeLayout>

在此先感謝...

您可以使用動態圖中的情節是指保持在發送特定的時間和數據repaint它

從其他功能發送數據到value列表

0123在 update()功能

int i = 0; 
While(true) 
{ 
    int[] series ={1,2,1,3,4,5,3,2,1,} // ex: your input data to be ploted 
    Thread.sleep(300000); //aprox. 5minutes delay 
    update(series[i]); 
}

添加數據

update(int newval) 
{ 
    value.add(newval); 
}

此repaint圖表後
