问题描述
我的工作是与chartengine lib中绘制用户数据的应用程序。
我有一个标签的应用和我的图表绘图工作从装载到标签的活动地方，但并非如此。
我不知道为什么，如果有人能帮助我吗？
I'm working on an app that plots user data with a chartengine lib.I have a tab application and my chart plot works anywhere but not from activities that load to tabs.I wonder why and if anyone can help me?
本作品：
public class DataActivity extends Activity {
static final int SERIES_NR = 3;
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.data_form);
XYMultipleSeriesRenderer renderer = getTruitonBarRenderer();
myChartSettings(renderer);
Intent i = ChartFactory.getBarChartIntent(DataActivity.this, getTruitonBarDataset(), renderer, Type.DEFAULT);
startActivity(i);
}
private XYMultipleSeriesDataset getTruitonBarDataset() {
XYMultipleSeriesDataset dataset = new XYMultipleSeriesDataset();
final int nr = 11;
Random r = new Random();
ArrayList<String> legendTitles = new ArrayList<String>();
legendTitles.add("Sales");
legendTitles.add("Expenses");
legendTitles.add("age");
for (int i = 0; i < SERIES_NR; i++) {
CategorySeries series = new CategorySeries(legendTitles.get(i));
for (int k = 0; k < nr; k++) {
series.add(k+ r.nextInt() % 100);
}
dataset.addSeries(series.toXYSeries());
}
return dataset;
}
public XYMultipleSeriesRenderer getTruitonBarRenderer() {
XYMultipleSeriesRenderer renderer = new XYMultipleSeriesRenderer();
renderer.setAxisTitleTextSize(16);
renderer.setChartTitleTextSize(20);
renderer.setLabelsTextSize(15);
renderer.setLegendTextSize(15);
renderer.setMargins(new int[] { 30, 40, 15, 0 });
SimpleSeriesRenderer r = new SimpleSeriesRenderer();
r.setColor(Color.BLUE);
renderer.addSeriesRenderer(r);
r = new SimpleSeriesRenderer();
r.setColor(Color.RED);
renderer.addSeriesRenderer(r);
r = new SimpleSeriesRenderer();
r.setColor(Color.CYAN);
renderer.addSeriesRenderer(r);
return renderer;
}
private void myChartSettings(XYMultipleSeriesRenderer renderer) {
renderer.setChartTitle("achart engine by mahdi tajik");
renderer.setXAxisMin(0.5);
renderer.setXAxisMax(10.5);
renderer.setYAxisMin(0);
renderer.setYAxisMax(210);
renderer.addXTextLabel(1, "2010");
renderer.addXTextLabel(2, "2011");
renderer.addXTextLabel(3, "2012");
renderer.addXTextLabel(4, "2013");
renderer.addXTextLabel(5, "2013");
renderer.addXTextLabel(6, "2013");
renderer.addXTextLabel(7, "2012");
renderer.addXTextLabel(8, "20123");
renderer.addXTextLabel(9, "201223");
renderer.addXTextLabel(10, "2022213");
renderer.addXTextLabel(11, "20122223");
renderer.setYLabelsAlign(Align.RIGHT);
renderer.setBarSpacing(0.5);
renderer.setXTitle("Years");
renderer.setYTitle("Performance");
renderer.setShowGrid(true);
renderer.setGridColor(Color.GRAY);
renderer.setXLabels(0); // sets the number of integer labels to appear
}
}
但不会工作：
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.static_form);
initilizeUi();
}
private void plotWeekStatics(){
XYMultipleSeriesRenderer renderer = getTruitonBarRenderer();
myChartSettings(renderer);
Intent i = ChartFactory.getBarChartIntent(StaticActivity.this, getTruitonBarDataset(), renderer, Type.DEFAULT);
startActivity(i);
}
private XYMultipleSeriesDataset getTruitonBarDataset() {
XYMultipleSeriesDataset dataset = new XYMultipleSeriesDataset();
final int nr = 11;
Random r = new Random();
ArrayList<String> legendTitles = new ArrayList<String>();
legendTitles.add("Sales");
legendTitles.add("Expenses");
legendTitles.add("age");
for (int i = 0; i < SERIES_NR; i++) {
CategorySeries series = new CategorySeries(legendTitles.get(i));
for (int k = 0; k < nr; k++) {
series.add(k+ r.nextInt() % 100);
}
dataset.addSeries(series.toXYSeries());
}
return dataset;
}
public XYMultipleSeriesRenderer getTruitonBarRenderer() {
XYMultipleSeriesRenderer renderer = new XYMultipleSeriesRenderer();
renderer.setAxisTitleTextSize(16);
renderer.setChartTitleTextSize(20);
renderer.setLabelsTextSize(15);
renderer.setLegendTextSize(15);
renderer.setMargins(new int[] { 30, 40, 15, 0 });
SimpleSeriesRenderer r = new SimpleSeriesRenderer();
r.setColor(Color.BLUE);
renderer.addSeriesRenderer(r);
r = new SimpleSeriesRenderer();
r.setColor(Color.RED);
renderer.addSeriesRenderer(r);
r = new SimpleSeriesRenderer();
r.setColor(Color.CYAN);
renderer.addSeriesRenderer(r);
return renderer;
}
private void myChartSettings(XYMultipleSeriesRenderer renderer) {
renderer.setChartTitle("achart engine by mahdi tajik");
renderer.setXAxisMin(0.5);
renderer.setXAxisMax(10.5);
renderer.setYAxisMin(0);
renderer.setYAxisMax(210);
renderer.addXTextLabel(1, "2010");
renderer.addXTextLabel(2, "2011");
renderer.addXTextLabel(3, "2012");
renderer.addXTextLabel(4, "2013");
renderer.addXTextLabel(5, "2013");
renderer.addXTextLabel(6, "2013");
renderer.addXTextLabel(7, "2012");
renderer.addXTextLabel(8, "20123");
renderer.addXTextLabel(9, "201223");
renderer.addXTextLabel(10, "2022213");
renderer.addXTextLabel(11, "20122223");
renderer.setYLabelsAlign(Align.RIGHT);
renderer.setBarSpacing(0.5);
renderer.setXTitle("Years");
renderer.setYTitle("Performance");
renderer.setShowGrid(true);
renderer.setGridColor(Color.GRAY);
renderer.setXLabels(0); // sets the number of integer labels to appear
}
为什么在一个活动同code的工作不是在另一
我必须说，第二个code样品中加载到tabactivity。
Why does the same code work in one activity not in anotherI must say that in the second code sample it loads to a tabactivity.
推荐答案
我终于被我解决这个问题。
问题是我不会定义清单文件achartactivity是这样的：
i finally i solve the problem.the problem was i wont define achartactivity in manifest file like this:
<activity android:name="org.achartengine.GraphicalActivity"/>
和与添加这个我的应用程序正常工作。 ：）
and with adding this my app works correctly. :)
