我想从3个EditText字段输入3个数据,它想要显示为条形图.

这是我的代码部分.给我一个解决这些错误的方法..

我试图使用此代码获取此条形图.但它没有用.我评论//错误点

   protected voID onCreate(Bundle savedInstanceState) {    super.onCreate(savedInstanceState);    setContentVIEw(R.layout.getfromdb);    final String[] mMonth = new String[] {            "Jan", "Feb" , "Mar", "Apr", "May", "Jun",            "Jul", "Aug" , "Sep", "Oct", "Nov", "Dec"        };    final EditText t1 =(EditText)findVIEwByID(R.ID.textVIEw1);    final EditText t2 =(EditText)findVIEwByID(R.ID.textVIEw2);    final EditText t3 =(EditText)findVIEwByID(R.ID.textVIEw3);    button btnChart = (button) findVIEwByID(R.ID.btnVIEw);      int x1 = Integer.parseInt(t1.getText().toString());    int x2 = Integer.parseInt(t2.getText().toString());    int x3 = Integer.parseInt(t3.getText().toString());     btnChart.setonClickListener(new OnClickListener() {            @OverrIDe            public voID onClick(VIEw v) {                openChart();            }               private voID openChart() {                    int x1 = Integer.parseInt(t1.getText().toString());                    int x2 = Integer.parseInt(t2.getText().toString());                    int x3 = Integer.parseInt(t3.getText().toString());                int[] x = { 0,1,2 };                int [] income = {x1 ,x2, x3};    //ERROR POINT                XYSerIEs incomeSerIEs = new XYSerIEs("pulse Rate");                                 XYSerIEs expenseSerIEs = new XYSerIEs("");                for(int i=0;i<x.length;i++){                                incomeSerIEs.add(i,income[i]);                }                XYMultipleSerIEsDataset dataset = new XYMultipleSerIEsDataset();                dataset.addSerIEs(incomeSerIEs);                dataset.addSerIEs(expenseSerIEs);                       XYSerIEsRenderer incomeRenderer = new XYSerIEsRenderer();                incomeRenderer.setcolor(color.rgb(130, 130, 230));                incomeRenderer.setFillPoints(true);                incomeRenderer.setlinewidth(2);                incomeRenderer.setdisplayChartValues(true);                XYSerIEsRenderer expenseRenderer = new XYSerIEsRenderer();                expenseRenderer.setcolor(color.rgb(220, 80, 80));                expenseRenderer.setFillPoints(true);                expenseRenderer.setlinewidth(2);                expenseRenderer.setdisplayChartValues(true);                        XYMultipleSerIEsRenderer multiRenderer = new XYMultipleSerIEsRenderer();                multiRenderer.setXLabels(0);                multiRenderer.setChartTitle("pulse Chart");                multiRenderer.setXTitle("pulse rate");                multiRenderer.setYTitle("Days");                multiRenderer.setZoombuttonsVisible(true);                              for(int i=0; i< x.length;i++){                    multiRenderer.addXTextLabel(i, mMonth[i]);                          }                       multiRenderer.addSerIEsRenderer(incomeRenderer);                multiRenderer.addSerIEsRenderer(expenseRenderer);                Intent intent = ChartFactory.getbarChartIntent(getBaseContext(), dataset, multiRenderer, Type.DEFAulT);                startActivity(intent);            }        });}private voID setlistadapter(SimpleCursorAdapter adapter) {    // Todo auto-generated method stub}

我在代码段中注释// ERROR POINT.
当我把这个值作为一个给出时

    int [] income = {60 ,40, 50};             //It should Be working

那么它应该工作..但我想把这些值使用EditText框.

解决方法:

尝试这一行

int x1 = Integer.parseInt(t1.getText().toString());
