现在我正在使用 android 中的一项 Web 服务。该 Web 服务有两个输入值，分别是 01/01/2012 和 07/07/2012。

单击调用按钮并提供这些作为输入值后，我的项目将显示一些条形图。它工作正常。这里我使用两个编辑文本框来获取这些输入值。

但我想使用日期选择器小部件而不是使用编辑文本框。所以我拖动了日期选择器小部件并做了一些代码。

但现在的问题是，输入值完全是数字和反斜杠，对吧？但是在日期选择器小部件中，它以字符和数字的组合显示输入值，但我只需要使用日期选择器小部件。

日期选择器小部件采用这种格式 dd-mm-yyyy 例如：- 01-jan-1990

但我需要将上述格式转换为 01/01/1990。这个怎么做？

请找到我的参考资料来源

条形图活动.java

int count;
RelativeLayout rltv;

@Override
    public void onCreate(Bundle savedInstanceState) 
{
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main1);

    final GraphicalView grfv = createIntent(); 

    RelativeLayout rltv = (RelativeLayout)findViewById(R.id.rlyot);
    rltv.addView(grfv);
}

public GraphicalView createIntent()
{
    rltv = (RelativeLayout)findViewById(R.id.rlyot);

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

    Bundle idata = getIntent().getExtras();
    if (idata !=null)
    {
        orderNo = idata.getStringArray("orderno");  
        freightRate = idata.getIntArray("freightrate");
        marginPercent = idata.getIntArray("marginpercent");
        count = idata.getInt("count");

        CategorySeries series = new CategorySeries("Order-FreightRate Graph");

        for ( int i = 0; i < count; i++)
        {
            series.add(orderNo[i], freightRate[i]);


            Thread th = new Thread();
            try 
            {
                Thread.sleep(2000);
                }
            catch (InterruptedException e) 
            {
                e.printStackTrace();
            }
        }


        XYMultipleSeriesDataset dataset = new XYMultipleSeriesDataset();
        dataset.addSeries(series.toXYSeries());

        XYSeriesRenderer renderer = new XYSeriesRenderer();
        renderer.setDisplayChartValues(true);

        //renderer.setChartValuesSpacing(1);

        XYMultipleSeriesRenderer mRenderer = new XYMultipleSeriesRenderer();
        mRenderer.addSeriesRenderer(renderer);

        mRenderer.setXLabelsColor(Color.WHITE);
        mRenderer.setYLabelsColor(0,Color.WHITE);

        mRenderer.setZoomButtonsVisible(true);

        mRenderer.setApplyBackgroundColor(true);
        mRenderer.setBackgroundColor(Color.parseColor("#000000"));

        mRenderer.setBarSpacing(0.7f);

    //  mRenderer.setChartTitleTextSize(20);
    //  mRenderer.setLabelsTextSize(25);
    //  mRenderer.setMarginsColor(Color.WHITE);

final GraphicalView grfv =  ChartFactory.getBarChartView(BarGraphActivity.this, dataset, mRenderer, Type.DEFAULT);
    return grfv;
    }
    return null;
    }
}

任何想法？

这个怎么样：

You keep the text fields and when the textfeild is selected a DateTime Picker dialog appears, and the textfield retains the datetime format.

final Calendar c = Calendar.getInstance();
mYear = c.get(Calendar.YEAR);
mMonth = c.get(Calendar.MONTH);
mDay = c.get(Calendar.DAY_OF_MONTH);
updateDisplay();

并在更新显示方法中：

private void updateDisplay() {
    checkdate.setText(
            new StringBuilder()
            // Month is 0 based so add 1
            .append(mMonth + 1).append("-")
            .append(mDay).append("-")
            .append(mYear).append(" "));
}

也添加到活动

@Override
protected Dialog onCreateDialog(int id) {
    // TODO Auto-generated method stub
    switch (id) {
    case DATE_DIALOG_ID:
        return new DatePickerDialog(this,
                mDateSetListener,
                mYear, mMonth, mDay);
 }
}
@Override
protected void onPrepareDialog(int id, Dialog dialog) {
    // TODO Auto-generated method stub
    switch (id) {
    case DATE_DIALOG_ID:
        ((DatePickerDialog) dialog).updateDate(mYear, mMonth, mDay);
        break;
    }
}
private DatePickerDialog.OnDateSetListener mDateSetListener =
    new DatePickerDialog.OnDateSetListener() {
    @Override
    public void onDateSet(DatePicker view, int year, int monthOfYear,
            int dayOfMonth) {
        // TODO Auto-generated method stub
        mYear = year;
        mMonth = monthOfYear;
        mDay = dayOfMonth;
        updateDisplay();
    }
};

并将焦点侦听器添加到文本字段

textfield1.setOnFocusChangeListener(new OnFocusChangeListener(){
        @Override
        public void onFocusChange(View v, boolean hasFocus) {
            // TODO Auto-generated method stub
            if(hasFocus){
                showDialog(DATE_DIALOG_ID);
            }
        }
    });

希望它是你需要的。
