按钮单击在软糖中不能正常工作

Question

我正在从edittext中获取文本并执行一些计算值，这些值在除JellyBean之外的每个api版本中都有效。问题是，当我在编辑文本中输入一个数字并按下计算按钮时它会工作，然后当我将该edittext的值更改为其他内容并再次按下计算时它不起作用。我需要重新启动应用程序才能使用它。我没有任何软糖设备可供测试，但我的客户提供了一个视频，我看到这个事实是真的。我现在该怎么办？

这是我在该按钮clicklistener

中执行的计算代码

try {
                double i = Double.parseDouble(startdate.getText().toString()) / 365;
                double j = 1 / i;
                double k = Math.pow(d3, j);
                double l = k - 1;
                double m = l * 100;
                annualroi = roundTwoDecimals(m);
                investmentyear.setText("Investment periode(Days):"
                        + startdate.getText().toString());

                annualizeroi.setText("Simple Annualized ROI(%):" + annualroi);
            } catch (Exception e) {
                e.printStackTrace();
            }

这是我的实际活动代码：

public class MainActivity extends Activity implements OnClickListener {

    EditText originalinvestment, returnedvalue, startdate;
    Button startpick, endpick, calculate, calculateannual;
    String posstartdate, postenddate;
    static final int DATE_PICKER_DIALOG_ID = 0;
    static final int DATE_PICKER_DIALOG_IDTWO = 1;
    Date dayofyearone;
    Date dayofyeartwo;
    double d1;
    double d;
    double d2;
    double d3;
    TextView tgainorloss, investmentyear, returninvestment, annualizeroi;
    double year;
    double gainorloss;
    double roi;
    double annualroi;

        // getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_RESIZE);
        setContentView(R.layout.activity_main);

        initializer();

        calculate.setOnClickListener(this);
        calculateannual.setOnClickListener(this);
    }

    private void initializer() {

        originalinvestment = (EditText) findViewById(R.id.etoriginalinvestment);

    }

                double k = Math.pow(d3, j);
                double l = k - 1;
                double m = l * 100;
                annualroi = roundTwoDecimals(m);
                investmentyear.setText("Investment periode(Days):"

    }

    double roundTwoDecimals(double d) {
        return Double.valueOf((new DecimalFormat("#.##")).format(d))
                .doubleValue();
    }

    public void getYearDifference() {
        try {

            if (!originalinvestment.getText().toString().contentEquals("")
                    && !returnedvalue.getText().toString().contentEquals("")) {

                d = Double.parseDouble(originalinvestment.getText().toString());
                d1 = roundTwoDecimals(Double.parseDouble(returnedvalue
                        .getText().toString()) - d);

                gainorloss = d1;
                roi = roundTwoDecimals(100D * (d1 / d));
                d3 = (roi / 100) + 1;

                tgainorloss.setText("Gain or loss investment($):" + gainorloss);
