在进程的编辑文本中只获取数字而不是逗号

Question

我有这段代码可以从我的 EditText 输入中检测数字格式。

public class NumberTextWatcher implements TextWatcher {

    private DecimalFormat df;
    private DecimalFormat dfnd;
    private boolean hasFractionalPart;

    private EditText et;

    public NumberTextWatcher(EditText et)
    {
        df = new DecimalFormat("#,###.##");
        df.setDecimalSeparatorAlwaysShown(true);
        dfnd = new DecimalFormat("#,###");
        this.et = et;
        hasFractionalPart = false;
    }

    @SuppressWarnings("unused")
    private static final String TAG = "NumberTextWatcher";

    @Override
    public void afterTextChanged(Editable s)
    {
        et.removeTextChangedListener(this);

        try {
            int inilen, endlen;
            inilen = et.getText().length();

            String v = s.toString().replace(String.valueOf(df.getDecimalFormatSymbols().getGroupingSeparator()), "");
            Number n = df.parse(v);
            int cp = et.getSelectionStart();
            if (hasFractionalPart) {
                et.setText(df.format(n));
            } else {
                et.setText(dfnd.format(n));
            }
            endlen = et.getText().length();
            int sel = (cp + (endlen - inilen));
            if (sel > 0 && sel <= et.getText().length()) {
                et.setSelection(sel);
            } else {
                // place cursor at the end?
                et.setSelection(et.getText().length() - 1);
            }
        } catch (NumberFormatException nfe) {
            // do nothing?
        } catch (ParseException e) {
            // do nothing?
        }

        et.addTextChangedListener(this);
    }

    @Override
    public void beforeTextChanged(CharSequence s, int start, int count, int after)
    {
    }

    @Override
    public void onTextChanged(CharSequence s, int start, int before, int count)
    {
        if (s.toString().contains(String.valueOf(df.getDecimalFormatSymbols().getDecimalSeparator())))
        {
            hasFractionalPart = true;
        } else {
            hasFractionalPart = false;
        }
    }

}

然后在activity中调用。

JumlahTrx = (EditText)findViewById(R.id.editJumlah);
JumlahTrx.addTextChangedListener(new NumberTextWatcher(JumlahTrx));

如果我输入该字段，它将产生 5,000。我想要的是当我单击按钮时，值 5,000 变为 5000，然后插入到我的数据库中。因为我在我的数据库中设置了 INT。

任何帮助都会很好。谢谢

====================== 更新

添加此代码

String data = JumlahTrx.getText().toString();
data=data.replaceAll(",","");
int value=Integer.parseInt(data);
JumlahTrx.setText(value);

单击按钮将其保存到数据库时出现此错误

Answer 1

在将数据保存到数据库之前，您可以使用 replace 或 replaceAll 函数例如

String data = "5,000";
data= data.replaceAll(",","");

Int value = Integer.parseInt(data);

将该值存储到您的数据库

已更新

在你的 doInBackGround

改变

hashMap.put("JumlahTrx",params[2]);

到

 String a = params[2];
 a=a.replaceAll(",","");
 hashMap.put("JumlahTrx",a);

Answer 2

正如你所说我想要的是当我点击按钮时值 5,000 变成 5000。如果这只是要求，那么我有一个替代解决方案。试试这个

String a="5,00,000";

a=a.replaceAll(",","");

int num=Integer.parseInt(a);
