    n1 = (EditText) findViewById(R.id.num1);
    int no1 = Integer.parseInt(n1.getText().toString());
    n2 = (EditText) findViewById(R.id.num2);
    int no2 = Integer.parseInt(n2.getText().toString());
    message = (EditText) findViewById(R.id.message);
    String msg = message.getText().toString();
    settings.execSQL("CREATE TABLE IF NOT EXISTS settingtb(mob1 LONG,mob2 LONG,time VARCHAR,message VARCHAR(1000));");
    settings.execSQL("INSERT INTO settingtb VALUES('" + no1 + "','" + no2
            + "'," + time + ",'" + msg + "');");

如果 mob1，mob2 值小于 10 个值，则将数据插入数据库，如果超过 9 个值，则会出现 numberformat 异常

这是我的日志猫

您需要将这个整数变量更改为 long ，如下所示，

long no2 = Long.parseLong(n2.getText().toString().trim());

您以错误的方式插入值，您在 mob1 和 mob2 字段中插入字符串值，将其转换为数字，如下所示，

settings.execSQL("INSERT INTO settingtb VALUES(" + no1 + "," + no2
            + "," + time + ",'" + msg + "');");

'插入数值时无需添加。

同样，当您获取值时，您做错了，您正在访问整数变量中的所有内容??? 按如下方式更改，

c.moveToFirst();  
     if(c!=null)
     {
      do{
        long c1 = c.getColumnIndex("mob1");
        long c2 = c.getColumnIndex("mob2");
        String c3 = c.getColumnIndex("time");
        String c4 = c.getColumnIndex("message");

        s1 = c.getString(c1);
        s2 = c.getString(c2);
        s3 = c.getString(c3);
        s4 = c.getString(c4);

非常简单..实际上只需使用 Double 数据类型而不是 long

您的异常是否出现在这一行：“s3 = Integer.parseInt(c.getString(c3));”？

您可能超出了int范围：-2,147,483,648 到 2,147,483,647。尝试使用long来存储电话号码。

编辑：

替换这一行：

s3 = Integer.parseInt(c.getString(c3));

有了这个：

long s3Long = Integer.parseInt(c.getString(c3));
