android numberpicker 用于浮点数

我们应用程序的用户应该能够调整浮点数。目前，我用所有可能的值填充了 ArrayAdapter 并将其附加到微调器。

这个解决方案并没有真正满足我们的期望，因为旋转下拉框太高了。有没有更好的办法？我正在查看 Numberpicker - 但这似乎只适用于整数值。

有任何想法吗？

Thanks!

NumberPicker不仅仅是整数..甚至你可以使用Floats String etc.

see this http://developer.android.com/reference/android/widget/NumberPicker.html并阅读相关内容。

我曾经用过NumberPicker很久以前就这样了，在这里发帖可能会有一些用处：

    NumberPicker np;
    String nums[]= {"Select Fraction","1/64","1/32","3/64","1/16","5/64","3/32","7/64","1/8","9/64","5/32","11/64","3/16","13/64","7/32","15/64","1/4","17/64","9/32","19/64","5/16","21/64","11/32","23/64","3/8","25/64","13/32","27/64","7/16","29/64"};

            np = (NumberPicker) findViewById(R.id.np);

            np.setMaxValue(nums.length-1);
            np.setMinValue(0);
            np.setWrapSelectorWheel(false);
            np.setDisplayedValues(nums);
            np.setDescendantFocusability(NumberPicker.FOCUS_BLOCK_DESCENDANTS); 

你（们）能做到ArrayList任何数据类型并分配它。
