解决方案

我知道这个问题是旧的。我在这里创办了答案：更改NumberPicker 的文本颜色

复制：

  

这code应该解决您的问题。您所遇到的问题是因为NumberPicker施工期间，它捕获的EditText文字颜色和分配到油漆，因此可以得出上面和下面搭配同色系编辑文本的数字。

 进口java.lang.reflect.Field中;公共静态布尔setNumberPickerTextColor（NumberPicker numberPicker，诠释颜色）
{
    最终诠释计数= numberPicker.getChildCount（）;
    的for（int i = 0; I＆LT;计数;我++）{
        查看孩子= numberPicker.getChildAt（I）
        如果（孩子的instanceof的EditText）{
            尝试{
                现场selectorWheelPaintField = numberPicker.getClass（）
                    .getDeclaredField（mSelectorWheelPaint）;
                selectorWheelPaintField.setAccessible（真）;
                （（油漆）selectorWheelPaintField.get（numberPicker））的setColor（彩色）。
                （（EditText上）子）.setTextColor（彩色）;
                numberPicker.invalidate（）;
                返回true;
            }
            赶上（NoSuchFieldException E）{
                Log.w（setNumberPickerTextColor，E）;
            }
            赶上（IllegalAccessException E）{
                Log.w（setNumberPickerTextColor，E）;
            }
            赶上（抛出：IllegalArgumentException五）{
                Log.w（setNumberPickerTextColor，E）;
            }
        }
    }
    返回false;
}
 

I have a ListView containing a TextView and a NumberPicker for each row. Whenever I start up the activity, the numbers of the NumberPicker are white (the same color as the background).

I tried applying a style as suggested here, here, and here ; to no avail.

Any other suggestions?

NumberPicker.xml

<NumberPicker 
    android:id="@+id/npMaterialAmount"
    android:layout_alignParentRight="true"
    android:layout_width="wrap_content"
    android:layout_height="75dp"
    style="@style/npColour"/>

-

Tried style 1:

<style name = "npColour" >
    <item name = "android:textColor">#000000</item>
</style>

-

Tried style 2:

<style name = "npColour" parent ="@android:style/Theme.Holo.Light">
</style>

... and the list goes on...

解决方案

I know the question is old. I founded the answer here: Change the text color of NumberPicker

Copy:

This code should solve your problem. The problem you are experiencing is because during the construction of NumberPicker it captures the EditText textColor and assigns to to a paint so it can draw the numbers above and below the edit text with the same color.

import java.lang.reflect.Field;

public static boolean setNumberPickerTextColor(NumberPicker numberPicker, int color)
{
    final int count = numberPicker.getChildCount();
    for(int i = 0; i < count; i++){
        View child = numberPicker.getChildAt(i);
        if(child instanceof EditText){
            try{
                Field selectorWheelPaintField = numberPicker.getClass()
                    .getDeclaredField("mSelectorWheelPaint");
                selectorWheelPaintField.setAccessible(true);
                ((Paint)selectorWheelPaintField.get(numberPicker)).setColor(color);
                ((EditText)child).setTextColor(color);
                numberPicker.invalidate();
                return true;
            }
            catch(NoSuchFieldException e){
                Log.w("setNumberPickerTextColor", e);
            }
            catch(IllegalAccessException e){
                Log.w("setNumberPickerTextColor", e);
            }
            catch(IllegalArgumentException e){
                Log.w("setNumberPickerTextColor", e);
            }
        }
    }
    return false;
}
