单选按钮更改文本颜色

Question

I cant change the text color in my radiobutton:

  <RadioGroup
                        android:gravity="center"
                        android:layout_width="fill_parent"
                        android:layout_height="wrap_content"
                        android:orientation="horizontal"
                        android:color = "#000000"
                    >

                        <RadioButton 
                            android:id="@+id/contact_yes"
                            android:layout_width="wrap_content"
                            android:layout_height="wrap_content"
                            android:color = "#000000"
                            android:text="@string/yes" />

                        <RadioButton 
                            android:id="@+id/contact_no"
                            android:layout_width="wrap_content"
                            android:layout_height="wrap_content"
                            android:color = "#000000"
                            android:text="@string/no" />
                </RadioGroup>

It's always white, and I would like to change to black?

Thank you in advance

android:layout_height="wrap_content"
android:color = "#000000"
android:text="@string/yes" />

Try this:

<RadioButton 
android:id="@+id/contact_yes"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textColor="#000000"
android:text="@string/yes" />

Answer 4

You can use android:textColor method to do that.

An example is android:textColor="#00000000"

In #00000000 the two left bit is transparent bit . #00 ( transparent ) 00 ( Red Color) 00 ( Green color) 00 ( Blue color). they are hex.

To more details about transparent bit see Set transparent background .
