回答1:

For a switch, add this to your styles.xml file:

<style name="x" parent="@android:style/TextAppearance.Small">
    <item name="android:textColor">#33CCFF</item>
</style>

Two options:

add this to your layout XML file:

android:switchTextAppearance="@style/x"

add this to your Activity class after you've created an instance of your switch:
```
switchInstance.setSwitchTextAppearance(getActivity(), R.style.x);
```

_{Note: path to styles.xml file: Project Folder > res > values > styles.xml}

回答2:

When you create an instance of your EditText or TextView in your Activity code, you can set the TextColor, or Background Color for that matter, there.

Ex.

import android.graphics.Color; // add to top of your class

TextView x = (TextView)findViewById(R.id.y);

x.setTextColor(Color.parseColor("red")); // one way
x.setTextColor(Color.rgb(255, 0, 0)); // another way

x.setBackgroundColor(Color.parseColor("colorString"));
x.setBackgroundColor(Color.rgb(red int value, green int value, blue int value));
