Question: I would like to set a red colour text in my app, but I don't know how.

Please provide references. Thanks.

Answer: 
If you want it to set in XML layout then use:

```
<TextView 
 ...
 ...
 android:textColor="#FF0000" >
 </TextView>

```

If you want to set programmatically then use:

```
textview.setTextColor(Color.RED);
//textview must be defined in your class 

```
Create a [custom style resource](http://developer.android.com/guide/topics/resources/style-resource.html) which uses an [Android Theme](https://github.com/android/platform_frameworks_base/blob/master/core/res/res/values/themes.xml) as a parent then override the text colors as defined in the Android theme.xml. Reference this new style in your [AndroidManifest.xml's application tag](http://developer.android.com/guide/topics/manifest/application-element.html#theme).
