// ====== Using the Resources object =================================
// You might need to do this if your code is not in an activity.
// For example View has a protected mContext field you can use.
// In this case it's just 'this' since Activity is a context.
Context context = this;
// Get the Resources object from our context
Resources res = context.getResources();
// Get the string resource, like above.
cs = res.getText(R.string.styled_text);
tv = (TextView)findViewById(R.id.res1);

// Note that the Resources class has methods like getColor(),
// getDimen(), getDrawable() because themes are stored in resources.
// You can use them, but you might want to take a look at the view
// examples to see how to make custom widgets.
