Question

I am trying to create a menu option in which a user can select the color a textView can be displayed in. So for example the user selects red, selects a preview button which sets a textView background to red. Any suggestions would be much appreciated.

public class UserMenu extends Activity implements OnClickListener {
Button preview;
Spinner spinnerColor;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_user_menu);

        spinnerColor = (Spinner) findViewById(R.id.spinnerColorMenu);
        TextView Title = (TextView)findViewById(R.id.ViewModuleTitle);

        preview = (Button)findViewById(R.id.previewButton);
           preview.setOnClickListener(this);
    }

    public void onClick(View v)
    {
        String color = spinnerColor.getSelectedItem().toString();
        Title.setBackgroundResource(R.color.color);


    }
}

Layout

<LinearLayout 
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:orientation="vertical" >

    <TextView
        android:id="@+id/ViewModuleTitle"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:background="@color/darkBlue"
        android:paddingBottom="10dp"
        android:paddingLeft="10dp"
        android:paddingTop="10dp"
        android:text="@string/addModule"
        android:textColor="@color/white"
        android:textSize="22dp" />

    <TextView
        android:id="@+id/lableTextModuleCode"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/enterModuleCode"
        android:layout_marginLeft="10dp"
        android:paddingTop="10dp"
        android:paddingBottom="10dp"
        style="@style/textColor"/>

     <Spinner
        android:id="@+id/spinnerColorMenu"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:entries="@array/colorMenu"/>

     <Button
          android:id="@+id/previewButton"
          android:layout_width="150dp"
          android:layout_height="wrap_content"
          android:layout_marginBottom="10dp"
          android:onClick="previewButton"
          android:text="@string/addModule" />

     </LinearLayout>
