更改TextView的背景色

1、android:background="@drawable/white"

  <TextView
  android:id="@+id/myTextView02"
  android:layout_width="fill_parent" 
  android:layout_height="wrap_content" 
  android:text="@string/str_textview02"
  android:background="@drawable/white"
  />

2、mTextView02.setBackgroundDrawable

Resources resources = this.getBaseContext().getResources();
		Drawable HippoDrawable = resources.getDrawable(R.drawable.white);
		mTextView01.setBackgroundDrawable(HippoDrawable);
