super.onCreate(savedInstanceState);
setContentView(R.layout.main);

mTextView01 = (TextView) findViewById(R.id.myTextView01);
mTextView01.setText("我是应用Drawable背景色的戴维文本。");

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