android使用java代码设置textview、button等内容颜色

<pre name="code" class="html"><color name="mcolor">#cccccc</color>

//用与设置字体颜色
private Resources resources;
int selectColor;
private Button btn;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_dtdream_card_recharge);
resources = getBaseContext().getResources();  //核心代码
selectColor = resources.getColor(R.color.mcolor);
btn = (Button) findViewById(R.id.btn);
btn.setTextColor(selectColor);
}

setTextColor(DTPublicDyActivity.this.getResources().getColor(R.color.mcolor))
