Android中设置TextView的颜色setTextColor

tv.setTextColor(Color.parseColor("#FFFFFF"));

tv.setTextColor(Color.WHITE);

tv.setTextColor(Color.rgb(255, 255, 255));
  //注意Color是大写C，不是color.holo_orange_dark,这样错误并没效果的

tv.setBackgroundResource(R.drawable.icon_bg_rectang_stroke);

这种方法也就是传入int color值，这个int不是R文件中自动分配的int值，所以要注意。这是Color类中的静态方法构造出来的颜色int值。

-------------------------------------------------------------------------------------

另一种方法：tv.setTextColor(this.getResources().getColor(R.color.red));

//通过获得资源文件进行设置。根据不同的情况R.color.red也可以是R.string.red或者R.drawable.red，

//当然前提是需要在相应的配置文件里做相应的配置，如：
#FF0000
< drawable name="red">#FF0000

< string name="red">#FF0000

注意上面的第三种方法，千万不能把自己定义的颜色直接当成参数，例如：

tv.setTextColor(R.color.red);这种情况会出现颜色错误！

--------------------------------------------------------------------

另一种方法：

Resources resource = (Resources) getBaseContext().getResources();
ColorStateList csl = (ColorStateList) resource.getColorStateList(R.color.my_color);
if (csl != null) {
    tv.setTextColor(csl);
}

这种方法是通过ColorStateList得到xml中的配置的颜色的。好多需要xml中配置的都要类似这样的映射xml文件。

还有种方法：

XmlResourceParser xrp = getResources().getXml(R.color.my_color);
try {
    ColorStateList csl = ColorStateList.createFromXml(getResources(), xrp);
    tv.setTextColor(csl);
} catch (Exception e) {
}

android中设置TextView的颜色有方法setTextColor，这个方法被重载了，可以传入两种参数。

public void setTextColor(int color) {
    mTextColor = ColorStateList.valueOf(color);
    updateTextColors();
}

public void setTextColor(ColorStateList colors) {
    if (colors == null) {
        throw new NullPointerException();
    }

    mTextColor = colors;
    updateTextColors();
}
