如何以编程方式为所有 TextViews 设置文本颜色? [英] How to set text color for all the TextViews programatically?

问题描述

我正在动态创建 8 个 TextView 并将它们添加到我的布局中.我想设置他们的文字颜色.所以我在 color.xml 中声明了颜色代码，并将其设置为:

I am creating 8 TextViews dynamically and adding them in my layout. I want to set their text color. So I have declared the color code in my color.xml and I am setting it as:

txt1.setTextColor(getResources().getColor(R.color.off_white));

但我必须单独为所有 TextView 重复执行此操作.有没有办法可以为所有 TextViews 全局设置它.类似于我们在 jQuery 中可以做的事情，例如:

But I have to redundantly do this for all the TextViews individually. Is there a way wherein I can set it globally for all the TextViews. Something similar to what we can do in jQuery for example:

$('input[type="text"]').css('color','white');

推荐答案

您可以为此使用自定义 TextView.

You can use Custom TextView for that.

如图所示:

MyTextView mTxt = new MyTextView(getApplicationContext());  //Use MyTextView instead of TextView where you want to apply color
mTxt.setText("Some text");

您的自定义类 MyTextView 将类似于:

Your custom class MyTextView would be something like:

public class MyTextView extends TextView{

    public MyTextView(Context context) {
        super(context);
        // TODO Auto-generated constructor stub
        this.setTextColor(Color.GREEN); //change color as per your need here. 
    }
}

希望有帮助.
