Android:从.java设置EditText的默认提示颜色 [英] Android: Setting EditText's default hint color from .java

问题描述

所以我有一个LinearLayout和4个EditText-s，其中XML带有灰色的提示颜色.我有一个按钮，可以将新的EditText-s动态添加到LinearLayout.问题是当我使用setHint("text")时，它将使新创建的视图的提示颜色变为黑色.

So I have a LinearLayout and 4 EditText-s in it with grayish hint colors in XML. And I have button that dynamically adds new EditText-s to LinearLayout. The problem is when I use setHint("text") it makes hint color for new created views black.

也尝试过setHintTextColor()，但是它是通过设置自定义颜色来为我工作的唯一方法.是否可以通过setHintTextColor()设置默认的提示颜色?或某种方法在调用时会执行此操作?

Also tried setHintTextColor() but the only way it worked for me by setting custom color. Is there a default hint color that I can set by setHintTextColor()?? or maybe some method that does it when it's called?

代码如下:

private EditText createNewTextView(String text) {
    ++x;
    final ActionBar.LayoutParams lparams = new ActionBar.LayoutParams(ActionBar.LayoutParams.WRAP_CONTENT, ActionBar.LayoutParams.WRAP_CONTENT);
    final EditText editText = new EditText(this);
    editText.setLayoutParams(lparams);
    editText.setHint("Name" + x);
    editText.setHintTextColor(getResources().getColor(R.color.hintcolor));
    return editText;
}

p.s.我用一种新的颜色制成了一种叫做提示色"的颜色

p.s. I made new color in colors which is called hintcolor

我一直在寻找解决方案，但是没有什么对我有帮助，或者我只是不理解.我是android和编程方面的新手，请不要判断，请解释一下.非常感谢

I've been looking for solution, but there was nothing that would help me, or I just didn't understood it. I'm new at android and programming so don't judge please, just explain. Thanks a lot

推荐答案

可能为时已晚，但是为了其他有相同问题的人，我通过制定一种获取默认 textColorHint 的方法来解决了该问题. strong>.
它返回当前主题中指定的所有状态(禁用，聚焦，选择...)的提示文本的颜色.

It may be too late but for the sake of others who have the same problem, I solved it by making a method to get default textColorHint.
It returns the color of the hint text for all the states (disabled, focussed, selected...) that specified in the current theme.

int getHintTextColor(Context context) {
    int[] hintTextColor = new int[] { android.R.attr.textColorHint };
    int indexOfAttrTextColorHint = 0;
    TypedArray ta = context.obtainStyledAttributes(hintTextColor);
    int textColor = ta.getColor(indexOfAttrTextColorHint, 0xFF808080);
    ta.recycle();
    return textColor;
}

我希望这会有所帮助.
