文字颜色没有变化TabWidget [英] The text color does not change TabWidget

问题描述

我试图修改 TabWidget 文本颜色，都没有成功，即使我已经尝试了不同的方式来改变它（见下文code）。

I'm trying to change the TabWidget text color, without success, even though I've tried different way to change it (see code below.)

我的背景标签是图像：

for (int i = 0; i < tabHost.getTabWidget().getTabCount(); i++) {
    tabHost.getTabWidget().getChildAt(i).setBackgroundColor(Color.TRANSPARENT); 
}

我不知道这是否产生某种冲突与我想现在做的事。

I do not know if this creates some sort of conflict with what I want to do now.

解决方法1：

main.xml中

....
    <TabWidget
        android:id="@android:id/tabs"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:background="@drawable/tabbarbackground"
        android:tabStripEnabled="false"            
        style="@style/TabText"
        /> ....

style.xml

style.xml

... <style name="TabText">
    <item name="android:textColor">@color/tab_text_color</item> </style> ....

tab_text_color.xml

tab_text_color.xml

<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_selected="true" android:textColor="#2daed9" />
    <item android:state_selected="false" android:color="#FFFFFF" />
</selector>

解决方案2

for (int i = 0; i < tabHost.getTabWidget().getTabCount(); i++) {
    tabHost.getTabWidget().getChildAt(i).setBackgroundColor(Color.TRANSPARENT);         
    RelativeLayout rl = (RelativeLayout) tabHost.getTabWidget().getChildAt(i);
    TextView textView = (TextView) rl.getChildAt(1);
    textView.setTextColor(R.color.tab_text_color);
}

tab_text_color.xml

tab_text_color.xml

<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_selected="true" android:textColor="#2daed9" />
    <item android:state_selected="false" android:color="#FFFFFF" /> </selector>

但既不解决方案工作。

but neither solution works.

但是，如果我更改第二个解决方案

However, if I change the second solution

textView.setTextColor (R.color.tab_text_color);

到

textView.setTextColor (Color.parseColor ("# ....")); 

它的工作原理，但这种解决方案并不改变文本的颜色，当我点击它。

It works, except this solution does not change the color of text when I click on it.

感谢。

推荐答案

我能够解决的，解决的办法是不优雅，但工程。我希望谁是有用的人：

I was able to solve, the solution isn't elegant but works. I hope who is usefull for somebody:

首先，我必须设置初始化颜色所有选项卡的TextView的：

First, I must set init color for the textview of all tabs:

for (int i = 0; i < tabHost.getTabWidget().getTabCount(); i++) {
    vg = (ViewGroup) getTabHost().getTabWidget().getChildAt(i);
    tv = (TextView) vg.getChildAt(1);
    tv.setTypeface(font);
    if (i == 0) {
        tv.setTextColor(Color.parseColor("#2daed9"));
        Currentab = 0;
    } else {
        tv.setTextColor(R.color.GrisOscuro);
    }
}

然后，我在重写方法设置ontabchanged，每个标签的变色。脉冲的标签是我（getTabHost（）。getCurrentTab（））。又是谁我preSS最后一个标签是Currentab。

And then, I set in the override method ontabchanged, the change color for each tab. The tab pulsed are i (getTabHost().getCurrentTab()). And the last tab who I press is Currentab.

getTabHost().setOnTabChangedListener(new OnTabChangeListener() {
    public void onTabChanged(String tabId) {
        int i = getTabHost().getCurrentTab();
        if (Currentab != i) {
            vg = (ViewGroup) getTabHost().getTabWidget()
                    .getChildAt(Currentab);
            tv = (TextView) vg.getChildAt(1);
            tv.setTextColor(R.color.GrisOscuro);

            Currentab = i;
            vg = (ViewGroup) getTabHost().getTabWidget()
                    .getChildAt(i);
            tv = (TextView) vg.getChildAt(1);
            tv.setTextColor(Color.parseColor("#2daed9"));
        }
    }
});

对不起，我的英语，我希望是为别人有用=）再见！ ; d
