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);

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
