Android tabhost更改文本颜色样式

您可以按如下方式更改Tabhost文本的颜色。

tabHost.setOnTabChangedListener(new OnTabChangeListener() {

    @Override
    public void onTabChanged(String tabId) {

        for (int i = 0; i < tabHost.getTabWidget().getChildCount(); i++) {
            tabHost.getTabWidget().getChildAt(i).setBackgroundColor(Color.parseColor("#FF0000")); // unselected
            TextView tv = (TextView) tabhost.getTabWidget().getChildAt(i).findViewById(android.R.id.title); //Unselected Tabs
            tv.setTextColor(Color.parseColor("#ffffff"));
        }

        tabHost.getTabWidget().getChildAt(tabHost.getCurrentTab()).setBackgroundColor(Color.parseColor("#0000FF")); // selected
        TextView tv = (TextView) tabhost.getCurrentTabView().findViewById(android.R.id.title); //for Selected Tab
        tv.setTextColor(Color.parseColor("#000000"))

    }
});

编辑:

要在活动中最初设置文本颜色,可以在 onResume() 作用

TabHost tabhost = getTabHost();
    for(int i=0;i<tabhost.getTabWidget().getChildCount();i++) 
    {
        TextView tv = (TextView) tabhost.getTabWidget().getChildAt(i).findViewById(android.R.id.title);
        tv.setTextColor(Color.parseColor("#000000"));
    } 

这实际上可以使用XML主题来完成。这个 TabWidget 使用 android:textColorPrimary 对于所选选项卡和 android:textColorSecondary 对于未选中的。因此,您可以实现如下文本颜色更改:

在styles.xml中:

<style name="TabWidgetTheme" parent="AppTheme">
    <item name="android:textColorPrimary">@color/your_primary_color</item>
    <item name="android:textColorSecondary">@color/your_secondary_color</item>
</style>

在布局中:

<TabHost
    android:layout_height="match_parent"
    android:layout_width="match_parent"
    android:theme="@style/TabWidgetTheme"/>

注意 android:theme 不应直接在 选项卡小部件 而是包含 TabHost 或类似。

要更改选项卡的文本颜色,您需要获取视图,即设置为选项卡标题的TextView,您可以这样更改:

TabHost tabhost = getTabHost();
    for(int i=0;i<tabhost.getTabWidget().getChildCount();i++) 
    {
        TextView tv = (TextView) tabhost.getTabWidget().getChildAt(i).findViewById(android.R.id.title);
        tv.setTextColor(Color.parseColor("#000000"));
    } 

编辑:

另一种方法是为选项卡创建自定义视图。将选项卡添加到tabHost时

FragmentTabHost tabHost;

tabHost = (FragmentTabHost) findViewById(android.R.id.tabhost);
        tabHost.setup(this, getSupportFragmentManager(), R.id.frame);

//为每个选项卡创建customView 视图tabViewHome=创建TabView(tabHost.getContext(),“Home”,R.drawbable.ic_Home);

tabHost.addTab(tabHost.newTabSpec("Home").setIndicator(tabViewHome), HomeActivity.class, null);


private static View createTabView(final Context context, final String text, int iconId)
    {
            // inflate your layout here
        View view = LayoutInflater.from(context).inflate(R.layout.tab_layout, null);
        TextView tv = (TextView) view.findViewById(R.id.tab_tv_title);
        tv.setText(text);
            tv.setTextColor(Color.RED);
        ImageView iv = (ImageView) view.findViewById(R.id.tab_background_iv_icon);
        iv.setImageResource(iconId);
        return view;
    }

tab_layout.xml将如下所示:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/tabsLayout"
    android:layout_width="fill_parent"
    android:layout_height="40dip"
    android:gravity="center"
    android:orientation="vertical"
    android:padding="5dip" 
    android:background="#AAE1E1E1">

     <ImageView
        android:id="@+id/tab_background_iv_icon"
        android:layout_width="30dip"
        android:layout_height="30dip"
        android:contentDescription="@string/imgDesc"
        />

    <TextView
        android:id="@+id/tab_tv_title"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        //android:textColor="@drawable/tab_text_selector"
        android:textSize="8sp"
        android:textStyle="bold" />

</LinearLayout>

希望这有帮助。

我用这个解决方案:

private void setNewTab(final String tag, final String title, final Class<?> clazz, final Bundle bundle) {
    TabHost.TabSpec tabSpec = tabHost.newTabSpec(tag);
    tabSpec.setIndicator(InfoTabView_.build(getActivity()).bind(title, false));
    tabHost.addTab(tabSpec, clazz, bundle);
}

...

bundle = new Bundle();
bundle.putSerializable(FaqFragment.ARG_FAQS, infos.getFaq());
setNewTab("faq", "Faq", FaqFragment_.class, bundle);

...


@EViewGroup(R.layout.view_info_tab)
public class InfoTabView extends RelativeLayout {

    ....

    @Override
    public void setSelected(final boolean selected) {
        if (selected)
            titleTextView.setTextColor(selectedColor);
        else
            titleTextView.setTextColor(unselectedColor);
    }
}

覆盖setSelected是最干净的方法!
