标签： android xml colors android-tabhost

我制作了一个tabhost。现在问题是我无法更改tabIndicator的背景和文本颜色。我已经看到了一些教程和我的问题的解决方案，但我无法理解他们如何使用它。我附上了应用的图片。它会让你清楚我的问题。

如何更改颜色？任何帮助或建议？

您应该通过样式化tabhost来实现此目的。 这两个答案可以指导您完成：

  1. Android remove space between tabs in tabwidget
  2. How to change the font size of tabhost in android

    3. 但你需要的是将一个主题应用于你的标签小部件，并将你选择的颜色/颜色状态drawable（如果你希望颜色在焦点上更改/按/等）添加到小部件的文本外观样式：< / p> 

        <style name="CustomTheme" parent="@android:style/Theme">
        <item name="android:tabWidgetStyle">@style/CustomTabWidget</item>
    </style>
    <style name="CustomTabWidget" parent="@android:style/Widget.TabWidget">
        <item name="android:textAppearance">@style/CustomTabWidgetText</item>
    </style>
    <style name="CustomTabWidgetText" 
    parent="@android:style/TextAppearance.Widget.TabWidget">
        <item name="android:color">@color/red</item>
    </style>

尝试使用如下

TabWidget tabWidget = getTabWidget();
TabHost tab = getTabHost();

tab.setOnTabChangedListener(new OnTabChangeListener() {

    public void onTabChanged(String arg0) {
        for (int i = 0; i < tab.getTabWidget().getChildCount(); i++) {
            tab.getTabWidget().getChildAt(i)
                        .setBackgroundResource(R.drawable.tab_selected); // unselected
        }
        tab.getTabWidget().getChildAt(tab.getCurrentTab())
                    .setBackgroundResource(R.drawable.tab_unselected); // selected

    }
});


Intent intent = new Intent(FromClass.this,
            ToClass.class);
TabSpec tabpiechartActivity = tab.newTabSpec("Name")
            .setIndicator(prepareIndicator("Name"))
            .setContent(intent);

，您的prepareIndicator将

private View prepareIndicator(String string) {
    View view = LayoutInflater.from(this).inflate(R.layout.customtab, null);
    // ImageView iv = (ImageView) view.findViewById(R.id.TabImageView);
    TextView tv = (TextView) view.findViewById(R.id.tabText);
    // iv.setImageResource(resId);
    tv.setText(string);
    return view;
}

你的res/layout/customtab xml是：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@drawable/tab_selected"
android:orientation="vertical" >

<TextView
    android:id="@+id/tabText"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:gravity="center"
    android:textColor="#ffffff"
    android:textSize="15dp" />

</LinearLayout>

res/drawable/tab_selected.xml 

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle" >
<gradient
    android:angle="225"
    android:endColor="#11029E"
    android:startColor="#DD000000" />
<corners
    android:bottomLeftRadius="0dp"
    android:bottomRightRadius="7dp"
    android:radius="0.1dp"
    android:topLeftRadius="0dp"
    android:topRightRadius="7dp" />

</shape>

res/drawable/tab_selected.tab_unselected.xml 

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle" >

<stroke
    android:width="1dp"
    android:color="#FFFFFFFF" />

<gradient
android:angle="225"
android:endColor="#0F7801"
android:startColor="#DD000000" />

<corners
    android:bottomLeftRadius="0dp"
    android:bottomRightRadius="7dp"
    android:radius="0.1dp"
    android:topLeftRadius="0dp"
    android:topRightRadius="7dp" />

</shape>

这是一个代码片段，用于自定义我的Tab Color和bg： - 

View view= createTabView(mContext,TAB_1_TAG);
mTabHost.addTab(mTabHost.newTabSpec(TAB_1_TAG).setIndicator(view), UpcomingTaskFragment.class, null);


private static View createTabView(final Context context, final String text) {
    View view = LayoutInflater.from(context).inflate(R.layout.dashboard_fragment_tabs_bg, null);
    TextView tv = (TextView) view.findViewById(R.id.dashboard_tab_heading);
    tv.setText(text);
    return view;
}

<?xml version="1.0" encoding="utf-8"?>


<TextView
    android:id="@+id/dashboard_tab_heading"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:background="@drawable/tab_text_bg"
    android:gravity="center"
    android:paddingBottom="@dimen/seven"
    android:paddingTop="@dimen/seven"
    android:shadowColor="@android:color/white"
    android:shadowDx="1.0"
    android:shadowDy="1.0"
    android:shadowRadius="2.5"
    android:textColor="@color/dashboard_tab_selector"
    android:textSize="@dimen/dashboard_tab_heading_text_size"
    android:textStyle="bold" />

对于父母，我使用以下选择器： - tab_bg_selector 

    <?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <!--  Active tab -->
    <item
        android:state_selected="true"
        android:state_focused="false"
        android:state_pressed="false"
        android:drawable="@android:color/white"
    />
    <!--  Inactive tab -->
    <item
        android:state_selected="false"
        android:state_focused="false"
        android:state_pressed="false"
        android:drawable="@drawable/tab_bg_unselected"
    />
</selector>

对于textview文本颜色，我使用： - 

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">

    <item android:state_selected="true" android:color="#0094e0"/>
    <item android:state_focused="true" android:color="#0094e0"/>
    <item android:state_pressed="true" android:color="#0094e0"/>
    <item android:color="#808080"/>

</selector>
