Change ViewPager Indicator color
提问by clever_trevor
I am trying to change the color of my ViewPager Indicator. I've read on herethat it uses a nine-patch, but I do not know where to find it. Here is my relevant Java code for the ViewPager creation.
我正在尝试更改 ViewPager 指示器的颜色。我在这里读到它使用了九个补丁，但我不知道在哪里可以找到它。这是我创建 ViewPager 的相关 Java 代码。
/**
* On swiping the ViewPager make respective tab selected
**/
private void initializeViewPagerListener() {
viewPager.setOnPageChangeListener(new ViewPager.OnPageChangeListener() {
@Override
public void onPageSelected(int position) {
// on changing the page
// make respected tab selected
actionBar.setSelectedNavigationItem(position);
}
@Override
public void onPageScrolled(int arg0, float arg1, int arg2) {
}
@Override
public void onPageScrollStateChanged(int arg0) {
}
});
}
/**
* Creates the tab portion of the ViewPager
*/
private void initializeTabs() {
viewPager = (ViewPager) findViewById(R.id.pager);
actionBar = getActionBar();
mAdapter = new TabsPagerAdapter(getSupportFragmentManager());
viewPager.setAdapter(mAdapter);
actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
// Adding Tabs
for (String tab_name : tabs) {
actionBar.addTab(actionBar.newTab().setText(tab_name)
.setTabListener(this));
}
}

Which ViewPager are you using? From support library or from which Android version?
您使用的是哪个 ViewPager？来自支持库还是来自哪个 Android 版本？
If it is android.support.v4.view.ViewPager you should only add one line of code:
如果是 android.support.v4.view.ViewPager 你应该只添加一行代码：
viewPager.getChildAt(0).setBackgroundResource(R.color.blue);
And also define blue color(or any other color chosen by you) in res/values/color.xml file:
并在 res/values/color.xml 文件中定义蓝色（或您选择的任何其他颜色）：
<color name="blue">#015599</color>
This should help.
这应该有帮助。

from the ViewPagerIndicator document from the below link:
来自以下链接的 ViewPagerIndicator 文档：
you can set this: Add the custom view below your view pager, the available attributes are: radius that specifies the radius of the circles and color to specify the color of them
你可以这样设置：在你的视图寻呼机下面添加自定义视图，可用的属性是：radius 指定圆的半径和 color 来指定它们的颜色
<com.efoad.views.ViewPagerIndicator
android:id="@+id/viewpager_indicator"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:layout_marginBottom="5dp"
android:padding="5dp"
custom:radius="3dp"
custom:color="@android:color/darker_gray" />

PagerTabStrip pagerTabStrip = (PagerTabStrip) findViewById(R.id.pager_title_strip);
pagerTabStrip.setTabIndicatorColor(Color.RED);

Write this line on your java class
indicator.setFillColor(Color.RED);
在你的java类上写下这一行
indicator.setFillColor(Color.RED);
