前言：TitlePageIndicator这个就是效果比较好。
一：定义布局文件simple_titles：
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<com.viewpagerindicator.TitlePageIndicator
android:id="@+id/indicator"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:padding="10dip" />
<android.support.v4.view.ViewPager
android:id="@+id/pager"
android:layout_width="fill_parent"
android:layout_height="0dp"
android:layout_weight="1" />
</LinearLayout> 二：代码中使用：
setContentView(R.layout.simple_titles);
mAdapter = new TestFragmentAdapter(getSupportFragmentManager());
mPager = (ViewPager)findViewById(R.id.pager);
mPager.setAdapter(mAdapter);
mIndicator = (TitlePageIndicator)findViewById(R.id.indicator);
mIndicator.setViewPager(mPager); 其中的mAdapter在定义的时候需要实现IconPagerAdapter中的getPageTitle方法
protected static final String[] CONTENT = new String[] { "This", "Is", "A", "Test", };
/**
* 定义tittle标题
*/
@Override
public CharSequence getPageTitle(int position) {
return TestFragmentAdapter.CONTENT[position % CONTENT.length];
} 三：可修改的属性：
<declare-styleable name="TitlePageIndicator">
<!-- 距离左侧和右侧的距离 -->
<attr name="clipPadding" format="dimension" />
<!-- 底边线和底边指示的颜色 -->
<attr name="footerColor" format="color" />
<!-- 底边线的高度 -->
<attr name="footerLineHeight" format="dimension" />
<!-- 指示样式选择，尖角还条形 -->
<attr name="footerIndicatorStyle">
<enum name="none" value="0" />
<enum name="triangle" value="1" />
<enum name="underline" value="2" />
</attr>
<!-- 指示的高度 -->
<attr name="footerIndicatorHeight" format="dimension" />
<!-- 效果就是指示变宽了 -->
<attr name="footerIndicatorUnderlinePadding" format="dimension" />
<!-- 文字tittle和底边指示的距离 -->
<attr name="footerPadding" format="dimension" />
<!-- 指示的位置，tittle的上面，还是tittle的下面 -->
<attr name="linePosition">
<enum name="bottom" value="0" />
<enum name="top" value="1" />
</attr>
<!-- 被选择tittle的颜色 -->
<attr name="selectedColor" />
<!-- 被选择的tittle显示是否加粗 -->
<attr name="selectedBold" format="boolean" />
<!-- 未被选择的tittle的颜色 -->
<attr name="android:textColor" />
<!-- 文字的大小 -->
<attr name="android:textSize" />
<!-- 下一个item距离上一个item多远时，上一个item开始移动消失 -->
<attr name="titlePadding" format="dimension" />
<!-- 指示和上边view的距离 -->
<attr name="topPadding" format="dimension" />
<!-- 整体的背景色 -->
<attr name="android:background" />
</declare-styleable> 四：使用自定义属性
1.布局中使用：
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<com.viewpagerindicator.TitlePageIndicator
android:id="@+id/indicator"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="#18FF0000"
android:padding="10dip"
android:textColor="#AA000000"
app:footerColor="#FFAA2222"
app:footerIndicatorHeight="3dp"
app:footerIndicatorStyle="underline"
app:footerLineHeight="1dp"
app:selectedBold="true"
app:selectedColor="#FF000000" />
<android.support.v4.view.ViewPager
android:id="@+id/pager"
android:layout_width="fill_parent"
android:layout_height="0dp"
android:layout_weight="1" />
</LinearLayout> 3.代码中使用：
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.simple_titles);
mAdapter = new TestFragmentAdapter(getSupportFragmentManager());
mPager = (ViewPager)findViewById(R.id.pager);
mPager.setAdapter(mAdapter);
TitlePageIndicator indicator = (TitlePageIndicator)findViewById(R.id.indicator);
mIndicator = indicator;
indicator.setViewPager(mPager);
final float density = getResources().getDisplayMetrics().density;
indicator.setBackgroundColor(0x18FF0000);
indicator.setFooterColor(0xFFAA2222);
indicator.setFooterLineHeight(1 * density); //1dp
indicator.setFooterIndicatorHeight(3 * density); //3dp
indicator.setFooterIndicatorStyle(IndicatorStyle.Underline);
indicator.setTextColor(0xAA000000);
indicator.setSelectedColor(0xFF000000);
indicator.setSelectedBold(true);
} 3.theme使用：
设置主题其中StyledIndicators可以自己随便定义，然后在配置文件中使用即可：
<style name="StyledIndicators" parent="@android:style/Theme.Light">
<item name="vpiTitlePageIndicatorStyle">@style/CustomTitlePageIndicator</item>
</style>
<style name="CustomTitlePageIndicator">
<item name="android:background">#18FF0000</item>
<item name="footerColor">#FFFF7F24</item>
<item name="footerLineHeight">1dp</item>
<item name="footerIndicatorHeight">2dp</item>
<item name="linePosition">top</item>
<item name="titlePadding">30dp</item>
<item name="footerIndicatorStyle">underline</item>
<item name="android:textColor">#AAFF7F24</item>
<item name="selectedColor">#FFFF7F24</item>
<item name="selectedBold">true</item>
</style> 使用主题:
<activity
android:name=".SampleTitlesStyledTheme"
android:label="Titles/Styled (via theme)"
android:theme="@style/StyledIndicators" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="com.jakewharton.android.viewpagerindicator.sample.SAMPLE" />
</intent-filter>
</activity> 五：在使用的时候，可以点击当前被选择的tittle，触发点击事件，只需要实现OnCenterItemClickListener即可：
public class SampleTitlesCenterClickListener extends BaseSampleActivity implements OnCenterItemClickListener {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.simple_titles);
mAdapter = new TestFragmentAdapter(getSupportFragmentManager());
mPager = (ViewPager)findViewById(R.id.pager);
mPager.setAdapter(mAdapter);
TitlePageIndicator indicator = (TitlePageIndicator)findViewById(R.id.indicator);
indicator.setViewPager(mPager);
indicator.setFooterIndicatorStyle(IndicatorStyle.Underline);
indicator.setOnCenterItemClickListener(this);
mIndicator = indicator;
}
@Override
public void onCenterItemClick(int position) {
Toast.makeText(this, "You clicked the center title!", Toast.LENGTH_SHORT).show();
}
} 也可以设置滑动监听：
mIndicator.setOnPageChangeListener(new ViewPager.OnPageChangeListener() {
@Override
public void onPageSelected(int position) {
Toast.makeText(SampleTitlesWithListener.this, "Changed to page " + position, Toast.LENGTH_SHORT).show();
}
@Override
public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {
}
@Override
public void onPageScrollStateChanged(int state) {
}
});
