# MagicIndicator
A powerful, customizable and extensible ViewPager indicator framework. As the best alternative of ViewPagerIndicator, TabLayout and PagerSlidingTabStrip.

是我公众号的原创文章。我正在为当事人筹款，但我没有影响力，所以倍感艰难，希望大家多多支持。数以十万计的 App 从我的代码受益，希望大家也能帮帮我。

# Usage
Simple steps, you can integrate **MagicIndicator**:
1. checkout out **MagicIndicator**, which contains source code and demo
2. import module **magicindicator** and add dependency:
```groovy
implementation project(':magicindicator')
```
**or**
```groovy
repositories {
...
maven {
url "https://jitpack.io"
}
}
dependencies {
...
implementation 'com.github.hackware1993:MagicIndicator:1.6.0' // for support lib
implementation 'com.github.hackware1993:MagicIndicator:1.7.0' // for androidx
}
```
3. add **MagicIndicator** to your layout xml:
```xml
```
4. find **MagicIndicator** through code, initialize it:
```java
MagicIndicator magicIndicator = (MagicIndicator) findViewById(R.id.magic_indicator);
CommonNavigator commonNavigator = new CommonNavigator(this);
commonNavigator.setAdapter(new CommonNavigatorAdapter() {
@Override
public int getCount() {
return mTitleDataList == null ? 0 : mTitleDataList.size();
}
@Override
public IPagerTitleView getTitleView(Context context, final int index) {
ColorTransitionPagerTitleView colorTransitionPagerTitleView = new ColorTransitionPagerTitleView(context);
colorTransitionPagerTitleView.setNormalColor(Color.GRAY);
colorTransitionPagerTitleView.setSelectedColor(Color.BLACK);
colorTransitionPagerTitleView.setText(mTitleDataList.get(index));
colorTransitionPagerTitleView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
mViewPager.setCurrentItem(index);
}
});
return colorTransitionPagerTitleView;
}
@Override
public IPagerIndicator getIndicator(Context context) {
LinePagerIndicator indicator = new LinePagerIndicator(context);
indicator.setMode(LinePagerIndicator.MODE_WRAP_CONTENT);
return indicator;
}
});
magicIndicator.setNavigator(commonNavigator);
```
5. work with ViewPager:
```java
ViewPagerHelper.bind(magicIndicator, mViewPager);
```
**or**
work with Fragment Container(switch Fragment by hide()、show()):
```java
mFramentContainerHelper = new FragmentContainerHelper(magicIndicator);
// ...
mFragmentContainerHelper.handlePageSelected(pageIndex); // invoke when switch Fragment
```
# Extend
**MagicIndicator** can be easily extended:
1. implement **IPagerTitleView** to customize tab:
```java
public class MyPagerTitleView extends View implements IPagerTitleView {
public MyPagerTitleView(Context context) {
super(context);
}
@Override
public void onLeave(int index, int totalCount, float leavePercent, boolean leftToRight) {
}
@Override
public void onEnter(int index, int totalCount, float enterPercent, boolean leftToRight) {
}
@Override
public void onSelected(int index, int totalCount) {
}
@Override
public void onDeselected(int index, int totalCount) {
}
}
```
2. implement **IPagerIndicator** to customize indicator:
```java
public class MyPagerIndicator extends View implements IPagerIndicator {
public MyPagerIndicator(Context context) {
super(context);
}
@Override
public void onPageSelected(int position) {
}
@Override
public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {
}
@Override
public void onPageScrollStateChanged(int state) {
}
@Override
public void onPositionDataProvide(List dataList) {
}
}
```
3. use **CommonPagerTitleView** to load custom layout xml.
Now, enjoy yourself!
