自定义circleindicator

在此申明，并不是自己写的，只是为了方便日后使用

我使用的circleindicator是从大神的gitHub中弄来的，

使用如下：

一、在配置中导入

compile 'me.relex:circleindicator:1.2.2@aar'

二、就可以直接使用了

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".GuideActivity">

  <android.support.v4.view.ViewPager
      android:id="@+id/viewpager"
      android:layout_width="match_parent"
      android:layout_height="match_parent">
  </android.support.v4.view.ViewPager>
    <me.relex.circleindicator.CircleIndicator
        android:id="@+id/indicator"
        android:layout_alignParentBottom="true"
        android:layout_width="match_parent"
        android:layout_height="48dp"/>
</RelativeLayout>

三、就是设置数据等等了

 package com.wangy.myquestionnairesurvey.surveyActivity.MyDream;

 import android.os.Bundle;
 import android.support.v4.app.Fragment;
 import android.support.v4.app.FragmentActivity;
 import android.support.v4.app.FragmentManager;
 import android.support.v4.app.FragmentPagerAdapter;
 import android.support.v4.view.ViewPager;
 import android.support.v7.app.AppCompatActivity;

 import com.wangy.myquestionnairesurvey.R;

 import java.util.ArrayList;

 import me.relex.circleindicator.CircleIndicator;

 /**
  * Created by xhb on 2016/12/19.
  */
 public class DreamServeyActivity extends FragmentActivity {

     private ViewPager viewPager;
     private CircleIndicator indicator;
     private ArrayList<Fragment> fragmentList;
     private FragmentlistAdapter fragmentlistAdapter;

     @Override
     protected void onCreate(Bundle savedInstanceState) {
         super.onCreate(savedInstanceState);
         setContentView(R.layout.dreamsurvey);
         initview();
     }

     private void initview() {
         viewPager = (ViewPager) findViewById(R.id.viewpager);
         indicator = (CircleIndicator) findViewById(R.id.indicator);
         Fragment fragment1 = new DreamSyrvey1Activity();
         Fragment fragment2 = new DreamSyrvey2Activity();
         Fragment fragment3 = new DreamSyrvey3Activity();
         fragmentList = new ArrayList<>();
         fragmentList.add(fragment1);
         fragmentList.add(fragment2);
         fragmentList.add(fragment3);
         initData();
     }

     private void initData() {
         fragmentlistAdapter = new FragmentlistAdapter(getSupportFragmentManager());
         viewPager.setAdapter(fragmentlistAdapter);
         indicator.setViewPager(viewPager);
     }

     class FragmentlistAdapter extends FragmentPagerAdapter {

         public FragmentlistAdapter(FragmentManager fm) {
             super(fm);
         }

         @Override
         public Fragment getItem(int position) {
             return fragmentList.get(position);
         }

         @Override
         public int getCount() {
             return fragmentList.size();
         }
     }
 }

ok，可以直接使用了，circleindicator，好像这个默认圆是白色的，好像可以改它的样式

 //修改样式
 indicator.configureIndicator(10,10,5, me.relex.circleindicator.R.animator.scale_with_alpha
         , 0, me.relex.circleindicator.R.drawable.white_radius//图片
         , me.relex.circleindicator.R.drawable.white_radius);
