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;

/**

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);
