app引导功能界面+广告轮播控件，两句代码搞定

广告轮播控件

MainActivity.java

import android.content.Intent;
import android.graphics.Color;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.ImageView;
import android.widget.Toast;

import com.orandnot.rtviewpager.PageIndicatorView;
import com.orandnot.rtviewpager.RecycleTimePageAdptar;
import com.orandnot.rtviewpager.RecycleTimeViewPage;
import com.orandnot.rtviewpager.animation.AnimationType;

import java.util.ArrayList;
import java.util.List;

public class MainActivity extends AppCompatActivity implements RecycleTimePageAdptar.OnPageClickListener{

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
init();
initWeclome();
}

private void initWeclome() {
findViewById(R.id.button).setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
startActivity(new Intent(MainActivity.this,WelcomeActivity.class));
}
});
}

private void init() {
RecycleTimeViewPage rtPageView = (RecycleTimeViewPage) findViewById(R.id.rtPageView);
List list = new ArrayList<>();
int[] imgId = new int[]{R.mipmap.img_0, R.mipmap.img_1, R.mipmap.img_2, R.mipmap.img_3};
for (int id : imgId) {
ImageView view = new ImageView(this);
view.setScaleType(ImageView.ScaleType.CENTER_CROP);
view.setImageResource(id);
list.add(view);
}
RecycleTimePageAdptar mAdpter = new RecycleTimePageAdptar(this,list);
mAdpter.setListener(this);
rtPageView.setAdapter(mAdpter);
rtPageView.setIntervalTime(3).startAutoPlay();

PageIndicatorView indicatorView = (PageIndicatorView) findViewById(R.id.pageIndicatorView);
indicatorView.setRadius(3)
.setPadding(5)
.setAnimationType(AnimationType.THIN_WORM)
.setInteractiveAnimation(true)
.setSelectedColor(Color.GREEN)
.setUnselectedColor(Color.WHITE)
.setViewPager(rtPageView);

}

@Override
public void onPagePosition(int position) {
Toast.makeText(this,">>>click>>>position="+position,Toast.LENGTH_SHORT).show();
}
}

基本就实现了大部分app的广告轮播的需求了，主要步骤就是，给RecycleTimeViewPage填充数据，rtPageView.setIntervalTime(3).startAutoPlay()设置时间，自动轮播就可以了。这里需要导入包rtviewpager.jar,这个包是我自己写的，结合了开源项目PageIndicatorView就是底部的指引控件(具体的使用方法自己可以去找)。

引导功能界面

第一次安装app往往需要引导界面，实现方式很多种，一般都是ViewPager来实现，除了加载动画效果和做点视差动画，没什么特别的。和上面定时轮播区别就是把界面设成全屏，然后去掉定时器。还有就是viewpager里的view要自定义一下。

有个内存泄露的问题。。。有空解决
