AbSlidingPlayView是AndBase框架中的功能之一，今天就来尝试用AbSlidingPlayView来做一个好多类新闻app都会涉及到的，广播轮播效果，能和viewpager一样实现滑动，并且带有各种监听事件
下面先贴出AbSlidingPlayView类的源码，基本只要复制黏贴到项目中去即可

}代码很长，里面有各种注释，就不多说了，可以仔细研究一下里面的源码，可以对轮播效果进行各种控制，比如翻页的快慢，翻页的时长等等
在这里还需要用到一些其他的接口类，这里就不贴出来了，后面会贴出demo的下载地址，
接下来我们写一个布局文件，很简单，直接上代码
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<com.example.utils.AbSlidingPlayView
android:id="@+id/mAbSlidingPlayView"
android:layout_width="match_parent"
android:layout_height="150dp">
</com.example.utils.AbSlidingPlayView>
</RelativeLayout>
就只有一个自定义的控件。
接下来上主Activity的代码：
import java.util.ArrayList;
import com.example.utils.AbOnChangeListener;
import com.example.utils.AbOnItemClickListener;
import com.example.utils.AbSlidingPlayView;
import android.app.Activity;
import android.content.Context;
import android.os.Bundle;
import android.view.Gravity;
import android.view.LayoutInflater;
import android.view.View;
import android.widget.ImageView;
public class TextActivity extends Activity{
private AbSlidingPlayView mSlidingPlayView;
private Context mContext;
private ArrayList<Integer> list;
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.textac);
mContext=this;
list=new ArrayList<Integer>();
//先来一个测试的arrayList，给他添加一些图片进去
list.add(R.drawable.girl);
list.add(R.drawable.shibai);
list.add(R.drawable.shibai);
mSlidingPlayView=(AbSlidingPlayView) findViewById(R.id.mAbSlidingPlayView);
mSlidingPlayView.setPageLineHorizontalGravity(Gravity.RIGHT);
//mSlidingPlayView的点击事件
mSlidingPlayView.setOnItemClickListener(new AbOnItemClickListener() {
@Override
public void onClick(int position) {
mSlidingPlayView.setOverScrollMode(View.OVER_SCROLL_ALWAYS);
mSlidingPlayView.clearChildFocus(mSlidingPlayView.getFocusedChild());
}
});
//mSlidingPlayView的滑动的监听事件
mSlidingPlayView.setOnPageChangeListener(new AbOnChangeListener() {
@Override
public void onChange(int position) {
}
});
//对list进行循环
for(int i=0;i<list.size();i++){
final View playView = LayoutInflater.from(mContext).inflate(R.layout.play_view_item, null);
ImageView playImage =
(ImageView) playView.findViewById(R.id.mPlayImage);
playImage.setImageResource(list.get(i));
//最后把playView添加到mSlidingPlayView里面去
mSlidingPlayView.addView(playView);
}
}
@Override
protected void onResume() {
// TODO Auto-generated method stub
super.onResume();
//mSlidingPlayView开始循环播放
mSlidingPlayView.startPlay();
}
@Override
protected void onStop() {
// TODO Auto-generated method stub
super.onStop();
//mSlidingPlayView结束循环播放
mSlidingPlayView.stopPlay();
}
}
里面有各种接口和监听事件，是不是很简单！
