之前看了别人的一些软件，发现其广告图轮询的时候，那个广告感觉和ViewPager的效果不太一样，后来也查了一下，是因为时间问题，找了一些资料，自己也实践一下。

1、为了解决ListView头部加ViewPager滑动冲突问题，必须自定义ListView，重写里面的onInterceptTouchEvent方法，ListView代码如下：

package com.example.testa;

import android.content.Context;
import android.util.AttributeSet;
import android.view.MotionEvent;
import android.widget.ListView;

public class DefinedListView extends ListView {

public DefinedListView(Context context) {
super(context);
}

public DefinedListView(Context context, AttributeSet attrs) {
super(context, attrs);
}

public DefinedListView(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
}

private float xDistance, yDistance, xLast, yLast;

@Override
public boolean onInterceptTouchEvent(MotionEvent ev) {
switch (ev.getAction()) {
case MotionEvent.ACTION_DOWN:
xDistance = yDistance = 0f;
xLast = ev.getX();
yLast = ev.getY();
break;
case MotionEvent.ACTION_MOVE:
final float curX = ev.getX();
final float curY = ev.getY();
xDistance += Math.abs(curX - xLast);
yDistance += Math.abs(curY - yLast);
xLast = curX;
yLast = curY;
if (xDistance > yDistance) {
return false;
}
}
return super.onInterceptTouchEvent(ev);
}
}

package com.example.testa;

import java.lang.reflect.Field;

import android.annotation.SuppressLint;
import android.content.Context;
import android.os.Handler;
import android.support.v4.app.FragmentActivity;
import android.support.v4.view.ViewPager;
import android.view.LayoutInflater;
import android.view.MotionEvent;
import android.view.View;
import android.view.View.OnTouchListener;
import android.view.animation.Interpolator;
import android.widget.Scroller;

public class DefinedScroller extends Scroller {

private int DURATION_TIME = 1000;

private boolean shouldAutoScroll = true;
private ViewPager viewPager = null;

@SuppressLint("HandlerLeak")
private final Handler handler = new Handler() {
public void handleMessage(android.os.Message msg) {
if (shouldAutoScroll) {
viewPager.setCurrentItem(viewPager.getCurrentItem() + 1);
handler.sendEmptyMessageDelayed(0, 2000);
}
};
};

public DefinedScroller(Context context) {
super(context);
}

public DefinedScroller(Context context, Interpolator interpolator) {
super(context, interpolator);
}

private View initViewPager(Context context) {
View view = LayoutInflater.from(context).inflate(R.layout.view_pager_layout, null);
this.viewPager = (ViewPager) view.findViewById(R.id.viewpager);
this.viewPager.setOffscreenPageLimit(2);
this.viewPager.setAdapter(new MyFragmentPagerAdapter(((FragmentActivity) context).getSupportFragmentManager()));
return view;
}

public ViewPager getViewPager() {
return viewPager;
}

public View initView(Context context) {
View view = initViewPager(context);
this.viewPager.setOnTouchListener(new OnTouchListener() {

@Override
public boolean onTouch(View v, MotionEvent event) {
if (event.getAction() == MotionEvent.ACTION_UP) {
shouldAutoScroll = true;
handler.sendEmptyMessageDelayed(0, 2000);
} else {
handler.removeMessages(0);
shouldAutoScroll = false;
}
return false;
}
});
try {
Field mScroller = ViewPager.class.getDeclaredField("mScroller");
mScroller.setAccessible(true);
mScroller.set(viewPager, this);
} catch (NoSuchFieldException e) {

} catch (IllegalArgumentException e) {

} catch (IllegalAccessException e) {

}
handler.sendEmptyMessageDelayed(0, 2000);
return view;
}

public void setShouldAutoScroll() {
handler.removeMessages(0);
if (viewPager.isShown()) {
shouldAutoScroll = true;
handler.sendEmptyMessageDelayed(0, 2000);
} else {
shouldAutoScroll = false;
}
}

@Override
public void startScroll(int startX, int startY, int dx, int dy, int duration) {
super.startScroll(startX, startY, dx, dy, shouldAutoScroll ? DURATION_TIME : duration);
}

}

3、其他测试类，

（1）TestFragment：

package com.example.testa;

import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ImageView;

public class TestFragment extends Fragment {

public int imageResource = 0;

public static TestFragment newInstance(int imageResource) {
TestFragment newFragment = new TestFragment();
newFragment.imageResource = imageResource;
return newFragment;

}

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.pager_layout, null);
ImageView textView = (ImageView) view.findViewById(R.id.image);
textView.setImageResource(imageResource);
return view;
}

}

package com.example.testa;

import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentStatePagerAdapter;

public class MyFragmentPagerAdapter extends FragmentStatePagerAdapter {

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

@Override
public int getCount() {
return Integer.MAX_VALUE;
}

@Override
public Fragment getItem(int arg0) {
switch (arg0 % 4) {
case 0:
return TestFragment.newInstance(R.drawable.a1);
case 1:
return TestFragment.newInstance(R.drawable.default_wh);
case 2:
return TestFragment.newInstance(R.drawable.default_ww);
case 3:
return TestFragment.newInstance(R.drawable.test);
default:
return TestFragment.newInstance(R.drawable.a1);
}
}

}

package com.example.testa;

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

import android.os.Bundle;
import android.support.v4.app.FragmentActivity;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.AbsListView;
import android.widget.AbsListView.OnScrollListener;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.BaseAdapter;
import android.widget.TextView;

public class MainActivity extends FragmentActivity {

private DefinedListView listView = null;
private List<String> list = null;

private DefinedScroller definedScroller = null;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
listView = (DefinedListView) findViewById(R.id.listview);
initListData();
initViewPager();
listView.setAdapter(new ListAdapter());
listView.setOnItemClickListener(new OnItemClickListener() {

@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
definedScroller.getViewPager().setCurrentItem(definedScroller.getViewPager().getCurrentItem() + 1);
}
});

listView.setOnScrollListener(new OnScrollListener() {

@Override
public void onScrollStateChanged(AbsListView view, int scrollState) {
if (scrollState == SCROLL_STATE_IDLE) {
definedScroller.setShouldAutoScroll();
}
}

@Override
public void onScroll(AbsListView view, int firstVisibleItem, int visibleItemCount, int totalItemCount) {

}
});
}

private void initListData() {
list = new ArrayList<String>();
for (int i = 1; i <= 20; ++i) {
list.add("test" + i);
}
}

private void initViewPager() {
definedScroller = new DefinedScroller(this);
listView.addHeaderView(definedScroller.initView(this));
}

private class ListAdapter extends BaseAdapter {

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

@Override
public Object getItem(int position) {
return list.get(position);
}

@Override
public long getItemId(int position) {
return position;
}

@Override
public View getView(int position, View convertView, ViewGroup parent) {
TextView textView = (TextView) LayoutInflater.from(MainActivity.this).inflate(R.layout.text_view_layout,
null);
textView.setPadding(20, 20, 20, 20);
textView.setText(list.get(position));
return textView;
}

}

}
