ViewPager的定時(shí)滾動(dòng)，動(dòng)態(tài)加載數(shù)據(jù)

viewpager是用在滾動(dòng)中相對(duì)比較多的走孽，最近做一個(gè)定時(shí)滾動(dòng)顯示viewpager內(nèi)容念逞。

步驟：

一：在布局文件添加v4包下的viewpager：

android:id="@+id/main_viewpager"

android:layout_width="match_parent"

android:layout_height="match_parent"

android:layout_gravity="center">

二：獲取后臺(tái)數(shù)據(jù)，現(xiàn)在就暫時(shí)自己造幾條數(shù)據(jù)创淡，并寫adapter內(nèi)容

//構(gòu)造list集合

list=newArrayList();

list.add(R.mipmap.image1);

list.add(R.mipmap.image2);

list.add(R.mipmap.image3);

//我這邊是顯示的viewpager的很多信息，包括圖片文字劳较，所以構(gòu)造view墓捻，在Java中寫布局代碼凸丸，

這個(gè)時(shí)候就需要我們構(gòu)造view环肘，privateListmList=new ArryList;

循化list集合數(shù)據(jù)腌零，創(chuàng)建頁(yè)面詳情，通過(guò)add方法加載到mList记舆，這樣adapter中就可以傳遞過(guò)去值了：

for(inti =0;i

rootlayout=newRelativeLayout(this);

rootlayout.setLayoutParams(newRelativeLayout.LayoutParams(

RelativeLayout.LayoutParams.MATCH_PARENT,RelativeLayout.LayoutParams.MATCH_PARENT));

rootlayout.setId(0);

來(lái)講講adapter，基本寫法就行坑傅，但是注意的是在添加view的時(shí)候必須保證是一個(gè)view的parent喷斋，要不然報(bào)錯(cuò)：

public classTTMyPagerAdaptersextendsPagerAdapter {

publicListlistViews=null;

publicTTestViewPagersActivitymContext;

publicTTMyPagerAdapters(List listViews,TTestViewPagersActivity mContext) {

this.listViews= listViews;

this.mContext= mContext;

Share.d("listviews"+ listViews.size());

}

@Override

public intgetCount() {

returnInteger.MAX_VALUE;

}

@Override

public booleanisViewFromObject(View arg0,Object arg1) {

returnarg0 == arg1;

}

@Override

public voiddestroyItem(View container, intposition,Object object) {

Share.d("TipsPagerAdapter,destroyItem is called? "+ position);

((ViewPager) container).removeView(listViews.get(position %listViews.size()));

}

@Override

publicCharSequencegetPageTitle(intposition) {

return super.getPageTitle(position);

}

@Override

publicObjectinstantiateItem(View container, intposition) {

Share.d("TipsPagerAdapter, instantiateItem is called "+ position);

try{

((ViewPager) container).addView(

listViews.get(position %listViews.size()),0);

}catch(Exception e) {

}

// ((ViewPager) container).addView(listViews.get(position);

// return listViews.get(position);

Share.d("instantiateItem>>>>>>"+ position %listViews.size());

returnlistViews.get(position %listViews.size());

}

}

好了現(xiàn)在就是直接setadapter就行了枉证，然后寫個(gè)線程循環(huán)跳

adapter=newTTMyPagerAdapters(mList, this);

mPager.setAdapter(adapter);

mPager.setCurrentItem(position);

position是初始滑動(dòng)值，凈量設(shè)置越大越好毡鉴，一般滑不到頭

private voidinitAdapter() {

Share.d("mlist"+mList.size());

//

//TODO Auto-generated method stub

//TODO Auto-generated catch block

change=newThread(newRunnable() {

@Override

public voidrun() {

//TODO Auto-generated method stub

while(true) {

handler.sendEmptyMessage(0);

try{

Thread.sleep(5000);

}catch(InterruptedException e) {

//TODO Auto-generated catch block

e.printStackTrace();

}

}

}

});

change.start();

}

@SuppressLint("HandlerLeak")

privateHandlerhandler=newHandler() {

@Override

public voidhandleMessage(Message msg) {

super.handleMessage(msg);

switch(msg.what) {

case0:

position++;

mPager.setCurrentItem(position);

break;

}

}

};

好了現(xiàn)在可沒有結(jié)束猪瞬，你會(huì)發(fā)現(xiàn)list的集合數(shù)小于3的時(shí)候又空白頁(yè)出現(xiàn)陈瘦，但是一張的時(shí)候你又不想讓他滾動(dòng)潮售，怎么辦酥诽？主要是數(shù)據(jù)太短銷毀的時(shí)候有bug肮帐，要是list多了那就無(wú)所謂了，所以怎么辦呢托修？其中一個(gè)辦法睦刃，可以把小于3的list通過(guò)一個(gè)for循環(huán)構(gòu)造出大于他不就OK了仗处，所以那就開干婆誓，循環(huán)添加吧也颤！總結(jié)這個(gè)問(wèn)題就是數(shù)據(jù)一條的時(shí)候翅娶，和2/3條的時(shí)候和多于3條的時(shí)候情況不一樣好唯，分別處理骑篙，我的做法是先在判斷集合以2為界限判斷森书，實(shí)驗(yàn)多次就是2的時(shí)候容易空白凛膏，所以區(qū)分是2和不是的時(shí)候猖毫，是2的話讓他for循環(huán)添加兩次進(jìn)去數(shù)據(jù)變成4就好了，不是2的正常執(zhí)行趁蕊，但是不是2的里邊包括1個(gè)的時(shí)候介衔，那么就在setadapter的時(shí)候處理，區(qū)分新的list是1還是大于3的骂因，這樣問(wèn)題就解決了炎咖，下邊附上全部代碼！
