Android实现翻页特效

android-flip 是一个能够轻松帮你实现水平以及竖直翻页特效的库，但是在判断翻页的时候有bug，我们需要在FlipCards.java中找到这一段：

if (Math.abs(getPageIndexFromAngle(accumulatedAngle + angleDelta) - lastPageIndex) <= 1) {accumulatedAngle += angleDelta;}

[/code]

将它更改为：

if(((accumulatedAngle + angleDelta > lastPageIndex*180)&& (accumulatedAngle + angleDelta <= (lastPageIndex+1) * 180)) ||((accumulatedAngle + angleDelta < lastPageIndex*180) &&(accumulatedAngle + angleDelta >= (lastPageIndex-1) * 180))){accumulatedAngle += angleDelta;}

[/code]
而在翻页的时候会有闪烁现象产生，为了减轻现象的发生，我们需要修改另外一个地方，在FlipViewController.java中找到这一段：

void postHideFlipAnimation() {if (inFlipAnimation) {handler.post(new Runnable() {@Overridepublic void run() {hideFlipAnimation();}});}}

[/code]
修改为：

void postHideFlipAnimation() {if (inFlipAnimation) {handler.postDelayed(new Runnable() {@Overridepublic void run() {hideFlipAnimation();}}, 200);}}

[/code]
然后我们就可以轻松地用它来为我们的app添加翻页特效，在Activity中添加代码：

package com.nekocode.xuedao;import android.os.Bundle;import com.actionbarsherlock.app.SherlockFragmentActivity;import com.aphidmobile.flip.FlipViewController;import com.nekocode.xuedao.adapter.SubscribeIndexAdapter;public class SubsecribeIndexActivity extends SherlockFragmentActivity {private PublicData pd;private FlipViewController mFlipView;@Overridepublic void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);pd = PublicData.getInstance();mFlipView = new FlipViewController(this, FlipViewController.HORIZONTAL);mFlipView.setAdapter(new SubscribeIndexAdapter(this));setContentView(mFlipView);}@Overrideprotected void onResume() {super.onResume();mFlipView.onResume();}@Overrideprotected void onPause() {super.onPause();mFlipView.onPause();}}

[/code]
创建FlipAdapter：

package com.nekocode.xuedao.adapter;import android.content.Context;import android.view.LayoutInflater;import android.view.View;import android.view.ViewGroup;import android.widget.BaseAdapter;import android.widget.TextView;import com.aphidmobile.utils.UI;import com.nekocode.xuedao.R;public class SubscribeIndexAdapter extends BaseAdapter {private LayoutInflater inflater;public SubscribeIndexAdapter(Context context) {inflater = LayoutInflater.from(context);}@Overridepublic int getCount() {return 5;}@Overridepublic Object getItem(int position) {return position;}@Overridepublic long getItemId(int position) {return position;}@Overridepublic View getView(int position, View convertView, ViewGroup parent) {View layout = convertView;if (convertView == null) {layout = inflater.inflate(R.layout.item_subscribe_index, null);}UI.<TextView>findViewById(layout, R.id.textView7).setText(\"今日热点\" + position);return layout;}}

[/code]
layout文件并没有什么重要信息所以不放出代码了，效果图：
