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;
}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;
}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() {
@Override
public void run() {
hideFlipAnimation();
}
});
}
}修改为：
void postHideFlipAnimation() {
if (inFlipAnimation) {
handler.postDelayed(new Runnable() {
@Override
public void run() {
hideFlipAnimation();
}
}, 200);
}
}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;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
pd = PublicData.getInstance();
mFlipView = new FlipViewController(this, FlipViewController.HORIZONTAL);
mFlipView.setAdapter(new SubscribeIndexAdapter(this));
setContentView(mFlipView);
}
@Override
protected void onResume() {
super.onResume();
mFlipView.onResume();
}
@Override
protected void onPause() {
super.onPause();
mFlipView.onPause();
}
}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);
}
@Override
public int getCount() {
return 5;
}
@Override
public Object getItem(int position) {
return position;
}
@Override
public long getItemId(int position) {
return position;
}
@Override
public 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;
}
}layout文件并没有什么重要信息所以不放出代码了，效果图：
