Android Viewpager+Fragment实现滑动标签页

ViewPager 结合Fragment实现一个Activity里包含多个可滑动的标签页，每个标签页可以有独立的布局及响应。

主页布局

TaskDescribeFragment.java

package cn.com.ista.pdachina.ui;

import android.os.Bundle;
import android.support.annotation.Nullable;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;

public class TaskDescribeFragment extends Fragment {

    @Override
    public void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
    }

    @Override
    @Nullable
    public View onCreateView(LayoutInflater inflater,
            @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
        View rootView = inflater.inflate(R.layout.activity_taskdescribe_describe, container, false);//关联布局文件
        return rootView;
    }

    @Override
    public void onActivityCreated(@Nullable Bundle savedInstanceState) {
        super.onActivityCreated(savedInstanceState);
    }
}

其它三个Feagment与TaskDescribeFragment类似，不再贴代码
