MainActivity类

package com.klxair.slidingupdown;

import com.klxair.slidingupdown.view.DragLayout;
import com.klxair.slidingupdown.view.DragLayout.ShowNextPageNotifier;

import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.view.Menu;
import android.view.MenuItem;
import android.view.Window;

public class MainActivity extends AppCompatActivity {

    private Fragment1 fragment1;
    private Fragment2 fragment2;
    private DragLayout draglayout;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        setContentView(R.layout.activity_main);
        initView();
    }

    /**
     * 初始化View
     */
    private void initView() {
        fragment1 = new Fragment1();
        fragment2 = new Fragment2();

        getSupportFragmentManager().beginTransaction().add(R.id.first, fragment1).add(R.id.second, fragment2).commit();

        ShowNextPageNotifier nextIntf = new ShowNextPageNotifier() {
            @Override
            public void onDragNext() {
                fragment2.initView();
            }
        };
        draglayout = (DragLayout) findViewById(R.id.draglayout);
        draglayout.setNextPageListener(nextIntf);
    }

}

Fragment1

布局文件可自己随意编写，这里就不贴出了

package com.klxair.slidingupdown;

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

public class Fragment1 extends Fragment {

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        View rootView = inflater.inflate(R.layout.fragment1, null);
        return rootView;
    }
}

Fragment2

package com.klxair.slidingupdown;

import com.klxair.slidingupdown.view.CustWebView;

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

public class Fragment2 extends Fragment {

    private View progressBar;
    private CustWebView webview;
    private boolean hasInited = false;

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        View rootView = inflater.inflate(R.layout.fragment2, null);
        webview = (CustWebView) rootView.findViewById(R.id.fragment3_webview);
        progressBar = rootView.findViewById(R.id.progressbar);
        return rootView;
    }

    public void initView() {
        if (null != webview && !hasInited) {
            hasInited = true;
            progressBar.setVisibility(View.GONE);
            webview.loadUrl("https://www.baidu.com/");
        }
    }
}
