pager和fragment绑定使用的完整代码。

pager和fragment绑定使用的完整代码。

Fragment的代码，没什么特别就只是一个界面而已。
但是这里要实现的方法和activity有点不同是实现OnCreateView(activity是实现OnCreate)

package com.zsz.develop.wisdomcommunity.main;

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;

import com.zsz.develop.wisdomcommunity.R;

/**
 * Created by shengzhong on 2015/8/28.
 */
public class FragmentDoor extends Fragment {

@Nullable
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

    View view=inflater.inflate(R.layout.door_view_pager,null);
    return view;

}
}

pager页面

• 1.定义好两个list一个装view、一个装fragment
• 2.对于pager这种需要后期添加的都需要对他设置adapter
• 3.pager是针对fragment设置的adapter所以他就要使用fragment的适配器。中间要加个管理器。

package com.zsz.develop.wisdomcommunity.main;

import android.app.FragmentManager;
import android.app.FragmentTransaction;
import android.content.Intent;
import android.support.v4.app.Fragment;

import java.util.ArrayList;
import java.util.List;

public class MainViewPagerActivity extends AppCompatActivity implements View.OnClickListener {

private ViewPager pager = null;
private List<Fragment> fragmentlist=new ArrayList<>();
ArrayList<View> viewContainter = new ArrayList<View>();

private LinearLayout llCloud,llDoor,llMy;
private View myView;
public String TAG = "tag";

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main_view_pager);



    pager= (ViewPager) findViewById(R.id.viewPager);

    llCloud= (LinearLayout) findViewById(R.id.llCloud);
    llDoor= (LinearLayout) findViewById(R.id.llDoor);
    llMy= (LinearLayout) findViewById(R.id.llMy);

    llMy.setOnClickListener(this);
    llDoor.setOnClickListener(this);
    llCloud.setOnClickListener(this);

    fragmentlist.add(new FragmentCloud());
    fragmentlist.add(new FragmentDoor());
    fragmentlist.add(new FragmentMy());

    myView= LayoutInflater.from(this).inflate(R.layout.my_view_pager,null);
    View doorView= LayoutInflater.from(this).inflate(R.layout.door_view_pager,null);
    View cloudView= LayoutInflater.from(this).inflate(R.layout.cloud_view_pager,null);

    viewContainter.add(cloudView);
    viewContainter.add(doorView);
    viewContainter.add(myView);





    pager.setAdapter(new FragmentPagerAdapter(getSupportFragmentManager()) {


        @Override
        public int getCount() {
            return fragmentlist.size();
        }

        @Override
        public Fragment getItem(int position) {
            return fragmentlist.get(position);
        }
    });


    pager.setCurrentItem(1);
    pager.addOnPageChangeListener(new ViewPager.OnPageChangeListener() {
        @Override
        public void onPageScrollStateChanged(int arg0) {
            Log.d(TAG, "--------changed:" + arg0);
        }

        @Override
        public void onPageScrolled(int arg0, float arg1, int arg2) {
            Log.d(TAG, "-------scrolled arg0:" + arg0);
            Log.d(TAG, "-------scrolled arg1:" + arg1);
            Log.d(TAG, "-------scrolled arg2:" + arg2);
        }

        //选择的位置
        @Override
        public void onPageSelected(int position) {
            Log.d(TAG, "------selected:" + position);
        }
    });



}




@Override
public void onClick(View view) {
    int id=view.getId();
    switch (id){
        case R.id.llCloud:
            pager.setCurrentItem(0);
            break;
        case R.id.llDoor:
            pager.setCurrentItem(1);
            break;
        case R.id.llMy:
            pager.setCurrentItem(2);
            break;

   }

}

}

对于viewpager的layout

<android.support.v4.view.ViewPager
    android:id="@+id/viewPager"
    android:layout_width="wrap_content"
    android:layout_height="0dp"
    android:layout_weight="1"
    >

</android.support.v4.view.ViewPager>

最简单的pager和fragment的结合使用

package com.zsz.develop.exercisedemo;

import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentPagerAdapter;
import android.support.v4.view.ViewPager;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;

import java.util.ArrayList;

public class ViewPagerActivity extends AppCompatActivity {

private ViewPager viewPager;
private ArrayList<Fragment> fragmentArrayList=new ArrayList<>();
private ArrayList<View> viewArrayList=new ArrayList<>();



@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_view_pager);
    viewPager= (ViewPager) findViewById(R.id.vp);
    fragmentArrayList.add(new MyFragment());
    fragmentArrayList.add(new MyFragment02());
    fragmentArrayList.add(new MyFragment());

// viewArrayList.add()
viewPager.setAdapter(new FragmentPagerAdapter(getSupportFragmentManager()) {
@Override
public Fragment getItem(int i) {
return fragmentArrayList.get(i);
}

        @Override
        public int getCount() {
            return fragmentArrayList.size();
        }
    });

}

}
