实现编码：

LinearLayout布局：

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:orientation="vertical" android:layout_width="match_parent"    android:layout_height="match_parent">    <LinearLayout        android:layout_width="match_parent"        android:layout_height="match_parent"        android:orientation="vertical"        android:gravity="center">        <TextView            android:layout_width="wrap_content"            android:layout_height="wrap_content"            android:text="this"/>        <TextView            android:layout_width="wrap_content"            android:layout_height="wrap_content"            android:text="is"/>        <TextView            android:layout_width="wrap_content"            android:layout_height="wrap_content"            android:text="LinearLayout"/>    </LinearLayout></LinearLayout>

RelativeLayout

<?xml version="1.0" encoding="utf-8"?><RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="match_parent"     android:layout_height="match_parent"    android:gravity="center">    <RelativeLayout        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:gravity="center">        <TextView            android:layout_width="100dp"            android:layout_height="100dp"            android:background="#ff0000"            android:id="@+id/tv_relativelayout"/>        <TextView            android:layout_width="80dp"            android:layout_height="80dp"            android:background="#00ff00"            android:layout_toRightOf="@+id/tv_relativelayout"/>    </RelativeLayout></RelativeLayout>

FrameLayout帧布局：

<?xml version="1.0" encoding="utf-8"?><FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="match_parent" android:layout_height="match_parent"    >    <FrameLayout        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:layout_gravity="center">        <TextView            android:layout_width="100dp"            android:layout_height="100dp"            android:background="#ff0000"            android:id="@+id/tv_framelayout"            />        <TextView            android:layout_width="80dp"            android:layout_height="80dp"            android:background="#00ff00"            android:layout_gravity="center"/>            </FrameLayout></FrameLayout>

Activity文件：

package com.zking.admin.android_12;import android.support.v4.view.PagerAdapter;import android.support.v4.view.ViewPager;import android.support.v7.app.AppCompatActivity;import android.os.Bundle;import android.view.View;import android.view.ViewGroup;import android.widget.Toast;import java.util.ArrayList;import java.util.List;public class ZuoyeViewpagerActivity extends AppCompatActivity {    private ViewPager vp_zuoye_viewpager;    private List<View> views=new ArrayList<>();    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_zuoye_viewpager);        vp_zuoye_viewpager = (ViewPager) findViewById(R.id.vp_zuoye_viewpager);        //将布局转化成View，加入View集合中        views.add(getLayoutInflater().inflate(R.layout.activity_zuoye_framelayout,null));        views.add(getLayoutInflater().inflate(R.layout.activity_zuoye_linearlayout,null));        views.add(getLayoutInflater().inflate(R.layout.activity_zuoye_relativelayout,null));        vp_zuoye_viewpager.setAdapter(new Myadapter());    }    class Myadapter extends PagerAdapter{        //有多少个View显示        @Override        public int getCount() {            return views.size();        }        //是否是View控件        @Override        public boolean isViewFromObject(View view, Object object) {            return view==object;        }        @Override        public Object instantiateItem(ViewGroup container, int position) {            View v=views.get(position);            //            container.addView(v);            return v;        }        @Override        public void destroyItem(ViewGroup container, int position, Object object) {            View v=views.get(position);            container.removeView(v);        }    }}
