我正在學習如何實現水平掃動，並且在嘗試啓動我的在其佈局中具有ViewPager的應用程序時出現以下錯誤。

我嘗試了這個鏈接的解決方案，但它並沒有爲我工作。 Error inflating class android.support.v4.view.ViewPager

activity_main.xml中

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
xmlns:tools="http://schemas.android.com/tools" 
android:layout_width="match_parent" 
android:layout_height="match_parent" 
android:paddingBottom="@dimen/activity_vertical_margin" 
android:paddingLeft="@dimen/activity_horizontal_margin" 
android:paddingRight="@dimen/activity_horizontal_margin" 
android:paddingTop="@dimen/activity_vertical_margin" 
tools:context=".MainActivity" > 

<android.support.v4.app.ViewPager 
    android:id="@+id/pager" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    /> 

</RelativeLayout> 

碎片的佈局文件包含一個簡單TextView。片段類如下：

public class MyFragment extends Fragment{ 
int mCurrentPage; 

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

    /** Getting the arguments to the Bundle object */ 
    Bundle data = getArguments(); 

    /** Getting integer data of the key current_page from the bundle */ 
    mCurrentPage = data.getInt("current_page", 0); 

} 

@Override 
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { 
    View v = inflater.inflate(R.layout.frag_layout, container,false); 
    TextView tv = (TextView) v.findViewById(R.id.tv); 
    tv.setText("You are viewing the page #" + mCurrentPage + "\n\n" + "Swipe Horizontally left/right"); 
    return v; 
} 
} 

的FragmentPagerAdapter類：

public class MyAdapter extends FragmentPagerAdapter{ 

final int PAGE_COUNT = 3; 
public MyAdapter(FragmentManager fm) { 
    super(fm); 
    // TODO Auto-generated constructor stub 
} 

@Override 
public Fragment getItem(int arg0) { 
    // TODO Auto-generated method stub 
    MyFragment myFragment = new MyFragment(); 
    Bundle data = new Bundle(); 
    data.putInt("current_page", arg0+1); 
    myFragment.setArguments(data); 
    return myFragment; 
} 

@Override 
public int getCount() { 
    // TODO Auto-generated method stub 
    return PAGE_COUNT; 
} 
} 

主要活動：

public class MainActivity extends FragmentActivity { 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 
    ViewPager pager = (ViewPager) findViewById(R.id.pager); 

    /** Instantiating FragmentPagerAdapter */ 
    MyAdapter pagerAdapter = new MyAdapter(getSupportFragmentManager()); 

    /** Setting the pagerAdapter to the pager object */ 
    pager.setAdapter(pagerAdapter); 
} 

@Override 
public boolean onCreateOptionsMenu(Menu menu) { 
    // Inflate the menu; this adds items to the action bar if it is present. 
    getMenuInflater().inflate(R.menu.main, menu); 
    return true; 
} 

}

嗨，我剛纔做了一些變化，你的佈局文件&其工作現在好..

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:tools="http://schemas.android.com/tools" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:padding="10dp" > 

    <android.support.v4.view.ViewPager 
     android:id="@+id/pager" 
     android:layout_width="fill_parent" 
     android:layout_height="fill_parent" /> 

</RelativeLayout> 

你可以檢查此：

下面的代碼是隻爲你refrance ---->

您的主要活動：

package com.example.viewpage; 

import android.app.Activity; 
import android.os.Bundle; 
import android.support.v4.app.FragmentActivity; 
import android.support.v4.view.ViewPager; 
import android.view.Menu; 

public class MainActivity extends FragmentActivity { 

    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 

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

     /** Instantiating FragmentPagerAdapter */ 
     MyAdapter pagerAdapter = new MyAdapter(getSupportFragmentManager()); 

     /** Setting the pagerAdapter to the pager object */ 
     pager.setAdapter(pagerAdapter); 
    } 

    @Override 
    public boolean onCreateOptionsMenu(Menu menu) { 
     getMenuInflater().inflate(R.menu.activity_main, menu); 
     return true; 
    } 
} 

MyAdapter：

package com.example.viewpage; 

import android.os.Bundle; 
import android.support.v4.app.Fragment; 
import android.support.v4.app.FragmentManager; 

public class MyAdapter extends android.support.v4.app.FragmentPagerAdapter { 

    final int PAGE_COUNT = 3; 

    public MyAdapter(FragmentManager fm) { 
     super(fm); 
     // TODO Auto-generated constructor stub 
    } 

    @Override 
    public Fragment getItem(int arg0) { 
     // TODO Auto-generated method stub 
     MyFragment myFragment = new MyFragment(); 
     Bundle data = new Bundle(); 
     data.putInt("current_page", arg0 + 1); 
     myFragment.setArguments(data); 
     return myFragment; 
    } 

    @Override 
    public int getCount() { 
     // TODO Auto-generated method stub 
     return PAGE_COUNT; 
    } 

} 

MyFragment：

package com.example.viewpage; 

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

public class MyFragment extends Fragment { 

    private int mCurrentPage; 

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

     /** Getting the arguments to the Bundle object */ 
     Bundle data = getArguments(); 

     /** Getting integer data of the key current_page from the bundle */ 
     mCurrentPage = data.getInt("current_page", 0); 

    } 

    @Override 
    public View onCreateView(LayoutInflater inflater, ViewGroup container, 
      Bundle savedInstanceState) { 
     View v = inflater.inflate(R.layout.frag_layout, container, false); 
     TextView tv = (TextView) v.findViewById(R.id.textView1); 
     tv.setText("You are viewing the page #" + mCurrentPage + "\n\n" 
       + "Swipe Horizontally left/right"); 
     return v; 
    } 
} 

frag_layout.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent" > 

    <TextView 
     android:id="@+id/textView1" 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" 
     android:text="Large Text" 
     android:textAppearance="?android:attr/textAppearanceLarge" /> 

</LinearLayout> 

注：在lib文件夾中添加支持android-support-v4.jar。在Build Path中加入這個罐子。現在去project property-->Build Path--> Order & Export--> select all --> ok。清潔& RUN。
