的Android ViewPager錯誤

Question

我有truble與此代碼：

package com.app.BoomBase; 

import android.app.Activity; 
import android.content.Context; 
import android.os.Bundle; 
import android.os.Parcelable; 
import android.support.v4.view.PagerAdapter; 
import android.support.v4.view.ViewPager; 
import android.view.LayoutInflater; 
import android.view.View; 

public class MainActivity extends Activity { 

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

    MyPagerAdapter adapter = new MyPagerAdapter(); 
    ViewPager myPager = (ViewPager) findViewById(R.id.ViewPager); 
    myPager.setAdapter(adapter); 
    myPager.setCurrentItem(2); 
} 

private class MyPagerAdapter extends PagerAdapter { 
    public int getCount() { 
     return 3; 
} 

public Object instantiateItem(View collection, int position) { 
    LayoutInflater inflater = (LayoutInflater) collection.getContext() 
      .getSystemService(Context.LAYOUT_INFLATER_SERVICE); 

     int resId = 0; 
     switch (position) 
     { 
     case 1: 
       resId = R.layout.beginner; 
       break; 
     case 2: 
       resId = R.layout.activity_main; 
       break; 
     case 3: 
       resId = R.layout.advanced; 
       break; 
     } 

     View view = inflater.inflate(resId, null); 

     ((ViewPager) collection).addView(view, 0); 

     return view; 
} 
@Override 
public void destroyItem(View arg0, int arg1, Object arg2) { 
    ((ViewPager) arg0).removeView((View) arg2); 
} 
@Override 
public boolean isViewFromObject(View arg0, Object arg1) { 
    return arg0 == ((View) arg1); 
} 
@Override 
public Parcelable saveState() { 
    return null; 
} 
} 
} 

和XML文件：

主營：

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

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

</LinearLayout> 

中東：

初學者：

<?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:background="@drawable/background" > 

<ImageButton 
    android:id="@+id/ibWeather" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:layout_alignParentRight="true" 
    android:layout_alignParentTop="true" 
    android:layout_marginRight="68dp" 
    android:layout_marginTop="42dp" 
    android:background="@null" 
    android:src="@drawable/weather_zero_transparrent" /> 

</RelativeLayout> 

和先進：

<?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:background="@drawable/background">  

的問題是，我不斷收到這樣的錯誤：

此錯誤只有當我嘗試滑動到下發生剩下。

任何人都可以幫助我嗎？我迷路了

Answer 1

計數== 3 - >的位置：0，1，2 ...在你開關的情況下，你有1，2和3 ...

取出3，並添加0的情況下;-)

爲您計數：

public int getCount() { 
    return 3; 
} 

那麼你的開關情況必須是這樣的：

int resId = 0; 
    switch (position) 
    { 
    case 0: 
      resId = R.layout.beginner; 
      break; 
    case 1: 
      resId = R.layout.activity_main; 
      break; 
    case 2: 
      resId = R.layout.advanced; 
      break; 
    }
