Body
copied!<p>I've been trying to create a Pager for my application that runs on <code><uses-sdk android:minSdkVersion="10" android:targetSdkVersion="15" /></code> I wrote my code according to <a href="http://mobile.tutsplus.com/tutorials/android/android-user-interface-design-horizontal-view-paging/">this blog post</a>. </p> <p><strong>XML for Pager activity:</strong></p> <pre><code><?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" > <android.support.v4.view.ViewPager android:id="@+id/instructionsViewPager" android:layout_width="match_parent" android:layout_height="match_parent" /> </LinearLayout> </code></pre> <p><strong>Code for adapter:</strong></p> <pre><code>public class MyPagerAdapter extends PagerAdapter { @Override public int getCount() { // TODO Auto-generated method stub return 2; } @Override public boolean isViewFromObject(View arg0, Object arg1) { return (arg0 == ((View) arg1)); } @Override public void destroyItem(ViewGroup container, int position, Object object) { ((ViewPager) container).removeView((View) object); } @Override public Object instantiateItem(ViewGroup container, int position) { LayoutInflater inflater = (LayoutInflater) container.getContext() .getSystemService(Context.LAYOUT_INFLATER_SERVICE); int resId = 0; switch (position) { case 1: resId = R.layout.instructions_page1; break; case 2: resId = R.layout.instructions_page2; break; } View view = inflater.inflate(resId, null); ((ViewPager) container).addView(view, 0); return view; } } </code></pre> <p><strong>Code for activity</strong></p> <pre><code>public class Instructions extends Activity { public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.instructions); MyPagerAdapter adapter = new MyPagerAdapter(); ViewPager pager = (ViewPager) findViewById(R.id.instructionsViewPager); pager.setAdapter(adapter); pager.setCurrentItem(0); } } </code></pre> <p>for some reason, when I run this app, I get this following error list:</p> <pre><code>05-28 09:38:54.535: E/AndroidRuntime(18658): FATAL EXCEPTION: main 05-28 09:38:54.535: E/AndroidRuntime(18658): java.lang.RuntimeException: Unable to start activity ComponentInfo{com.thepoosh/com.thepoosh.Instructions}: android.view.InflateException: Binary XML file line #7: Error inflating class android.support.v4.view.ViewPager 05-28 09:38:54.535: E/AndroidRuntime(18658): at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:1651) 05-28 09:38:54.535: E/AndroidRuntime(18658): at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:1667) 05-28 09:38:54.535: E/AndroidRuntime(18658): at android.app.ActivityThread.access$1500(ActivityThread.java:117) 05-28 09:38:54.535: E/AndroidRuntime(18658): at android.app.ActivityThread$H.handleMessage(ActivityThread.java:935) 05-28 09:38:54.535: E/AndroidRuntime(18658): at android.os.Handler.dispatchMessage(Handler.java:99) 05-28 09:38:54.535: E/AndroidRuntime(18658): at android.os.Looper.loop(Looper.java:123) 05-28 09:38:54.535: E/AndroidRuntime(18658): at android.app.ActivityThread.main(ActivityThread.java:3691) 05-28 09:38:54.535: E/AndroidRuntime(18658): at java.lang.reflect.Method.invokeNative(Native Method) 05-28 09:38:54.535: E/AndroidRuntime(18658): at java.lang.reflect.Method.invoke(Method.java:507) 05-28 09:38:54.535: E/AndroidRuntime(18658): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:847) 05-28 09:38:54.535: E/AndroidRuntime(18658): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:605) 05-28 09:38:54.535: E/AndroidRuntime(18658): at dalvik.system.NativeStart.main(Native Method) 05-28 09:38:54.535: E/AndroidRuntime(18658): Caused by: android.view.InflateException: Binary XML file line #7: Error inflating class android.support.v4.view.ViewPager 05-28 09:38:54.535: E/AndroidRuntime(18658): at android.view.LayoutInflater.createViewFromTag(LayoutInflater.java:581) 05-28 09:38:54.535: E/AndroidRuntime(18658): at android.view.LayoutInflater.rInflate(LayoutInflater.java:623) 05-28 09:38:54.535: E/AndroidRuntime(18658): at android.view.LayoutInflater.inflate(LayoutInflater.java:408) 05-28 09:38:54.535: E/AndroidRuntime(18658): at android.view.LayoutInflater.inflate(LayoutInflater.java:320) 05-28 09:38:54.535: E/AndroidRuntime(18658): at android.view.LayoutInflater.inflate(LayoutInflater.java:276) 05-28 09:38:54.535: E/AndroidRuntime(18658): at com.android.internal.policy.impl.PhoneWindow.setContentView(PhoneWindow.java:207) 05-28 09:38:54.535: E/AndroidRuntime(18658): at android.app.Activity.setContentView(Activity.java:1663) 05-28 09:38:54.535: E/AndroidRuntime(18658): at com.thepoosh.Instructions.onCreate(Instructions.java:11) 05-28 09:38:54.535: E/AndroidRuntime(18658): at android.app.Instrumentation.callActivityOnCreate(Instrumentation.java:1047) 05-28 09:38:54.535: E/AndroidRuntime(18658): at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:1615) 05-28 09:38:54.535: E/AndroidRuntime(18658): ... 11 more 05-28 09:38:54.535: E/AndroidRuntime(18658): Caused by: java.lang.ClassNotFoundException: android.support.v4.view.ViewPager in loader dalvik.system.PathClassLoader[/data/app/com.thepoosh-1.apk] 05-28 09:38:54.535: E/AndroidRuntime(18658): at dalvik.system.PathClassLoader.findClass(PathClassLoader.java:240) 05-28 09:38:54.535: E/AndroidRuntime(18658): at java.lang.ClassLoader.loadClass(ClassLoader.java:551) 05-28 09:38:54.535: E/AndroidRuntime(18658): at java.lang.ClassLoader.loadClass(ClassLoader.java:511) 05-28 09:38:54.535: E/AndroidRuntime(18658): at android.view.LayoutInflater.createView(LayoutInflater.java:471) 05-28 09:38:54.535: E/AndroidRuntime(18658): at android.view.LayoutInflater.createViewFromTag(LayoutInflater.java:570) 05-28 09:38:54.535: E/AndroidRuntime(18658): ... 20 more </code></pre> <p>so, I know it's failing because I'm using the <code>android.support.v4.view.ViewPager</code>, I tried playing with that and changing to plain <code>ViewPager</code> and importing <code>android.support.v13</code> but it didn't help...</p> <p>any thoughts on how to fix this?</p>
