POLoading a TextView from xml into a TextSwitcher

copied!<p>I've been trying to setup a TextSwitcher with the TextView loading in from an xml file. I have this basic TextSwitcher example that uses an empty TextView working ok:</p> <pre><code>.java public class TextSwitcherTest extends Activity { private TextSwitcher textSwitcher; private ViewFactory viewFactory = new ViewFactory() { public View makeView() { TextView textView = new TextView(TextSwitcherTest.this); return textView; } }; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); textSwitcher = (TextSwitcher) findViewById(R.id.textSwitcher); textSwitcher.setFactory(viewFactory); Animation in = AnimationUtils.loadAnimation(this,android.R.anim.fade_in); Animation out = AnimationUtils.loadAnimation(this,android.R.anim.fade_out); textSwitcher.setInAnimation(in); textSwitcher.setOutAnimation(out); textSwitcher.setText("test ok"); } } </code></pre> <p>-</p> <pre><code>main.xml <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical" > <TextSwitcher android:id="@+id/textSwitcher" android:layout_width="fill_parent" android:layout_height="wrap_content" /> </LinearLayout> </code></pre> <hr> <p>But when I change the code to try and load a TextView from an xml file, it spits out a pile of errors. Here's the amended code:</p> <pre><code>.java public class TextSwitcherTest extends Activity { private TextSwitcher textSwitcher; private ViewFactory viewFactory = new ViewFactory() { public View makeView() { LayoutInflater inflater = LayoutInflater.from(TextSwitcherTest.this); TextView textView = (TextView) inflater.inflate(R.id.textView,null); return textView; } }; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); textSwitcher = (TextSwitcher) findViewById(R.id.textSwitcher); textSwitcher.setFactory(viewFactory); Animation in = AnimationUtils.loadAnimation(this,android.R.anim.fade_in); Animation out = AnimationUtils.loadAnimation(this,android.R.anim.fade_out); textSwitcher.setInAnimation(in); textSwitcher.setOutAnimation(out); textSwitcher.setText("test ok"); } } </code></pre> <p>-</p> <pre><code>textview.xml <?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" > <TextView android:id="@+id/textView" android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="@string/hello" /> </LinearLayout> </code></pre> <p>Can anyone offer a suggestion where I'm going wrong? The code compiles ok but I'm sure it's with the LayoutInflater being misused in some way?</p> <hr> <p>error messages (it didn't display the '11 more'):</p> <pre><code>07-22 03:51:24.096: W/dalvikvm(580): threadid=1: thread exiting with uncaught exception (group=0x409c01f8) 07-22 03:51:24.137: E/AndroidRuntime(580): FATAL EXCEPTION: main 07-22 03:51:24.137: E/AndroidRuntime(580): java.lang.RuntimeException: Unable to start activity ComponentInfo{test09.TextSwitcher01/test09.TextSwitcher01.TextSwitcherTest}: android.content.res.Resources$NotFoundException: Resource ID #0x7f050001 type #0x12 is not valid 07-22 03:51:24.137: E/AndroidRuntime(580): at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:1956) 07-22 03:51:24.137: E/AndroidRuntime(580): at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:1981) 07-22 03:51:24.137: E/AndroidRuntime(580): at android.app.ActivityThread.access$600(ActivityThread.java:123) 07-22 03:51:24.137: E/AndroidRuntime(580): at android.app.ActivityThread$H.handleMessage(ActivityThread.java:1147) 07-22 03:51:24.137: E/AndroidRuntime(580): at android.os.Handler.dispatchMessage(Handler.java:99) 07-22 03:51:24.137: E/AndroidRuntime(580): at android.os.Looper.loop(Looper.java:137) 07-22 03:51:24.137: E/AndroidRuntime(580): at android.app.ActivityThread.main(ActivityThread.java:4424) 07-22 03:51:24.137: E/AndroidRuntime(580): at java.lang.reflect.Method.invokeNative(Native Method) 07-22 03:51:24.137: E/AndroidRuntime(580): at java.lang.reflect.Method.invoke(Method.java:511) 07-22 03:51:24.137: E/AndroidRuntime(580): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:784) 07-22 03:51:24.137: E/AndroidRuntime(580): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:551) 07-22 03:51:24.137: E/AndroidRuntime(580): at dalvik.system.NativeStart.main(Native Method) 07-22 03:51:24.137: E/AndroidRuntime(580): Caused by: android.content.res.Resources$NotFoundException: Resource ID #0x7f050001 type #0x12 is not valid 07-22 03:51:24.137: E/AndroidRuntime(580): at android.content.res.Resources.loadXmlResourceParser(Resources.java:2110) 07-22 03:51:24.137: E/AndroidRuntime(580): at android.content.res.Resources.getLayout(Resources.java:857) 07-22 03:51:24.137: E/AndroidRuntime(580): at android.view.LayoutInflater.inflate(LayoutInflater.java:394) 07-22 03:51:24.137: E/AndroidRuntime(580): at android.view.LayoutInflater.inflate(LayoutInflater.java:352) 07-22 03:51:24.137: E/AndroidRuntime(580): at test09.TextSwitcher01.TextSwitcherTest$1.makeView(TextSwitcherTest.java:23) 07-22 03:51:24.137: E/AndroidRuntime(580): at android.widget.ViewSwitcher.obtainView(ViewSwitcher.java:80) 07-22 03:51:24.137: E/AndroidRuntime(580): at android.widget.ViewSwitcher.setFactory(ViewSwitcher.java:99) 07-22 03:51:24.137: E/AndroidRuntime(580): at test09.TextSwitcher01.TextSwitcherTest.onCreate(TextSwitcherTest.java:38) 07-22 03:51:24.137: E/AndroidRuntime(580): at android.app.Activity.performCreate(Activity.java:4465) 07-22 03:51:24.137: E/AndroidRuntime(580): at android.app.Instrumentation.callActivityOnCreate(Instrumentation.java:1049) 07-22 03:51:24.137: E/AndroidRuntime(580): at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:1920) 07-22 03:51:24.137: E/AndroidRuntime(580): ... 11 more </code></pre>
