Hello, I am new to android programming...so please be patient.. I am trying to load a custom view (TracciaView) into an activity (Activitygps), where my custom view in defined as a subclass of an activty class. I created the following xml layout file for the activity containing the custom view:
---- <?xml version="1.0" encoding="utf-8"?> <view xmlns:android="http://schemas.android.com/apk/res/android"; class="com.example.android.prova.Activitygps$TracciaView" android:id="@+id/TracciaV" android:layout_width="fill_parent" android:layout_height="fill_parent" /> ---- this is the subclass TracciaView: public static class TracciaView extends View { private ShapeDrawable mDrawable; public TracciaView(Context context) { super(context); int x = 10; int y = 10; int width = 300; int height = 200; mDrawable = new ShapeDrawable(new OvalShape()); mDrawable.getPaint().setColor(0xff74AC23); mDrawable.setBounds(x, y, x + width, y + height); } @Override protected void onDraw(Canvas canvas) { mDrawable.draw(canvas); super.onDraw(canvas); } } What happens is I am keeping on getting runtime error (the app dies), looking in the LogCat I get: I/ActivityManager( 53): Starting activity: Intent { comp= {com1.example.android.prova/com1.example.android.prova.Activitygps} } D/AndroidRuntime( 164): Shutting down VM W/dalvikvm( 164): threadid=3: thread exiting with uncaught exception (group=0x4000fe68) E/AndroidRuntime( 164): Uncaught handler: thread main exiting due to uncaught exception E/AndroidRuntime( 164): java.lang.RuntimeException: Unable to start activity ComponentInfo{com1.example.android.prova/ com1.example.android.prova.Activitygps}: android.view.InflateException: Binary XML file line #2: Error inflating class com.example.android.prova.Activitygps$TracciaView E/AndroidRuntime( 164): at android.app.ActivityThread.performLaunchActivity(ActivityThread.java: 2141) E/AndroidRuntime( 164): at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java: 2157) E/AndroidRuntime( 164): at android.app.ActivityThread.access$1800 (ActivityThread.java:112) E/AndroidRuntime( 164): at android.app.ActivityThread$H.handleMessage (ActivityThread.java:1581) E/AndroidRuntime( 164): at android.os.Handler.dispatchMessage (Handler.java:88) E/AndroidRuntime( 164): at android.os.Looper.loop(Looper.java:123) E/AndroidRuntime( 164): at android.app.ActivityThread.main (ActivityThread.java:3739) E/AndroidRuntime( 164): at java.lang.reflect.Method.invokeNative (Native Method) E/AndroidRuntime( 164): at java.lang.reflect.Method.invoke (Method.java:515) E/AndroidRuntime( 164): at com.android.internal.os.ZygoteInit $MethodAndArgsCaller.run(ZygoteInit.java:739) E/AndroidRuntime( 164): at com.android.internal.os.ZygoteInit.main (ZygoteInit.java:497) E/AndroidRuntime( 164): at dalvik.system.NativeStart.main(Native Method) E/AndroidRuntime( 164): Caused by: android.view.InflateException: Binary XML file line #2: Error inflating class com.example.android.prova.Activitygps$TracciaView E/AndroidRuntime( 164): at android.view.LayoutInflater.createViewFromTag(LayoutInflater.java:575) E/AndroidRuntime( 164): at android.view.LayoutInflater.inflate (LayoutInflater.java:385) E/AndroidRuntime( 164): at android.view.LayoutInflater.inflate (LayoutInflater.java:320) E/AndroidRuntime( 164): at android.view.LayoutInflater.inflate (LayoutInflater.java:276) E/AndroidRuntime( 164): at com.android.internal.policy.impl.PhoneWindow.setContentView (PhoneWindow.java:231) E/AndroidRuntime( 164): at android.app.Activity.setContentView (Activity.java:1567) E/AndroidRuntime( 164): at com1.example.android.prova.Activitygps.onCreate(Activitygps.java:60) E/AndroidRuntime( 164): at android.app.Instrumentation.callActivityOnCreate(Instrumentation.java: 1122) E/AndroidRuntime( 164): at android.app.ActivityThread.performLaunchActivity(ActivityThread.java: 2104) E/AndroidRuntime( 164): ... 11 more E/AndroidRuntime( 164): Caused by: java.lang.ClassNotFoundException: com.example.android.prova.Activitygps$TracciaView in loader dalvik.system.pathclassloa...@4339c200 E/AndroidRuntime( 164): at dalvik.system.PathClassLoader.findClass (PathClassLoader.java:215) E/AndroidRuntime( 164): at java.lang.ClassLoader.loadClass (ClassLoader.java:453) E/AndroidRuntime( 164): at java.lang.ClassLoader.loadClass (ClassLoader.java:421) E/AndroidRuntime( 164): at android.view.LayoutInflater.createView (LayoutInflater.java:465) E/AndroidRuntime( 164): at android.view.LayoutInflater.createViewFromTag(LayoutInflater.java:564) E/AndroidRuntime( 164): ... 19 more I/Process ( 53): Sending signal.
