I have the exact the problem. I simply cut and post the tutorial from the Android Developer site.
Here is my main.xml and java code. <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/ android" android:layout_width="wrap_content" android:layout_height="wrap_content" android:orientation="vertical"> <TextView android:id="@+id/dateDisplay" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text=""/> <Button android:id="@+id/pickDate" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Change the date"/> </LinearLayout> import android.app.Activity; import android.app.DatePickerDialog; import android.os.Bundle; import android.widget.TextView; import android.widget.Button; import android.widget.DatePicker; import android.view.View; import java.util.Calendar; public class HelloDatePicker extends Activity { private TextView mDateDisplay; private Button mPickDate; private int mYear; private int mMonth; private int mDay; static final int DATE_DIALOG_ID = 0; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); // capture our View elements mDateDisplay = (TextView) findViewById(R.id.dateDisplay); mPickDate = (Button) findViewById(R.id.pickDate); // add a click listener to the button mPickDate.setOnClickListener(new View.OnClickListener() { public void onClick(View v) { showDialog(DATE_DIALOG_ID); } }); // get the current date final Calendar c = Calendar.getInstance(); mYear = c.get(Calendar.YEAR); mMonth = c.get(Calendar.MONTH); mDay = c.get(Calendar.DAY_OF_MONTH); // display the current date updateDisplay(); } // updates the date we display in the TextView private void updateDisplay() { mDateDisplay.setText( new StringBuilder() // Month is 0 based so add 1 .append(mMonth + 1).append("-") .append(mDay).append("-") .append(mYear).append(" ")); } // the callback received when the user "sets" the date in the dialog private DatePickerDialog.OnDateSetListener mDateSetListener = new DatePickerDialog.OnDateSetListener() { public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) { mYear = year; mMonth = monthOfYear; mDay = dayOfMonth; updateDisplay(); } }; } Here is the log from catlog: /ActivityManager( 52): Starting activity: Intent { act=android.intent.action.MAIN cat= [android.intent.category.LAUNCHER] flg=0x10200000 cmp=com.chesterxgchen.example1/.HelloDatePicker } I/ActivityManager( 52): Start proc com.chesterxgchen.example1 for activity com.chesterxgchen.example1/.HelloDatePicker: pid=259 uid=10024 gids={1015} I/ActivityManager( 52): Displayed activity com.chesterxgchen.example1/.HelloDatePicker: 1047 ms (total 1047 ms) D/dalvikvm( 100): GC freed 112 objects / 4896 bytes in 110ms I/dalvikvm( 259): threadid=7: reacting to signal 3 E/dalvikvm( 259): Unable to open stack trace file '/data/anr/ traces.txt': Permission denied D/AndroidRuntime( 259): Shutting down VM W/dalvikvm( 259): threadid=3: thread exiting with uncaught exception (group=0x4001b188) E/AndroidRuntime( 259): Uncaught handler: thread main exiting due to uncaught exception E/AndroidRuntime( 259): java.lang.IllegalArgumentException: Activity#onCreateDialog did not create a dialog for id 0 E/AndroidRuntime( 259): at android.app.Activity.createDialog (Activity.java:871) E/AndroidRuntime( 259): at android.app.Activity.showDialog (Activity.java:2483) E/AndroidRuntime( 259): at com.chesterxgchen.example1.HelloDatePicker $1.onClick(HelloDatePicker.java:37) E/AndroidRuntime( 259): at android.view.View.performClick(View.java: 2364) E/AndroidRuntime( 259): at android.view.View.onTouchEvent(View.java: 4179) E/AndroidRuntime( 259): at android.widget.TextView.onTouchEvent (TextView.java:6540) E/AndroidRuntime( 259): at android.view.View.dispatchTouchEvent (View.java:3709) E/AndroidRuntime( 259): at android.view.ViewGroup.dispatchTouchEvent (ViewGroup.java:884) E/AndroidRuntime( 259): at android.view.ViewGroup.dispatchTouchEvent (ViewGroup.java:884) E/AndroidRuntime( 259): at android.view.ViewGroup.dispatchTouchEvent (ViewGroup.java:884) E/AndroidRuntime( 259): at android.view.ViewGroup.dispatchTouchEvent (ViewGroup.java:884) E/AndroidRuntime( 259): at com.android.internal.policy.impl.PhoneWindow $DecorView.superDispatchTouchEvent(PhoneWindow.java:1659) E/AndroidRuntime( 259): at com.android.internal.policy.impl.PhoneWindow.superDispatchTouchEvent (PhoneWindow.java:1107) E/AndroidRuntime( 259): at android.app.Activity.dispatchTouchEvent (Activity.java:2061) E/AndroidRuntime( 259): at com.android.internal.policy.impl.PhoneWindow $DecorView.dispatchTouchEvent(PhoneWindow.java:1643) E/AndroidRuntime( 259): at android.view.ViewRoot.handleMessage (ViewRoot.java:1691) E/AndroidRuntime( 259): at android.os.Handler.dispatchMessage (Handler.java:99) E/AndroidRuntime( 259): at android.os.Looper.loop(Looper.java:123) E/AndroidRuntime( 259): at android.app.ActivityThread.main (ActivityThread.java:4363) E/AndroidRuntime( 259): at java.lang.reflect.Method.invokeNative (Native Method) E/AndroidRuntime( 259): at java.lang.reflect.Method.invoke (Method.java:521) E/AndroidRuntime( 259): at com.android.internal.os.ZygoteInit $MethodAndArgsCaller.run(ZygoteInit.java:860) E/AndroidRuntime( 259): at com.android.internal.os.ZygoteInit.main (ZygoteInit.java:618) E/AndroidRuntime( 259): at dalvik.system.NativeStart.main(Native Method) I/Process ( 52): Sending signal.
