在Samsung Galaxy S上调用RingTonePreference时出现NullPointerException

我在三星Galaxy上调用RingTonePreference时收到以下消息(一切在其他手机上运行正常):

java.lang.RuntimeException: Unable to start activity ComponentInfo{android/com.a ndroid.internal.app.RingtonePickerActivity}: java.lang.NullPointerException at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2663) at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:2679) at android.app.ActivityThread.access$2300(ActivityThread.java:125) at android.app.ActivityThread$H.handleMessage(ActivityThread.java:2033) at android.os.Handler.dispatchMessage(Handler.java:99) at android.os.Looper.loop(Looper.java:123) at android.app.ActivityThread.main(ActivityThread.java:4627) at java.lang.reflect.Method.invokeNative(Native Method) at java.lang.reflect.Method.invoke(Method.java:521) at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:85 8) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:616) at dalvik.system.NativeStart.main(Native Method) Caused by: java.lang.NullPointerException at com.android.internal.app.RingtonePickerActivity.onPrepareListView(RingtonePic kerActivity.java:252) at com.android.internal.app.AlertController$AlertParams.createListView(AlertCont roller.java:909) at com.android.internal.app.AlertController$AlertParams.apply(AlertController.ja va:824) at com.android.internal.app.AlertActivity.setupAlert(AlertActivity.java:73) at com.android.internal.app.RingtonePickerActivity.onCreate(RingtonePickerActivi ty.java:226) at android.app.Instrumentation.callActivityOnCreate(Instrumentation.java:1049) at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2627) ... 11 more 

更新 :以下是它的调用方式:

   

PS:我知道有一个类似的问题已被提出,但没有给出答案( https://stackoverflow.com/questions/5428768/notification-or-alarm-sound-picker-crash-on-galaxy-s/5872352 #5872352 )

通过在定义中设置“showSilent = true”来解决此问题,并且显然是Galaxy S特有的错误。
