La mia PreferenceActivity non viene visualizzata, anche se è nel mio file manifest

StackOverflow https://stackoverflow.com/questions/2614134

Domanda

Quindi sto modificando l'esempio dello sfondo animato Cube.Ho una classe che estende PreferenceActivity e ho aggiunto l'attività nel mio file manifest.Continuo a ricevere ActivityNotFoundExceptions.

Ecco la mia classe di preferenza: 

package com.p.t.wallpapers.mywallpaper;

import com.p.t.wallpapers.mywallpaper.R;
import android.content.SharedPreferences;
import android.os.Bundle;
import android.preference.PreferenceActivity;

public class MySettingsActivity extends PreferenceActivity
implements SharedPreferences.OnSharedPreferenceChangeListener {

@Override
protected void onCreate(Bundle bundle) {
    super.onCreate(bundle);
    getPreferenceManager().setSharedPreferencesName(
            ParticleCandy.SHARED_PREFS_NAME);
    addPreferencesFromResource(R.xml.settings);
    getPreferenceManager().getSharedPreferences().registerOnSharedPreferenceChangeListener(
            this);
}

@Override
protected void onResume() {
    super.onResume();
}

@Override
protected void onDestroy() {
    getPreferenceManager().getSharedPreferences().unregisterOnSharedPreferenceChangeListener(
            this);
    super.onDestroy();
}

public void onSharedPreferenceChanged(SharedPreferences sharedPreferences,
        String key) {
}

}

Ed ecco il mio file manifest

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
  package="com.p.t.wallpapers.mywallpaper"
  android:versionCode="1"
  android:versionName="1.0">
<application android:icon="@drawable/icon" android:label="@string/app_name">
<service 
 android:label="@string/app_name" 
 android:name=".MyWallpaper" 
 android:permission="android.permission.BIND_WALLPAPER" >
 <intent-filter>
  <action 
   android:name="android.service.wallpaper.WallpaperService">
  </action>
</intent-filter>
<meta-data 
    android:name="android.service.wallpaper" 
    android:resource="@xml/wallpaper_info" />  
</service>

<activity
  android:label="@string/settings_title"
    android:name=".MySettingsActivity"
    android:theme="@android:style/Theme.Light.WallpaperSettings"
   android:exported="true">
</activity>

</application>
<uses-sdk android:minSdkVersion="7" />
<uses-feature android:name="android.software.live_wallpaper" />
</manifest>

Qualche idea sul motivo per cui la mia attività di preferenza non viene letta dal manifest?Il servizio di sfondi, MyWallpaper, si presenta bene, ma DDMS continua a dirmi che l'attività MySettingsActivity non esce.

Ecco l'output di logcat

È stato utile?

Soluzione

Capito.È l'xml dello sfondo a cui si fa riferimento nel manifest, sotto il tag dei metadati nel tag di servizio.Fondamentalmente, quell'xml ha 

<wallpaper 
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:settingsActivity="MySettingsActivity"/>

Noti la "MySettingsActivity" lì?Sì, poiché questo è un file separato dal manifest, non ha automaticamente un pacchetto da cui inizia a cercare i nomi delle classi.Quindi tutto quello che dovevo fare era inserire il percorso completo del pacchetto, in questo modo

<wallpaper 
xmlns:android="http://schemas.android.com/apk/res/android"
android:settingsActivity="com.p.t.wallpapers.mywallpaper.MySettingsActivity" />

e voilà!La schermata delle mie preferenze viene visualizzata ora quando premo Impostazioni...pulsante, invece di forzare l'arresto anomalo.Oddio, facepalm!

Altri suggerimenti

Vorrei aggiungere un punto iniziale sui vostri attributi android:name (ad esempio, android:name=".MySettingsActivity") o completamente qualificare il loro pacchetto (ad esempio, android:name="com.p.t.wallpapers.mywallpaper.MySettingsActivity").

Inoltre, mi sarebbe sbarazzarsi del import com.p.t.wallpapers.mywallpaper.R, in quanto non dovrebbe essere necessario (siete già in quel pacchetto) e potrebbe essere mascherare un problema pacchetto.

Se nessuna di quelle di aiuto, si prega di aggiornare la tua domanda a spiegare dove, esattamente, si stanno ottenendo il ActivityNotFoundExceptions.

Prima risposta vale a dire l'aggiunta di

è corretto. questo dovrebbe essere aggiunto nel file XML che descrive il tag.

se si vuole sbarazzarsi delle impostazioni in crash eliminare il Android:. tag settingActivity dallo stesso file

Assicurati che il tuo MySettingsActivity è nel pacchetto com.p.t.wallpapers.mywallpaper, altrimenti è necessario specificare il nome del pacchetto assoluto.
