我想在设置中使用Seekbar选择数字1到10.有没有办法做到这一点？我延长PreferenceActivity了我的设置活动.

正如我从这里发现的那样,但我不知道如何在里面创建Seekbar PreferenceScreen.预先感谢.这是活动

 public class UserSettingActivity extends PreferenceActivity {
    @Override

    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);        

         addPreferencesFromResource(R.xml.settings);    }
}

和setting.xml

 <?xml version="1.0" encoding="utf-8"?>

<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android" >

 

    <PreferenceCategory android:title="@string/pref_user_profile" >

        <EditTextPreference

                android:title="@string/pref_user_name"

                android:summary="@string/pref_user_name_summary"

                android:key="prefUsername"/>

    </PreferenceCategory>

     

    <PreferenceCategory android:title="@string/pref_update_setting" >

        <CheckBoxPreference

            android:defaultValue="false"

            android:key="prefSendReport"

            android:summary="@string/pref_send_report_summary"

            android:title="@string/pref_send_report" >

        </CheckBoxPreference>

 

        <ListPreference

            android:key="prefSyncFrequency"

            android:entries="@array/syncFrequency"

            android:summary="@string/pref_sync_frequency_summary"

            android:entryValues="@array/syncFrequencyValues"

            android:title="@string/pref_sync_frequency" />

    </PreferenceCategory>

 

</PreferenceScreen>
