如图所示的一个对话框。在preference.xml中的定义如下:
<EditTextPreference
            android:dialogLayout="@layout/custom_preference_dialoglayout"
            android:key="password_st"
            android:summary="@string/mode_hint_pwd_st"
            android:title="@string/mode_content_pwd_st" /> cusom_preference_dialoglayout如下:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:orientation="vertical"
    android:padding="8dp" >
    <EditText
        android:id="@+id/idFsSettingOldPwd"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:ellipsize="end"
        android:hint="@string/oldpwd_hint_st"
        android:maxLines="1"
        android:singleLine="true" />
    <EditText
        android:id="@+id/idFsSettingNewPwd1"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:ellipsize="end"
        android:hint="@string/newpwd_hint_st"
        android:maxLines="1"
        android:singleLine="true" />
    <EditText
        android:id="@+id/idFsSettingNewPwd2"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:ellipsize="end"
        android:hint="@string/newpwd2_hint_st"
        android:maxLines="1"
        android:singleLine="true" />
</LinearLayout>
请问下该如何在PreferenceActivity中获取三个输入框输入的值呢。谢谢各位了。
