我目前正在向我的应用程序添加首选项/设置活动。我一直遇到问题。该preference.xml文件加载正常，但是一旦我尝试单击列表首选项或Edit Text首选项，它就会使用以下堆栈跟踪使活动崩溃：

看起来崩溃是由于dialog_background_material.xml不存在而引起的，但是通过无数示例都没有提到需要添加这样的文件，所以我认为它是 sdk 或 gradle 应该添加的文件。
这是我的 Gradle 文件：
apply plugin: 'com.android.application'
android {
compileSdkVersion 25
buildToolsVersion "25.0.0"
defaultConfig {
applicationId "com.example.benhouse.weatherview"
minSdkVersion 16
targetSdkVersion 23
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
vectorDrawables.useSupportLibrary = true
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2',
{
exclude group: 'com.android.support', module: 'support-annotations'
})
compile 'com.android.support:appcompat-v7:25.3.1'
compile 'com.android.support.constraint:constraint-layout:1.0.2'
compile 'com.github.bumptech.glide:glide:3.5.2'
compile 'com.android.support:support-v4:25.0.0'
compile 'com.android.support:design:25.3.1'
compile 'com.jsibbold:zoomage:1.1.0'
compile 'com.android.support:support-vector-drawable:25.3.1'
testCompile 'junit:junit:4.12'
}
我的prefFragment：
import android.os.Bundle;
import android.preference.PreferenceFragment;
public class PrefsFragment extends PreferenceFragment {
@Override
public void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
// Load the preferences from an XML resource
addPreferencesFromResource(R.xml.preference);
}
}
preference.xml：
<?xml version="1.0" encoding="utf-8"?>
<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android">
<PreferenceCategory
android:title="PreferenceCategory A">
<CheckBoxPreference
android:key="checkbox_preference"
android:title="title_checkbox_preference"
android:summary="summary_checkbox_preference" />
</PreferenceCategory>
<PreferenceCategory
android:title="PreferenceCategory B">
<EditTextPreference
android:key="edittext_preference"
android:title="title_edittext_preference"
android:summary="summary_edittext_preference"
android:dialogTitle="dialog_title_edittext_preference" />
</PreferenceCategory>
<PreferenceCategory
android:title="ListPreference">
<ListPreference
android:key="list_preference"
android:title="title_list_preference"
android:summary="summary_list_preference"
android:entries="@array/listDisplayWord"
android:entryValues="@array/listReturnValue"
android:dialogTitle="dialog_title_list_preference" />
</PreferenceCategory>
</PreferenceScreen>
我真的很难过，因为我浏览了这么多示例和问题，没有人提到这样的问题，并使用类似的代码来让他们的屏幕正常工作。
