Question

由于其他人在看教程以学习如何在android中编写代码的东西时，我看了this tutorial。我在AndroidStudio中创建了一个新项目，并将activity_main.xml替换为如下所示的代码（并且没有更改任何其他内容）：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

    <ListView
        android:id="@+id/list"
        android:layout_height="wrap_content"
        android:layout_width="match_parent">
    </ListView>

</LinearLayout>

这会导致预览消失，但会出现渲染问题：

 Rendering Problems Missing styles. Is the correct theme chosen for this layout?  Use the Theme combo box above the layout to choose a different layout, or fix the theme style references.  Failed to find style 'listViewStyle' in current theme (6 similar errors not shown) "?attr/listPreferredItemHeight" in attribute "minHeight" is not a valid format. (Edit) (3 similar errors not shown)

如何解决这个问题？或者是否有一个教程，一个如何在某处使用ListView的完整工作示例？

清单：

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.alexander.testapplication" >

    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:supportsRtl="true"
        android:theme="@style/AppTheme" >
        <activity
            android:name=".MainActivity"
            android:label="@string/app_name"
            android:theme="@style/AppTheme.NoActionBar" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

</manifest>

gradle.build：

apply plugin: 'com.android.application'

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.1"

    defaultConfig {
        applicationId "com.example.alexander.testapplication"
        minSdkVersion 15
        targetSdkVersion 23
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:23.1.0'
    compile 'com.android.support:design:23.1.0'
}
