我尝试使用( android4devs )下面的素材导航抽屉:
http://www.android4devs.com/2014/12/how-to-make-material-design-navigation-drawer.html
所以,这是我的主要活动:
<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/DrawerLayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:elevation="7dp">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<include
android:id="@+id/tool_bar"
layout="@layout/tool_bar">
</include>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Hello World" />
</LinearLayout>
<android.support.v7.widget.RecyclerView
android:id="@+id/RecyclerView"
android:layout_width="320dp"
android:layout_height="match_parent"
android:layout_gravity="left"
android:background="#ffffff"
android:scrollbars="vertical">
</android.support.v7.widget.RecyclerView>
</android.support.v4.widget.DrawerLayout>
我需要像下面的教程那样做:
主要活动上有类似的事情: https://farm8.staticflickr.com/7506/15428801864_5b4a709e38_b.jpg我尝试了这个和其他方法但我无法在主要活动上准确显示cardview:
<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:card_view="http://schemas.android.com/apk/res-auto"
android:id="@+id/DrawerLayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:elevation="7dp">
<android.support.v7.widget.CardView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
card_view:contentPadding="16dp"
card_view:cardElevation="2dp"
card_view:cardCornerRadius="5dp">
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<include
android:id="@+id/tool_bar"
layout="@layout/tool_bar">
</include>
<TextView
style="@style/Base.TextAppearance.AppCompat.Headline"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Title" />
<TextView
style="@style/Base.TextAppearance.AppCompat.Body1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Content here" />
</LinearLayout>
</android.support.v7.widget.CardView>
<android.support.v7.widget.RecyclerView
android:id="@+id/RecyclerView"
android:layout_width="320dp"
android:layout_height="match_parent"
android:layout_gravity="left"
android:background="#ffffff"
android:scrollbars="vertical">
</android.support.v7.widget.RecyclerView>
</android.support.v4.widget.DrawerLayout>
我认为,之间存在问题
添加cardview之前:

结果后的图片(添加了卡片视图):

并且我的android工作室预览有问题,所以我看不到这一点,但是当我需要看到结果时,我不得不在模拟器上运行它...
关于预览和错误的问题:
android.support.v7.internal.widget.ActionBarOverlayLayout could not be Found 以及这项主要活动:
The following classes could not be found:
- android.support.v4.widget.DrawerLayout (Fix Build Path, Create Class)
- android.support.v7.widget.CardView (Fix Build Path, Create Class)
Tip: Try to build the project.
Build.gradle:
apply plugin: 'com.android.application'
android {
compileSdkVersion 22
buildToolsVersion "22.0.0"
defaultConfig {
applicationId "com.client.test"
minSdkVersion 15
targetSdkVersion 22
versionCode 1
versionName "1.0"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:22.1.1'
compile 'com.android.support:recyclerview-v7:22.0.0'
compile 'com.android.support:cardview-v7:22.0.0'
compile 'de.hdodenhof:circleimageview:1.2.1'
}
顺便说一下,
如何在MainActivity上添加此卡片视图?
干杯!

尝试将您的布局文件更改为此,看看您是否发现任何差异。
