相关疑难解决方法(0)

我正在使用Android Lollipop(5.0)中使用的新Material Design创建一个应用程序.

我使用以下指南:

• http://android-developers.blogspot.it/2014/10/appcompat-v21-material-design-for-pre.html
• http://antonioleiva.com/material-design-everywhere/

创建工具栏后,我收到此错误:"以下类无法实例化: - android.support.v7.widget.Toolbar"

该应用程序在手机或模拟器中运行良好,但Android Studio的布局设计器无法正确显示布局.

这里有一些图片:

my_awesome_toolbar.xml布局预览中出错

activity_my.xml布局预览出错

文件的xml代码:

my_awesome_toolbar.xml:

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

<android.support.v7.widget.Toolbar
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/my_awesome_toolbar"
android:layout_height="wrap_content"
android:layout_width="match_parent"
android:minHeight="?attr/actionBarSize"
android:background="?attr/colorPrimary" />

activity_my.xml:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
            xmlns:tools="http://schemas.android.com/tools"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:id="@+id/root"
            tools:context="com.myapp.test.MyActivity"
            android:orientation="horizontal">

    <include
        android:id="@+id/toolbar"
        layout="@layout/my_awesome_toolbar"
        />
    <!-- Rest of layout -->
</RelativeLayout>

MyActivity.java:

package com.myapp.test;

import android.os.Bundle;
import android.support.v7.app.ActionBarActivity;
import android.support.v7.widget.Toolbar;
import android.view.Menu;
import android.view.MenuItem;


public class MyActivity extends ActionBarActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_my);

        Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);
    } …

从设计支持库中泄漏任何内容时出错

XML

<android.support.design.widget.FloatingActionButton
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"/>

    }
}

allprojects {
    repositories {
        mavenCentral()
    }
}

错误:

我的Sdk经理一切都是最新的.

我正在开发一个具有滑动功能的Tab的应用程序.我正在使用Eclipse进行开发.我已support design library通过Property 导入了as Library.在运行期间,我不断收到此错误" Error inflating class android.support.design.widget.CoordinatorLayout".

1. 首先,我添加android support design.jar并尝试,这是行不通的
2. 我添加了通过J 的class.jar文件,但是没有用support design libraryava build path
3. 最后我support design library用Properties->Android->Add Library这个导入了as Library 也行不通
4. 我使用父主题为" Theme.AppCompat.Light.DarkActionBar"

" <style name="MyMaterialTheme.Base" parent="Theme.AppCompat.Light.DarkActionBar">"

5. 我正在扩展AppCompatActivity,请参阅我的MainActivity.Java

   package com.example.scrollingtab.activity;

   import android.support.v7.app.AppCompatActivity;
   import android.support.v7.widget.Toolbar;
   import android.widget.Button;
   import com.example.scrollingtab.R;
   
   public class MainActivity extends AppCompatActivity implements View.OnClickListener {
   
       private Toolbar toolbar;
       private Button btnSimpleTabs, btnScrollableTabs, btnIconTextTabs, btnIconTabs, btnCustomIconTextTabs;
   
       @Override
       protected void onCreate(Bundle …

以下是我的配置.这适用于Android Lollipop但在Android Kitkat上崩溃.

我尝试了每个解决方法,但无法帮助:
错误膨胀类android.support.design.widget.NavigationView

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.2"

defaultConfig {

    targetSdkVersion 23

我想念什么？我跟踪了这​​些答案error-inflating-class-android，support-design-widget-navigationview。但还是开始这个​​错误

 Error inflating class android.support.design.widget.BottomNavigationView
Didn't find class "android.support.design.widget.BottomNavigationView" on path: DexPathList[[zip file ...

我的MainActivity包括AppCompatActivity：

public class MainActivity extends AppCompatActivity   implements NavigationView.OnNavigationItemSelectedListener {

我的成绩是：

compile fileTree(dir: 'libs', include: ['*.jar'])
testCompile 'junit:junit:4.12'
compile 'com.android.support:appcompat-v7:23.1.1'
compile 'com.android.support:design:23.1.1'
compile 'com.squareup.okhttp:okhttp:2.5.0'
compile 'com.squareup.picasso:picasso:2.5.2'
compile 'com.android.support:recyclerview-v7:23.0.+'

我的风格是：

<!-- Base application theme. -->
<style name="AppTheme" parent="Base.AppTheme">
    <!-- Customize your theme here. -->
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
