Crosswalk - Inflating class＆amp; CIE

标签： android webview crosswalk-runtime

我目前正在使用Crosswalk（之前在Cordova上工作）。但我遇到了一个问题：当我创建一个简单的XWalkView时，没有任何作用..

我的意思是，我遵循所有指南，尝试多种方式而不是任何方式。 我正在使用 CrossWalk 12.41.296.9 ARM。

那样：

public class MainActivity extends Activity {
    private static final String url = "file:///android_asset/www/index.html";

    @Override
    public void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.cordova_layout);
        XWalkView webView = (XWalkView) findViewById(R.id.cordova_webview);
        webView.load(url,null);

    }
}

用这个＆＃34; cordova_layout＆＃34; ：

<org.xwalk.core.XWalkView
        xmlns:android="http://schemas.android.com/apk/res/android"
        android:id="@+id/cordova_webview"
        android:layout_width="match_parent"
        android:layout_height="match_parent">    
</org.xwalk.core.XWalkView>

甚至那样

public class MainActivity extends Activity {
    private static final String url = "file:///android_asset/www/index.html";

    @Override
    public void onCreate(Bundle savedInstanceState)   {
        super.onCreate(savedInstanceState);
        XWalkView cordovaWebView = new XWalkView(this.getApplicationContext(),this);
        cordovaWebView.load(url,null);
        setContentView(cordovaWebView);
    }
}

正在给我的膨胀错误

替换此

    XWalkView cordovaWebView = new XWalkView(this.getApplicationContext(),this);
    cordovaWebView.load(url,null);
    setContentView(cordovaWebView);

与

    setContentView(R.layout.cordova_layout);
    XWalkView cordovaWebView = (XWalkView)findViewById(R.id.cordova_webview);
    cordovaWebView.load(url,null);

编辑：这是一个对我有用的例子：

public class MainActivity extends AppCompatActivity {
    private XWalkView xWalkWebView;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        getWindow().requestFeature(Window.FEATURE_PROGRESS);
        getWindow().requestFeature(Window.FEATURE_NO_TITLE);
        getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
            WindowManager.LayoutParams.FLAG_FULLSCREEN
        );
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        xWalkWebView = (XWalkView) findViewById(R.id.xwalkWebView);           
        xWalkWebView.load(url, null);

        // turn on debugging
        // XWalkPreferences.setValue(XWalkPreferences.REMOTE_DEBUGGING, true);
    }

    @Override
    protected void onPause() {
        super.onPause();
        if(xWalkWebView != null) {
            xWalkWebView.pauseTimers();
            xWalkWebView.onHide();
        }
    }

    @Override
    protected void onResume() {
        super.onResume();
        if(xWalkWebView != null) {
            xWalkWebView.resumeTimers();
            xWalkWebView.onShow();
        }
    }

    @Override
    protected void onDestroy() {
        super.onDestroy();
        if(xWalkWebView != null) {
            xWalkWebView.onDestroy();
        }
    }
}

布局：

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
              android:orientation="vertical"
              android:layout_width="fill_parent"
              android:layout_height="fill_parent"
              android:background="#000000">

    <org.xwalk.core.XWalkView
        android:id="@+id/xwalkWebView"
        android:orientation="vertical"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:background="#000000"
        />

</LinearLayout>

清单：

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

    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>

    <uses-permission android:name="android.permission.CAMERA"/>

    <uses-permission android:name="android.permission.WAKE_LOCK"/>
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>


    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/Theme.AppCompat.Light.NoActionBar.FullScreen">

        <activity
            android:name=".MainActivity"
            android:screenOrientation="landscape"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

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

</manifest>

模块级gradle：

android {
    compileSdkVersion 21
    buildToolsVersion "21.1.2"

    defaultConfig {
        applicationId "my.xwalk.thing"
        minSdkVersion 14
        targetSdkVersion 21
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
    packagingOptions {
        // Exclude file to avoid
        // Error: Duplicate files during packaging of APK
        exclude 'META-INF/DEPENDENCIES'
        exclude 'META-INF/LICENSE'
        exclude 'META-INF/LICENSE.txt'
        exclude 'META-INF/license.txt'
        exclude 'META-INF/NOTICE'
        exclude 'META-INF/NOTICE.txt'
        exclude 'META-INF/notice.txt'
        exclude 'META-INF/ASL2.0'
        exclude 'META-INF/services/javax.annotation.processing.Processor'
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:appcompat-v7:21.0.3'
    compile 'org.xwalk:xwalk_core_library_beta:11.40.277.6'
}

和项目级别gradle：

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    repositories {
        jcenter()
        maven {
            url 'https://download.01.org/crosswalk/releases/crosswalk/android/maven2'
        }
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:1.0.1'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        jcenter()
        maven {
            url 'https://download.01.org/crosswalk/releases/crosswalk/android/maven2'
        }
    }
}

请更新过时的Android Gradle插件，支持库，Crosswalk版本和compile / buildtool / targetSDK。
