Android Webview 很慢

Question

我尝试添加 http://208.77.22.13/proprek_android/property-listing-trends.php?PropertyID=63&placeId=1&property_type=1&BuildingName=Arabian%20Ranches%20&BedRooms=4

在 webview 中加载速度非常快slow.I在桌面浏览器中尝试加载速度非常快

wv1 = (WebView) findViewById(R.id.webviewdetail);
    WebSettings webSettings = wv1.getSettings();
    webSettings.setLoadsImagesAutomatically(true);
    webSettings.setJavaScriptEnabled(true);
    webSettings.setLoadWithOverviewMode(true);
    webSettings.setRenderPriority(WebSettings.RenderPriority.HIGH);


    if (Build.VERSION.SDK_INT >= 19) {
        // chromium, enable hardware acceleration
        wv1.setLayerType(View.LAYER_TYPE_HARDWARE, null);
    } else {
        // older android version, disable hardware acceleration
        wv1.setLayerType(View.LAYER_TYPE_SOFTWARE, null);
    }

我将此代码添加到 android 但仍然很慢，为什么？

Answer 1

我检查了 URL 您在我的浏览器中提供的内容，加载需要将近 30 秒，因此您的代码没有任何问题

1.build.gradle(Project)

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

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.2.2'

        // 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'}
    } // this is the single line you are adding to project level gradle file.else is generated.
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

build.gradle(app)

apply plugin: 'com.android.application'

android {
    compileSdkVersion 25 //put your desired version
    buildToolsVersion "25.0.0" // put your desired version
    defaultConfig {
        applicationId "com.example.arsensench.xwalk" //put your package name
        minSdkVersion 16 // min sdk should be 16
        targetSdkVersion 25 // target sdk can be your desierd
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    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-v7:25.0.1'
    testCompile 'junit:junit:4.12'
   //until here everything is generated
   //the line below is using the latest XWALK.
compile 'org.xwalk:xwalk_core_library:22.52.561.4'

}

3. AndroidManifest.xml

 <?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.arsensench.xwalk"><!-- your package name-->
    <uses-permission android:name="android.permission.INTERNET"></uses-permission>
    <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">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

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

</manifest>

4.MainActivity.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/activity_main"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="com.example.arsensench.xwalk.MainActivity"> <!--your class path-->

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

5.MainActivity.java()

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import org.xwalk.core.XWalkView;

public class MainActivity extends AppCompatActivity {

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

        XWalkView xWalkWebView=(XWalkView)findViewById(R.id.xwalkWebView);
        xWalkWebView.load("http://208.77.22.13/proprek_android/property-listing-trends.php?PropertyID=63&placeId=1&property_type=1&BuildingName=Arabian%20Ranches%20&BedRooms=4", null);
    }
