Question

我在Android上使用Cordova 5.1.1实现了一些问题。我试图在我的应用程序中嵌入CordovaWebView。我已经按照他们的官方site中描述的所有说明操作了，但是我一直收到错误＆＃34; org.apache.cordova.CordovaWebView无法转换为android.view.View ＆＃34 ;.我已经搜索了很多帮助，但我找不到任何可以帮助我的东西。这是我的代码：

的活动：

public class CordovaTestActivity extends Activity implements CordovaInterface {

protected CordovaPlugin activityResultCallback = null;
protected boolean activityResultKeepRunning;
protected boolean keepRunning = true;
private final ExecutorService threadPool = Executors.newCachedThreadPool();
CordovaWebView cwv;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_cordova_test);
    cwv = (CordovaWebView) findViewById(R.id.tutorialView);
    Config.init(this);
    cwv.loadUrl(Config.getStartUrl());
}

@Override
public Activity getActivity() {
    return this;
}

@Override
public ExecutorService getThreadPool() {
    return threadPool;
}

@Override
public Object onMessage(String arg0, Object arg1) {
    return null;
}

@Override
public void setActivityResultCallback(CordovaPlugin plugin) {
    this.activityResultCallback = plugin;
}

@Override
public void startActivityForResult(CordovaPlugin command, Intent intent, int requestCode) {
     this.activityResultCallback = command;
     this.activityResultKeepRunning = this.keepRunning;

     if (command != null) {
         this.keepRunning = false;
     }

     super.startActivityForResult(intent, requestCode);
}

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent intent) {
     super.onActivityResult(requestCode, resultCode, intent);
     CordovaPlugin callback = this.activityResultCallback;
     if (callback != null) {
         callback.onActivityResult(requestCode, resultCode, intent);
     }
} }

的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:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context="com.example.cordovatest.CordovaTestActivity" >

<org.apache.cordova.CordovaWebView
 android:id="@+id/tutorialView"
 android:layout_width="match_parent"
 android:layout_height="match_parent" />

</RelativeLayout>

config.xml中

<widget id="com.example.hello" version="0.0.1" xmlns="http://www.w3.org/ns/widgets" xmlns:cdv="http://cordova.apache.org/ns/1.0">
<preference name="loglevel" value="DEBUG" />
<preference name="AndroidLaunchMode" value="singleTop" />
<name>Hello World</name>

Answer 1

我知道我来不及回答这个问题，但今天我面对这个问题，并试图寻找解决方案。

在5.1.1 cordova的Android实现中，CordovaWebView从CustomwebView转换为接口而我们无法在布局中使用它，这就是应用程序无法编译的原因。

cordova提供的另一个webview实现在org.apache.cordova.engine包下称为SystemWebView。

我不知道为什么cordova开发者将cordovawebview转换为接口

Answer 2

我找到了解决方法。我们可以使用org.apache.cordova.engine.SystemWebView而不是CordovaWebView，它将按预期工作。

CordovaWebView错误：org.apache.cordova.CordovaWebView无法强制转换为android.view.View
