java - 如何在 Android webview 中检测到 url 时更改 Activity

Question

当在我的 Android 应用程序的 web View 中检测到 URL 时，我尝试更改 Activity。我收到此错误:

Unable to start activity ComponentInfo{"xxx"}: android.content.ActivityNotFoundException: No Activity found to handle Intent { act=Open.Tok.Act }

这是我的AndroidManifest.xml

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

    <uses-sdk
        android:minSdkVersion="16"
        android:targetSdkVersion="17" />

    <!-- To auto-complete the email text field in the login form with the user's emails -->
    <uses-permission android:name="android.permission.GET_ACCOUNTS" />
    <uses-permission android:name="android.permission.READ_PROFILE" />
    <uses-permission android:name="android.permission.READ_CONTACTS" />
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>

    <!-- Using the camera -->
    <uses-permission android:name="android.permission.CAMERA" />
    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.RECORD_AUDIO" />
    <uses-permission android:name="android.permission.MODIFY_AUDIO_SETTINGS" />

    <uses-feature android:name="android.hardware.camera" />
    <uses-feature android:name="android.hardware.camera.autofocus" />


    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="a"
        android:theme="@style/AppTheme"
        >
        <activity android:name=".OpenTokActivity" android:configChanges="orientation|keyboardHidden|screenSize">
            <intent-filter>
                <action android:name="Open.Tok.Act" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <activity android:name=".WebViewActivity" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

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

</manifest>

这是我的 WebView 代码:

aWebView.setWebViewClient(new WebViewClient(){

    @Override
    public boolean shouldOverrideUrlLoading(WebView view, String url) {
        return super.shouldOverrideUrlLoading(view, url);
    }

    @Override
    public void onPageStarted(WebView view, String url, Bitmap favicon) {
        super.onPageStarted(view, url, favicon);
    }

    @Override
    public void onPageFinished(WebView view, String url) {
        super.onPageFinished(view, url);

        if(url.equals("http://95.85.53.176/nhi/booktid"))
        {
            Log.d(LOGTAG, "GO TO OPENTOK!!!");
            startActivity(new Intent("OpenTokAct"));
        }
        Log.d(LOGTAG,"current URL = " + url);

    }



});

aWebView.loadUrl(mainUrl);

我也在onCreate()的开头尝试过这个，但它给了我同样的错误......

Intent openStartingPoint = new Intent("Open.Tok.Act");
startActivity(openStartingPoint);

谢谢

试试这个，

Intent intent = new Intent(MainActivity.this, Second.class);
startActivity(intent);
