编辑您的 AndroidManifest.xml

Question

在NativeScript的当前状态下是否有可能创建一个在Android上侦听共享意图的应用程序？

我想要实现的是例如在Android上的网络浏览器中打开网站，点击共享并在共享目标列表中查看我的NativeScript应用。

我在原生Android应用上完成了此操作但无法在NativeScript应用中使用它。我已经搞乱了AndroidManifest.xml来添加

<action android:name="android.intent.action.SEND"></action>
<category android:name="android.intent.category.DEFAULT"></category>

进入intent-filter但这没有帮助。我的应用未显示在共享目标列表中。

Answer 1

除了必须在AppManifest.xml中添加的intent-filter之外确保重建您的应用程序（livesync选项可能无法反映AppManifest.xml中的更改）

以下是基本共享的NativeScript实现

var app = require("application");

function onShare() {

    var sharingIntent = new android.content.Intent(android.content.Intent.ACTION_SEND);
    sharingIntent.setType("text/plain");
    var shareBody = "Here is the share content body";

    sharingIntent.addFlags(android.content.Intent.FLAG_ACTIVITY_CLEAR_WHEN_TASK_RESET);
    sharingIntent.addFlags(android.content.Intent.FLAG_ACTIVITY_NEW_TASK | android.content.Intent.FLAG_ACTIVITY_MULTIPLE_TASK);

    sharingIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, "Subject Here");
    sharingIntent.putExtra(android.content.Intent.EXTRA_TEXT, shareBody);

    app.android.context.startActivity(sharingIntent);
}
exports.onShare = onShare;

Answer 2

NativeScript应该支持这种情况。以下是我在默认引导应用程序的app/App_resources/Android中的AndroidManifest：

<activity
        android:name="com.tns.NativeScriptActivity"
        android:label="@string/title_activity_kimera"
        android:configChanges="keyboardHidden|orientation|screenSize">

        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
        <intent-filter> 
            <action android:name="android.intent.action.SEND" />
            <category android:name="android.intent.category.DEFAULT" />
            <data android:mimeType="text/plain" />
       </intent-filter>
</activity>

编辑：将意图发送到我的任何其他应用程序的非常简单的实现：

FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);
        fab.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                Intent sendIntent = new Intent(Intent.ACTION_SEND);
                sendIntent.setType("text/plain");
                sendIntent.putExtra("string", "the data Im sending you");

                Intent chooser = Intent.createChooser(sendIntent, "Share with ");

                if (sendIntent.resolveActivity(getPackageManager()) != null) {
                    startActivity(chooser);
                }
            }
        });

首先在app / App_Resources / AndroidManifest.xml中更新AndroidManifest.xml

添加以下意图过滤器，如下所示

<application        android:name="com.tns.NativeScriptApplication"      android:allowBackup="true"      android:icon="@drawable/icon"       android:label="@string/app_name"
                android:theme="@style/AppTheme">        <activity           android:name="com.tns.NativeScriptActivity"
                        android:label="@string/title_activity_kimera"           android:configChanges="keyboardHidden|orientation|screenSize">

                        <intent-filter>
                <action android:name="android.intent.action.MAIN" />                                
                <category android:name="android.intent.category.LAUNCHER" />            </intent-filter>                        
                        <intent-filter>
                                <action android:name="android.intent.action.SEND" />
                                <category android:name="android.intent.category.DEFAULT" />
                                <category android:name="android.intent.category.APP_BROWSER" />
                                <data android:mimeType="text/plain" /> 
                                <data android:mimeType="image/*" />
                        </intent-filter>
                        <intent-filter>
                            <action android:name="android.intent.action.SEND_MULTIPLE" />
                            <category android:name="android.intent.category.DEFAULT" />
                            <category android:name="android.intent.category.APP_BROWSER" />
                            <data android:mimeType="image/*" />
                        </intent-filter>
                                </activity>         <activity android:name="com.tns.ErrorReportActivity"/>  </application>

然后在app.js中添加以下代码行

application.android.on(application.AndroidApplication.activityResumedEvent, function (args) {
        console.log("Event: " + args.eventName + ", Activity: " + args.activity);
        var a = args.activity;
        try {
            var Intent_1 = android.content.Intent;
            var actionSend = Intent_1.ACTION_SEND;
            var actionSendMultiple = Intent_1.ACTION_SEND_MULTIPLE;
            var argIntent = a.getIntent();
            var argIntentAction = argIntent.getAction();
            var argIntentType = argIntent.getType();
            console.log(" ~~~~ Intent is ~~~~ :" + new String(argIntent.getAction()).valueOf());
            String.prototype.startsWith = function (str) {
                return this.substring(0, str.length) === str;
            };
            if (new String(argIntentAction).valueOf() === new String(Intent_1.ACTION_SEND).valueOf()) {
                if (new String(argIntentType).valueOf() === new String("text/plain").valueOf()) {
                    console.dump(cbParseTextAndUrl(argIntent));
                }
                else if (argIntentType.startsWith("image/")) {
                    console.log(cbParseImageUrl(argIntent));
                }
            }
            else if (new String(argIntentAction).valueOf() === new String(Intent_1.ACTION_SEND_MULTIPLE).valueOf()) {
                if (argIntentType.startsWith("image/")) {
                    var Uri = cbParseMultipleImageUrl(argIntent);
                    if (Uri !== null) {
                        var Uris = JSON.parse(Uri);
                        console.log(Uris);
                    }
                }
            }
            function cbParseTextAndUrl(argIntent) {
                var Patterns = android.util.Patterns;
                //let Matcher = java.util.regex.Matcher;
                var ListUrl = [];
                var text = argIntent.getStringExtra(Intent_1.EXTRA_TEXT);
                if (new String().valueOf() !== "null") {
                    var Matcher = Patterns.WEB_URL.matcher(text);
                    while (Matcher.find()) {
                        var url = Matcher.group();
                        ListUrl.push(url);
                    }
                    return { "text": text, "listUrl": ListUrl };
                }
            }
            function cbParseImageUrl(argIntent) {
                var imageUri = argIntent.getParcelableExtra(Intent_1.EXTRA_STREAM);
                if (imageUri != null) {
                    // Update UI to reflect image being shared
                    return imageUri;
                }
            }
            function cbParseMultipleImageUrl(argIntent) {
                var imageUris = argIntent.getParcelableArrayListExtra(Intent_1.EXTRA_STREAM);
                if (imageUris != null) {
                    // Update UI to reflect image being shared
                    return JSON.stringify(imageUris.toString());
                }
            }
        }
        catch (e) {
            console.log(e);
        }
    });

现在，您可以将第三方应用中的内容分享到您的应用。

我自己一直在寻找解决方案，发现这里所有其他答案非常有帮助。

但是，我对 NativeScript 还是一个菜鸟（仅两天），实际上无法获得在哪里以及如何实现所有代码位一起工作。

通过使用此处的答案，我可以继续搜索并找到完成的GITHUB示例：NickIliev/nativescript-receiving-shared-content

对于其他希望完成示例的新生（或新生），请访问存储库并浏览/demo/app/目录中的代码。这对我很有帮助，希望对您有帮助。

如果有人正在寻找最新的 NS7 和 NS8 兼容版本，这对我和 Android 都有效。这是在 NS8 的抽屉模板应用程序上测试的。 Javascript 部分用于 home-page.js ，只需将其内容替换为下面的代码即可。

NS7 和 NS8 的进口不同，这让人们感到困惑。
