Question

我正在处理一个Text base应用程序，该应用程序可以通过分享分享中的其他应用程序的某些部分，并接受来自其他应用程序的共享文本。当我想分享我的数据时，我的应用程序通过屏幕出现在共享中，如何从这个屏幕中删除我的应用程序，虽然我想在其他应用程序共享一些文本时，在＆＃34;分享通过＆＃34;屏幕，我的应用程序应放在那里。这是我的代码：

Intent sharingIntent = new Intent(android.content.Intent.ACTION_SEND); sharingIntent.setType("text/plain"); String shareBody = "Here is the share content"; sharingIntent.putExtra(android.content.Intent.EXTRA_TEXT, shareBody); startActivity(Intent.createChooser(sharingIntent, "Share via"));

还有：

<activity android:name=".TestActivity" android:label="@string/app_name"> <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>

感谢。

找到一种方法创建一个阻止某些应用程序显示的CustomChooser

只需将您的包名称传递给字符串数组黑名单，您的应用就会被丢弃。

String[] nameOfAppsToShareWith = new String[] { "facebook", "twitter", "gmail" };
String[] blacklist = new String[]{"com.any.package", "net.other.package"};
// your share intent
Intent intent = new Intent(Intent.ACTION_SEND);
intent.setType("text/plain");
intent.putExtra(Intent.EXTRA_TEXT, "some text");
intent.putExtra(android.content.Intent.EXTRA_SUBJECT, "a subject");
// ... anything else you want to add invoke custom chooser
startActivity(generateCustomChooserIntent(intent, blacklist));

private Intent generateCustomChooserIntent(Intent prototype,
            String[] forbiddenChoices)
    {
        List<Intent> targetedShareIntents = new ArrayList<Intent>();
        List<HashMap<String, String>> intentMetaInfo = new ArrayList<HashMap<String, String>>();
        Intent chooserIntent;

        Intent dummy = new Intent(prototype.getAction());
        dummy.setType(prototype.getType());
        List<ResolveInfo> resInfo = getPackageManager().queryIntentActivities(dummy,0);

        if (!resInfo.isEmpty())
        {
            for (ResolveInfo resolveInfo : resInfo)
            {
                if (resolveInfo.activityInfo == null
                        || Arrays.asList(forbiddenChoices).contains(
                                resolveInfo.activityInfo.packageName))
                    continue;
                //Get all the posible sharers
                HashMap<String, String> info = new HashMap<String, String>();
                info.put("packageName", resolveInfo.activityInfo.packageName);
                info.put("className", resolveInfo.activityInfo.name);
                String appName = String.valueOf(resolveInfo.activityInfo
                        .loadLabel(getPackageManager()));
                info.put("simpleName", appName);
                //Add only what we want
                if (Arrays.asList(nameOfAppsToShareWith).contains(
                        appName.toLowerCase()))
                {
                    intentMetaInfo.add(info);
                }
            }

            if (!intentMetaInfo.isEmpty())
            {
                // sorting for nice readability
                Collections.sort(intentMetaInfo,
                        new Comparator<HashMap<String, String>>()
                        {
                            @Override public int compare(
                                    HashMap<String, String> map,
                                    HashMap<String, String> map2)
                            {
                                return map.get("simpleName").compareTo(
                                        map2.get("simpleName"));
                            }
                        });

                // create the custom intent list
                for (HashMap<String, String> metaInfo : intentMetaInfo)
                {
                    Intent targetedShareIntent = (Intent) prototype.clone();
                    targetedShareIntent.setPackage(metaInfo.get("packageName"));
                    targetedShareIntent.setClassName(
                            metaInfo.get("packageName"),
                            metaInfo.get("className"));
                    targetedShareIntents.add(targetedShareIntent);
                }
                String shareVia = getString(R.string.offer_share_via);
                String shareTitle = shareVia.substring(0, 1).toUpperCase()
                        + shareVia.substring(1);
                chooserIntent = Intent.createChooser(targetedShareIntents
                        .remove(targetedShareIntents.size() - 1), shareTitle);
                chooserIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS,
                        targetedShareIntents.toArray(new Parcelable[] {}));
                return chooserIntent;
            }
        }

        return Intent.createChooser(prototype,
                getString(R.string.offer_share_via));
    }

我认为您正在寻找从其他应用接收简单数据。如果是，那么应该对不同类型的数据使用android：mimeType条件。将以下代码放在您的清单活动中。

<activity android:name=".ui.MyActivity" >
<intent-filter>
    <action android:name="android.intent.action.SEND" />
    <category android:name="android.intent.category.DEFAULT" />
    <data android:mimeType="image/*" />
</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>
<intent-filter>
    <action android:name="android.intent.action.SEND_MULTIPLE" />
    <category android:name="android.intent.category.DEFAULT" />
    <data android:mimeType="image/*" />
</intent-filter>

处理传入内容

void onCreate (Bundle savedInstanceState) {
...
// Get intent, action and MIME type
Intent intent = getIntent();
String action = intent.getAction();
String type = intent.getType();

if (Intent.ACTION_SEND.equals(action) && type != null) {
    if ("text/plain".equals(type)) {
        handleSendText(intent); // Handle text being sent
    } else if (type.startsWith("image/")) {
        handleSendImage(intent); // Handle single image being sent
    }
} else if (Intent.ACTION_SEND_MULTIPLE.equals(action) && type != null) {
    if (type.startsWith("image/")) {
        handleSendMultipleImages(intent); // Handle multiple images being sent
    }
} else {
    // Handle other intents, such as being started from the home screen
}
...

}
