本博客讲述的是:
自定义应用分享文本,图片,多个图片到本身的具体实现(本文中的ShareActionProvider未使用成功,所以已经注释掉了)

3.若是想要实现分享列表中有自建应用,那么~

(1)首先更新AndroidManifest.xml在<activity ***></activity>中加上:<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>(2)其实加了上面一段后,其实已经可以做到分享到本应用,但为了让表现直观以及了解简单的分享处理,增加如下代码:a.MainActivity.java中:public void init(){        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        }    }    void handleSendText(Intent intent) {        String sharedText = intent.getStringExtra(Intent.EXTRA_TEXT);        String sharedTitle = intent.getStringExtra(Intent.EXTRA_TITLE);        if (sharedText != null) {            // Update UI to reflect text being shared            Toast.makeText(MainActivity.this,sharedText,Toast.LENGTH_SHORT).show();        }    }    void handleSendImage(Intent intent) {        Uri imageUri = (Uri) intent.getParcelableExtra(Intent.EXTRA_STREAM);        if (imageUri != null) {            //在处理二进制数据时，应当在一另外一个线程中去处理            // Update UI to reflect image being shared            Toast.makeText(MainActivity.this,imageUri.toString(),Toast.LENGTH_SHORT).show();        }    }    void handleSendMultipleImages(Intent intent) {        ArrayList<Uri> imageUris = intent.getParcelableArrayListExtra(Intent.EXTRA_STREAM);        if (imageUris != null) {            //在处理二进制数据时，应当在一另外一个线程中去处理            // Update UI to reflect multiple images being shared            Toast.makeText(MainActivity.this,imageUris.get(0).toString(),Toast.LENGTH_SHORT).show();        }    }    b.MainActivity的onCreate()方法中增加init();
