當使用者在系統相簿，點擊分享時，能通過我們自己的app，分享該圖片。

1.註冊

主要是在AndroidManifest.xml中，對activity註冊Intent-filter，如：

<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></activity>

2.處理：

在Activity中，擷取Intent中的文本和圖片等。

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    }    ...}void handleSendText(Intent intent) {    String sharedText = intent.getStringExtra(Intent.EXTRA_TEXT);    if (sharedText != null) {        // Update UI to reflect text being shared    }}void handleSendImage(Intent intent) {    Uri imageUri = (Uri) intent.getParcelableExtra(Intent.EXTRA_STREAM);    if (imageUri != null) {        // Update UI to reflect image being shared    }}void handleSendMultipleImages(Intent intent) {    ArrayList<Uri> imageUris = intent.getParcelableArrayListExtra(Intent.EXTRA_STREAM);    if (imageUris != null) {        // Update UI to reflect multiple images being shared    }}
