Android Share App Data (ACTION_SEND)

Android使用 ACTION_SEND 事件來發(fā)送數(shù)據(jù)，其屬于 android.content.Intent 類，可以將數(shù)據(jù)從一個(gè)活動(dòng)發(fā)送到另一個(gè)活動(dòng)以及從當(dāng)前活動(dòng)發(fā)送到應(yīng)用程序外部。愛掏網(wǎng) - it200.comIntent類需要指定要共享的數(shù)據(jù)及其類型。愛掏網(wǎng) - it200.com

通常情況下，ACTION_SEND操作會(huì)發(fā)送內(nèi)置瀏覽器應(yīng)用程序的URL。愛掏網(wǎng) - it200.com在共享數(shù)據(jù)時(shí)，Intent調(diào)用createChooser()方法，該方法接收Intent對象并指定選擇器對話框的標(biāo)題。愛掏網(wǎng) - it200.com Intent.createChooser()方法用于顯示選擇器。愛掏網(wǎng) - it200.com

ACTION_SEND示例

在此示例中，我們將共享純文本，即瀏覽器的URL鏈接。愛掏網(wǎng) - it200.com
