添加或删除createChooser选项 [英] add or remove options from createChooser

问题描述

String message = "Text I want to share";
Intent share = new Intent(Intent.ACTION_SEND);
share.setType("text/plain");
share.putExtra(Intent.EXTRA_TEXT, message);
startActivity(Intent.createChooser(share,"Share on"));

现在它显示像默认选项：蓝牙，电子邮件，Facebook和Gmail中，LinkedIn的消息，分享通过条形码code

或者是这些已安装的应用程序？

or are these the installed apps?

我想是知道的，我怎么可以从这个名单中删除一些。像我想删除分享通过条形码code 。

what i want is to know, how i can remove few from this list. like i want to remove Share Via Barcode.

和添加其他什么东西？

推荐答案

使用低于code到一个新的项目添加到选择屏幕。

Use below code to add a new Item to the Chooser Screen.

Intent share = new Intent(Intent.ACTION_SEND);
share.setType("text/plain");       
share.putExtra(Intent.EXTRA_TEXT, message);

Intent addIntent = ;//whatever you want

Intent chooser = new Intent(Intent.ACTION_CHOOSER);
chooser.putExtra(Intent.EXTRA_INTENT, share );      
chooser.putExtra(Intent.EXTRA_TITLE, "title");

Intent[] intentArray =  {addIntent }; 
chooser.putExtra(Intent.EXTRA_INITIAL_INTENTS, intentArray);
startActivity(chooser);

不过，除去特定项目是不可能的。所以，你可以解决使用意图<一href="http://developer.android.com/reference/android/content/pm/PackageManager.html#resolveActivity%28android.content.Intent,%20int%29">Packagemanager.resolveActivity并创建自己的自定义列表视图

But removing specific items is not possible. So you could resolve the intent using Packagemanager.resolveActivity and create your own custom list view
