You can use Intent.ACTION_DIAL instead of Intent.ACTION_CALL . 您可以使用Intent.ACTION_DIAL代替Intent.ACTION_CALL 。 This shows the dialer with the number already entered, but allows the user to decide whether to actually make the call or not. 这将显示已输入号码的拨号程序，但允许用户决定是否实际拨打电话。 ACTION_DIAL does not require the CALL_PHONE permission. ACTION_DIAL不需要CALL_PHONE权限。

您也可以使用此：
String uri = "tel:" + posted_by.replaceAll("[^0-9|\\+]", "");

In Android for certain functionalities you need to add the permission to the Manifest file. 在Android中，对于某些功能，您需要将权限添加到清单文件中。
- Go to the Projects AndroidManifest.xml 转到项目AndroidManifest.xml
- Click on the Permissions Tab 单击权限选项卡
- Click on Add 点击添加
- Select Uses Permission 选择使用权限
- See the snapshot below 见下面的快照
6.Save the manifest file and then run your project. 6.保存清单文件，然后运行您的项目。 Your project now should run as expected. 您的项目现在应该可以按预期运行。
