I have to make an application which shows the contact no of the SIM card that is being used in the cell. For that I need to use TelephonyManager class. Can I get details on its usage?

推荐答案

您可以使用 TelephonyManager 为此:

You can use the TelephonyManager to do this:

TelephonyManager tm = (TelephonyManager)getSystemService(TELEPHONY_SERVICE); 
String number = tm.getLine1Number();

getLine1Number()的文档表示如果数字不可用"，则此方法将返回null，但没有说明数字何时不可用.

The documentation for getLine1Number() says this method will return null if the number is "unavailable", but it does not say when the number might be unavailable.

您需要授予您的应用程序通过在清单中添加以下内容来进行此查询:

You'll need to give your application permission to make this query by adding the following to your Manifest:

<uses-permission android:name="android.permission.READ_PHONE_STATE"/>

(您不应该使用TelephonyManager.getDefault()作为

(You shouldn't use TelephonyManager.getDefault() to get the TelephonyManager as that is a private undocumented API call and may change in future.)
