Question

在我的应用程序中，我想获取用户的SIM号码（如果有的话），我尝试了以下代码，但它返回＆＃34;＆＃34;

const format = 'YYYY-MM-DD hh:mm:ss a';

所需权限

TelephonyManager tMgr = 
(TelephonyManager)mAppContext.getSystemService(Context.TELEPHONY_SERVICE);
String mPhoneNumber = tMgr.getLine1Number();

我到处寻找一种方法来获取用户的SIM卡号，但对我来说没什么用。有些人说可能是用户的SIM卡提供商对此功能有限制，但是我使用imo应用程序获取我的SIM号并在应用程序中显示，所以我在同一个手机上尝试了不同的方法，但没有任何作用，如果有人知道工作方法，请告诉我

Answer 1

第1步：在AndroidManifest.xml中添加必需的权限

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

注意：对于6.0（棉花糖）及以上设备使用Run Rime Permissions

第2步：

TelephonyManager telephonyManager = (TelephonyManager)this.getSystemService(Context.TELEPHONY_SERVICE);

    String sim1= telephonyManager.getLine1Number();  

    String sim2= telephonyManager.getLine2Number();

检查this以获取更多信息

首先，我建议你应该使用共享偏好，只需存储它并在你的应用程序中随时随地使用它。这是我猜的最简单的方法。

或

尝试登记

电话 - ＆GT;设置 - ＆gt;关于 - ＆gt;

电话身份，如果你可以在那里查看号码，那么你可以获得号码。但如果您无法在设置中查看电话号码，那么您将无法通过此代码获取。

在Manifest中启用权限，获取您的SMI号码和Imei号码

Manifest.Java

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

MainActivity.Java

  public class MainActivity extends AppCompatActivity {
     Activity mActivity; 
     String mStatus;
    private TextView mSmiTxt;

            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_main);
            mActivity = MainActivity.this;
        mSmiTxt = (TextView) this.findViewById(R.id.smitxt);
mStatus=loadSMI1();
 mSmiTxt.setText(mStatus);

            //Get IMEI Number of Phone  //////////////// for this example i only need the IMEI
            String IMEINumber = tm.getDeviceId();
            return IMEINumber;
        }
     private void alertAlert(String msg) {

                            // do somthing here
                        }

     public String loadSMI1() {
            TelephonyManager tm = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
            String sim1 = tm.getLine1Number();
            return sim1;
        }


    }

如果SMI编号返回null，请从whatsapp

获取

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


AccountManager am = AccountManager.get(this);
Account[] accounts = am.getAccounts();

ArrayList<String> googleAccounts = new ArrayList<String>();
for (Account ac : accounts) {
    String acname = ac.name;
    String actype = ac.type;
    // Take your time to look at all available accounts
    System.out.println("Accounts : " + acname + ", " + actype);
}
if(actype.equals("com.whatsapp")){
    String phoneNumber = ac.name;
}
