//第一步 先加入權限，在AndroidManifest.xml里加入：

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

//動態權限申請：

//權限初始化 private int READ_PHONE_STATE = 1; private String[] CALLS_STATE = {Manifest.permission.READ_PHONE_STATE,Manifest.permission.WRITE_EXTERNAL_STORAGE,Manifest.permission.RECORD_AUDIO, }; /** 方法名：verifyStoragePermissions(Activity activity)* 功 能：6.0動態權限* 參 數：Activity activity* 返回值：無*/ public void verifyStoragePermissions(Activity activity) {int permission = ActivityCompat.checkSelfPermission(activity, Manifest.permission.READ_PHONE_STATE);if (permission != PackageManager.PERMISSION_GRANTED) {ActivityCompat.requestPermissions(activity, CALLS_STATE, READ_PHONE_STATE);} }

//在Activity里調用：

verifyStoragePermissions(this);//調用請求6.0權限的方法

//好了 權限申請完成后開始獲取SIM卡槽數量，可用SIM卡數量：

@TargetApi(Build.VERSION_CODES.M) @RequiresApi(api = Build.VERSION_CODES.LOLLIPOP_MR1) private void JudgeSIM() {TelephonyManager tm = (TelephonyManager)getContext().getSystemService(TELEPHONY_SERVICE);int phoneCount = tm.getPhoneCount(); //獲取當前SIM卡槽數量//獲取當前SIM卡數量int activeSubscriptionInfoCount = SubscriptionManager.from(getContext()).getActiveSubscriptionInfoCount();Toast.makeText(getContext(), "卡槽數量："+phoneCount, Toast.LENGTH_SHORT).show();Toast.makeText(getContext(), "當前SIM卡數量："+activeSubscriptionInfoCount, Toast.LENGTH_SHORT).show(); }
