直接上代码:

/*** 指定sim卡拨打电话** @param phoneNumber* @param slotId      0:卡1  1:卡2*/public void callPhone(String phoneNumber, int slotId) {LogUtil.d(TAG, "call phone : phoneNumber=" + phoneNumber + ", slotId=" + slotId);PhoneAccountHandle phoneAccountHandle = getPhoneAccountHandle(slotId);Intent intent = new Intent(Intent.ACTION_CALL, Uri.parse("tel:" + phoneNumber));intent.putExtra(TelecomManager.EXTRA_PHONE_ACCOUNT_HANDLE, phoneAccountHandle);intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);mContext.startActivity(intent);}

/**这一块首先获取手机中所有sim卡 PhoneAccountHandle 每一个 PhoneAccountHandle 表示一个sim卡, 然后根据 slotId 判断所指定的sim卡并返回此 PhoneAccountHandle (这里5.1 和 6.0需要区分对待)
*/
@Target Api(Build.VERSION_CODES.M)private PhoneAccountHandle getPhoneAccountHandle(int slotId) {TelecomManager tm = (TelecomManager) mContext.getSystemService(Context.TELECOM_SERVICE);//PhoneAccountHandle api>5.1if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP_MR1) {List<PhoneAccountHandle> handles = (List<PhoneAccountHandle>) ReflectUtil.invokeMethod(tm, "getCallCapablePhoneAccounts");SubscriptionManager sm = SubscriptionManager.from(mContext);if (handles != null) {for (PhoneAccountHandle handle : handles) {SubscriptionInfo info = sm.getActiveSubscriptionInfoForSimSlotIndex(slotId);if (info != null) {if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {if (TextUtils.equals(info.getIccId(), handle.getId())) {LogUtil.d(TAG, "getPhoneAccountHandle for slot" + slotId + " " + handle);return handle;}} else if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP_MR1) {if (TextUtils.equals(info.getSubscriptionId() + "", handle.getId())) {LogUtil.d(TAG, "getPhoneAccountHandle for slot" + slotId + " " + handle);return handle;}}}}}}return null;}

以上就是指定sim卡拨打的全部代码, 不擅长写博客, 希望对有需要的童鞋有所帮助.
