Android TelephonyManager (电话管理器)
TelephonyManager 用于管理手机通话状态，获取电话信息(设备信息、sim卡信息以及 网络信息)，侦听电话状态(呼叫状态服务状态、信号强度状态等)以及可以调用电话拨号器拨打电话
获得 TelephonyManager 的服务对象
TelephonyManager tm = (TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE);
调用拨号器拨打电话号码
Uri uri=Uri.parse("tel:"+电话号码); Intent intent=new Intent(Intent.ACTION_DIAL,uri); startActivity(intent);
获取 Sim 卡信息与网络信息

添加授权页
授权页, 首先使用系统默认的授权页, 当用户拒绝时, 指导用户手动设置, 当用户再次操作失败后, 返回继续提示
用户手动退出授权页时, 给使用页发送授权失败的通知
我们可以保存这个授权页并将其在多个应用中复用

其它信息
如果想获取网络制式，而非普通的 2G,3G,4G 这样，可以调用 getNetworkClass() 方法
/** * Return general class of network type, such as "3G" or "4G". In cases * where classification is contentious, this method is conservative. * * @hide */ public static int getNetworkClass(int networkType) { switch (networkType) { case NETWORK_TYPE_GPRS: case NETWORK_TYPE_GSM: case NETWORK_TYPE_EDGE: case NETWORK_TYPE_CDMA: case NETWORK_TYPE_1xRTT: case NETWORK_TYPE_IDEN: return NETWORK_CLASS_2_G; case NETWORK_TYPE_UMTS: case NETWORK_TYPE_EVDO_0: case NETWORK_TYPE_EVDO_A: case NETWORK_TYPE_HSDPA: case NETWORK_TYPE_HSUPA: case NETWORK_TYPE_HSPA: case NETWORK_TYPE_EVDO_B: case NETWORK_TYPE_EHRPD: case NETWORK_TYPE_HSPAP: case NETWORK_TYPE_TD_SCDMA: return NETWORK_CLASS_3_G; case NETWORK_TYPE_LTE: case NETWORK_TYPE_IWLAN: case NETWORK_TYPE_LTE_CA: return NETWORK_CLASS_4_G; default: return NETWORK_CLASS_UNKNOWN; } }
我们可以根据这个 networkType 的值，判断不同的网络制式，比如，如果 networkType == 1
那个是 GPRS 这种制式的，而这个networkType的值可以通过
/** * Returns a string representation of the radio technology (network type) * currently in use on the device. * @return the name of the radio technology * * @hide pending API council review */ public String getNetworkTypeName() { return getNetworkTypeName(getNetworkType()); } /** * Returns a string representation of the radio technology (network type) * currently in use on the device. * @param subId for which network type is returned * @return the name of the radio technology * */ /** {@hide} */ public static String getNetworkTypeName(int type) { switch (type) { case NETWORK_TYPE_GPRS: return "GPRS"; case NETWORK_TYPE_EDGE: return "EDGE"; case NETWORK_TYPE_UMTS: return "UMTS"; case NETWORK_TYPE_HSDPA: return "HSDPA"; case NETWORK_TYPE_HSUPA: return "HSUPA"; case NETWORK_TYPE_HSPA: return "HSPA"; case NETWORK_TYPE_CDMA: return "CDMA"; case NETWORK_TYPE_EVDO_0: return "CDMA - EvDo rev. 0"; case NETWORK_TYPE_EVDO_A: return "CDMA - EvDo rev. A"; case NETWORK_TYPE_EVDO_B: return "CDMA - EvDo rev. B"; case NETWORK_TYPE_1xRTT: return "CDMA - 1xRTT"; case NETWORK_TYPE_LTE: return "LTE"; case NETWORK_TYPE_EHRPD: return "CDMA - eHRPD"; case NETWORK_TYPE_IDEN: return "iDEN"; case NETWORK_TYPE_HSPAP: return "HSPA+"; case NETWORK_TYPE_GSM: return "GSM"; case NETWORK_TYPE_TD_SCDMA: return "TD_SCDMA"; case NETWORK_TYPE_IWLAN: return "IWLAN"; case NETWORK_TYPE_LTE_CA: return "LTE_CA"; default: return "UNKNOWN"; } }
即这个 getNetworkType() 方法获得！好了，就这么简单，可以像上面列好一个数组然后根据
不同的下标显示不同的值！
Sim 卡状态的，字符串数组中的值
/** * Returns a constant indicating the state of the default SIM card. * * @see #SIM_STATE_UNKNOWN * @see #SIM_STATE_ABSENT * @see #SIM_STATE_PIN_REQUIRED * @see #SIM_STATE_PUK_REQUIRED * @see #SIM_STATE_NETWORK_LOCKED * @see #SIM_STATE_READY * @see #SIM_STATE_NOT_READY * @see #SIM_STATE_PERM_DISABLED * @see #SIM_STATE_CARD_IO_ERROR * @see #SIM_STATE_CARD_RESTRICTED */ public int getSimState() { int slotIndex = getSlotIndex(); // slotIndex may be invalid due to sim being absent. In that case query all slots to get // sim state if (slotIndex < 0) { // query for all slots and return absent if all sim states are absent, otherwise // return unknown for (int i = 0; i < getPhoneCount(); i++) { int simState = getSimState(i); if (simState != SIM_STATE_ABSENT) { Rlog.d(TAG, "getSimState: default sim:" + slotIndex + ", sim state for " + "slotIndex=" + i + " is " + simState + ", return state as unknown"); return SIM_STATE_UNKNOWN; } } Rlog.d(TAG, "getSimState: default sim:" + slotIndex + ", all SIMs absent, return " + "state as absent"); return SIM_STATE_ABSENT; } return getSimState(slotIndex); }
