如何从3克检测网络类型转换成H + Android上 [英] how to detect network type change from 3g to H+ on Android

问题描述

与connectivitymanager和广播接收器，我能够得到连接和断开事件解释埃里克这里

with connectivitymanager and broadcast receiver I'm able to get connection and disconnection events as explained Eric's post here

我想知道的是当网络连接类型的变化。
例如：3G到H +，反之亦然。我看到里面有的onReceive（..）时，这个变化发生的...

What I would like to know is the change in type while network is being connected. Ex: 3G to H+ and vice versa.. I see there are no events inside OnReceive(..) when this change happens...

用户案例清晰：
第一步：3G连接被启用，以广播接收的事件（BCR）和加工
第二步：发起呼叫，在从3G到H +连接的变化，但在BCR任何情况

User case for clarity: step1: 3G connection is enabled, events received in broadcast(BCR) and processed step2: start a call, changes in connection from 3G to h+ but no event in BCR.

预计产量：预计BCR的事件时有从3G切换到H +或边缘...

expected output: expect an event in BCR when there is change from 3G to h+ or Edge...

推荐答案

在这里，switch语句，你可以做一定的TAKS。一个线程可以拨打以下code和照看网络。

Here, on switch statement you can do certain taks. A Thread can call the following code and keep an eye on network.

获取网络类型

TelephonyManager teleMan =   
            (TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE); 
int networkType = teleMan.getNetworkType(); 

switch (networkType) 
{ 
case 7: 
    textV1.setText("1xRTT"); 
    break;       
case 4: 
    textV1.setText("CDMA"); 
    break;       
case 2: 
    textV1.setText("EDGE"); 
    break;   
case 14: 
    textV1.setText("eHRPD"); 
    break;       
case 5: 
    textV1.setText("EVDO rev. 0"); 
    break;   
case 6: 
    textV1.setText("EVDO rev. A"); 
    break;   
case 12: 
    textV1.setText("EVDO rev. B"); 
    break;   
case 1: 
    textV1.setText("GPRS"); 
    break;       
case 8: 
    textV1.setText("HSDPA"); 
    break;       
case 10: 
    textV1.setText("HSPA"); 
    break;           
case 15: 
    textV1.setText("HSPA+"); 
    break;           
case 9: 
    textV1.setText("HSUPA"); 
    break;           
case 11: 
    textV1.setText("iDen"); 
    break; 
case 13: 
    textV1.setText("LTE"); 
    break; 
case 3: 
    textV1.setText("UMTS"); 
    break;           
case 0: 
    textV1.setText("Unknown"); 
    break; 
}
