如何获得手机服务信号强度的Andr​​oid？ [英] How to get cell service signal strength in Android?

问题描述

我想写一个非常简单的Andr​​oid应用程序，检查当前单元格的信号强度。到目前为止，我只发现了一些所谓的 getNeighboringCellInfo（），但我真的不知道，如果它包括当前单元格。

如何获取当前单元格的信号强度在Android的？

确实 getNeighborCellInfo（）获取当前单元格？它似乎并不像它的基础上，我已经能够得到它的结果。这是我目前的code：

 名单，其中，NeighboringCellInfo＆GT; N = tm.getNeighboringCellInfo（）;

//构造字符串
字符串s =;
INT RSS = 0;
INT CID = 0;
对于（NeighboringCellInfo NCI：N）
{
    CID = nci.getCid（）;
    RSS = -113 + 2 * nci.getRssi（）;
    S + =小区ID：+ Integer.toString（CID）+信号功率（dBm）：+
            Integer.toString（RSS）+\ N的;
}

mainText.setText（多个）;
 

解决方案

创建一个<一个href="http://developer.android.com/reference/android/telephony/PhoneStateListener.html">PhoneStateListener并处理onSignalStrengthChanged回调。当你的应用程序初始化，它应该给你一个初始通知。这是在1.x的在2.x中，有一个开放的问题这一点。

I am trying to write a very simple Android application that checks the signal strength of the current cell. So far, I have only found something called getNeighboringCellInfo(), but I'm not really sure if that includes the current cell.

How do I get the CURRENT cell signal strength in Android?

Does getNeighborCellInfo() get the current cell? It doesn't seem like it based on the results that I have been able to get with it. Here's my current code:

List<NeighboringCellInfo> n = tm.getNeighboringCellInfo();

//Construct the string
String s = "";
int rss = 0;
int cid = 0;
for (NeighboringCellInfo nci : n)
{
    cid = nci.getCid();
    rss = -113 + 2*nci.getRssi();
    s += "Cell ID: " + Integer.toString(cid) + "     Signal Power (dBm): " + 
            Integer.toString(rss) + "\n";
}

mainText.setText(s);

解决方案

create a PhoneStateListener and handle the onSignalStrengthChanged callback. When your app is initialized, it should give you an initial notification. This is in 1.x. in 2.x, there's an open issue about this.
