Question

我可以在一个活动中获取bts信息，但是当在这个代码的OnRecive中使用该代码时它不起作用，为什么这个代码无法获得bts塔？

package com.example.testneighbore;

import android.content.BroadcastReceiver;
        import android.content.Context;
        import android.content.Intent;
        import android.os.Bundle;
        import android.telephony.NeighboringCellInfo;
        import android.telephony.TelephonyManager;
        import android.widget.Toast;

        import java.util.List;


public class SMS extends BroadcastReceiver
{
    @Override
    public void onReceive(Context context, Intent intent)
    {

        Bundle bundle = intent.getExtras();
        if (bundle != null)
        {
            Toast.makeText(context, " START ", Toast.LENGTH_LONG).show();
            TelephonyManager telephonyManager = (TelephonyManager) context.getSystemService(context.TELEPHONY_SERVICE);
            List<NeighboringCellInfo> NeighboringList = telephonyManager.getNeighboringCellInfo();

            String retStr="";
            for (int i = 0; i < NeighboringList.size(); i++) {

                int cid = NeighboringList.get(i).getCid();
                int lac = NeighboringList.get(i).getLac();
                retStr += "&" + cid + "," + lac + ",";

            }
            Toast.makeText(context,"Print: "+ retStr, Toast.LENGTH_LONG).show();
            Toast.makeText(context, " END ", Toast.LENGTH_LONG).show();

        }
    }


}

我的AndroidManifest.xml是：

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.testneighbore"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk
        android:minSdkVersion="8"
        android:targetSdkVersion="19" />

    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <activity
            android:name="com.example.testneighbore.MainActivity"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <receiver android:name=".SMS">
            <intent-filter android:priority="999">
                <action android:name="android.provider.Telephony.SMS_RECEIVED" />
            </intent-filter>
        </receiver>
    </application>
    <uses-permission android:name="android.permission.SEND_SMS"/>
    <uses-permission android:name="android.permission.RECEIVE_SMS"/>
    <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="com.google.android.providers.gsf.permission.READ_GSERVICES" />
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
    <uses-permission android:name="android.permission.ACCESS_COARSE_UPDATES"/>
</manifest>

我认为我的主要问题是Context，但我不确定。

您的问题与上下文有关，因为上下文涉及接收短信。要解决这个问题，你必须创建线程并获取bts信息。最好在~20秒内延迟调用你的线程。你可以在OnRecieve（）

中使用这样的东西

 Handler handler = new Handler();
 handler.postDelayed(new Runnable() {
      public void run() {
                       // get info 

      }
 }, 20000);

收到短信后，获取所有BTS塔
