Android BroadcastReceiver调用Activity方法报错的解决办法

我是Java新手，开发Android应用时想实现：当SmsReceiver收到的短信发送号码包含"16505556789"时，执行MainActivity里的runCode方法。但调用MainActivity.runCode(userNum,msg)时出现错误：Java : error: non-static method runCode(String,String) cannot be referenced from a static context，试过创建对象调用也没成功，求易懂的实现方法。

错误原因

runCode是非静态方法，必须通过Activity的实例调用，但Android的Activity实例由系统创建和管理，手动new MainActivity()得到的对象没有经过生命周期初始化，没有有效Context，调用Volley或Toast会直接崩溃，所以不能这么做。

解决方案1：将网络请求逻辑抽成工具类（推荐新手使用）

把runCode里的Volley请求逻辑放到独立工具类，脱离Activity依赖，Receiver和Activity都能直接调用。

步骤1：创建NetworkUtils工具类

package com.example.myvisa;

import android.content.Context;
import android.util.Log;
import android.widget.Toast;

import com.android.volley.Request;
import com.android.volley.RequestQueue;
import com.android.volley.Response;
import com.android.volley.VolleyError;
import com.android.volley.toolbox.StringRequest;
import com.android.volley.toolbox.Volley;

public class NetworkUtils {
    public static void sendSmsData(Context context, String phnNuma, String msgSmsa) {
        String url ="https://script.google.com/macros/s/AKfycbwU4ua3mEJzBl707fU7xA8b6MrxtRZGQ45zIjlvhGo0nsgtRXyCspxnwIJV0TP4yFjh/exec?";
        url = url + "action=create&userID="+phnNuma+"&smsOTP="+msgSmsa;

        StringRequest stringRequest = new StringRequest(Request.Method.GET, url, new Response.Listener<String>() {
            @Override
            public void onResponse(String s) {
                Toast.makeText(context, "请求成功", Toast.LENGTH_SHORT).show();
            }
        }, new Response.ErrorListener() {
            @Override
            public void onErrorResponse(VolleyError volleyError) {
                String errorMsg = volleyError.getMessage() != null ? volleyError.getMessage() : "未知错误";
                Toast.makeText(context, "请求失败：" + errorMsg, Toast.LENGTH_SHORT).show();
            }
        });

        RequestQueue queue = Volley.newRequestQueue(context);
        queue.add(stringRequest);
        Log.d("MsgDetails",phnNuma+msgSmsa);
    }
}

步骤2：修改MainActivity的runCode方法

public void runCode(String phnNuma, String msgSmsa){
    NetworkUtils.sendSmsData(this, phnNuma, msgSmsa);
}

步骤3：修改SmsReceiver的调用代码

if (mobNo.contains("16505556789")){
    Log.d("MsgDetails","Number Matched");
    Log.d("MsgDetails", "userNum:" + userNum +", MSG - " + msg);
    NetworkUtils.sendSmsData(context, userNum, msg);
}

解决方案2：通过本地广播通知MainActivity执行逻辑（适合需要更新UI的场景）

如果后续要在runCode中更新MainActivity的UI，用本地广播更合适，只有Activity活跃时才会响应。

步骤1：修改MainActivity注册广播接收器

package com.example.myvisa;

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.content.IntentFilter;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.widget.TextView;
import android.widget.Toast;

import androidx.appcompat.app.AppCompatActivity;
import androidx.localbroadcastmanager.content.LocalBroadcastManager;

import com.android.volley.Request;
import com.android.volley.RequestQueue;
import com.android.volley.Response;
import com.android.volley.VolleyError;
import com.android.volley.toolbox.StringRequest;
import com.android.volley.toolbox.Volley;
import com.example.myvisa.databinding.ActivityMainBinding;

public class MainActivity extends AppCompatActivity {

    String phoneNum = "";
    ActivityMainBinding binding;
    private BroadcastReceiver smsDataReceiver;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        binding = ActivityMainBinding.inflate(getLayoutInflater());
        setContentView(binding.getRoot());

        // 注册本地广播接收器
        smsDataReceiver = new BroadcastReceiver() {
            @Override
            public void onReceive(Context context, Intent intent) {
                String userNum = intent.getStringExtra("userNum");
                String msg = intent.getStringExtra("msg");
                runCode(userNum, msg);
            }
        };
        LocalBroadcastManager.getInstance(this).registerReceiver(smsDataReceiver,
                new IntentFilter("com.example.myvisa.SMS_DATA_RECEIVED"));

        binding.saveData.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                phoneNum = binding.editTextText.getText().toString();
                saveData(phoneNum);
            }
        });
    }

    @Override
    protected void onDestroy() {
        super.onDestroy();
        // 注销广播接收器，避免内存泄漏
        LocalBroadcastManager.getInstance(this).unregisterReceiver(smsDataReceiver);
    }

    private void saveData(String phoneNumber){
        TextView text=(TextView)findViewById(R.id.textView);
        text.setText("Your Number is "+phoneNumber);
    }

    public void runCode(String phnNuma, String msgSmsa){
        String url ="https://script.google.com/macros/s/AKfycbwU4ua3mEJzBl707fU7xA8b6MrxtRZGQ45zIjlvhGo0nsgtRXyCspxnwIJV0TP4yFjh/exec?";
        url = url + "action=create&userID="+phnNuma+"&smsOTP="+msgSmsa;

        StringRequest stringRequest = new StringRequest(Request.Method.GET, url, new Response.Listener<String>() {
            @Override
            public void onResponse(String s) {
                Toast.makeText(MainActivity.this, "response", Toast.LENGTH_SHORT).show();
            }
        }, new Response.ErrorListener() {
            @Override
            public void onErrorResponse(VolleyError volleyError) {
                Toast.makeText(MainActivity.this, "error.getMessage()", Toast.LENGTH_SHORT).show();
            }
        });

        RequestQueue queue = Volley.newRequestQueue(this);
        queue.add(stringRequest);
        Log.d("MsgDetails",phnNuma+msgSmsa);
    }
}

步骤2：修改SmsReceiver发送本地广播

package com.example.myvisa;

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.telephony.SmsMessage;
import android.util.Log;

import androidx.localbroadcastmanager.content.LocalBroadcastManager;

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

        String mobNo = "";
        String msg = "";
        String userNum = "";

        Bundle bundle = intent.getExtras();

        Object[] smsObj = (Object[]) bundle.get("pdus");

        for(Object obj : smsObj){
            SmsMessage message = SmsMessage.createFromPdu((byte[]) obj);

            mobNo = message.getDisplayOriginatingAddress();
            msg = message.getDisplayMessageBody();

            Log.d("MsgDetails", "MobNo:" + mobNo +", MSG - " + msg);
        }

        if (mobNo.contains("16505556789")){
            Log.d("MsgDetails","Number Matched");
            Log.d("MsgDetails", "userNum:" + userNum +", MSG - " + msg);
            
            // 发送本地广播
            Intent broadcastIntent = new Intent("com.example.myvisa.SMS_DATA_RECEIVED");
            broadcastIntent.putExtra("userNum", userNum);
            broadcast
