Question

我是Android的初学者，我正在寻找具有特定药物的药房的应用程序。所有抛出短信。所以应用程序收到一条短信，其中包含所有药房的名称，将它们保存在一个名为OurString的数组中，但这个数组是广播接收器类。我有trid发送字符串，但是当我尝试了数组时没有工作。所以如何将数组发送到其他类，以查看列表视图中的药店名称。
这是我的BroadcastRecieve类：

 public void onReceive(Context context, Intent intent) {
    Bundle bundle = intent.getExtras();
    SmsMessage[] msgs = null ;
    String[] OurString = null;
    String str = " ";
    if(bundle != null)
    {
        Object[] pdus = (Object[]) bundle.get("pdus");
        msgs = new SmsMessage[pdus.length];

        for(int i=0;i<msgs.length;i++)
        {
            msgs[i]= SmsMessage.createFromPdu((byte[])pdus[i]);
            str += msgs[i].getMessageBody().toString();
            OurString = msgs[i].getMessageBody().toString().split(" ");
            str += " : ";

        }
        for(int i=0;i<OurString.length;i++)
        {
            str += "(";
            str += OurString[i];
            str += ")";

        }
        Toast.makeText(context,str,Toast.LENGTH_SHORT).show();
        Intent broadcastIntent = new Intent();
        broadcastIntent.setAction("SMS_RECEIVED_ACTION");
        broadcastIntent.putExtra("sms", str);
        context.sendBroadcast(broadcastIntent);




    }
}

这是我想发送String的地方，我使用pharmacies数组来测试listview，我想用OurString替换它：

public class MedName extends ListActivity {
String[] pharmacies = {"pharmacy 1","pharmacy 2"};
Button btnSendSMS,btnShowMap;
EditText editText;
IntentFilter intentFilter,intentFilter1;

private BroadcastReceiver intentReceiver = new BroadcastReceiver() {
    @Override
    public void onReceive(Context context, Intent intent) {
        TextView SMSes = (TextView)findViewById(R.id.tv);
        SMSes.setText(intent.getExtras().getString("sms"));

    }
};

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.medicinename);
    btnShowMap = (Button) findViewById(R.id.btnShowMap);
    btnShowMap.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Intent showmap = new Intent("com.example.rana.me_lo.MapsActivity");
            startActivity(showmap);
        }
    });
    btnSendSMS = (Button) findViewById(R.id.btnSendSMS);
    editText = (EditText) findViewById(R.id.etMeName);
    btnSendSMS.setOnClickListener(new View.OnClickListener() {
       @Override
       public void onClick(View v) {
           sendSMS("5666",editText.getText().toString());
      }
    });
    TabHost tabHost = (TabHost) findViewById(R.id.tabHost);
    tabHost.setup();
    TabHost.TabSpec spec1 = tabHost.newTabSpec("Search");
    spec1.setContent(R.id.tab1);
    spec1.setIndicator(" Search",getResources().getDrawable(R.drawable.picture));

    TabHost.TabSpec spec2 = tabHost.newTabSpec("Result");
    spec2.setContent(R.id.tab2);
    spec2.setIndicator("Result");
     tabHost.addTab(spec1);
     tabHost.addTab(spec2);
     intentFilter =new IntentFilter();
    intentFilter.addAction("SMS_RECEIVED_ACTION");

     setListAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, pharmacies));
}

private void sendSMS(String number, String message) {
    String SENT = "SMS_SENT";
    String DELIVERED = "SMS_DELIVERED";
    PendingIntent sentPI = PendingIntent.getBroadcast(this,0,new Intent(SENT),0);
    PendingIntent deliveredPI = PendingIntent.getBroadcast(this,0,new Intent(DELIVERED),0);
    registerReceiver(new BroadcastReceiver() {
        @Override
        public void onReceive(Context context, Intent intent) {
            switch (getResultCode())
            {
                case Activity.RESULT_OK:
                    Toast.makeText(getBaseContext(),"SMS sent",Toast.LENGTH_SHORT).show();
                    break;
                case SmsManager.RESULT_ERROR_GENERIC_FAILURE:
                    Toast.makeText(getBaseContext(), "Generic failure", Toast.LENGTH_SHORT).show();
                    break;
                case SmsManager.RESULT_ERROR_NO_SERVICE:
                    Toast.makeText(getBaseContext(), "No service", Toast.LENGTH_SHORT).show();
                    break;
                case SmsManager.RESULT_ERROR_NULL_PDU:
                   Toast.makeText(getBaseContext(), "Null PDU", Toast.LENGTH_SHORT).show();
                    break;
                case SmsManager.RESULT_ERROR_RADIO_OFF:
                    Toast.makeText(getBaseContext(), "Radio off", Toast.LENGTH_SHORT).show();
                    break;
            }
        }
    },new IntentFilter(SENT));
    registerReceiver(new BroadcastReceiver() {
      @Override
        public void onReceive(Context context, Intent intent) {
            switch (getResultCode())
            {
                case Activity.RESULT_OK:
                    Toast.makeText(getBaseContext(), "SMS delivered", Toast.LENGTH_SHORT).show();
                    break;
                case Activity.RESULT_CANCELED:
                    Toast.makeText(getBaseContext(), "SMS not delivered", Toast.LENGTH_SHORT).show();
                    break;
            }
        }
    },new IntentFilter(DELIVERED));
    SmsManager sms = SmsManager.getDefault();
    sms.sendTextMessage(number,null,message,sentPI,deliveredPI);
}

@Override
public void onListItemClick(ListView l, View v, int position, long id) {

   Toast.makeText(this,"You have selected "+pharmacies[position],Toast.LENGTH_SHORT).show();
}

@Override
protected void onResume() {
    registerReceiver(intentReceiver,intentFilter);

    super.onResume();
}

@Override
protected void onPause() {
    unregisterReceiver(intentReceiver);

    super.onPause();
}

}

您可以发送和接收这样的数组：

发送：

Bundle b=new Bundle();
b.putStringArray(key, new String[]{value1, value2});
Intent i=new Intent(context, Class);
i.putExtras(b);

接收：

Bundle b=this.getIntent().getExtras();
String[] array=b.getStringArray(key);

Answer 2

我遇到了同样的问题，并为我设置了以下标志 {Main}中的Intent intent = new Intent(context,MainActivity.class); intent.putStringArrayListExtra("list", arraylistOfStrings); PendingIntent pIntent = PendingIntent.getActivity(this, 0, intent,PendingIntent.FLAG_CANCEL_CURRENT);

Bundle bundle = getIntent().getExtras();
if (bundle != null) {
arrayList= bundle.getStringArrayList("list");
}

如何将数组从broadcastReciver类发送到MainActivity
