ChooseLanguageFragment.java

Intent explicitGetNumberServiceIntentUSA = new Intent(getActivity(), GetNumberService.class);
explicitGetNumberServiceIntentUSA.putExtra("country", "USA");
getActivity().startService(explicitGetNumberServiceIntentUSA);

这就是调用GetNumberService的方式。

这是从GetNumberService.java传递arraylist的方式

Intent mobileNumbersIntent = new Intent();
mobileNumbersIntent.putStringArrayListExtra("mobileNumbers", mobileNumberList);
mobileNumbersIntent.setAction(ChooseNumber1.MobileNumberBroadcastReceiver.MOBILE_NO_RECEIVER);
mobileNumbersIntent.addCategory(Intent.CATEGORY_DEFAULT);
mobileNumbersIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); //this is needed when callling startActivity() outisde an Activity            
sendBroadcast(mobileNumbersIntent);

在onHandleIntent（）方法中。

GetNumberService可以完美地完成其工作。

ChooseNumber1.java

public class ChooseNumber1 extends AppCompatActivity {
    private MobileNumberBroadcastReceiver receiver;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        IntentFilter intentFilter = new IntentFilter(MobileNumberBroadcastReceiver.MOBILE_NO_RECEIVER);
        intentFilter.addCategory(Intent.CATEGORY_DEFAULT);
        receiver = new MobileNumberBroadcastReceiver();
        registerReceiver(receiver, intentFilter);
        setContentView(R.layout.activity_choose_number1);
        Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);
        getSupportActionBar().setDisplayHomeAsUpEnabled(true);
    }

    @Override
    protected void onDestroy(){
        unregisterReceiver(receiver);
        super.onDestroy();
    }

    public class MobileNumberBroadcastReceiver extends BroadcastReceiver {

        public static final String MOBILE_NO_RECEIVER = "abcd";
        ArrayList<String> mobileNumbersList = new ArrayList<>();
        ListView mobileNumberListView;
        ArrayAdapter<String> mobileNumberAdapter;

        @Override
        public void onReceive(Context context, Intent intent) {
          //  if(intent.getAction().equals(GetNumberService.MOBILE_NUMBER_LIST_PASS_ACTION)){
                mobileNumbersList = intent.getStringArrayListExtra("mobileNumberList");
         //   }
            mobileNumberAdapter = new ArrayAdapter<String>(new ChooseNumbers(),
                    R.layout.list_item_numbers, R.id.list_item_number_textview, mobileNumbersList);

            mobileNumberListView = (ListView) findViewById(R.id.listViewNumberList);
            mobileNumberListView.setAdapter(mobileNumberAdapter);
        }
    }

}

PS 2：

问题是，我无法在ChooseNumber1.java或ChooseNumbersFragment.java中收到mobileNumbersIntent。我认为问题出在BroadcastManager.java。如果我进行调试，它将转到Handler.java和其他几个类，最后是mId
= -1，并且堆栈跟踪中没有错误。我被感动了

PS：在查看了Stackoverflow中的大量示例和答案之后，我对代码进行了很多修改。这是我的最新代码。看起来问题出在意图过滤器和/或使用动作获取意图。请帮我。谢谢。
