將微調值傳遞給廣播接收器

Question

我正在製作一個應用程序，它從mySQL庫中檢索電話號碼，使用這些值填充微調器，並在計時器從微調列表中調用一個號碼。我的問題是如何解析這個微調電話號碼到電話被叫的活動？我將刪除不必要的代碼部分。

public class MainActivity extends AppCompatActivity implements Spinner.OnItemSelectedListener{ 

    private Spinner spinner; 
    private ArrayList<String> brojevi; 
    private JSONArray result; 
    private TextView textViewPoziv,textViewSms; 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 

     //Inicijalizacija liste brojeva 
     brojevi = new ArrayList<String>(); 

     //Inicijalizacija spinnera 
     spinner = (Spinner) findViewById(R.id.spinner); 
     spinner.setOnItemSelectedListener(this); 

     textViewPoziv = (TextView) findViewById(R.id.textViewPoziv); 
     textViewSms = (TextView) findViewById(R.id.textViewSms); 

     //pozivanje URL-a 
     getData(); 
} 


    public void startAlert(View view) { 
     EditText text = (EditText) findViewById(R.id.time); 
     int i = Integer.parseInt(text.getText().toString()); 
     Intent intent = new Intent(this, SampleAlarmReceiver.class); 
     PendingIntent pendingIntent = PendingIntent.getBroadcast(this.getApplicationContext(), 234324243, intent, 0); 
     AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE); 
     alarmManager.set(AlarmManager.RTC_WAKEUP, System.currentTimeMillis() + (i * 1000), pendingIntent); 
    } 

    @Override 
    public void onItemSelected(AdapterView<?> parent, View view, int position, long id) { 
     String text = spinner.getSelectedItem().toString(); 
     textViewPoziv.setText(getPoziv(position)); 
     textViewSms.setText(getSms(position)); 
    } 

    @Override 
    public void onNothingSelected(AdapterView<?> parent) { 
     textViewPoziv.setText(""); 
     textViewSms.setText(""); 
    } 
} 

我應該傳遞微調值：

public class SampleAlarmReceiver extends WakefulBroadcastReceiver { 

    @Override 
    public void onReceive(Context context, Intent intent) { 


     PackageManager pm = context.getPackageManager(); 
     int hasPerm = pm.checkPermission(Manifest.permission.CALL_PHONE,context.getPackageName()); 
     if (ContextCompat.checkSelfPermission(context, Manifest.permission.CALL_PHONE)== PackageManager.PERMISSION_GRANTED){ 
      Intent myIntent = new Intent(Intent.ACTION_CALL, Uri.parse("tel:" + "+" + **SpinnerValue**));; 
      myIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); 
      context.startActivity(myIntent); 
     } 
    } 
} 

Answer 1

pass spinner value in intent so that you will retrieve in onReceive() method 





    public class SampleAlarmReceiver extends WakefulBroadcastReceiver { 

     @Override 
     public void onReceive(Context context, Intent intent) { 
      String spinnerValue=""; 
      if(intent!=null && intent.getStringExtra("key")!=null){ 
       spinnerValue=intent.getStringExtra("key"); 
      } 

      PackageManager pm = context.getPackageManager(); 
      int hasPerm = pm.checkPermission(Manifest.permission.CALL_PHONE,context.getPackageName()); 
      if (ContextCompat.checkSelfPermission(context, Manifest.permission.CALL_PHONE)== PackageManager.PERMISSION_GRANTED){ 
       Intent myIntent = new Intent(Intent.ACTION_CALL, Uri.parse("tel:" + "+" + **SpinnerValue**));; 
       myIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); 
       context.startActivity(myIntent); 
      } 
     } 
    } 





public void startAlert(View view) { 
     EditText text = (EditText) findViewById(R.id.time); 
     int i = Integer.parseInt(text.getText().toString()); 
     Intent intent = new Intent(this, SampleAlarmReceiver.class); 
     intent.putExtra("key", "Spinner Value"); 
     PendingIntent pendingIntent = PendingIntent.getBroadcast(this.getApplicationContext(), 234324243, intent, 0); 
     AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE); 
     alarmManager.set(AlarmManager.RTC_WAKEUP, System.currentTimeMillis() + (i * 1000), pendingIntent); 
    } 



I hope it will work for you
