android添加额外的并以编程方式调用

Question

我正在尝试通过我的应用程序通过放置额外数据来调用电话，但我无法在通话期间接收到该数据，可以解释一下我哪里错了下面是我调用电话和接听电话的代码

String uri = "tel:"+my_name;
        Intent callIntent = new Intent(Intent.ACTION_CALL, Uri.parse(uri));
        callIntent.putExtra("data", "mynewdata");
        callIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        _context.startActivity(callIntent);

和调用接收者

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

        final Bundle bundle = intent.getExtras();
        if(bundle != null) {
            showToast(intent.getExtras().getString("data"));
        } 

        if (intent.getAction().equals("android.intent.action.PHONE_STATE")) { 
            String state = intent.getStringExtra(TelephonyManager.EXTRA_STATE);
            Log.d(TAG,"PhoneStateReceiver**Call State=" + state);
            if (state.equals(TelephonyManager.EXTRA_STATE_IDLE)) {
                if(recieveCall){

                }
                Log.d(TAG,"PhoneStateReceiver**Idle");
            } else if (state.equals(TelephonyManager.EXTRA_STATE_RINGING)) { 

            } else if (state.equals(TelephonyManager.EXTRA_STATE_OFFHOOK)) {
            }
        } else if (intent.getAction().equals("android.intent.action.NEW_OUTGOING_CALL")) { 
            // Outgoing call
            String outgoingNumber = intent.getStringExtra(Intent.EXTRA_PHONE_NUMBER);
            Log.d(TAG,"PhoneStateReceiver **Outgoing call " + outgoingNumber);

            setResultData(null); // Kills the outgoing call

        } else {
            Log.d(TAG,"PhoneStateReceiver **unexpected intent.action=" + intent.getAction());
        }
          }
    }

我可以完美地接听电话，甚至广播也可以正常工作，但我没有从 Intent “intent.getExtras().getBoolean("data")”获取数据

在这里您需要创建一个 java 文件(我们将其命名为 Constants.java):

public class Constants
{
 public static boolean data;
 public static String str = "";
}

现在查看我在项目中所做的更改以及评论。

String uri = "tel:"+my_name;
        Intent callIntent = new Intent(Intent.ACTION_CALL, Uri.parse(uri));
        Constants.data = true; /*see change, set data in Constants.data*/
        Constants.str = "some data to pass..."; /*see change*/
        callIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        _context.startActivity(callIntent);

现在在广播接收器中看到所做的更改...

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

        final Bundle bundle = intent.getExtras();
        if(bundle != null && Constants.data) { /*changes done, get boolean from the Constants.data*/
            showToast("hi i have recieve");
            showToast(Constants.str); /*changes done*/
        } 

        if (intent.getAction().equals("android.intent.action.PHONE_STATE")) { 
            String state = intent.getStringExtra(TelephonyManager.EXTRA_STATE);
            Log.d(TAG,"PhoneStateReceiver**Call State=" + state);
            if (state.equals(TelephonyManager.EXTRA_STATE_IDLE)) {
                if(recieveCall){

                }
                Log.d(TAG,"PhoneStateReceiver**Idle");
            } else if (state.equals(TelephonyManager.EXTRA_STATE_RINGING)) { 

            } else if (state.equals(TelephonyManager.EXTRA_STATE_OFFHOOK)) {
            }
        } else if (intent.getAction().equals("android.intent.action.NEW_OUTGOING_CALL")) { 
            // Outgoing call
            String outgoingNumber = intent.getStringExtra(Intent.EXTRA_PHONE_NUMBER);
            Log.d(TAG,"PhoneStateReceiver **Outgoing call " + outgoingNumber);

            setResultData(null); // Kills the outgoing call

        } else {
            Log.d(TAG,"PhoneStateReceiver **unexpected intent.action=" + intent.getAction());
        }
          }
    }

希望这能解决您如何传递数据的问题
