Question

我正在前台显示的服务中需要发送短信，我正在使用服务类中的以下代码

SmsManager smsManager = SmsManager.getDefault();
smsManager.sendTextMessage(phoneNo, null, "text", null, null);

我已经获得了以下权限android：name =“ android.permission.SEND_SMS”，但它没有工作，没有消息正在发送

Answer 1

声明：

public static final int PERMISSION_CODE_SEND_SMS  = 123;

检查是否授予许可：

if (checkSelfPermission(android.Manifest.permission.SEND_SMS)
        != PackageManager.PERMISSION_GRANTED) {
    requestPermissions(new String[]{android.Manifest.permission.SEND_SMS},
            PERMISSION_CODE_SEND_SMS);

    return;
}

现在处理响应：

@Override
public void onRequestPermissionsResult(int requestCode,
    String permissions[], int[] grantResults) {
switch (requestCode) {
    case  PERMISSION_CODE_SEND_SMS: {
        if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {

            // permission was granted send SMS now

        } else {

            // permission denied ask again
        }
        return;
    }


  }
}

在主要活动中检查权限

   private void checkForSmsPermission() {
    if (ActivityCompat.checkSelfPermission(this,
            Manifest.permission.SEND_SMS) != PackageManager.PERMISSION_GRANTED) {
        ActivityCompat.requestPermissions(this,
                new String[]{Manifest.permission.SEND_SMS},
                MY_PERMISSIONS_REQUEST_SEND_SMS);
    } else {
        // Permission already granted. Enable the SMS button.
       permission=1;
    }
}


        @Override
     public void onRequestPermissionsResult(int requestCode,
                                       String permissions[], int[] grantResults) {
    // For the requestCode, check if permission was granted or not.
         switch (requestCode) {
        case MY_PERMISSIONS_REQUEST_SEND_SMS: {
            if (permissions[0].equalsIgnoreCase(Manifest.permission.SEND_SMS)
                    && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                // Permission was granted. Enable sms button.
                permission = 1;
            } else {
                // Permission denied.
                permission = 0;
                // Disable the sms button.

            }
         }
        }
      }

并通过意图将权限详细信息作为权限变量（int）发送到服务类

       checkForSmsPermission();
       final Intent intent = new Intent(this, Chat.class);
       intent.putExtra("permission",permission);
       ContextCompat.startForegroundService(this, intent);

服务类别中的chked许可并发送了消息（按下发送按钮时）

                if (permission==1) {
                SmsManager smsManager = SmsManager.getDefault();
                smsManager.sendTextMessage(phoneNo, null, message, null, null);
                Toast.makeText(getApplicationContext(), "SMS sent.",
                        Toast.LENGTH_LONG).show();
            } else
                {
                Toast.makeText(getApplicationContext(),
                        "SMS faild, please try again.", Toast.LENGTH_LONG).show();
                return;
            }

在Android 4.4及更高版本的服务中使用Smsmanager发送短信
