嗨,我正在使用此代码发送任何号码的短信,但它是第一次工作,没有下一次。任何修复? MY_PERMISSION_REQUEST_SEND_SMS有问题吗?有没有其他简短的方法发送短信?
protected void SendSms() {
phonenumber=number.getText().toString();
message= txt.getText().toString();
if (ContextCompat.checkSelfPermission(this,
Manifest.permission.SEND_SMS)
!= PackageManager.PERMISSION_GRANTED) {
if (ActivityCompat.shouldShowRequestPermissionRationale(this,
Manifest.permission.SEND_SMS)) {
} else {
ActivityCompat.requestPermissions(this,
new String[]{Manifest.permission.SEND_SMS},
MY_PERMISSIONS_REQUEST_SEND_SMS);
}
}
}
@Override
public void onRequestPermissionsResult(int requestCode,String permissions[],
int[] grantResults) {
switch (requestCode) {
case MY_PERMISSIONS_REQUEST_SEND_SMS: {
if (grantResults.length > 0
&& grantResults[0] == PackageManager.PERMISSION_GRANTED)
{
SmsManager smsManager = SmsManager.getDefault();
smsManager.sendTextMessage(phonenumber, 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;
}
}
}

当您已拥有发送SmS权限
的权限时,您没有这个条件将else用于外部if并执行发送短信代码

这是因为如果获得许可,您错过了调用smsManager发送短信的权利 更好地制作方法,
private void smsSend(){
SmsManager smsManager = SmsManager.getDefault();
smsManager.sendTextMessage(phonenumber, null, message, null,
null);
Toast.makeText(getApplicationContext(), "SMS sent.",
Toast.LENGTH_LONG).show();
}
if (ContextCompat.checkSelfPermission(this,
Manifest.permission.SEND_SMS)
!= PackageManager.PERMISSION_GRANTED) {
if (ActivityCompat.shouldShowRequestPermissionRationale(this,
Manifest.permission.SEND_SMS)) {
} else {
ActivityCompat.requestPermissions(this,
new String[]{Manifest.permission.SEND_SMS},
MY_PERMISSIONS_REQUEST_SEND_SMS);
}
}
else{
smsSend(); //call method if already granted
}
并在授予权限后调用此方法,
@Override
public void onRequestPermissionsResult(int requestCode,String permissions[],
int[] grantResults) {
switch (requestCode) {
case MY_PERMISSIONS_REQUEST_SEND_SMS: {
if (grantResults.length > 0
&& grantResults[0] == PackageManager.PERMISSION_GRANTED)
{
smsSend(); //call method after permission grant
} else {
Toast.makeText(getApplicationContext(),
"SMS faild, please try again.",
Toast.LENGTH_LONG).show();
return;
}
}
}
}
