I need to make an app that sends an SMS message after showing a progress bar in increments of 10. I have the action bar set up and I think I should use AsyncTask? The user is inputing number and message into the main activity, and that's where I have the SendSMS method set up, not sure how to make this work so that it forwards to AsyncTask and calls on that method there.
public class MainActivity extends AppCompatActivity {
private int MY_PERMISSIONS_REQUEST_SMS_RECEIVE = 10;
private static final String SMS_SENT = "SMS_SENT";
private static final String SMS_DELIVERED= "SMS_DELIVERED";
private EditText etPoruka;
private EditText etBroj;
private ProgressDialog progressDialog;
private Context context = null;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
initWidgets();
ActivityCompat.requestPermissions(this,
new String[]{Manifest.permission.RECEIVE_SMS},
MY_PERMISSIONS_REQUEST_SMS_RECEIVE);
}
private void initWidgets() {
etPoruka = findViewById(R.id.etPoruka);
etBroj = findViewById(R.id.etBroj);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.menu_main, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.action_send:
MyAsyncTask<Void, Void, Void> updateTask = new MyAsyncTask<Void, Void, Void>(context);
updateTask.execute();
break;
case R.id.action_sent:
Toast.makeText(this, R.string.add_test, Toast.LENGTH_LONG).show();
// BROADCAST RECEIVER ??
break;
case R.id.action_received:
Toast.makeText(this, R.string.add_test, Toast.LENGTH_LONG).show();
//BROADCAST RECEIVER ??
//BOUND SERVICE
break;
case R.id.action_exit:
final AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this);
builder.setTitle("Close app");
builder.setMessage("Are you sure?");
builder.setPositiveButton("Yes", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialogInterface, int i) {
finish();
}
});
builder.setNegativeButton("No", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialogInterface, int i) {
dialogInterface.dismiss();
}
});
AlertDialog dialog = builder.create();
dialog.show();
}
return true;
}
public void sendSMS() {
try{
SmsManager smgr = SmsManager.getDefault();
smgr.sendTextMessage(etBroj.getText().toString(),null,etPoruka.getText().toString(),null,null);
Toast.makeText(MainActivity.this, "SMS sent successfully", Toast.LENGTH_SHORT).show();
}
catch (Exception e){
Toast.makeText(MainActivity.this, "Error", Toast.LENGTH_SHORT).show();
}
}
}
ASYNCTASK
public class MyAsyncTask extends AsyncTask {
private final String DIALOG_MESSAGE = "Sending message";
private ProgressDialog mDialog = null;
private void setDialog(Context context) {
this.mDialog = new ProgressDialog(context);
this.mDialog.setMessage(DIALOG_MESSAGE);
this.mDialog.setCancelable(false);
}
public MyAsyncTask(Context context) {
this.setDialog(context);
}
@Override
protected void onPreExecute() {
this.mDialog.show();
}
@Override
protected Result doInBackground(Params... arg0) {
try {
Thread.sleep(2000);
} catch (InterruptedException e) {
e.printStackTrace();
}
return null;
}
@Override
protected void onPostExecute(Result result) {
if (this.mDialog.isShowing()) {
this.mDialog.dismiss();
}
} }
