问题
I am new to Android and I have bound my application completely but I wish to a change now in it.
When someone sends an sms, I want to display a confirmation dialog for sending sms asking for send or not. And I have to make a common class for that I have written the source code and it works fine but if user does not click on Yes or Cancel the dialog goes out but I wish that it will still display until user does not click on Yes or Cancel button.
How it can be solved?
public void send_SMS( final String message)
{
try{
AlertDialog.Builder dialog = new AlertDialog.Builder(ctx);
dialog.setTitle("Send SMS");
dialog.setMessage("Are U sure want to Send SMS");
dialog.setCancelable(true);
dialog.setPositiveButton("Yes", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
// TODO Auto-generated method stub
sentpi = PendingIntent.getBroadcast(ctx, 0, new Intent(SENT),0);
delpi = PendingIntent.getBroadcast(ctx, 0, new Intent(DELIVERED), 0);//
String id = message.substring(3, 4);
int msgId = Integer.valueOf(id, 16).intValue();
if(dba.IsConOpenOrClose()==false)
dba.Open();
if(ConstantClass.SelectCord.equals("All")){
if(msgId == 3 || msgId == 9){
devId = message.substring(4, 20);
ConstantClass.CurrentId = devId;
strSql = new String("SELECT * FROM "+ ConstantClass.dbName[2] + " WHERE " + DataBaseAdapter.Key_DevID + " = ?");
cur = dba.ExecuteSelect(strSql, devId);
if(cur!=null)
cur.moveToFirst();
int cordId = cur.getInt(cur.getColumnIndex(DataBaseAdapter.Key_DevCoordId));
phoneNumber = dba.getSendSmsMobileNo(cordId);
dba.prcUpdateOrClean(devId, 1);
cur.close();
}
}else{
phoneNumber = dba.getSendSmsMobileNo(dba.CurrentWorkingCoordinator(DataBaseAdapter.Key_SendCoord, 1));
/*********now getting the Field smsProcess Update for particular devices ********************/
if(msgId == 3 || msgId == 9 || msgId == 7){
devId = message.substring(4, 20);
if(dba.IsConOpenOrClose()==false)
dba.Open();
ConstantClass.CurrentId = devId;
dba.prcUpdateOrClean(devId, 1);
}else if(msgId == 15 || msgId == 13 || msgId == 11 || msgId == 1){
if (dba.IsConOpenOrClose()==false)
dba.Open();
phoneNumber = dba.getSendSmsMobileNo(dba.CurrentWorkingCoordinator(DataBaseAdapter.Key_SendCoord, 1));
if(phoneNumber.length()==11){

}
devId = "000000" + pdNo;
ConstantClass.CurrentId = devId;
dba.prcUpdateOrClean(devId, 1);
}
}
SmsManager sms = SmsManager.getDefault();

回答1:
dialog.setCancelable(true); should be like dialog.setCancelable(false);
It prevents closure of alert dialog when user presses back button :)
