I need to make my app such that, only when the user click on the re_b1 button, it should show the progress Dialog until the Button‘s progress finished (because sometimes this activity freezes until the progress finished). Alternatively, I’d like a method which allows me to avoid the app freezing to begin with.
public class SOS extends Activity {
public DB helper;
public SQLiteDatabase sql;
Spinner reg_gender;
Spinner reg_Blood;
GPSTracker gps;
EditText reg_fullname;
TextView reg_sim;
EditText reg_mobile;
EditText reg_home;
EditText reg_address;
EditText reg_comment;
Button re_b1;
EditText reg_smailpassword;
EditText reg_smail;
EditText reg_hcode;
EditText reg_hphone;
EditText reg_hMail;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_sos);
helper=new DB(this);
sql= helper.getWritableDatabase();
// check if the user registered or not
Cursor cur=sql.query("users", null, null, null, null, null, null);
if(cur.moveToNext()){
sql.close();
Intent call = new Intent(SOS.this, MainSos.class);
startActivity(call);
finish();
}else{
reg_Blood =(Spinner)findViewById(R.id.reg_Blood);

Here is a good example of using
progress dialogNormally you would use this in anAsyncTaskbut I don’t see any network stuff going on sorunOnUiThreadmay work for you. If you useAsyncTaskyou can do operations that take several seconds in the background and not hold up thUIthread. Hope this helps
