how to pass data intent in different textview in android -


i have 3 activities layouts. in first layout want user input number had displayed (almost same captcha) , in second layout too. next want pass result last layout.

here code.

firstlayout:

edittext periksaanstxt = (edittext) findviewbyid(r.id.et);     int periksaans = integer.valueof(periksaanstxt.gettext().tostring());     intent hasilintent = new intent(this, soal2.class);     int hasilbnormal;     int hasilbtotal;      if (periksaans == 12){         hasilbnormal = 1;         hasilintent.putextra("hasilbnormal1",hasilbnormal);     }else {         hasilbtotal = 1;         hasilintent.putextra("hasilbtotal1", hasilbtotal);     }     startactivity(hasilintent);

the second:

edittext periksaanstxt = (edittext) findviewbyid(r.id.et);      int periksaans = integer.valueof(periksaanstxt.gettext().tostring());     intent hasilintent = new intent(this, hasilactivity.class);      int hasilbnormal;     int hasilbmerahhijau;     int hasilbtotal;       if (periksaans == 8){         hasilbnormal = 1;         hasilintent.putextra("hasilbnormal2",hasilbnormal);       }else if (periksaans == 3){         hasilbmerahhijau = 1;         hasilintent.putextra("hasilbmerahhijau1", hasilbmerahhijau);      }else {         hasilbtotal = 1;         hasilintent.putextra("hasiltotal2", hasilbtotal);     }     startactivity(hasilintent);

and layout shows result :

intent hasilintent = getintent();   integer hasilnormal1 = hasilintent.getintextra("hasilbnormal1",1);   integer hasilnormal2 = hasilintent.getintextra("hasilbnormal2",1);   integer hasiltotal1 = hasilintent.getintextra("hasilbtotal1",1);   integer hasiltotal2 = hasilintent.getintextra("hasilbtotal2",1);   integer hasilmerahhijau = hasilintent.getintextra("hasilbmerahhijau1",1);    textview hasilnormalview = (textview) findviewbyid(r.id.txtnormal);   textview hasilmerahhijauview = (textview)findviewbyid(r.id.txtmerahhijau);   textview hasiltotalview = (textview) findviewbyid(r.id.txttotal);    float bnormal = (hasilnormal1 + hasilnormal2)/2 *100;   string bnormalstr = string.valueof(bnormal);   float bmerahhijau = hasilmerahhijau*100;   string bmerahhijaustr = string.valueof(bmerahhijau);    float btotal = (hasiltotal1 + hasiltotal2)/2*100;   string btotalstr = string.valueof(btotal);    hasilnormalview.settext("normal : " + bnormalstr + '%');   hasilmerahhijauview.settext("buta warna merah + hijau : " + bmerahhijaustr + '%');   hasiltotalview.settext("buta warna total : " + btotalstr + '%');

so if input number 12 in layout1 or 8 in layout 2, hasilbnormal increase , other not increase (do nothing), hv problem here. if hasilbnormal increase others, please me fix this.

here xml in third layout:

<textview     android:layout_width="wrap_content"     android:layout_height="wrap_content"     android:textappearance="?android:attr/textappearancemedium"     android:id="@+id/txtnormal"     android:layout_alignparenttop="true"     android:layout_alignparentleft="true"     android:layout_margintop="110dp" />   <textview     android:layout_width="wrap_content"     android:layout_height="wrap_content"     android:textappearance="?android:attr/textappearancemedium"     android:id="@+id/txtmerahhijau"     android:layout_below="@+id/txtnormal"     android:layout_alignparentleft="true"     android:layout_alignparentstart="true" />  <textview     android:layout_width="wrap_content"     android:layout_height="wrap_content"     android:textappearance="?android:attr/textappearancemedium"     android:id="@+id/txttotal"     android:layout_below="@+id/txtmerahhijau"     android:layout_alignparentleft="true"     android:layout_alignparentstart="true" />

i don't understand what's purpose of code, or semantics of variables, believe want set default value 0 on getintextras

integer hasilnormal1 = hasilintent.getintextra("hasilbnormal1", 0);  integer hasilnormal2 = hasilintent.getintextra("hasilbnormal2", 0); ...

also, seems losing contents of first intent on second activity.

in second activity should copy contents of first intent second intent:

hasilintent.putextra("hasilbnormal1", getintent().getintextra("hasilbnormal1", 0)); hasilintent.putextra("hasilbtotal1", getintent().getintextra("hasilbtotal1", 0));
