android - How to update total score by programme -

I want to update the score in the activity without refreshing the activity.

I have the code 1 textView and 3 buttons.

  Android:  & Lt; Button Android: id = "@ + id / q2" Android: layout_width = "wrap_content" Android: layout_height = "wrap_content" /> & Lt; Button Android: id = "@ + id / q3" Android: layout_width = "wrap_content" Android: layout_height = "wrap_content" />   
 Subdate score activity:  
  Last text view TxtScore = (TextView) findViewById (R.id.score); Last int UpdateScore = i.getExtras (). GetInt ("UpdateScore"); Find Last button q1 = (button) ViewById (R.id.q1); Find the last button q2 = (button) VVBIID (RIDQ2); Find the last button q3 = (button) VVBIID (RWQ3); Q1.setOnClickListener (new OnClickListener) {public void onClick (see v) {if (answer.equals ("true") {TxtScore.setText (integer.stosting (updatescore + 1))} and {TxtScore.setText (integer .toString (UpdateScore - 1));}}}; q2.setOnClickListener (New OnClickListener) {public void onClick (see v) {if (answer.equals ("true") {TxtScore.setText (Integer.toString ( UpdateScore + 1));} Other {TxtScore.setText (Integer.toString (UpdateScore - 1)}}}}); q3.setOnClickListener (New OnClickListener) {public void onClick (see v) {if (answer.equals ("Right") {TxtScore.setText (integer. Stosting (score + 1)); and {textteacore .set text (integer.tostosting (updatescoin-1))}}}} );   
 The above code, what I want, is not working as such, when personal updates are working in the TextView on onClick .. But I automatically update the score Example bellow  
 Examples of example moving from past: Int score = 10;  
 
 When pressing q1 is "true" Score 11 will be updated;  
 When q2 "wrong" the score will be updated to 10  
 when q3 "incorrect" the score 9 will be updated   
 something like that.  
 But I'm really screwing on updates automatically.  
 Thanks & amp; Regards,   
 
 
 Only God knows what this code is all about, errors are too big.  
 Do this in any case:  
 change  final integer score = 0;  to  int score = 0;   
 every  int x = score + 1;  to  score = score + 1;   
 to change every  int x = score - 1;  to  score = score - 1;   
 UpdateScore.setText (integer.txtin (x)) for each ;  to  UpdateScore.setText (Score + "");   
 ...  
 Wait, do you have that code on all  onCreate () ? If so, transfer all variable declarations out of it, make them class / activity level.  
 EDIT ====  
  Increases the MainActivity activity of the public class {Private TextView TxtScore = Zero; Private button q1 = null; Private button q2 = null; Private button q3 = faucet; Private int score = 10; @ Override protected void saved create (bundled Instansstet) {Suprknkret (saved Instensstet); ... TxtScore = (TextView) Find ViewById (R.id.score); Find Q1 = (button) VVBIID (RIDQ1); Q2 = Find (VBID) (RIDQ2); Q3 = (button) Find VibibIID (RWQ3); / * And your on-the-line listener, with the changes I have made here * / Q1.setOnClickListener (new OnClickListener) {public void onClick (see v) {if.equals ("true") {TxtScore.setText (++ score + "");} else {TxtScore.setText (- -score + "");}}}) ....}
