you need to add a button to your .xml file like this :
<Button
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Goal"
android:layout_margin="8dp"
android:onClick="add1ForTeamA"
android:id="@+id/Three_Button_B"/>
then if you will notice that the android:onclick has been set to the add1ForTeamA method. Go to the mainActivity.java file and add this method
`public void addOneForTeamA(View view) {
scoreTeamA = scoreTeamA + 1;
displayForTeamA(scoreTeamA);
}`
public void displayForTeamA(int score) {
TextView scoreView = (TextView) findViewById(R.id.Team_A_Score);
scoreView.setText(String.valueOf(scoreTeamA));

solved Using Android Studio, how can I create a value which will increase its value by 1 every time a button is clicked? [closed]
