How do I check if an ID contains a certain phrase?

I am making a simple app with four scores, each score having an add button and a subtract button. To make code simpler, I named each button's onClick to addScore or subScore. Each button's ID contains something such as android:@+id/team1AddButton. I need to check in the onClick which team is being affected for both onClicks.

The button code is simple (removed most formatting code):

<Button
           android:id="@+id/team1AddButton"
           android:layout_width="55dp"
           android:layout_height="75dp"
           android:text="+"
           android:onClick="addScore" />

<Button
           android:id="@+id/team1SubButton"
           android:layout_width="55dp"
           android:layout_height="75dp"
           android:text="-"
           android:onClick="addScore" />

The Java code is what I'm having trouble with.

public void addScore(View v) {
        if (v.getId().toString().contains("team1"));

    }

Here is what are you looking for:

public void addScore(View v) {
    String resourceName = getResources().getResourceName(v.getId());
    String[] parts = resourceName.split("/");
    String result = parts[parts.length - 1];
    
    if (result.contains("team1")) {
        //..
    }
}

resourceName value will be like: packageName:id/team1AddButton

So if we split the string by "/" and take the last part, we get the result.

or

public void addScore(View v) {
   String resourceName = getResources().getResourceName(v.getId());

   if (resourceName.contains("team1")) {
       //..
   }
}

If exact resourceName doesn't required then just check if contains or not.

Hope it helps!

You can't get view's id with string type.If you call view.getId(),it'll return an Integer value.

try this

if(view.getId() == R.id.team1AddButton){
        
}else if(view.getId() == R.id.team1SubButton){
        
}
