答

首先，您需要使用regex删除 Score:文本:

First, you need to remove the Score : text using regex maybe :

String str = scoreLabel.getText().toString();      
str = str.replaceAll("[^-?0-9]+", "");

然后将其解析为整数:

int total = Integer.parseInt(str);

public class appleTrivia extends AppCompatActivity {

     public int total = 0;
     public int score = 40;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_apple_trivia);


        TextView scoreLabel = (TextView) findViewById(R.id.labelScore);
        scoreLabel.setText("Score: " + score);
        scoreLabel.setText("Score: " + getIntent().getExtras().getInt("points", 0));

        try {
            String str = scoreLabel.getText().toString();      
            str = str.replaceAll("[^-?0-9]+", "");
            total = Integer.parseInt(str);
        }
        catch (NumberFormatException nfe )
        {
        }
    }
        public void onClickProceed (View view) {
        Intent intent = new Intent(this, cherry.class);
        startActivity(intent);
        Toast.makeText(appleTrivia.this, "Your score is:" + total, Toast.LENGTH_LONG).show();
    }
