java AS：将点数交给GameOverActivity

Question

我有一个游戏活动和一个游戏过度活动。我在GameActivity中保存了游戏点数，但将在GameActivity中显示这些点数。我该怎么办？ 我的游戏活动：

 public void finishGameActivity(){
    Intent intent = new Intent(this, GameOverActivity.class);
    intent.putExtra("points", points);
    Intent i = getIntent();
    setResult(Activity.RESULT_OK, i);
    finish();
 }

 public void setPoints(){
    points++;
    TextView points_show = (TextView) findViewById(R.id.points);
    points_show.setText("Points: " + points);
}


public class GameOverActivity extends AppCompatActivity {
private int points;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_game_over);
    changeFont();
    TextView points = (TextView) findViewById(R.id.point_stats);
}

private void changeFont(){
    TextView gameover = (TextView) findViewById(R.id.gameover);
    Typeface custom_font = Typeface.createFromAsset(getAssets(),  
"fonts/font.ttf");
    gameover.setTypeface(custom_font);
}
}
