java - : Hand over points to GameOverActivity

Question

我有一个 GameActivity 和一个 GameOverActivity。我将游戏积分保存在 GameActivity 中，但会在 GameOverActivity 中显示这些积分。我必须做什么？ 我的游戏 Activity :

 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);
}
}

您可以使用sharedPreferences全局保存您当前的分数。否则，如果您只想通过 Intent 传递分数，请在目标 Intent 中使用 .GetExtras()
