我正在进行2D游戏,我想添加一个主菜单。目前,当我运行我的代码时,我的主要活动开始游戏循环。

public class MainActivity extends Activity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    // Set fullscreen
    this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
            WindowManager.LayoutParams.FLAG_FULLSCREEN);

    // Set No Title
    this.requestWindowFeature(Window.FEATURE_NO_TITLE);


    this.setContentView(new GameSurface(this));
}

这是我的代码,我打算将setContentView()绑定到菜单中的播放按钮。实现我的菜单的最佳方法是什么,将其设置为不同的活动并在创建时加载它,然后通过意图将GameSurface的加载设置为另一个活动或者有更好的方法?

将MainActivity设为主菜单,并创建单独的GameActivity。 例如:

你的main_activity.xml(菜单):

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    android:gravity="center_horizontal"
    android:background="@color/colorAccent"> <!-- define your custom background, f.e. html animation or picture -->

<Button
        android:id="@+id/start_game"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Start the game"
        android:layout_marginTop="30dp" />

<Button
        android:id="@+id/settings"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Settings"
        android:layout_marginTop="30dp" />

<Button
        android:id="@+id/exit"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Exit"
        android:layout_marginTop="30dp" />

您的MainActivity(如果需要,您可以播放音乐或执行其他有用的操作):

public class MainActivity extends AppCompatActivity {

private Button startGame;
private Button settings;
private Button exit;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    startGame = (Button) findViewById(R.id.start_game);
    startGame.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            Intent game = new Intent(MainActivity.this, GameActivity.class);
            startActivity(game);
        }
    });

    settings = (Button) findViewById(R.id.settings);
    settings.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            Intent game = new Intent(MainActivity.this, SettingsActivity.class); 
            startActivity(game);
        }
    });

    exit = (Button) findViewById(R.id.exit);
    exit.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            finish();
            System.exit(0);
        }
    });
}
}

你的GameActivity:

public class GameActivity extends Activity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    // Set fullscreen
    this.getWindow().setFlags(
        WindowManager.LayoutParams.FLAG_FULLSCREEN,
        WindowManager.LayoutParams.FLAG_FULLSCREEN);

    // Set No Title
    this.requestWindowFeature(Window.FEATURE_NO_TITLE);


    this.setContentView(new GameSurface(this));
}
