我知道我的标题很混乱，但不知道如何以最易懂的方式提出这个问题。希望你能理解。如何在玩家输掉时启动“新Game.class”？
在我的比赛有2类
- “mainActivity” 游戏视图。
- “游戏”扩展了SurfaceView并实现了Runnable（游戏循环）。
第一个屏幕显示按钮“开始新游戏”，一旦你点击按钮setContentView替换它的显示视图game.class。
到目前为止一切工作正常。现在，假设玩家输了，我想回到主屏幕，一旦他点击“开始新游戏”游戏，就从头开始。
目前点击返回按钮 “重新从0游戏”
这里是我的课：
MainActivity：
public class MainActivity extends Activity implements OnTouchListener {
DialogPause pauseDialog;
public MyPreferences pref;
private TextView txCoins;
public Game game;
public static Music music;
ViewAnimator viewAnimator;
@SuppressLint("ClickableViewAccessibility")
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
pref = new MyPreferences(this);
music = new Music(this);
pauseDialog = new DialogPause(this);
setContentView(R.layout.menu);
view();
}
public void view(){
txCoins = (TextView)findViewById(R.id.txCoins);
txCoins.setText("Coins "+pref.getInt("coins"));
}
public void newGame(){
if(game != null){
game.destroyed();
}
game = new Game(this);
game.start();
game.setOnTouchListener(this);
setContentView(game);
}
public void click(View v){
newGame();
}
protected void onStart() {
super.onStart();
}
@Override
protected void onStop() {
music.StopBackgroundMusic();
super.onStop();
}
@Override
public void onBackPressed() {
newGame();
}
游戏循环类：
public class Game extends SurfaceView implements Runnable{
public static MyPreferences pref;
public static Levels level;
public static int SCREEN_W;
public static int SCREEN_H;
public static boolean running;
public static boolean pause = false;
private Thread thread = null;
private SurfaceHolder holder;
private Canvas canvas;
private Paint p = new Paint();
public static Handler handler = new Handler();
public static Resources res;
public Timer timer;
public Game(Context context) {
super(context);
res = getResources();
holder = getHolder();
level = new Levels();
timer = new Timer();
pref = new MyPreferences(context);
System.out.println("Create Game instance");
}
public void run() {
init();
long lastTime = System.nanoTime();
double delta = 0;
double ns = 1000000000.0/30.0;
System.out.println("Run method" + running);
//Start looping...
while (running) {
//If it's not pause
long now = System.nanoTime();
delta+=(now - lastTime)/ns;
lastTime = now;
if(!holder.getSurface().isValid()){continue;}
canvas = holder.lockCanvas();
SCREEN_W = canvas.getWidth();
SCREEN_H= canvas.getHeight();
while (delta >-1) {
if(!pause)tick();
delta--;
}
level.level1();
render(canvas);
holder.unlockCanvasAndPost(canvas);
if(ControlPanel.PLAYER_POWER <=0){
System.out.println("Loose!");
ControlPanel.PLAYER_POWER = 100;
stop();
start();
}
}
}
private void render(Canvas c) {
handler.render(c);
textOnScreen(c);
}
public void tick(){
handler.tick();
}
public void init(){
ControlPanel.COINS = pref.getInt("coins");
MainActivity.music.backgroundMusic();
handler.addSpaceShip(new Player(500, 500, 10, 10, handler, Sprite.getSprite(0)));
// handler.addKing(new King(Game.SCREEN_W/2, 100,
// 40, 40, handler, Sprite.getSprite(18), 0));
}
public void start() {
//If the tread are new one
if(thread==null){
thread = new Thread(this);
thread.start();
timer.start();
}
//if it not running
if(!running) {
pause = false;
running =true;
}
}
public void stop() {
pause = true;
running = false;
timer.stop();
pref.putInt("coins", ControlPanel.COINS);
}
public void pause() {
pause = true;
}
public void destroyed() {
System.out.println("Stop");
running = false;
this.stop();
}
public void textOnScreen(Canvas c){
p = new Paint();
p.setColor(Color.YELLOW);
p.setTextSize(50);
c.drawText("POWER = " + ControlPanel.PLAYER_POWER, SCREEN_W/2 ,50 , p);
c.drawText("Time = " + timer.timeFormat(), 100 ,50 , p);
c.drawText("Coins = " + ControlPanel.COINS, 10 ,SCREEN_H - 10 , p);
p.setColor(Color.WHITE);
c.drawText("Bullets = " +ControlPanel.BULLET, SCREEN_W - 390,SCREEN_H - 10 , p);
p.setColor(Color.WHITE);
c.drawText(ControlPanel.Distance + " km ", SCREEN_W /2 - 200,SCREEN_H - 10 , p);
}
}
请帮忙!!我已经过了一周半的时间，并且无法解决它:(（
你能还包括你的布局？还有，你有没有任何理由你没有两个活动inst一个吗？那么，您的MainActivity会包含启动屏幕，而GameActivity会包含实际的游戏？最后，'System.out.println（“Loose！”）;'应该是'System.out.println（“Lost！”）;':) – 2015-03-03 02:41:11
