我在游戏中遇到以下问题：
假设我在 lvl 3 上有 5 个屏幕。每个屏幕都有自己的类。所以我有 5 个班级，名为 lvl 3_1_0、3_2_0 .... .... 3_5_0。我还有一个手势监听器，所以当你向右滑动时，它会转到右侧的屏幕。正常玩时一切正常，但如果用户开始疯狂地向右滑动，并且他每秒刷了很多次，游戏就会崩溃。
我想过添加一个“Thread.sleep”，但是当我让线程睡眠时我无法让它工作，加载类时游戏崩溃。我想我把它放在了错误的地方，或地方....如果手势监听器等待一秒钟才能激活，最好的办法是。我还有一个手势过滤器类。我不知道是否应该将 thread.sleep 放入手势过滤器类或每个类中的手势侦听器中。
这是 on create 和手势监听器的代码...
public class lvl3_5_0 extends Activity implements View.OnTouchListener , SimpleGestureListener {
public static final String PREFS_NAME = "MyPrefsFile";
static SharedPreferences settings;
SharedPreferences.Editor editor;
private SimpleGestureFilter detector;
static final int MIN_DISTANCE = 100;
@Override
public void onCreate(Bundle savedInstanceState) {
overridePendingTransition(R.anim.fadein, R.anim.fadeout);
detector = new SimpleGestureFilter(this,this);
super.onCreate(savedInstanceState);
setContentView(R.layout.lvl3_5_0);
ImageView iv = (ImageView) findViewById (R.id.image);
if (iv != null) {
iv.setOnTouchListener (this);
}
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
}
//-----------------------------
// Gesture detection
@Override
public boolean dispatchTouchEvent(MotionEvent me){
this.detector.onTouchEvent(me);
return super.dispatchTouchEvent(me);
}
@Override
public void onSwipe(int direction) {
switch (direction) {
case SimpleGestureFilter.SWIPE_RIGHT : {
{ Intent game = new Intent(lvl3_5_0.this, lvl3_4_0.class);
game.setFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP); game.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
mHandler.removeCallbacks(dismissPopup);
this.finish(); startActivity(game);
}break;}
case SimpleGestureFilter.SWIPE_LEFT :{
{ Intent game = new Intent(lvl3_5_0.this, lvl3_1_0.class);
game.setFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP); game.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
mHandler.removeCallbacks(dismissPopup);
this.finish(); startActivity(game);
}break;}
case SimpleGestureFilter.SWIPE_DOWN : {
break;}
case SimpleGestureFilter.SWIPE_UP :{
openOptionsMenu(); ;
}
break;
}
}
这是我的手势过滤器类
public class SimpleGestureFilter extends SimpleOnGestureListener{
public final static int SWIPE_UP = 1;
public final static int SWIPE_DOWN = 2;
public final static int SWIPE_LEFT = 3;
public final static int SWIPE_RIGHT = 4;
public final static int MODE_TRANSPARENT = 0;
public final static int MODE_SOLID = 1;
public final static int MODE_DYNAMIC = 2;
private final static int ACTION_FAKE = -13; //just an unlikely number
private int swipe_Min_Distance = 65;
private int swipe_Max_Distance = 1111100;
private int swipe_Min_Velocity = 60;
private int mode = MODE_DYNAMIC;
private boolean running = true;
private boolean tapIndicator = false;
private Activity context;
private GestureDetector detector;
private SimpleGestureListener listener;
public SimpleGestureFilter(Activity context,SimpleGestureListener sgl) {
this.context = context;
this.detector = new GestureDetector(context, this);
this.listener = sgl;
}
public void onTouchEvent(MotionEvent event){
if(!this.running)
return;
boolean result = this.detector.onTouchEvent(event);
if(this.mode == MODE_SOLID)
event.setAction(MotionEvent.ACTION_CANCEL);
else if (this.mode == MODE_DYNAMIC) {
if(event.getAction() == ACTION_FAKE)
event.setAction(MotionEvent.ACTION_UP);
else if (result)
event.setAction(MotionEvent.ACTION_CANCEL);
else if(this.tapIndicator){
event.setAction(MotionEvent.ACTION_DOWN);
this.tapIndicator = false;
}
}
//else just do nothing, it's Transparent
}
public void setMode(int m){
this.mode = m;
}
public int getMode(){
return this.mode;
}
public void setEnabled(boolean status){
this.running = status;
}
public void setSwipeMaxDistance(int distance){
this.swipe_Max_Distance = distance;
}
public void setSwipeMinDistance(int distance){
this.swipe_Min_Distance = distance;
}
public void setSwipeMinVelocity(int distance){
this.swipe_Min_Velocity = distance;
}
public int getSwipeMaxDistance(){
return this.swipe_Max_Distance;
}
public int getSwipeMinDistance(){
return this.swipe_Min_Distance;
}
public int getSwipeMinVelocity(){
return this.swipe_Min_Velocity;
}
@Override
public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX,
float velocityY) {
final float xDistance = Math.abs(e1.getX() - e2.getX());
final float yDistance = Math.abs(e1.getY() - e2.getY());
if(xDistance > this.swipe_Max_Distance || yDistance > this.swipe_Max_Distance)
return false;
velocityX = Math.abs(velocityX);
velocityY = Math.abs(velocityY);
boolean result = false;
if(velocityX > this.swipe_Min_Velocity && xDistance > this.swipe_Min_Distance){
if(e1.getX() > e2.getX()) // right to left
this.listener.onSwipe(SWIPE_LEFT);
else
this.listener.onSwipe(SWIPE_RIGHT);
result = true;
}
else if(velocityY > this.swipe_Min_Velocity && yDistance > this.swipe_Min_Distance){
if(e1.getY() > e2.getY()) // bottom to up
this.listener.onSwipe(SWIPE_UP);
else
this.listener.onSwipe(SWIPE_DOWN);
result = true;
}
return result;
}
@Override
public boolean onSingleTapUp(MotionEvent e) {
this.tapIndicator = true;
return false;
}
@Override
public boolean onSingleTapConfirmed(MotionEvent arg0) {
if(this.mode == MODE_DYNAMIC){ // we owe an ACTION_UP, so we fake an
arg0.setAction(ACTION_FAKE); //action which will be converted to an ACTION_UP later.
this.context.dispatchTouchEvent(arg0);
}
return false;
}
static interface SimpleGestureListener{
void onSwipe(int direction);
}
}
所以问题是：我应该把“Thread.sleep(1000);”放在哪里？被try/catch包围？（如果那是我必须使用的）
我尝试了很多，但我被卡住了

这是固定的代码
public class lvl3_3_0 extends Activity implements View.OnTouchListener , SimpleGestureListener {
boolean finished = false; // This was added ( no need to explain XD )
private SimpleGestureFilter detector;
static final int MIN_DISTANCE = 100;
// Handler and runnable reference
private PopupWindow popupWindow;
private Handler mHandler = new Handler();
private Runnable dismissPopup = new Runnable() {
public void run() {
if (popupWindow.isShowing())
popupWindow.dismiss();
}
};
@Override
public void onCreate(Bundle savedInstanceState) {{
overridePendingTransition(R.anim.fadein, R.anim.fadeout);
detector = new SimpleGestureFilter(this,this);
settings = getSharedPreferences(PREFS_NAME, 0);
editor = settings.edit();
editor.putString("currentscreen", "com.appsimple.roomdroid.lvl3_3_0");
editor.commit();
super.onCreate(savedInstanceState);
setContentView(R.layout.lvl3_3_0);
ImageView iv = (ImageView) findViewById (R.id.image);
if (iv != null) {
iv.setOnTouchListener (this);
}
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
}
finished = true; // This will make true the boolean after finishing the loading of the activity
}
//-----------------------------
// Gesture detection
@Override
public boolean dispatchTouchEvent(MotionEvent me){
if (!finished){} // This was added to make the gesturelistener not to listen if the activity has not finished loading.
else {
this.detector.onTouchEvent(me);
return super.dispatchTouchEvent(me); }
return false;
}
@Override
public void onSwipe(int direction) {
if (!finished){}
else {
switch (direction) {
case SimpleGestureFilter.SWIPE_RIGHT : {
finished = false; // this wass added after doing the swipe to avoid the gesture listener to have a que of events.
{ Intent game = new Intent(lvl3_3_0.this, lvl3_2_0.class);
game.setFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP); game.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
mHandler.removeCallbacks(dismissPopup);
this.finish(); startActivity(game);
}break;}
case SimpleGestureFilter.SWIPE_LEFT :{
{ finished = false; Intent game = new Intent(lvl3_3_0.this, lvl3_4_0.class);
game.setFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP); game.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);

this.finish(); startActivity(game);
}break;}

希望这可以帮助 ！感谢 AndroidPenguin 的帮助 :)
我正在考虑的另一个解决方案有点滞后，而不是这个好是在手势过滤器类中制作一个 Runnable 来作为一个计时器，每次计时器达到例如 1 秒时，它都会返回“isoktodotheswipe”布尔值，并且每次擦拭了“isoktodotheswipe”布尔值将变为错误......
