Question

我在我的游戏中使用了surfaceview。当游戏完成后，它将通过此意图自动启动其他活动（得分活动）：

mContext = getContext();
Intent intent = new Intent(mContext, ScoreScreen.class);
mContext.startActivity(intent);

它工作正常，但是当我想关闭那个得分活动然后回到surfaceview（“再试一次”按钮）时有一个问题。

我使用此代码完成分数活动：

tryagain.setOnClickListener(new View.OnClickListener() {
        public void onClick(View v) {
            finish();
        }
    });

但它不想回到surfaceview

帮帮我......

抱歉我的英文不好

这是我的SurfaceviewScreen：

    public class SurfaceScreen extends Activity {
    OurView v;
    int level =1, lives = 3, score=0;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        v = new OurView(this);
        v.setKeepScreenOn(true);
        setContentView(v);
    }

    @Override
    protected void onPause() {
        super.onPause();
        v.pause();
    }

    @Override
    protected void onResume() {
        super.onResume();
        v.resume();
    }

    public class OurView extends SurfaceView implements Runnable {
        Thread t = null;
        SurfaceHolder holder;
        boolean isItOK = false;
        boolean spriteLoaded = false;
        private Context mContext;

        Paint paint = new Paint();

        public OurView(Context context) {
            super(context);
            this.mContext = context;
            mContext = getContext();
            holder = getHolder();
        }

        @Override
        public void run() {
            while (isItOK) {
                if (!holder.getSurface().isValid()) {
                    continue;
                }
                update();
                Canvas c = holder.lockCanvas();
                onDraw(c);
                holder.unlockCanvasAndPost(c);

                try {
                    Thread.sleep(20);
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }
            }
        }

        public void pause() {
            isItOK = false;
            while (true) {
                try {
                    t.join();
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }
                break;
            }
            t = null;
        }

        public void resume() {
            isItOK = true;
            t = new Thread(this);
            t.start();
        }

        protected void update(){
            if(lives<1){
                    Intent i = new Intent(mContext, gameover.class);
                    i.putExtra("msg", "LOSE");
                    mContext.startActivity(i);
            }
            //updating
        }

        @Override
        protected void onDraw(Canvas canvas) {
                //drawing
            }
        }
    }
}

这是我的ScoreScreen代码：

    public class ScoreScreen extends Activity{

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.scorescreen);

        TextView txtResult = (TextView)findViewById(R.id.scorescreen_result);
        Button tryagain = (Button)findViewById(R.id.scorescreen_tryagain);
        Intent i = this.getIntent();
        txtResult.setText(i.getStringExtra("msg"));

        tryagain.setOnClickListener(new View.OnClickListener() {
            public void onClick(View v) {
                finish();
            }
        });
    }
}

据我所知，您应该尝试

ScoreActivity.this.finish();

完成得分活动以返回到surfaceview
