在finish一个带有自定义SurfaceView的Activity时发生报错
I/ple.planebattl: Thread[6,tid=5848,WaitingInMainSignalCatcherLoop,Thread*=0xe21c1c10,peer=0x13080280,"Signal Catcher"]: reacting to signal 3

以下是最有可能发生错误的地方：
```java
@Override
public void run() {
SurfaceView surfaceView = findViewById(R.id.surfaceView);
surfaceviewwidth=surfaceView.getWidth();
surfaceviewheight=surfaceView.getHeight();
x=surfaceView.getWidth()/2+myplanebit.getWidth();
y=surfaceView.getHeight()-myplanebit.getHeight()-100;
timer = new Timer();
timerTask = new TimerTask() {
@Override
public void run() {
bullet();
}
};
timer.schedule(timerTask,0,300);
timer2 = new Timer();
timerTask2 = new TimerTask() {
@Override
public void run() {
enemy();
}
};
timer2.schedule(timerTask2,500,150);
timer3 = new Timer();
timerTask3 = new TimerTask() {
@Override
public void run() {
boss();
}
};
timer3.schedule(timerTask3,5000);
//背景画布
while (mIsDrawing) {
long start = System.currentTimeMillis();
count++;
if(count>=10000) count = 0;
draw();//draw总方法
long end = System.currentTimeMillis();
if (end - start < 20) {
try {
Thread.sleep(20 - (end - start));
} catch (InterruptedException e) {
e.printStackTrace();
}finally {
if (mCanvas != null){
//释放canvas对象并提交画布
mSurfaceHolder.unlockCanvasAndPost(mCanvas);
}
}
}
}
}
```
