錯在剛剛的
*MainActivity*
mView = new MainActivityView(this);
setContentView(mView);
讀不到
MainActivityView裡的東西

*MainActivityView*

複製代碼

至於下面這個等上面的讀到後這也會起作用

public boolean onTouchEvent(MotionEvent event){
if(event.getAction() == MotionEvent.ACTION_DOWN)
mView.myTouchPoint(event.getX(),event.getY());
return super.onTrackballEvent(event);
}
}

複製代碼

我是用onDraw來寫我還不會用surfaceView @@手上有的資料能用都用了還是不太懂

試試看 override onDraw

那是啥麼0.0? 我得到的教材手上的話圖程式只有onDraw跟surfaceView.....

@Override
  public void onDraw(Canvas canvas)
  {
   Super.onDraw(canvas);
...

那東西不是只讓他起作用嗎?

東西可以用了謝謝
