我已经为我的游戏添加了一个计时器但是这样做我一直得到错误“类型View中的方法setOnTouchListener(View.OnTouchListener)不适用于参数(scene5.MyCountDownTimer)”我似乎无法修理它。这可能只是我犯了一个简单的错误,但任何解决方案都会很棒。错误大约是我的代码的一半,我用//标记了这是我的问题区!干杯球员

答案 0 :(得分:2)
你的问题在这里:
public class scene5 extends Activity implements OnClickListener, OnTouchListener {
...
@Override
public boolean onTouch(View v, MotionEvent event) {
...
}
}
您还必须实现 OnTouchListener 。
答案 1 :(得分:0)
使用
scene5.this
而不是
答案 2 :(得分:-1)
问题是iv.setOnTouchListener (this);
您传递的this
上下文属于计时器任务,您需要使用iv.setOnTouchListener (scene5.this);
此外,我认为您需要在ImageView
本身中找到onCreate
引用。您目前正在做的事情ImageView iv = (ImageView) findViewById (R.id.image);
将无效。
