setOnTouchListener問題

我添加了一個計時器到我的遊戲，但這樣做我不斷收到錯誤「類型View中的方法setOnTouchListener（View.OnTouchListener）不適用於參數（scene5.MyCountDownTimer）」我不能似乎修復它。這可能只是我犯了一個簡單的錯誤，但任何解決方案都會很棒。該錯誤是關於我的代碼的一半，我已經標記爲/ /這是我的問題區域！乾杯傢伙setOnTouchListener問題

你的問題是在這裏：

public class scene5 extends Activity implements OnClickListener, OnTouchListener { 
    ... 
    @Override 
    public boolean onTouch(View v, MotionEvent event) { 
     ... 
    } 
}

你也OnTouchListener來實現。

感謝JaAd，我覺得有點愚蠢，因爲沒有注意到:)它是漫長的一天。感謝所有解答我問題的人。接受答案。 – user2150591

@ user2150591很高興幫助你，如果它可以幫助你更多，對我來說也是漫長的一天XD！ – JJ86

使用

scene5.this

，而不是這個

問題是iv.setOnTouchListener (this);

的this環境下，你是路過貝羅ngs的計時器任務，您需要使用iv.setOnTouchListener (scene5.this);

此外，我認爲你需要找到onCreate本身ImageView參考。你目前正在做什麼ImageView iv = (ImageView) findViewById (R.id.image);將無法正常工作。
