我試圖捕捉WebView的onTouchEvent，以便處理像 MotionEvent.ACTION_UP,MOVE和CANCEL這樣的操作。我做了一個簡單的例子，但沒有成功，但是我只用View來成功。我錯過了什麼嗎？webView onTouchEvent
感謝
public class HelloWebView extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(new MyWebView(this));
}
private static class MyWebView extends WebView {
@Override
public boolean onTouchEvent(MotionEvent event) {
int action = event.getAction();
Log.w("TouchEvent","Touch" + action);
Log.w("HitResult",this.getHitTestResult().toString());
switch (action) {
case (MotionEvent.ACTION_DOWN): // Touch screen pressed
break;
case (MotionEvent.ACTION_UP): // Touch screen touch ended
break;
case (MotionEvent.ACTION_MOVE): // Contact has moved across screen
break;
case (MotionEvent.ACTION_CANCEL): // Touch event cancelled
break;
}
return super.onTouchEvent(event);
}
public MyWebView(Context context) {
super(context);
this.getSettings().setJavaScriptEnabled(true);
this.loadUrl("http://www.google.com");
}
}
}
