我正在開發一個android應用程序,在那裏我使用ViewPager的fakedrag創建圖像幻燈片。默認情況下,ontouch會被禁用。我會在觸摸時停止拖動過程。我嘗試以下方式聯繫,停止fakedrag觸摸android
@Override
public boolean onTouch(View v, MotionEvent event)
{
if(_mViewPager.getId() == v.getId())
{
if(event.getAction() == MotionEvent.ACTION_DOWN)
{
_mViewPager.beginFakeDrag();
_mViewPager.endFakeDrag();
}
}
return false;
}
但是,上面的代碼給出了一個合力。請看下面的錯誤日誌,
