自己折腾了半天,没有搞出来,所以,趁下班之际,提个问题,请大家帮忙解决,感激不尽。想要的效果是:通过单击屏幕,将Gallery控件显示或隐藏,现在的问题是,由于有了ImageSwitcher触摸屏幕切换图片的功能,单击屏幕的事件不知道如何去获取,如果将imageSwitcher.setOnTouchListener(this)语句注释掉,单击屏幕的事件就可以了。可运行的代码如下,图片不好上传哦,麻烦大家自己添加图片,帮忙调试一下,谢谢啦:import android.app.Activity;

解决方案 »

  1.   

    OnClickListener是单击事件的监听接口
      

  2.   

    把onTouch里面的return true;改为return false;
    @Override
        public boolean onTouch(View v, MotionEvent event) {
            
            if (event.getAction() == MotionEvent.ACTION_DOWN)
            {
                downX = (int)event.getX();    // 取得按下时的坐标x
                return false;
            }
            else if (event.getAction() == MotionEvent.ACTION_UP)
            {
                upX = (int)event.getX();    // 取得松开时的坐标x;
                if (upX - downX > 100)
                {
                    // 从左拖到右,即看前一张
                    // 如果是第一,则去到尾部
                    if (gallery.getSelectedItemPosition() == 0)
                        selectedTag = gallery.getCount() - 1;
                    else
                        selectedTag = gallery.getSelectedItemPosition() - 1;
                    
                    imageSwitcher.setInAnimation(AnimationUtils.loadAnimation(this,
                            R.anim.push_right_in));
                    imageSwitcher.setOutAnimation(AnimationUtils.loadAnimation(this, 
                            R.anim.push_right_out));
                }
                else if (downX - upX > 100)
                {
                    // 从右拖到左,即看后一张
                    // 如果是最后,则去到第一
                    if (gallery.getSelectedItemPosition() 
                            == (gallery.getCount() - 1))
                        selectedTag = 0;
                    else
                        selectedTag = gallery.getSelectedItemPosition() + 1;
                    imageSwitcher.setInAnimation(AnimationUtils.loadAnimation(this,
                            R.anim.push_left_in));
                    imageSwitcher.setOutAnimation(AnimationUtils.loadAnimation(this, 
                            R.anim.push_left_out));
                }
                
                // 改变gallery图片所选,自动触发ImageSwitcher的setOnItemSelectedListener
                gallery.setSelection(selectedTag, true);
                return false;
            }
            
            return false;
        }
      

  3.   

      if (upX - downX > 100)
    这些东西你都不加括号的啊
      if ((upX - downX) > 100)
      

  4.   

    谢谢,这个我试过,没用,使得触摸与单击都失效。
    你有这方面的 Demo 吗?
      

  5.   


    还以为你已经加了隐藏显示gallery的代码!将下面代码加到你原来代码:
    upX = (int)event.getX();    // 取得松开时的坐标x;
    的前面
    if(gallery.getVisibility() == 4)
             {
             gallery.setVisibility(0);
             }
             else
             {
             gallery.setVisibility(4);
             }
      

  6.   

    以下是滑动时不处理。else if (event.getAction() == MotionEvent.ACTION_UP)
            {
                upX = (int)event.getX();    // 取得松开时的坐标x;
                if (upX - downX > 100)
                {
                    // 从左拖到右,即看前一张
                    // 如果是第一,则去到尾部
                    if (gallery.getSelectedItemPosition() == 0)
                        selectedTag = gallery.getCount() - 1;
                    else
                        selectedTag = gallery.getSelectedItemPosition() - 1;
                    
                    imageSwitcher.setInAnimation(AnimationUtils.loadAnimation(this,
                            R.anim.push_right_in));
                    imageSwitcher.setOutAnimation(AnimationUtils.loadAnimation(this, 
                            R.anim.push_right_out));
                }
                else if (downX - upX > 100)
                {
                    // 从右拖到左,即看后一张
                    // 如果是最后,则去到第一
                    if (gallery.getSelectedItemPosition() 
                            == (gallery.getCount() - 1))
                        selectedTag = 0;
                    else
                        selectedTag = gallery.getSelectedItemPosition() + 1;
                    imageSwitcher.setInAnimation(AnimationUtils.loadAnimation(this,
                            R.anim.push_left_in));
                    imageSwitcher.setOutAnimation(AnimationUtils.loadAnimation(this, 
                            R.anim.push_left_out));
                }
                else
                {
                 if(gallery.getVisibility() == 4)
                 {
                 gallery.setVisibility(0);
                 }
                 else
                 {
                 gallery.setVisibility(4);
                 }
                }
                
                // 改变gallery图片所选,自动触发ImageSwitcher的setOnItemSelectedListener
                gallery.setSelection(selectedTag, true);
                return true;
            }
