有沒(méi)有人有一個(gè)簡(jiǎn)單的ListActivity示例，該示例在列中顯示Textviews，當(dāng)您從左向右滑動(dòng)時(shí)，會(huì)在新視圖中看到該行？這就是說(shuō)編輯該行的數(shù)據(jù)或顯示該行的更多詳細(xì)信息。請(qǐng)不要引用代碼幕府將軍或其他網(wǎng)站，因?yàn)槲乙呀?jīng)用Google搜索過(guò)，也沒(méi)有看到這個(gè)答案。

這是一個(gè)非常簡(jiǎn)化的版本，它使用兩個(gè)偵聽(tīng)器（onTouch用于滑動(dòng)檢測(cè)，onClickIem用于項(xiàng)目單擊檢測(cè)）使用isSwipe標(biāo)志停止onClickItemListener，直到其確認(rèn)不是滑動(dòng)
在檢測(cè)到點(diǎn)擊
不是第一次刷卡的情況下
listView.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3)
{
if(!isSwipe)
{
adapter.increase(arg2);
adapter.notifyDataSetChanged();
}
}
});
檢測(cè)滑動(dòng)
listView.setOnTouchListener(new OnTouchListener() {
private int action_down_x = 0;
private int action_up_x = 0;
private int difference = 0;
@Override
public boolean onTouch(View v, MotionEvent event) {
switch (event.getAction()) {
case MotionEvent.ACTION_DOWN:
action_down_x = (int) event.getX();
isSwipe=false; //until now
break;
case MotionEvent.ACTION_MOVE:
if(!isSwipe)
{
action_up_x = (int) event.getX();
difference = action_down_x - action_up_x;
if(Math.abs(difference)>50)
{
Log.d("action","action down x: "+action_down_x);
Log.d("action","action up x: "+action_up_x);
Log.d("action","difference: "+difference);
//swipe left or right
if(difference>0){
//swipe left
Log.d("action","swipe left");
adapter.decrease(selectedItem);
adapter.notifyDataSetChanged();
}
else{
//swipe right
Log.d("action","swipe right");
}
isSwipe=true;
}
}
break;
case MotionEvent.ACTION_UP:
Log.d("action", "ACTION_UP - ");
action_down_x = 0;
action_up_x = 0;
difference = 0;
break;
}
return false; //to allow the clicklistener to work after
}
})
