アプリケーションで関数「setOnItemLongClickListener」を実行できません。お願い助けて。どうすればそれができますか？私はポケットベルとページアダプタを持っています
pager = (ViewPager) findViewById(R.id.pager);
Log.d(Tag,"pager 2");
pagerAdapter = new MyFragmentPagerAdapter(getSupportFragmentManager());
Log.d(Tag,"pager 3");
pager.setOffscreenPageLimit(0);
pager.setAdapter(pagerAdapter);
Log.d(Tag,"pager 4");
setListTitle(0);
pager.setOnPageChangeListener(new OnPageChangeListener() {
@Override
public void onPageSelected(int position) {
Log.d(Tag,"ПЕРЕЛИСТНУЛИ СТРАНИЦУ");
//pager.invalidate();
setNameList(position);
//****
}
@Override
public void onPageScrolled(int position, float positionOffset,
int positionOffsetPixels) {
}
@Override
public void onPageScrollStateChanged(int state) {

これは MyFragmentPagerAdapter です

OnLongClick は、MySqlCursorAdapter の関数で動作します。しかし、setOnItemLongClickListener が必要です。MainActivity でこの機能を実行してみます
ListView lvTareas = (ListView) findViewById (R.id.list);
lvTareas.setOnItemLongClickListener(new OnItemLongClickListener() {
@Override
public boolean onItemLongClick(AdapterView<?> arg0, View arg1,
int pos, long id) {
Log.d(Tag,"pos"+" "+pos);
return true;
}
});
しかし、うまくいきません。お願い助けて？私が正しくないことは何ですか？
