我正在使用 onlongitemclick 并且可以生成一个对话框来确认删除，但我无法获得 listitem 位置或文本 .
编辑：我无法在public void onClick（DialogInterface dialog，int which）函数中获取selectedValue字符串值 .
lv 是我的 listview 对象
lv.setOnItemLongClickListener(new OnItemLongClickListener()
{
public boolean onItemLongClick(AdapterView<?> arg0, View arg1,int arg2, long arg3)
{
ListView list1 = (ListView) findViewById(android.R.id.list);
final String selectedValue = (String) list1.getItemAtPosition(arg2);
AlertDialog.Builder alertDialog = new AlertDialog.Builder(RecipeList.this);
alertDialog.setTitle("Delete");
alertDialog.setMessage(selectedValue);
alertDialog.setNegativeButton("Delete", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
obj Recipe = new obj(selectedValue, RecipeList.this);
Recipe.remove(<I need the listview item to create the object and then delete some listing in the DB, seletecValue should do this, but it does not>)
Intent intent2 = new Intent(RecipeList.this, RecipeList.class); //go to recipe list
startActivity(intent2);
} });
alertDialog.setPositiveButton("Keep", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
// alertDialog.dismiss();
} });
alertDialog.show();
return true;
}
});

arg1是您的视图，您应该能够从视图中获取文本 .arg2是该职位 .见：http://developer.android.com/reference/android/widget/AdapterView.OnItemLongClickListener.html
