我正在使用 onlongitemclick 并且可以生成一个对话框来确认删除，但我无法获取 listitem 位置或文本。
编辑:我无法在 public void onClick(DialogInterfacedialog, int which) 函数内获取 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;
}
});
最佳答案
arg1 是您的 View ，您应该能够从 View 中获取文本。
arg2 是位置。
