私は次のコードを試しました..
btnRemoveItem.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
Bundle b = new Bundle();
b.putLong("index", item.id);
AlertDialog.Builder builder = new AlertDialog.Builder(getApplicationContext());
builder.setTitle("Are you sure you ?");
builder.setMessage("Are you suer you want to remove this item from the cart?");
builder.setPositiveButton("No", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
dialog.cancel();
}
});
builder.setNegativeButton("Yes", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
}
});
Dialog dd= builder.create();
dd.show();
}
});
しかし、私は次のエラーが発生しました..
