我知道他們是類似的問題，但我不能讓他們的工作。我有一個列表片段，其中包含我的數組列表中的項目以及它旁邊的按鈕，用於數組列表中的每個元素。我的最終目標是讓程序只在用戶點擊按鈕時才作出響應，但我甚至無法檢測到屏幕上的點擊。我也嘗試將按鈕的焦點設置爲false（從其他問題中提出），但這也不起作用。這是我的代碼。自定義列表片段禁用點擊元素和啓用按鈕點擊（Android Studio）
public class ResultListFragment extends ListFragment {
private List<String> listValues, keyValues;
private String email, username;
private ArrayAdapter<String> myAdapter;
private ListView myListView;
private TextView title;
@Override
public View onCreateView(LayoutInflater inflater,
ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_resultlist, container, false);
return view;
}
@Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
View v = getView();
myListView = getListView();
listValues = new ArrayList<String>();
myAdapter = new ArrayAdapter<String>(getActivity().getApplicationContext(),
R.layout.fragment_rowlayout, R.id.myListText, CameraActivity.resultList);
setListAdapter(myAdapter);
myAdapter.notifyDataSetChanged();
}
@Override
public void onListItemClick(ListView l, View v, final int position, long id) {
super.onListItemClick(l, v, position, id);
Log.d("blabla", "onListItemClick: clicked to : "+position);
final String delete=CameraActivity.resultList.get(position);
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
builder.setCancelable(true);
builder.setTitle("DELETION");
builder.setMessage(delete + " delete it.");
builder.setPositiveButton("Onayla",
new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
Toast.makeText(getActivity().getApplicationContext(), delete+ "has been deleted", Toast.LENGTH_SHORT).show();
CameraActivity.resultList.remove(position);
myAdapter.notifyDataSetChanged();
for(String st:CameraActivity.resultList){
Log.d("TAG", "onClick: eleman: " +st);
}
}
});
builder.setNegativeButton(android.R.string.cancel, new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
}
});
AlertDialog dialog = builder.create();
dialog.show();
}
}
