英文:
SetOnClickListener doesn't work in DialogFragment
问题
以下是您要翻译的内容：
我正在尝试在 DialogFragment 内部的 ListView 中单击时获取索引，但是我什么都没有得到... 我不知道为什么...
这是我在其中使用 setOnClickListener 的 OnCreatedDialog：
这是我的适配器，我正在尝试在这里设置 setOnClickListener：
public class AdapterListviewChangeStartingKarateka extends ArrayAdapter {Context context;int item_Layaut;ArrayList<Karateka> data;ApiUtils apiUtils;public AdapterListviewChangeStartingKarateka(Context context, int item_Layaut, ArrayList<Karateka> data) {super(context, item_Layaut,data);this.context = context;this.item_Layaut = item_Layaut;this.data = data;}@NonNull@Overridepublic View getView(final int position, @Nullable View convertView, @NonNull ViewGroup parent) {if (convertView == null) {LayoutInflater layoutInflater = LayoutInflater.from(context);convertView = layoutInflater.inflate(item_Layaut, parent, false);}String image = data.get(position).getPhoto_karateka();ImageView elementImage = convertView.findViewById(R.id.change_starting_picture_karateka);if(image!= null || !image.isEmpty() ) {Picasso.get().load(apiUtils.BASE_URL_PICTURE + image).fit().into(elementImage);} else {elementImage.setImageResource(R.drawable.default_image);}Button buttonToChange= convertView.findViewById(R.id.item_button_to_change);ListView list = convertView.findViewById(R.id.starting_listview);list.setOnItemClickListener(new AdapterView.OnItemClickListener() {@Overridepublic void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {Log.d("indexListview", String.valueOf(i));}});}}
英文:
I am trying to get the index when I click in the listview inside the DialogFragment, but I don't get anything... I don't know why...
This is the OnCreatedDialog where I have the setOnClickListener:
This is my Adapter, I am trying to put the setOnClickListener here:
public class AdapterListviewChangeStartingKarateka extends ArrayAdapter {Context context;int item_Layaut;ArrayList<Karateka> data;ApiUtils apiUtils;public AdapterListviewChangeStartingKarateka(Context context, int item_Layaut, ArrayList<Karateka> data) {super(context, item_Layaut,data);this.context = context;this.item_Layaut = item_Layaut;this.data = data;}@NonNull@Overridepublic View getView(final int position, @Nullable View convertView, @NonNull ViewGroup parent) {if (convertView == null) {LayoutInflater layoutInflater = LayoutInflater.from(context);convertView = layoutInflater.inflate(item_Layaut, parent, false);}String image = data.get(position).getPhoto_karateka();ImageView elementImage = convertView.findViewById(R.id.change_starting_picture_karateka);if(image!= null || !!!image.isEmpty() ) {Picasso.get().load(apiUtils.BASE_URL_PICTURE + image).fit().into(elementImage);}else{ elementImage.setImageResource(R.drawable.default_image); }Button buttonToChange= convertView.findViewById(R.id.item_button_to_change);ListView list = convertView.findViewById(R.id.starting_listview);list.setOnItemClickListener(new AdapterView.OnItemClickListener() {@Overridepublic void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {Log.d("indexListview", String.valueOf(i));}});}

尝试实现一个ListView适配器，并在适配器的getView()方法中定义您的监听器。
您应该为每个视图元素设置监听器。
viewKarateka.setOnClickListener(new View.OnClickListener() {public void onClick(final View v) {Log.d("indexListview", String.valueOf(i));}});
英文:
Try to implement an ListView adapter and define your listener in adapter's getView() method.
You should set listener for each view element.
viewKarateka.setOnClickListener(new View.OnClickListener() {public void onClick(final View v) {Log.d("indexListview", String.valueOf(i));}}
