如何将弹出菜单添加到每个项目的自定义列表视图 android
how to add popup menu to custom listview to each item android
我卡在了一点。
我想将弹出菜单添加到自定义列表视图中的每个项目。
我试过了,但它只在最后一个位置或 list.I 的最后一项弹出,我得到了为什么它出现在最后一个位置但没有得到解决方案的原因
我在这里添加适配器 class
public class InterestLevelAdapterEditable extends BaseAdapter {
private Activity activity;
private TextView level;
private InterestLevel m;
private LayoutInflater inflater;
private List<InterestLevel> interestLevelList;
public InterestLevelAdapterEditable(Activity activity, List<InterestLevel> interestLevelList) {
this.activity = activity;
this.interestLevelList = interestLevelList;
}
@Override
public int getCount() {
return interestLevelList.size();
}
@Override
public Object getItem(int location) {
return interestLevelList.get(location);
}
@Override
public long getItemId(int position) {
return position;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
if (inflater == null)
inflater = (LayoutInflater) activity
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
if (convertView == null)
convertView = inflater.inflate(R.layout.interest_level_editable, null);
TextView sports_name = (TextView) convertView.findViewById(R.id.sportsName);
level = (TextView) convertView.findViewById(R.id.level);
m = interestLevelList.get(position);
sports_name.setText(m.getSports_name());
level.setText(m.getLevel());
level.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
//Creating the instance of PopupMenu
PopupMenu popup = new PopupMenu(activity, level);
//Inflating the Popup using xml file
popup.getMenuInflater().inflate(R.menu.popup_level, popup.getMenu());
//registering popup with OnMenuItemClickListener
popup.setOnMenuItemClickListener(new PopupMenu.OnMenuItemClickListener() {
public boolean onMenuItemClick(MenuItem item) {
level.setText(item.getTitle());
return true;
}
});
popup.show();//showing popup menu
}
});
return convertView;
}
}
我得到的理由是我必须在点击侦听器中传递位置但不知道我应该如何添加位置或(具有位置的 InterestLevel 的 m 对象)。

在 setOnClickListener()
之外创建 PopupMenu
并在 onClick()
中创建 show()
:
//Creating the instance of PopupMenu
final PopupMenu popup = new PopupMenu(activity, level);
//Inflating the Popup using xml file
popup.getMenuInflater().inflate(R.menu.popup_level, popup.getMenu());
//registering popup with OnMenuItemClickListener
popup.setOnMenuItemClickListener(new PopupMenu.OnMenuItemClickListener() {
public boolean onMenuItemClick(MenuItem item) {
level.setText(item.getTitle());
return true;
}
});
level.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
popup.show();//showing popup menu
}
});
我需要像列表视图一样的弹出菜单。我尝试了这段代码,它是正确的(reference):
private static final String TITLE = "title";
private static final String ICON = "icon";
private List<HashMap<String, Object>> data = new ArrayList<HashMap<String,
Object>>();
// Use this to add items to the list that the ListPopupWindow will use
private void addItem(String title, int iconResourceId) {
HashMap<String, Object> map = new HashMap<String, Object>();
map.put(TITLE, title);
map.put(ICON, iconResourceId);
data.add(map);
}
// Call this when you want to show the ListPopupWindow
private void showListMenu(View anchor) {
ListPopupWindow popupWindow = new ListPopupWindow(this);
ListAdapter adapter = new SimpleAdapter(
this,
data,
android.R.layout.activity_list_item, // You may want to use your own cool layout
new String[] {TITLE, ICON}, // These are just the keys that the data
uses
new int[] {android.R.id.text1, android.R.id.icon}); // The view ids
to map the data to
popupWindow.setAnchorView(anchor);
popupWindow.setAdapter(adapter);
popupWindow.setWidth(400); // note: don't use pixels, use a dimen resource
popupWindow.setOnItemClickListener(myListener); // the callback for when a list item is selected
popupWindow.show();
}
custom layout and work as listview
