Question

使用膨胀视图，我正在添加和删除按钮。我正在获取多个视图。onclick按钮仅获取最后一个视图ID。我需要循环获取所有视图ID，但是我无法获取多个添加视图的ID。如何获取多个膨胀视图的ID。 / p>

addBuildingSuper.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {

                            try {

                                    listSupers.setAdapter(sArrayAdapter);
                                }
                            }catch (Exception e){
                                e.printStackTrace();
                            }



                            customSupersLayout.setVisibility(View.VISIBLE);
                        }else {
                            customSupersLayout.setVisibility(View.GONE);
                        }


                    }
                });

                listSupers.setOnItemClickListener(new AdapterView.OnItemClickListener() {
                    @Override
                    public void onItemClick(AdapterView<?> parent, View view, int position, long id) {

                        btnCustomSuper.setText(msupers.get(position));
                        listSupers.setTag(position);
                        JSONObject json = null;
                        try {
                            json = jsonArray1.getJSONObject(position);
                            getSuperId=json.getString("id");
                            superId.add(getSuperId);
                            Log.i("msg","btnCustomSupersID"+superId);
                             jsonObject = jsonArray1.getJSONObject(position);

                               Log.i("msg","listID"+listID);
                        } catch (JSONException e) {
                            e.printStackTrace();
                        }
                        Log.i("msg","btnCustomSupers"+btnCustomSuper.getText().toString());
                            customSupersLayout.setVisibility(View.GONE);




                    }
                });


                layout.addView(addView);
            }
        });

这是膨胀视图的代码

在添加setTag的同时尝试对View使用rootView

addView.setTag(counter);
rootView.addView(addView);

并使用相同的标签获取View。

View addView = rootView.findViewWithTag(counter)

所有视图的计数器都不能相同。

编辑：

仅在获取后删除ImageView：

counter++;
ImageView remove = addView.findViewById(R.id.remove);
remove.setTag("r"+counter);
remove.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    String tag = v.getTag();
                    View viewToRemove = layout.findViewWithTag(tag.replace("r",""));
                    layout.removeView(viewToRemove);
                }
            });

在将addView添加到布局之前，请执行以下操作：

addView.setTag(counter);
layout.addView(addView);

如何获取多个膨胀视图的ID？
