Question

我已经在android listview的单选模式中实现了一个带有复选框的自定义列表视图。我想要一个功能，当我点击复选框时，必须添加与该复选框对应的行（或者说是＆＃ 34; Person＆＃34;该行中显示的对象应该被添加到另一个列表并从该列表中删除）并且在listview上的listview上应该将我带到android中的另一个屏幕。我尝试了其他方式，但是他们指定了复选框需要是可伪装的：false。我也希望点击监听器只在复选框上工作。请提出任何建议或帮助。谢谢提前

这是xml代码。

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >

    <CheckBox
        android:id="@+id/projects_check"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentLeft="true"
        android:layout_alignParentStart="true"
        android:layout_alignParentTop="true"
        android:layout_marginBottom="5dp"
        android:layout_marginLeft="5dp"
        android:layout_marginStart="5dp"
        android:layout_marginTop="5dp"
        android:focusable="false" />

    <TextView
        android:id="@+id/project_name"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignBaseline="@+id/projects_check"
        android:layout_alignBottom="@+id/projects_check"
        android:layout_marginLeft="10dp"
        android:layout_marginStart="10dp"
        android:layout_toEndOf="@+id/projects_check"
        android:layout_toRightOf="@+id/projects_check"
        android:text="TextView" />

</RelativeLayout>

这是我的onitem点击监听器代码..

@Override
    public void onItemClick(AdapterView<?> parent, View view, int position,
            long arg3) {
        Projects info = (Projects) parent.getItemAtPosition(position);
        info.toggleChecked();
        ProjectsHolder viewHolder = (ProjectsHolder) view.getTag();
        viewHolder.getmChoiceSelect().setChecked(info.isChecked());
        if (viewHolder.getmChoiceSelect().isChecked()) {
            completed_projects.add(info);
            mCompProjAdapter.notifyDataSetChanged();
            projects_list.remove(info);
            mProjAdapter.notifyDataSetChanged();
        }
    }

要管理点击行本身，您只需为listView本身编写侦听器即可。这就是我管理复选框点击的方式。

 class CustomAdapter extends ArrayAdapter<BeanClass> {

            private ArrayList<BeanClass> items;

            public FieldPlannedAdapter(Context context,
                    ArrayList<BeanClass> items) {
                super(context, R.layout.custom_list_row, items);

                this.items = items;
            }

            public class ViewHolder {

                protected CheckBox checkbox;
                protected TextView name;

            }

            @Override
            public View getView(final int position, View convertView,
                    ViewGroup parent) {

                final ViewHolder viewHolder;

                if (convertView == null) {

                    LayoutInflater inflater = (LayoutInflater) getActivity()
                            .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
                    convertView = inflater.inflate(R.layout.custom_list_row,
                            null);
                    viewHolder = new ViewHolder();
                    viewHolder.checkbox = (CheckBox) convertView
                            .findViewById(R.id.checkIsMissed);

                    viewHolder.name = (TextView) convertView
                            .findViewById(R.id.txtViewMTPname);


                    convertView.setTag(viewHolder);


                    viewHolder.checkbox
                            .setOnClickListener(new View.OnClickListener() {
                                public void onClick(View v) {
                                    final CheckBox cb = (CheckBox) v;
                                    final BeanClass item = (BeanClass) cb
                                            .getTag();

                                    item.setSelected(cb.isChecked());


                                    if (cb.isChecked()) {
                                        // DO SOMETHING

                                    } else {

                                    }



                                }
                            });


                } else {
                    viewHolder = (ViewHolder) convertView.getTag();
                }

                BeanClass item = items.get(position);
                viewHolder.name.setTag(item);

                viewHolder.checkbox.setTag(item);


                viewHolder.name.setText(item.getName());

                viewHolder.checkbox.setChecked(item.isSelected());

                if (viewHolder.checkbox.isChecked()) {
                    // DO SOMETHING

                } else {
                    // DO SOMETHING
                }

                return convertView;
            }
        }

自定义行示例：

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_margin="10dp" >

    <LinearLayout
        android:id="@+id/row"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="@drawable/card_ui"
        android:descendantFocusability="blocksDescendants"
        android:orientation="vertical"
        android:paddingBottom="10dp"
        android:paddingLeft="10dp"
        android:paddingRight="10dp"
        android:paddingTop="10dp" >

        <TextView
            android:id="@+id/txtViewMTPname"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="Customer Name"
            android:textColor="@drawable/text_selector"
            android:textSize="14sp"
            android:textStyle="bold" />

        <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:orientation="horizontal" >

            <TextView
                android:id="@+id/txtViewMtpDarCity"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_weight="2"
                android:text="dgdgdgdg"
                android:textColor="@drawable/text_selector"
                android:textSize="16sp"
                android:textStyle="italic" />

            <CheckBox
                android:id="@+id/checkIsMissed"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_marginRight="5dp"
                android:gravity="center"
                android:text="Missed" />


        </LinearLayout>
    </LinearLayout>

</FrameLayout>
