Android 2.3.3

我有一个listview，我正在填充自定义视图。

CustomView - ListView项目

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="60dp" 
    android:orientation="horizontal"
    android:layout_margin="2dp" >

    <ImageView
        android:id="@+id/imgView_addcontact"
        android:layout_width="0dip"
        android:layout_height="wrap_content"
        android:src="@drawable/addcontactsmall2"
        android:layout_weight="0.20"
        android:padding="5dp"
        android:layout_gravity="center" />

    <LinearLayout

        android:layout_gravity="center" >

        <TextView

            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="Contact Name"
            android:textSize="20sp" />

        <TextView

            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="Phone Number"
            android:textSize="16sp" />

    </LinearLayout>

    <CheckBox
        android:id="@+id/chbk_addcontact"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_weight="0.10"
        android:padding="5dp"
        android:layout_gravity="center"
        />

</LinearLayout>

ListView XML :::

         android:text="Your Contacts (Phone + SIM)"
         android:layout_gravity="center"
         android:gravity="center" />


     <ListView
         android:id="@+id/lv_addcontact"
         android:layout_width="match_parent"
         android:layout_height="0dip"
         android:layout_weight="1" >

    </ListView>

     <LinearLayout

         android:orientation="horizontal"
         android:layout_gravity="center"
         android:gravity="center" >

         <Button
             android:id="@+id/btn_addcontact_add"
             android:layout_width="wrap_content"
             android:layout_height="wrap_content"
             android:text="ADD CONTACTS" />

         <Button
             android:id="@+id/btn_addcontact_cancel"
             android:layout_width="wrap_content"
             android:layout_height="wrap_content"
             android:text="CANCEL" />

     </LinearLayout>

      <LinearLayout
         android:layout_width="match_parent"
         android:layout_height="100dp"
         android:orientation="vertical" >

         <TextView
         android:id="@+id/txtViewNavigation"
         android:layout_width="wrap_content"
         android:layout_height="fill_parent"
         android:text="Navigation"
         android:layout_gravity="center"
         android:gravity="center" />

     </LinearLayout>

</LinearLayout>

当我运行应用程序时，自定义视图会填充我需要的所有值，但每个自定义视图占用整个屏幕（列表视图可用的空间）。当我向下滚动时，我可以看到其他行。

代码 - getView（）

@Override
        public View getView(int position, View convertView, ViewGroup parent) {
            // TODO Auto-generated method stub

            // View MyView = convertView;

            ContactViewHolder contactViewHolder;

            if (convertView == null) {

                // Inflate the layout
                LayoutInflater li = getLayoutInflater();
                convertView = li.inflate(
                        R.layout.activity_listview_addcontact_item, null);

                contactViewHolder = new ContactViewHolder();

                contactViewHolder.imgContact = (ImageView) convertView
                        .findViewById(R.id.imgView_addcontact);
                contactViewHolder.txtViewContactName = (TextView) convertView
                        .findViewById(R.id.txtView_addcontact_contactname);
                contactViewHolder.txtViewPhoneNumber = (TextView) convertView
                        .findViewById(R.id.txtview_addcontact_phonenumber);
                contactViewHolder.chbkAddContact = (CheckBox) convertView.findViewById(R.id.chbk_addcontact);

                convertView.setTag(contactViewHolder);
            } else {
                contactViewHolder = (ContactViewHolder) convertView.getTag();
            }

            //while (cur.moveToNext()) {

                cur.moveToPosition(position);

/*
                // Add The Image!!!
                String image = cur
                        .getString(cur
                                .getColumnIndex(ContactsContract.CommonDataKinds.Phone.PHOTO_URI));

                if (image != null) {
                    contactViewHolder.imgContact.setImageURI(Uri.parse(image));
                } else {
                    contactViewHolder.imgContact
                            .setImageResource(R.drawable.addcontactsmall2);
                }
*/

                // Add Contact Name //

                String name = cur
                        .getString(cur
                                .getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));

                if (name != null)
                    contactViewHolder.txtViewContactName.setText(name);
                else
                    contactViewHolder.txtViewContactName.setText("Unknown");


                // Add Phone Number //

                String phoneNumber = cur
                        .getString(cur
                                .getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));

                if (phoneNumber != null)
                    contactViewHolder.txtViewPhoneNumber.setText(phoneNumber);
                else
                    contactViewHolder.txtViewPhoneNumber.setText("Unknown");

                //System.out.println(image + "   " + name + "   " + phoneNumber);

            //}

            return convertView;
        }

        public class ContactViewHolder {
            ImageView imgContact;
            TextView txtViewContactName;
            TextView txtViewPhoneNumber;
            CheckBox chbkAddContact;
        }

Answer 1

在你的适配器的getView方法中，当你扩展listview项时，不要像你在这里那样在父视图中传递null：

convertView = li.inflate(R.layout.activity_listview_addcontact_item, null);

相反，将提供的父视图和false传递给备用重载的inflate方法：

convertView = li.inflate(R.layout.activity_listview_addcontact_item, parent, false);

如果您未传递父项，则不会遵守您在xml布局文件中设置的layout_height值。

customview占据列表视图中的整个屏幕
