基础适配器。如何？我在一个 LinearLayout 中有多个 ListView

Question

我有一个简单的布局文件，它显示图标和一些文本视图，然后是一个使用一些字符串数据填充的 ListView。

我使用 ArrayAdapter 使用 android.R.layout.simple_list_item_multiple_choice 填充 ListView，但这给了我 android 的复选框。在这里，我想使用我自己的复选框图像（检查和项目符号，如 hte 图像所示）。

我尝试使用 ApiDemos Lists14.java 示例中的 BaseAdapter 示例，但我仍在努力获取图像或文本。

知道如何覆盖 getView 方法吗？

我的布局 xml 是

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="wrap_content">

感谢您的帮助。谢谢。

创建一个自定义适配器并使用以下代码..

Main.xml

<TextView android:background="@drawable/header_textbg" android:textSize="15sp"  android:paddingTop="2dip"
    android:paddingLeft="12dip" android:textColor="@color/white" android:id="@+id/list_label"
    android:layout_width="fill_parent" android:layout_height="30dip" android:layout_marginTop="5dip"
    android:text="Credit Cards" style="?android:attr/listSeparatorTextViewStyle" />

<ListView android:id="@+id/usercards" android:listSelector="@drawable/list1" 
    android:cacheColorHint="#00000000" android:layout_width="fill_parent" 
    android:layout_height="fill_parent" />        

list.xml

<LinearLayout   xmlns:android="http://schemas.android.com/apk/res/android"
 android:layout_width="fill_parent"
  android:layout_height="wrap_content">
 <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
      android:orientation="vertical" android:layout_width="fill_parent"
      android:layout_height="fill_parent" android:layout_marginLeft="10dip"       android:id="@+id/lay_txt">
     <TextView android:id="@+id/credit_card_listtext" android:textSize="15sp"
          android:textColor="@color/black"
          android:layout_width="wrap_content" android:layout_height="20dip"
          android:ellipsize="end" android:layout_marginTop="15dip" android:text="Card  No" />
      <RadioButton android:id="@+id/select_card" android:layout_width="wrap_content" 
                   android:layout_height="wrap_content"     android:layout_alignParentRight="true"
                 android:focusable="false"/>
</RelativeLayout>

YourActivity.java

  public void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);
    requestWindowFeature(Window.FEATURE_CUSTOM_TITLE);
    setContentView(R.layout.main);
    credit_card_list = (ListView) findViewById(R.id.usercards);
    //Create a custom Adapter here and set adapter here..
    }

您的自定义适配器的 getView 应该是这样的

        public View getView(final int position, View convertView, ViewGroup arg2) {

        if (convertView == null) {
            convertView = mInflater.inflate(R.layout.list,
                    null);
            holder = new ViewHolder();
            holder.text = (TextView) convertView
                    .findViewById(R.id.credit_card_listtext);
            holder.rb = (RadioButton) convertView
                    .findViewById(R.id.select_card);
            convertView.setTag(holder);
        } else {
            holder.text = (TextView) convertView
                    .findViewById(R.id.credit_card_listtext);
            holder.rb = (RadioButton) convertView
                    .findViewById(R.id.select_card);
        }
        holder.text.setText("Array[position]");

       // this is for selecting only one value from all list in Radio button

       holder.rb.setOnCheckedChangeListener(new OnCheckedChangeListener() {
            @Override
            public void onCheckedChanged(CompoundButton buttonView,
                    boolean isChecked) {
                // TODO Auto-generated method stub
                holder.rb.clearAnimation();
            }
        });

        credit_card_list
                .setOnItemClickListener(new AdapterView.OnItemClickListener() {
                    public void onItemClick(AdapterView<?> list, View v,
                            int pos, long id) {
                        //for list click
                                              //some code
                    }
                });
        return convertView;
    }

它包括一个文本视图和一个添加你想要的单选按钮..

对于单选按钮控件，请检查 this 和 this
