android checkbox多選框實現

下面是一個在Android ListView中實現多選的例子代碼：

XML布局資源檔
<?xml version="1.0" encoding="utf-8"?><br /><LinearLayout android:id="@+id/LinearLayout01"<br /> android:layout_width="fill_parent" android:layout_height="fill_parent"<br /> xmlns:android="http://schemas.android.com/apk/res/android"><br /> <ListView android:id="@+id/ListView01" android:layout_height="wrap_content"<br /> android:layout_width="fill_parent"><br /> </ListView><br /></LinearLayout>

在Activity中繫結資料行表並顯示：

public class ListViewMultipleChoiceExample extends Activity {<br /> private ListView lView;<br /> private String lv_items[] = { "Android", "iPhone", "BlackBerry",<br />"AndroidPeople", "J2ME", "Listview", "ArrayAdapter", "ListItem",<br />"Us", "UK", "India" };<br /> @Override<br /> public void onCreate(Bundle icicle) {<br /> super.onCreate(icicle);<br /> setContentView(R.layout.main);<br /> lView = (ListView) findViewById(R.id.ListView01);<br /> // Set option as Multiple Choice. So that user can able to select more the one option from list<br /> lView.setAdapter(new ArrayAdapter<String>(this,<br /> android.R.layout.simple_list_item_multiple_choice, lv_items));<br /> lView.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);<br /> }<br />}<br />

 

效果介面如下：

擷取選中的清單項目操作：
lView.setOnItemClickListener(new OnItemClickListener() {<br /> public void onItemClick(AdapterView arg0, View arg1, int arg2,long arg3)<br /> {<br /> List list = new ArrayList();<br /> SparseBooleanArray a = lView.getCheckedItemPositions();<br /> for(int i = 0; i < lv_items.length ; i++)<br /> {<br /> if (a.valueAt(i))<br /> {<br /> Long val = lView.getAdapter().getItemId(a.keyAt(i));<br /> Log.v(TAG, "index=" + val.toString());<br /> list.add(lView.getAdapter().getItemId((a.keyAt(i))));<br /> }<br /> }<br /> }<br />}); // End of Listener
