Question

我使用“lv_del_transl.setChoiceMode（ListView.CHOICE_MODE_MULTIPLE）”来设置此选项。

创建AlertDialog的代码：

Al_tr.setTitle("Title");

RelativeLayout view_T = (RelativeLayout)getLayoutInflater().inflate(R.layout.listofword_cmenu_del_transl, null);
Al_tr.setView(view_T);


TextView del_transl = (TextView)view_T.findViewById(R.id.del_transl);
ListView lv_del_transl = (ListView)view_T.findViewById(R.id.lv_del_transl);
Button del_transl_OK = (Button)view_T.findViewById(R.id.del_transl_OK);
Button del_transl_Cancel = (Button)view_T.findViewById(R.id.del_transl_Cancel);


al_del_tr=Al_tr.create();

Del_transl.setText("word");

Cursor c_adap_tr=cur_del_tr(......);
startManagingCursor(c_adap_tr);

String[] from_r = new String[]{NAME};
int[] to_r = new int[] {R.id.transl };
scAdapter_transl = new SimpleCursorAdapter(this, R.layout.listofword_cmenu_del_transl_item, c_adap_tr, from_r, to_r);
lv_del_transl.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE); // for set Multiple property

lv_del_transl.setAdapter(scAdapter_transl);

del_transl_OK.setOnClickListener(new View.OnClickListener() {

    public void onClick(View v) {
        String sel="0";

        SparseBooleanArray sbArray = lv_del_transl.getCheckedItemPositions();
        for (int i = 0; i < lv_del_transl.getCount(); i++) {

            if (sbArray.get(i))
                sel+=Integer.toString(lv_del_transl.getCheckedItemPosition())+" ";
        }
        Toast.makeText(getApplicationContext(), Integer.toString(lv_del_transl.getCount())+" "+sel, Toast.LENGTH_SHORT).show();


    }
});    
al_del_rt.show();

ListView的Xml文件

 <LinearLayout

        android:layout_width="match_parent"

            android:layout_weight="1"
            android:text="@string/text_del_word_Cancel" />
    </LinearLayout>

</RelativeLayout>

其中listofword_cmenu_del_transl_item.xml

 <?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="wrap_content"
 android:orientation="horizontal">

<TextView
 android:id="@+id/transl"
 android:layout_width="wrap_content"
 android:layout_height="wrap_content"
 android:layout_marginLeft="20dp"
 android:layout_centerVertical="true"
 android:textSize="19sp">
</TextView>

<CheckBox 
android:id="@+id/checbox_id"
android:layout_marginRight="10dp"
android:layout_alignParentRight="true"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>

 </RelativeLayout>

但是SparseBooleanArray sbArray没有效果。我无法定义检查位置。请帮我找个错误。
