我现在需要做的是每当用户触摸列表视图中的某个项目时，该项目将从当前列表视图中删除，并将显示在另一个列表视图中。

这是我的活动：

private ListView mListApplication_kid, mListApplication_non_kid;
private List<ResolveInfo> mListAplicationInfo;
private List<MyApplication> mListApplicationList = new ArrayList<MyApplication>();
private List<MyApplication> mListApplicationList_non_kid = new ArrayList<MyApplication>();
private KidModeAdapter1 mAplicationAdapter;
private KidModeAdapter2 mAplicationAdapter_non_default;
private Context mContext;
private String TAG = "KidModeActivity";

@Override
protected void onCreate(Bundle arg0) {
    // TODO Auto-generated method stub
    super.onCreate(arg0);
    setContentView(R.layout.activity_kid_mode);
    mContext=this;
    list_kid_mode =  new ArrayList<String>(Arrays.asList(PHONE, CONTACTS, MESSAGE, CAMERA, CHROME));
    mListApplication_kid = (ListView) findViewById(R.id.listview_kidmode_default);
    mListApplication_non_kid = (ListView) findViewById(R.id.listview_kidmode_non_default);
    loadAplication();
}
private void loadAplication() {
    mAplicationAdapter = new KidModeAdapter1(mContext, R.layout.aplication_item, mListApplicationList);
    mAplicationAdapter_non_default = new KidModeAdapter2(mContext, R.layout.aplication_item, mListApplicationList_non_kid);
    mListApplicationList.removeAll(mListApplicationList);
    mListApplicationList_non_kid.removeAll(mListApplicationList_non_kid);
    mAplicationAdapter.notifyDataSetChanged();
    mAplicationAdapter_non_default.notifyDataSetChanged();
    new loadKidMode().execute(); // load all the available MyApplication into the mListApplicationList, and mListApplicationList_non_kid
    mListApplication_kid.setAdapter(mAplicationAdapter);
    mListApplication_non_kid.setAdapter(mAplicationAdapter_non_default);
}

这是我的xml文件：

<?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="match_parent"
android:orientation="vertical" >

<TextView
    android:id="@+id/txtKidMode"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_alignParentLeft="true"
    android:layout_alignParentTop="true"
    android:layout_marginTop="5dp"
    android:gravity="center"
    android:text="@string/default_mode"
    android:textColor="@color/title"
    android:textSize="@dimen/title_textsize" />

<ListView
    android:id="@+id/listview_kidmode_default"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="@color/counter_text_color"
    android:clickable="true">
</ListView>

<ListView
    android:id="@+id/listview_kidmode_non_default"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_marginBottom="10dp"
    android:background="@color/list_background" 
    android:clickable="true">
</ListView>

</LinearLayout>

我知道这是关于此活动并设置KidModeAdapter1和KidModeAdapter2文件，但只是不知道如何。请你帮帮我!!!

您应该将OnItemClickListener设置为您要点击的ListView：

mListApplication_kid.setOnItemClickListener(new OnItemClickListener(){
    @Override
    public void onItemClick(AdapterView<?> parent, View view, int position,
        long id) {

         mListApplicationList_non_kid.add(parent.getItemAtPosition(position));
         mAplicationAdapter_non_default.notifyDataSetChanged();
         mListApplicationList.remove(parent.getItemAtPosition(position));
         mApplicationAdapter.notifyDataSetChanged();

 }
});

这将从一个ListView中删除该项目，并在点击该项目时在另一个ListView中插入相同的项目。

修改

如果您在列表项中有其他请求重点的元素，请向其添加android:focusable="false"

listview android：同时添加和删除项目
