我写了简单的 ListView 但我有问题，当我从我的列表视图中选择一些项目时我想选中文本但它不起作用我不知道为什么当我从 listView.setOnItemSelectedListener(new OnItemSelectedListener () 到 listView.setOnItemClickListener(new OnItemClickListener() 当我单击时它可以正常工作，但我只希望这个用于选择。这是我的代码：

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_settings);
    List<HashMap<String, String>> aList = new ArrayList<HashMap<String, String>>();
    for (int i = 0; i < 7; ++i) {
        HashMap<String, String> hm = new HashMap<String, String>();
        hm.put("firstLine", menu[i]);
        hm.put("secondLine", submenu[i]);
        hm.put("icon", Integer.toString(ikons[i]));
        aList.add(hm);
    }
    String[] from = { "icon", "firstLine", "secondLine" };
    int[] to = { R.id.icon, R.id.firstLine, R.id.secondLine };
    SimpleAdapter adapter = new SimpleAdapter(getBaseContext(), aList,
            R.layout.alarm_row, from, to);
    ListView listView = (ListView) findViewById(R.id.list);
    listView.setAdapter(adapter);

    listView.setOnItemSelectedListener(new OnItemSelectedListener() {

        @Override
        public void onItemSelected(AdapterView<?> arg0, View view,
                int arg2, long arg3) {
            TextView t = (TextView) view.findViewById(R.id.secondLine);
            t.setSelected(true);
        }

        @Override
        public void onNothingSelected(AdapterView<?> arg0) {
            // TODO Auto-generated method stub

        }
    });

    listView.setOnItemClickListener(new OnItemClickListener() {

        @Override
        public void onItemClick(AdapterView<?> arg0, View view, int arg2,
                long arg3) {
            // TODO Auto-generated method stub
            /*
             * TextView t = (TextView) view.findViewById(R.id.secondLine);
             * t.setFocusable(true); t.setSelected(true);
             */
        }
    });
}

XML： 

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/panel1"
    android:layout_width="fill_parent"
    android:layout_height="?android:attr/listPreferredItemHeight"
    android:background="@drawable/listview_bg"
    android:padding="6dip" >

    <ImageView
        android:id="@+id/icon"
        android:layout_width="wrap_content"
        android:layout_height="fill_parent"
        android:layout_alignBottom="@+id/secondLine"
        android:layout_alignParentTop="true"
        android:scaleType="center"
        android:src="@drawable/alarm_icon" />

    <TextView
        android:id="@+id/secondLine"
        android:layout_width="fill_parent"
        android:layout_height="26dip"
        android:layout_alignParentBottom="true"
        android:layout_alignParentRight="true"
        android:layout_toRightOf="@id/icon"
        android:ellipsize="marquee"
        android:marqueeRepeatLimit="marquee_forever"
        android:paddingLeft="15dip"
        android:paddingRight="15dip"
        android:scrollHorizontally="true"
        android:singleLine="true"
        android:text="Alarm" />

    <TextView
        android:id="@+id/firstLine"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_above="@id/secondLine"
        android:layout_alignParentRight="true"
        android:layout_alignParentTop="true"
        android:layout_alignWithParentIfMissing="true"
        android:layout_toRightOf="@id/icon"
        android:ellipsize="marquee"
        android:marqueeRepeatLimit="marquee_forever"
        android:paddingLeft="15dip"
        android:paddingRight="15dip"
        android:scrollHorizontally="true"
        android:singleLine="true"
        android:text="Ustawienia Alarmu" />

</RelativeLayout>

我认为这应该可行，我不知道出了什么问题，我将非常感谢您的帮助。

在onItemSelected

您应该定义一个自定义适配器，它扩展例如BaseAdapter或您喜欢的适配器，然后添加t.setSelected(true)该getView方法：

@Override
public View getView(int position, View convertView, ViewGroup parent) {
   View view = convertView;
   if (convertView == null)
    view = inflater.inflate(R.layout.row, null);

   TextView t = (TextView) view.findViewById(R.id.secondLine);
   text2.setSelected(true);
   return view;
}
