我必須爲項目做一個列表。這裏是我的XML佈局:Android listview高亮顯示問題
<?xml version="1.0" encoding="utf-8"?>
<TableLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:gravity="center_horizontal"
android:background="#FFFFFF"
android:stretchColumns="0">
<TableRow
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_gravity="center_horizontal"
android:id="@+id/listbox">
<LinearLayout
android:layout_width="fill_parent"
android:background="#FFFFFF"
android:layout_gravity="center_horizontal"
android:layout_height="fill_parent">
<ListView
android:id="@+id/android:list"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
</ListView>
<LinearLayout
android:id="@android:id/empty"
android:layout_width="fill_parent"
android:background="#FFFFFF"
android:layout_gravity="center"
android:layout_height="fill_parent">
<TextView
android:id="@+id/emptytext"
android:paddingTop="100dp"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:textColor="#818185"
android:textSize="25sp"
android:textStyle="bold"
android:background="#FFFFFF"
android:text="@string/empty_fav"
android:gravity="center_horizontal|center_vertical"
android:paddingLeft="6dip"
/>
</LinearLayout>
</LinearLayout>
</TableRow>
</TableLayout>
這是R.layout.custom_list_item_1的xml。
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@android:id/text1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:textColor="#000000"
android:textSize="18sp"
android:textStyle="bold"
android:background="#FFFFFF"
android:textAppearance="?android:attr/textAppearanceLarge"
android:gravity="center_vertical"
android:paddingLeft="6dip"
android:minHeight="?android:attr/listPreferredItemHeight"
/>
這裏是我的代碼。
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.fav_layout);
....
........
wordDataHelper = new WordDataHelper(getApplicationContext());
favCursor = wordDataHelper.getCursorFav();
startManagingCursor(favCursor);
favAdapter = new SimpleCursorAdapter(
this,
R.layout.custom_list_item_1,
favCursor,
new String[] {WordDataHelper.ENGWORD},
new int[] {android.R.id.text1});
setListAdapter(favAdapter);
list = getListView();
list.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position,
long id) {
// TODO Auto-generated method stub
showVideo(((TextView) view).getText());
}});
list.setOnCreateContextMenuListener(new OnCreateContextMenuListener() {
// @Override
public void onCreateContextMenu(ContextMenu menu, View v,
ContextMenu.ContextMenuInfo menuInfo) {
menu.setHeaderTitle("Context Menu");
menu.add(0, CONTEXT_DELETE, 1, "Delete Item");
}
});
list.setTextFilterEnabled(true);
list.setClickable(true);
}
現在一切都顯示正常,所有其他功能也是 工作正常。但是,如果我觸摸任何一行,則不突出顯示 ,即顏色不變。我的代碼中是否有任何問題或 是否必須單獨實施?如果是這樣,怎麼樣?
