我必须列出物品清单。以下是我的布局XML:Android listview突出显示问题,android,listview,highlighting,Android,Listview,Highlighting,我必须列出物品清单。以下是我的布局XML: <?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" andro

它是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"
/>
这是我的密码
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);
}
public void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.fav_layout);
....
........
wordDataHelper=新的wordDataHelper(getApplicationContext());
favCursor=wordDataHelper.getCursorFav();
startManagingCursor(favCursor);
favAdapter=新的SimpleCursorAdapter(
这
R.layout.custom_list_item_1,
费克斯,
新字符串[]{WordDataHelper.ENGWORD},
新的int[]{android.R.id.text1});
setListAdapter(FavaAdapter);
list=getListView();
list.setOnItemClickListener(新的OnItemClickListener(){
@凌驾
public void onItemClick(AdapterView父视图、视图、整型位置、,
长id){
//TODO自动生成的方法存根
showVideo(((TextView)view.getText());
}});
setOnCreateContextMenuListener(新的OnCreateContextMenuListener(){
//@覆盖
public void onCreateContextMenu(ContextMenu,视图v,
ContextMenu.ContextMenuInfo menuInfo){
menu.setHeaderTitle(“上下文菜单”);
添加(0,上下文_删除,1,“删除项”);
}
});
list.setTextFilterEnabled(true);
list.setClickable(true);
}
现在一切都很好,所有其他功能也很好
工作很好。但是,如果我触摸任何一行,它都不会突出显示
i、 颜色没有改变。我的代码或密码有问题吗
是否必须单独实施?如果是,如何设置?您可能需要设置
android:listSelector
属性
检查这个答案,解释得很好
如果这不起作用(我还没有尝试过),请尝试将颜色选择器设置为R.layout.custom_list_item_1中定义的TextView的背景。问题是您正在将默认背景绘制覆盖为纯颜色,而纯颜色不支持状态(单击、聚焦等)。如果您希望背景为白色,最好只使用一个“浅色”Android主题,例如
@Android:style/Theme.light.NoTitleBar
尝试删除TextView项目的背景色:
<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:textAppearance="?android:attr/textAppearanceLarge"
android:gravity="center_vertical"
android:paddingLeft="6dip"
android:minHeight="?android:attr/listPreferredItemHeight"
/>
