更改导航抽屉中所选项目的背景颜色

javaandroidandroid-layoutnavigation-drawer

我想要更改导航抽屉中所选项目的蓝色。虽然可以在点击项目时更改颜色，但无法更改活动项目的颜色。这是我使用的代码，在drawable文件夹中：

<selector xmlns:android="http://schemas.android.com/apk/res/android">  
    <item android:state_activated="true" android:drawable="@color/default_color" />
    <item android:state_selected="true" android:drawable="@color/uva_color" />
    <item android:state_pressed="true" android:drawable="@color/uva_color" />
    <item android:state_focused="true" android:drawable="@color/default_color" />
    <item android:drawable="@color/default_color" />  
</selector>

颜色.xml文件
<?xml version="1.0" encoding="utf-8"?>
<resources>
    <color name="uva_color">#f2f8ee</color>
    <color name="default_color">#f2f8ee</color>
</resources>

在导航抽屉的布局中：

<ListView
        android:id="@+id/left_drawer"
        android:layout_width="260dp"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        android:choiceMode="singleChoice"
        android:fitsSystemWindows="true"
        android:clipToPadding="false"
        android:divider="@android:color/transparent"
        android:dividerHeight="0dp"
        android:listSelector="@drawable/activated_background"
        android:background="#ffff"/>

所以，当前选中的项目没有改变颜色..有什么想法吗？

使用Java导航抽屉进行编辑：

private DrawerLayout mDrawerLayout;
private ListView mDrawerList;

actionBar.setCustomView(R.layout.actionbarcustom);
        //actionBar.setDisplayShowTitleEnabled(false);
        //actionBar.setDisplayShowCustomEnabled(true);
setTitle("FTV");
int actionBarTitleId = Resources.getSystem().getIdentifier("action_bar_title", "id", "android");
if (actionBarTitleId > 0) {
    TextView title = (TextView) findViewById(actionBarTitleId);
    if (title != null) {
        title.setTextColor(Color.WHITE);
    }
}

这是我不想要的激活项目中的标准颜色！

看起来不错...

在承载列表视图的Java代码中，调用myListView.setItemChecked(position, true);

另外，你为state_activated设置的颜色与抽屉处于normal状态时的颜色相同。 这是有意为之吗？...

创建一个带有TextView的XML文件

nav_drawer_item.xml

<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android">
    android:id="@+id/textId"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="@drawable/[your_selector]" />

在您的适配器中的getview()函数。
@Override
public View getView(int position, View convertView, ViewGroup parent) { 
    TextView view = (TextView) LayoutInflater.from(getContext()).inflate(R.layout.nav_drawer_item);
    view.setText("whatever_text");
    return view;
}
我已经写了这部分代码：mDrawerList.setItemChecked(possition, true); setTitle(dataList.get(possition).getItemName()); mDrawerLayout.closeDrawer(mDrawerList); 但还是不起作用 :-( - Atlas91
我想要它...我希望激活和选定的颜色是相同的...但现在活动颜色是Android的经典蓝色。 - Atlas91
将 <item android:state_activated="true" android:drawable="@color/default_color" 改为 <item android:state_activated="true" android:drawable="@color/uva_color"。请展示您当前的代码和您想要实现的效果的图片。 - rperryng
仍然是同样的蓝色，现在我要放图片了。 - Atlas91
请查看我的编辑。您应该膨胀使用可绘制对象的视图。 - rperryng

请查看此示例自定义导航抽屉

在onclick内部

  SelectItem.get(position).setColor(getResources().getColor("your color"));
0

这是我的做法，目前运行良好。简要概念是维护所选项在适配器中的位置，并在调用notifyDatasetChanged时调用notifyDataSetChanged，这将再次调用getView方法，并在获取视图时检查所选位置上的位置更改背景视图。详情请参见this答案。

如果您有任何疑惑，请随时提问。
