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:
public class MainActivity extends Activity {
private DrawerLayout mDrawerLayout;
private ListView mDrawerList;
private ActionBarDrawerToggle mDrawerToggle;
private CharSequence mDrawerTitle;
private CharSequence mTitle;
CustomDrawerAdapter adapter;
List<DrawerItem> dataList;

protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
/** Customizzo la actionbar */
ActionBar actionBar = getActionBar();
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!
我想要的是:#f2f8ee
mDrawerList.setItemChecked(possition, true); setTitle(dataList.get(possition).getItemName()); mDrawerLayout.closeDrawer(mDrawerList);
但还是不起作用 :-( - Atlas91<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
