更改导航抽屉中所选项目的背景颜色

我想更改导航抽屉中所选项目的蓝色。我可以在点击某个项目但不在活动项目中时更改它。这就是我使用的：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>

color.xml 

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

然后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"/>

因此，选择的当前项目不会改变颜色。任何想法？

使用java nav抽屉编辑：

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;

@Override
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);
    }
}

/**
* Controllo la versione di android, se Kitkat o superiore rendo la nav bar trasparente
* */
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
        Window w = getWindow(); // in Activity's onCreate() for instance

        w.setFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION, WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION);
        w.setFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS, WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);

SystemBarTintManager systemBarTintManager = new SystemBarTintManager(this);
systemBarTintManager.setStatusBarTintEnabled(true);
systemBarTintManager.setStatusBarTintColor(Color.parseColor("#ff3600"));

/*systemBarTintManager.setNavigationBarTintEnabled(true);

    }

dataList.add(new DrawerItem("Altro")); // adding a header to the list
dataList.add(new DrawerItem("About", R.drawable.about));
//dataList.add(new DrawerItem("Settings", R.drawable.ic_action_settings));
dataList.add(new DrawerItem("Help", R.drawable.help));

这是激活项目中的标准颜色，我不想要！

看起来很好......

在托管listview的java代码中，调用myListView.setItemChecked(position, true);

此外，您为state_activated设置的颜色与抽屉处于normal状态时的颜色相同。这是打算吗？...

使用TextView创建一个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]" />
{/ 1}}中的

适用于您的适配器

getview()

检查此示例自定义导航抽屉

在onclick里面

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

答案 2 :(得分：0)

这是我的工作方式，它正在运作，简短的概念维持适配器中所选项目的位置并调用{ {1}}在调用notifyDataSetChanged时再次调用notifyDatasetChanged方法，并在获取视图中检查所选位置上的位置是否更改背景视图。有关详细信息，请参阅this answer。
