Java 更改导航抽屉中所选项目的背景颜色

Change background color of selected item in navigation drawer

提问by End.Game

I want change the blue color of selected item in the navigation drawer.. I can change it when you tap over an item but not in the active item. This is what I use: in the drawable folder

我想更改导航抽屉中所选项目的蓝色。我可以在您点击某个项目而不是活动项目时更改它。这是我使用的：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>

The color.xml

颜色.xml

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

And then in the layout of nav drawer:

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"/>

So, the current item selected not change color..any ideas?

所以，当前选择的项目不会改变颜色..有什么想法吗？

EDIT with java nav drawer:

使用 java 导航抽屉编辑：

        //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);
    }
}

This is the standard color in activated item that I DON'T WANT!

这是我不想要的激活项目的标准颜色！

I want this: #f2f8ee

我想要这个：#f2f8ee

回答by rperryng

Looks fine...

看起来不错...

in your java code that hosts the listview, call myListView.setItemChecked(position, true);

在托管列表视图的 Java 代码中，调用 myListView.setItemChecked(position, true);

Also, the color you set for state_activatedis the same as when the drawer is in its normalstate. Is this intended?...

此外，您设置的颜色state_activated与抽屉处于其normal状态时的颜色相同。这是故意的吗？...

Create an xml file with a TextView

使用 TextView 创建一个 xml 文件

nav_drawer_item.xml

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]" />

in getview()for your adapter

在getview()您的适配器

@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;
}

check this sample custom navigation drawer

检查此示例自定义导航抽屉

inside onclick

里面点击

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

回答by Syed Raza Mehdi

here is how i have done and it is working, the brief conceptis maintain the positionof selected item in adapterand call notifyDataSetChangedon calling notifyDatasetChangedthe getViewmethod is called again and in get view check the position on the selected position change the background view. For details see thisanswer.

这是我所做的并且它正在工作，简单的概念是在适配器中保持所选项目的位置，并再次调用调用该方法的方法，并在获取视图中检查所选位置上的位置更改背景视图。有关详细信息，请参阅此答案。notifyDataSetChangednotifyDatasetChangedgetView
