Change Navigation View Item Color Dynamically Andr

问题:

I'd like to build a navigation drawer where each item has a different selection color (the icon tint and text color) as the google play store has:

I'm not sure how they've solved this, I think they use different activities with different drawers. I want to use fragments and I want to change the icon tint and text color. Any ideas how I can do this? I'm using google's design support library and a drawer layout with a navigation view in there.

回答1:

use app:itemIconTint in your NavigationView for icons and use app:itemTextColor for textColors

Sample :

drawable/navigation_text_color :

<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <!-- This is used when the Navigation Item is checked -->
    <item android:color="#009688" android:state_checked="true" />
    <!-- This is the default text color -->
    <item android:color="#E91E63" />
</selector>

and layout :

<android.support.design.widget.NavigationView
       .
       .
       app:itemTextColor="@drawable/navigation_text_color"/>

If by dynamically you mean programmatically you could try this:

// FOR NAVIGATION VIEW ITEM TEXT COLOR
int[][] states = new int[][]{
        new int[]{-android.R.attr.state_checked},  // unchecked
        new int[]{android.R.attr.state_checked},   // checked
        new int[]{}                                // default
};

// Fill in color corresponding to state defined in state
int[] colors = new int[]{
        Color.parseColor("#747474"),
        Color.parseColor("#007f42"),
        Color.parseColor("#747474"),
};

ColorStateList navigationViewColorStateList = new ColorStateList(states, colors);

// apply to text color
navigationView.setItemTextColor(navigationViewColorStateList);

// apply to icon color
navigationView.setItemIconTintList(navigationViewColorStateList);

So you could define multiple colors for different settings like Day or Night.

Finllay i got the answer,

You must change the colorAccent in the colors file to which ever color you want :

  <color name="colorAccent">whichever color required</color>

This solution worked for me

    <android.support.design.widget.NavigationView
           .
           .
           app:itemIconTint="@color/your_selector_file_name" // for Icon
        app:itemTextColor="@color/your_selector_file_name" // for text
/>

Adding to what @DAVOOD said. The below color selector worked for me.

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
        <!-- This is used when the Navigation Item is checked -->
        <item android:color="@color/tenoBrandColor" android:state_pressed="true" />
        <!-- This is the default text color -->
        <item android:color="@color/textprimary" />
</selector>

There's a simpler option for the lazy ones out there.

TL;DR: Just create a new style with the colorPrimary being your desired color and then set the NavigationView's theme to be this new style.

Just make a new style as:

<style name="AppTheme.NoActionBar.NavigationView">
    <item name="colorPrimary">@color/myDesiredColor</item>
</style>

This style will automatically inherit from your base theme (on my case it was AppTheme.NoActionBar) and then you just have to set the colorPrimary with your desired color.

Then you just have to set the NavigationView's theme as:

android:theme="@style/AppTheme.NoActionBar.NavigationView"

in:

<android.support.design.widget.NavigationView
    android:id="@+id/nav_view"
    android:layout_width="wrap_content"
    android:layout_height="match_parent"
    android:layout_gravity="start"
    android:fitsSystemWindows="true"
    app:headerLayout="@layout/nav_header_menu_test"
    app:menu="@menu/main_drawer"
    android:theme="@style/AppTheme.NoActionBar.NavigationView" />
