There are two ways to change the color of the Android top bar: by modifying the theme or dynamically changing it in the code.

  1. Define a new theme in the res/values/styles.xml file as shown below:
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
    <item name="colorPrimary">@color/colorPrimary</item> // 修改顶部栏的颜色
</style>

Then define the color values in the res/values/colors.xml file as shown below:

<color name="colorPrimary">#ff0000</color> // 设置顶部栏颜色为红色

Finally, apply the theme to the corresponding Activity in the AndroidManifest.xml file, as shown below:

<activity android:name=".MainActivity"
    android:theme="@style/AppTheme">
</activity>
  1. You can dynamically modify the color of the top bar in an Activity by using the following code.
getSupportActionBar().setBackgroundDrawable(new ColorDrawable(getResources().getColor(R.color.colorPrimary)));

colorPrimary is a color value defined in colors.xml.

The color of the Android top bar can be changed by using either of the above methods.
