安卓中用代码设置顶部状态栏颜色

如何在Activity代码中设置当前页面的顶部状态栏和底部导航栏颜色？

 

调用下面这个方法即可，看示例代码

public static void setWindowStatusBarColor(Activity activity, int colorResId) {
        try {
            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
                Window window = activity.getWindow();
                window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);

                //顶部状态栏
                window.setStatusBarColor(activity.getResources().getColor(colorResId));

                //底部导航栏
                //window.setNavigationBarColor(activity.getResources().getColor(colorResId));
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

首先先在values下的color.xml加一个颜色值

<color name="Home_top">#780bbc</color>

颜色为:

调用上面的那个方法

public class Home extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setWindowStatusBarColor(Home.this,R.color.Home_top);
        setContentView(R.layout.activity_home);
   }

    public static void setWindowStatusBarColor(Activity activity, int colorResId) {
        try {
            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
                Window window = activity.getWindow();
                window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);

                //顶部状态栏
                window.setStatusBarColor(activity.getResources().getColor(colorResId));

                //底部导航栏
                //window.setNavigationBarColor(activity.getResources().getColor(colorResId));
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

效果如下
