public class StatusBarUtils {
    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);

                window.setStatusBarColor(activity.getResources().getColor(colorResId));



                //底部導航欄
 


                //window.setNavigationBarColor(activity.getResources().getColor(colorResId));

            }

        } catch (Exception e) {

            e.printStackTrace();

        }

    }
}

在activity中進行設定：

public class MainActivity extends AppCompatActivity {
    @Override
    protected void
 
 onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        StatusBarUtils.setWindowStatusBarColor(MainActivity.this,R.color.colorPrimary);
        setContentView(R.layout.activity_main);
      }
    }
