使用：

public class BaseActivity extends AppCompatActivity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        initStatusBar();
    }

    @Override
    protected void onDestroy() {
        super.onDestroy();
        ButterKnife.unbind(this);
    }

    private void initStatusBar() {
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
            setTranslucentStatus(true);
        }

        SystemBarTintManager tintManager = new SystemBarTintManager(this);
        tintManager.setStatusBarTintEnabled(true);
        tintManager.setNavigationBarTintEnabled(true);
        tintManager.setStatusBarTintColor(getResources().getColor(R.color.colorPrimaryDark));
    }

    @TargetApi(19)
    private void setTranslucentStatus(boolean on) {
        Window win = getWindow();
        WindowManager.LayoutParams winParams = win.getAttributes();
        final int bits = WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS;
        if (on) {
            winParams.flags |= bits;
        } else {
            winParams.flags &= ~bits;
        }
        win.setAttributes(winParams);
    }
}
