Question

我的代码工作正常，但工具栏顶部有一个额外的填充。当我向上滑动图像时看起来很难看。我想删除这个填充。请参阅附图。感谢帮助。

Answer 1

我建议你试试活动

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    requestWindowFeature(Window.FEATURE_NO_TITLE);
    this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN);
}

删除android:fitsSystemWindows="true"或申请android:fitsSystemWindows="false"
