在没有闪光灯的情况下切换活动

Question

I've searched long and hard for an answer to this question but can't find any answers. My problem is that I created an XML file with 5 buttons on it and each button is linked to another xml file. Once clicked, the button takes you to the next xml file with the same 5 buttons in the same location. The problem I face is that when the pages are switching, there is an ever so slight flash of black. Then there's a second where the toolbar loads. How do I fix this annoying lag and make it fluid?

Answer 1

Instead of switching between activities you can simply change between the layout xml files.

xml layout1

<Button
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="New Button"
    android:id="@+id/button"
    android:layout_centerVertical="true"
    android:layout_centerHorizontal="true"
    android:onClick="newLayout"/>

java code

 public void newLayout(View view) {
    setContentView(R.layout.new_layout);

}
