Good day, late or night!! I need to make a screen in android split in the middle, where the screen on top screen a video player, and the bottom a chat, where in a due event will be replaced by another screen, a call screen that when accepting would once again be replaced by another, without changing the top screen (the video player).

Tela um  

  tela 2

Screen 1 will always be, and screen 2 can be replaced by another screen, I tried for Ragment but unfortunately it gave error, so if someone can give me a light I am grateful, Thank you

[EDIT1] xml code I tried and failed

<?xml version="1.0" encoding="utf-8"?>

<fragment xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/container1"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:name="fragmentAovivo.videoFragem"
    tools:layout="@layout/fragment_video_fragem"
    android:layout_weight="1"

    >
</fragment>


<ImageView
    android:layout_width="match_parent"
    android:layout_height="35dp"
    android:src="@mipmap/borda_chamada"
    />
<fragment xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/container2"

    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_weight="1"


    tools:layout="@layout/fragment_chat">



</fragment>

android android-studio android-layout android-activity

  • Post what you have so far

  • Posted the Activity xml code I tried !

  • Jean, why not just use one fragment? If screen 1 does not change place, make it a hierarchy of views and below that put the fragment container.

  • @Lennoardsilva could do that, but she has a chance of having to change her too, so it would have to be both, thank you for the answer.
