Android keyboard does not override buttons

Question

On one of the screens of my application:

When I open the keyboard it overwrites the finished button:

Screen that original Food Registry

Answer 1

In the Manifest add the following configuration of Activity:

android:windowSoftInputMode="adjustPan"

The android:windowSoftInputMode is responsible for the form of interaction of the main window of the activity with the window containing the software keyboard on the screen. Setting the value of this attribute to adjustPan, the main window of the activity is not resized to create space for the software keyboard on the screen. Instead, you move the contents of the window automatically so that the current focus is never overlaid by the keyboard and users can always see what they type. Typically, this behavior is less desirable than resizing, as the user may need to close the software keyboard to access and interact with the overlapping parts of the window.

One solution is you use the ScrollView. With it you can drag the screen so that you can see hidden elements below the keyboard. It is usually used when you have several views on the same screen. See an example:

<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fillViewport="true">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical">

        <!-- coloque todo seu código aqui dentro -->

    </LinearLayout>
</ScrollView>

For more details, see the documentation.

Another option would be for you to insert your button into your Toolbar, but if you have many views you will fall into the same situation.
