键盘弹出时如何隐藏元素？

Question

I have seen a few similar questions, but they want the things to show up, I want to hide them. Basically I have a bunch of elements in my RelativeLayout and when the activity shows, the keyboard pops up, since I have an editText, and the elements that are aligned in the Bottom go up along the keyboard, I don't want that, I want them to stay hidden, any idea how can I achieve this? This is the xml of my Activity:

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

            app:backgroundTint="@color/white" />

        <ImageButton
            android:id="@+id/btnbuscar"

        <ScrollView

            android:layout_marginStart="0dp"
            android:layout_marginTop="150dp"
            android:layout_marginBottom="50dp"
            android:fillViewport="true">

            <TableLayout
                android:id="@+id/tableInvoices"
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:padding="0dp"
                android:stretchColumns="*"></TableLayout>

        </ScrollView>

    </RelativeLayout>

</LinearLayout>

The last two elements before the scrollview are the ones that need to stay hidden.

Answer 1

add the following to your activity in the manifest:

android:windowSoftInputMode="adjustPan"

from the API :

The activity's main window is not resized to make room for the soft keyboard. Rather, the contents of the window are automatically panned so that the current focus is never obscured by the keyboard and users can always see what they are typing. This is generally less desirable than resizing, because the user may need to close the soft keyboard to get at and interact with obscured parts of the window.

Answer 2

By my understanding of your question you do not want the keyboard to push the UI elements at the bottom of your layout.

To achieve this all you need to do is put the following line into your manifest activity tag:

android:windowSoftInputMode="adjustNothing"
