Android: layout_below and layout_alignParentBottom

Question

So I have the following layout

ScrollView

RelativeLayout
    TextView1
    EditText1

    TextView2
    EditText2

    TextView3
    EditText3

    TextView4
    EditText4

    TextView5
    EditText5: 
         android:id="@+id/txtPassword"

    LinearLayout: 
         android:id="@+id/Linearlayout1"
         layout_alignParentBottom="true" 

         Button1
         Button2

Here's the problem When I click the txtPassword EditText to enter some text Button1&Button2 from the LinearLayout overlaps or becomes on top of txtPassword

Someone suggested that I use android:layout_below="@id/txtPassword" for the Linear Layout but that makes the layout_alignParentBottom="true" useless because it will put the LinearLayout right below txtPassword and not at the bottom.

Answer 1

You might want to see if this can be fixed using different windowSoftInputMode settings. You could try to set android:windowSoftInputMode="adjustPan" for this specific activity. It will than move up the UI if the keyboard is visible and focused on a edittext. adjustResize can have the effect that some views overlap when the keyboard is visible.

Answer 2

use android:layout_below="@id/txtPassword" for the LinearLayout will work and doesn't make alignparentbottom="true" useless.

try it

<LinearLayout
        android:id="@+id/LinearLayout1"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        layout_below="@id/txtPassword"
        android:layout_alignParentBottom="true" >

When you use a Relative Layout and the Keyboard will be opened you LinearLayout will be above the keyboard

I'll suggest another solution and I think it will work:

Use a LinearLayout as parent and the last LinearLayout height fill parent and set the gravity bottom try this:

<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/signatureScroller"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fillViewport="true" >

<LinearLayout
    android:id="@+id/signatureLayout"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="#FFF"
    android:orientation="vertical"
    android:paddingBottom="20dp"
    android:paddingLeft="10dp"
    android:paddingRight="10dp" >

    <TextView
        android:id="@+id/textView1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginTop="20dp"
        android:text="@string/Meaning"
        android:textColor="#000"
        android:textSize="14sp" />

    <EditText
        android:id="@+id/txtMeaning"
