java – how to align parent bottom in android linear layout?

Posted by: admin May 14, 2020 Leave a comment

Questions:

I have a linearlayout

and I want to create at the bottom of it a slice.

I know there are some options, but I’m a bit confused

1) android:layout_gravity:"bottom" –> this doesn’t work for me for some reason.

2) android:gravity_weight="0" and give the sibling before it android:gravity_weight:"1"

3) android:height="wrap_content" and give the sibling before it android:height:"match_parent"

I know how to do this using relativeLayout, but I want to practice linearLayout

what would you suggest?

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@color/blue_bg"
    android:orientation="vertical" >

   <ImageView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginBottom="10dp"
        android:layout_marginTop="5dp"
        android:src="@drawable/signup_illu_why" />
    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_weight=""
        android:orientation="horizontal" />

    <ImageView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:src="@drawable/signup_skip_icon" />

</LinearLayout>
How to&Answers:

Actually, you can set the parent element’s gravity to bottom

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@color/blue_bg"
    android:orientation="vertical"
    android:gravity="bottom" >

   <ImageView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginBottom="10dp"
        android:layout_marginTop="5dp"
        android:src="@drawable/signup_illu_why" />
    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_weight=""
        android:orientation="horizontal" />

    <ImageView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:src="@drawable/signup_skip_icon" />

</LinearLayout>

</LinearLayout>

Answer:

surround your linear layout with framelayout and give gravity as bottom..
its simple than you think… many layouts are used just for easier move towards design

<FrameLayout
android:layout_height="fill_parent"
android:layout_width = "fill_parent">

<LinearLayout`
android:layout_height="wrap_content"
android:layout_width = "wrap_content"
android:layout_gravity = "bottom"
android:orientation = "vertical">

<Button
android:layout_height="wrap_content"
android:layout_width = "wrap_content"
android:text = "btn"/>

</LinearLayout>

</FrameLayout>

Answer:

Use:

android:gravity="bottom"

example:

<LinearLayout
  android:layout_weight="7"
  android:layout_width="0dp"
  android:layout_height="match_parent"
  android:orientation="vertical"
  android:weightSum="5">
  <TextView
     android:layout_width="match_parent"
     android:layout_height="wrap_content"
     android:text="some text"
     android:layout_weight="2"
     android:gravity="bottom" />
  <TextView
     android:layout_width="match_parent"
     android:layout_height="wrap_content"
     android:text="some text"
     android:layout_weight="1" />
  <TextView
     android:layout_width="match_parent"
     android:layout_height="wrap_content"
     android:text="some text"android:gravity="center"
     android:layout_weight="2" />
</LinearLayout>
