Put text and image on the same line

I'm trying to put text and an image on the same line but for one reason or another it's not working. The text is coming up fine but there is no sign of the image.
<LinearLayout
android:id="#+id/list_item3"
android:layout_width="match_parent"
android:layout_height="42dp"
android:layout_below="#+id/list_item"
android:layout_centerHorizontal="true"
android:layout_centerInParent="true"
android:background="#DCDBDB" >
<TextView
android:id="#+id/TextView03"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="0.00"
android:text="#string/quoteDevil"
android:textSize="21sp" />
<ImageView
android:layout_width="33dp"
android:layout_height="match_parent"
android:layout_marginRight="15dp"
android:src="#drawable/nextarrow" />
</LinearLayout>

FYI: There is a "tip" for displaying an image within a TextView.
In fact, any images stored in the drawable folders can actually be embedded within a TextView at several key locations in relation to the text using the android:drawableRight / android:drawableLeft and the android:drawablePadding property.
An example:
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="center"
android:text="#string/my_contacts"
android:drawableRight="#drawable/ic_action_add_group"
android:drawablePadding="8dp"
/>
The result is:

The best way to have two things in one row is to use TableRow
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/list_item3"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="#+id/list_item"
android:layout_centerHorizontal="true"
android:layout_centerInParent="true">
<TableRow
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<TextView
android:id="#+id/TextView03"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="#string/quoteDevil"
android:textSize="21sp" />
<ImageView
android:layout_width="33dp"
android:layout_height="match_parent"
android:layout_weight="1"
android:layout_marginRight="15dp"
android:src="#drawable/nextarrow" />
</TableRow>
</LinearLayout>
but if you want to use LinearLayout you have to define orientation as horizontal
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/list_item3"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="#+id/list_item"
android:orientation="horizontal"
android:layout_centerHorizontal="true"
android:layout_centerInParent="true">
<TextView
android:id="#+id/TextView03"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/quoteDevil"
android:textSize="21sp" />
<ImageView
android:layout_width="33dp"
android:layout_height="match_parent"
android:layout_marginRight="15dp"
android:src="#drawable/nextarrow" />
</LinearLayout>

U need to add orientation property to LinearLayout:
android:orientation="horizontal"
and change the width property from the inside elements from match_parent to wrap_content, if you put match_parent only show one element
Change
android:layout_width="match_parent"
For
android:layout_width="wrap_content"
Example
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/list_item3"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
<TextView
android:id="#+id/TextView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</LinearLayout>

In RelativeLayout
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<ImageView
android:id="#+id/imageView2"
android:layout_width="80dp"
android:layout_height="80dp"
app:srcCompat="#drawable/centra_crm" />
<TextView
android:id="#+id/textView2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_toEndOf="#+id/imageView2"
android:padding="5dp"
android:singleLine="true"
android:text="Title" />
</RelativeLayout>

Can't align view to the right

I am trying to display one view in the left side and one to the right side of the parent layout as following:
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="left"
android:layout_gravity="left" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="right"
android:layout_gravity="right" />
</LinearLayout>
But as a result I see both textViews aligned to the left only. I don't understand why. I manage to set the verticaly layout_gravity but not the horizontal one. In addition, I could add:
android:gravity="right"
to the parent layout and than see both views on the right side but couldnt find a way to display one in the left side and one in the right side.
Please help.

Another trick here;
Place an invisible View between the TextViews. And it will occupy the whole remaining area with android:layout_weight="1", so TextViews will remain on both ends. No gravity needed. Try the code below :)
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal" >
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="left" />
<View
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="right" />
</LinearLayout>

You can try this as well
<LinearLayout
android:layout_width="match_parent"
android:orientation="horizontal"
android:layout_height="match_parent">
<TextView
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:gravity="left"
android:text="left" />
<TextView
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:gravity="right"
android:text="right" />
</LinearLayout>

Try this:
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal" >
<TextView
android:layout_width="0dip"
android:layout_height="wrap_content"
android:layout_weight="1"
android:gravity="left"
android:text="left" />
<TextView
android:layout_width="0dip"
android:layout_height="wrap_content"
android:layout_weight="1"
android:gravity="right"
android:text="right" />
</LinearLayout>
Or Try the following
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="#dimen/activity_vertical_margin"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
tools:context=".MainActivity" >
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:text="left" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:text="right" />
</RelativeLayout>
Edit:
In method 1 using weight for splitting the total screen as two parts and set the gravity for first item is left and gravity for second item is right.
I am not using android:layout_gravity for TextView . Using android:gravity. Better practise you can use relativeLayout. Check the second option

Set android:layout_weight="1" to both your TextViews

Use Relativelayout instead
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:text="left" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:text="right" />
</RelativeLayout>

<?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:weightSum="100"
android:orientation="horizontal">
<TextView
android:layout_weight="50"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:text="left"
android:gravity="left" />
<TextView
android:layout_weight="50"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:text="right"
android:gravity="right" />
</LinearLayout>

try this:
<?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:baselineAligned="false"
android:orientation="horizontal" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="1"
android:gravity="left" >
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="left" />
</LinearLayout>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="1"
android:gravity="right" >
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="right" />
</LinearLayout>
</LinearLayout>

The easiest solution with LinearLayout is modifying your right textview with gravity="right"
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="right"
android:gravity="right" />
But I would strongly reccomend using a RelativeLayout as #Sjd suggested.

Alignment of two Relative layout within a main relative layout

The above code is written by me to achieve the following figure:.But what I am achieving is this: or this:.
I have absolutely no clue about what is the mistake I am doing here??I am just using a main relative layout
OtherWeatherInfo_main and within that I am embedding two relative layouts to represent the two weather attributes. #dimen/weather_space is 145 dp.I am unable to align the two relative layout within the main layout equally.Any help will be appreciated.

Wrap the two RelativeLayouts inside a LinearLayout with horizontal orientation and then assign both the RelativeLayouts equal weight.
In general, something like this:
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:weightSum="1" >
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:weight="0.5" />
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:weight="0.5" />
</LinearLayout>

Remove either this
android:layout_alignParentRight="true"
or this
android:layout_toRightOf="#+id/OtherWeatherInfo"
from your second layout.
Also you can wrap both your RelativeLayouts to the horizontal LinearLayout and use android:layout_weight attribute

Try this way,if you wan achieved your design using LinearLayout.
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:gravity="center">
<TextView
android:id="#+id/txtCityName"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Kolkata"/>
<ImageView
android:id="#+id/imgWeather"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/ic_launcher"
android:layout_marginTop="20dp"/>
<TextView
android:id="#+id/txtTemprature"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="28 C"
android:layout_margin="10dp"/>

Unable to use android:weightSum properly

I'm trying to build a layout. The code is below.
I'm unable to add proper weight to layouts. The code below doesn't create a layout with weights. The layout is same with and without the weights added!
Forgive me if I've not explained it properly. I'm completely new to programming.
<?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:orientation="vertical"
android:weightSum="100" >
<ScrollView
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_weight="30" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<TextView

android:layout_width="match_parent"
android:layout_height="wrap_content"
android:ems="10" />
</LinearLayout>
</ScrollView>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="fill_parent"
android:layout_weight="40"
android:orientation="vertical" >
<Button
android:id="#+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Button" />
</LinearLayout>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="fill_parent"
android:layout_weight="30"
android:orientation="vertical" >
<AnalogClock
android:id="#+id/analogClock1"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</LinearLayout>

layout_weight mechanism distributes any remaining space in the layout in proportion to child weights. Your views already take up all space with fill_parent so there's no remaining space for the weight mechanism to distribute. Set the weighed layout children heights to 0px so that there is actually some space to distribute by weight.
Also, specifying the weight sum is often redundant. The layout itself can calculate the sum of child weights for you.

Scroll View does not have Weight sum property if you want to set layout according to weight then remove Scroll View otherwise just use Scroll view you don't need weight sum in scroll view.

Set TextView width according to other View's width

I have a ImageView, the image is loaded from the net and can vary in width.
Below I have a TextView with a description of the image. I want the TextView to be exactly as wide as the ImageView.
My try was this:
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:orientation="vertical" >
<ImageView
android:id="#+id/iv"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal" />
<TextView
android:id="#+id/imagedescription"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:textAppearance="#style/SmallTextGray" />
</LinearLayout>
which somehow works as the TextView's width is set accoring to that of the ImageView, but the TextView end after 2 lines:
I know I could set the TextView's width programmatically after I know the image's width, but is there also a way to do it in the XML layout?

I don't know if it will work, but try doing in your code, after load the image:
textView.setWidth(imageView.getDrawable().getIntrinsicWidth());

With a small change of layout: replace LinearLayout with a RelativeLayout:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content" >
<ImageView
android:id="#+id/iv"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true" />
<TextView
android:id="#+id/imagedescription"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignLeft="#+id/iv"
android:layout_alignRight="#+id/iv"
android:layout_below="#+id/iv"
android:layout_marginTop="8dp"
android:gravity="center_horizontal"
android:textAppearance="#style/SmallTextGray" />
</RelativeLayout>
This way the TextView is always below imageView and its bounds are aligned to imageViews

You can use weight like this:
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:weightSum="5">
<Button
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="1" />
<Button
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="3"
android:text="2" />
<Button
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="3" />

You can use the wight property in xml and give equal weight to both imageview and textview. then both size will be equal

In your case do this:
<ImageView
android:id="#+id/iv"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:layout_gravity="center_horizontal" />
<TextView
android:id="#+id/imagedescription"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:layout_weight="1"
android:textAppearance="#style/SmallTextGray" />
</LinearLayout>

Try This.This will work
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_gravity="center_horizontal"
android:orientation="vertical" >
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:layout_gravity="center_horizontal"
android:orientation="vertical" >
<ImageView
android:id="#+id/iv"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
/>
<TextView
android:id="#+id/imagedescription"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="center_horizontal"
android:typeface="monospace" />
</LinearLayout>
</LinearLayout>

This works for me:
<?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"
