Aligning Text and Icons in a TextView Android

i am working on a ui design assignment in android studio. i have been able to get this
here is my code
<?xml version="1.0" encoding="utf-8"?>

</RelativeLayout>
I want to align the icons and text in the text views on the same line and with the same size. my question is that how do i do this? please point out my errors and help me with fixing this.

If this is what you want, then you just need change gravity from
android:gravity="center" to android:gravity="center_vertical"

Please add gravity property to your TextView with center alignment and
icon size change with 24dp.
<TextView android:text="Event Planning and Decoration, Beads and Jewelry Making, Props and Bridals, Aso-Oke #WeMakePoshDesign"
android:drawableLeft="#drawable/about"
android:layout_below="#+id/topImage"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:drawablePadding="5dp"
android:padding="10dp"
android:textSize="16dp"
android:gravity="center"
android:fontFamily="sans-serif-black"
android:background="#F0E68C"
android:id="#+id/descText" />

It seems you want to use a compound drawable, see this answer:
How do I use a compound drawable instead of a LinearLayout that contains an ImageView and a TextView

Different XML in mobile

I have this XML code:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent" android:layout_height="match_parent">
<EditText
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:id="#+id/editText"
android:hint="enter your name"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true" />
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="button"
android:id="#+id/button"
android:layout_below="#+id/editText"
android:layout_centerHorizontal="true"
android:layout_marginTop="20dp"/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textAppearance="?android:attr/textAppearanceLarge"
android:text="name"
android:id="#+id/textView8"
android:layout_below="#+id/button"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"
android:layout_marginLeft="20dp"/>
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/button2"
android:text="copy"
android:layout_alignBottom="#+id/textView8"
android:layout_alignParentRight="true"
android:layout_alignParentEnd="true" />
</RelativeLayout>
In AVD, it looks like this:
And in mobile, it looks like this:
How can I make them look the same?

This discrepancy occurs because you're using the RelativeLayout quite carelessly. Relative Layout positions items relatively to one another, so it might look different across different devices.
I'd suggest that you use one vertical LinearLayout and to have it have 2 horizontal LinearLayouts as its children, as the rows in which you put these fields. I will provide some modified code of yours below, but keep in mind that this will look the same on each device, and you need to make it look prettier, as this is just an example. Something like this:
<LinearLayout 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:orientation="vertical">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="wawdsd"/>
</LinearLayout>
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:baselineAligned="true">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textAppearance="?android:attr/textAppearanceLarge"
android:text="name"
android:id="#+id/textView8" />
<EditText
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:id="#+id/editText"
android:hint="enter your name" />
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="button"
android:id="#+id/button"
android:layout_marginTop="20dp"/>
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/button2"
android:text="copy"/>
</LinearLayout>

How to vertically combine two editTexts in a linearlayout

This is my aim:
I have a linearlayout where everything is centered both vertically and horizontally
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center">
<EditText
android:id="#+id/username"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/top_edittext_form_bg"
android:hint="Email or Username"
android:layout_gravity="center_horizontal"
android:layout_margin="5pt"/>
<EditText
android:id="#+id/password"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/bottom_edittext_form_bg"
android:inputType="textPassword"
android:hint="Password"
android:layout_gravity="center_horizontal"
android:layout_margin="5pt" />
...
I have been messing around trying to take out the layout_margin, but this affects all elements (even the ones underneath these two).
Is there any way for me to simply combine these two edittexts like in the picture without affecting my linearlayout?

Try this:
...
<EditText
android:id="#+id/username"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/top_edittext_form_bg"
android:hint="Email or Username"
android:layout_gravity="center_horizontal"
android:layout_marginTop="5pt"
android:layout_marginLeft="5pt"
android:layout_marginRight="5pt"
/>
<EditText
android:id="#+id/password"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/bottom_edittext_form_bg"
android:inputType="textPassword"
android:hint="Password"
android:layout_gravity="center_horizontal"
android:layout_marginBottom="5pt"
android:layout_marginLeft="5pt"
android:layout_marginRight="5pt"
/>
...
Tell me if it works. :)

Relativeview 5 buttons, don't understand my mistake

I'm trying to make myself an app to track my progress at the gym since it's one of my new year resolution... I don't go to the gym, and I figure that if I can track progress, i could have some interest in going back.
Here's my issue:
I'm doing my main layout right now, and I want one large button that says: Start workout.
I would like to have 4 buttons centered next to each other with some spaces between each other and the four together would have the form of a square.
I wrote this code, and nothing is working at all right now. I just don't even know where to look anymore. I know I could use LinearLayout but I read everywhere that RelativeLayout should be prioritize
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical">
<Button
android:id="#+id/start_workout"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:hint="#string/start_workout"
/>
<Button
android:id="#+id/log_button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:hint="#string/log_button"
/>
<Button
android:id="#+id/progress_button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:hint="#string/progress_button"
/>
<Button
android:id="#+id/cardio_button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_toRightOf="#+id/calendar_button"
android:layout_below="#id/progress_button"
android:hint="#string/cardio_button"
/>
<Button
android:id="#+id/calendar_button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_toLeftOf="#+id/cardio_button"
android:layout_below="#+id/log_button"
android:hint="#string/calendar_button" />
</RelativeLayout>

Here it is.
The first button is screen wide and top aligned.
The other four occupy each 1/4th the screen width and are all below the top one
<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"
>
<Button
android:id="#+id/start_workout"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
android:text="Start workout"
android:textSize="12sp"
/>
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_below="#id/start_workout"
android:orientation="horizontal"
>
<Button
android:id="#+id/cardio_button"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="Cardio"
android:textSize="12sp"
/>
<Button
android:id="#+id/progress_button"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="Progress"
android:textSize="12sp"
/>
<Button
android:id="#+id/calendar_button"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="Calendar"
android:textSize="12sp"
/>
<Button
android:id="#+id/log_button"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="Log"
android:textSize="12sp"
/>
</LinearLayout>
</RelativeLayout>

Try this,but better to use linear layout in your case
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/RelativeLayout1"
android:layout_width="match_parent"
android:layout_height="match_parent"
>
<Button
android:id="#+id/cardio_button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_below="#+id/log_button"
android:hint="cardio_button" />
<Button
android:id="#+id/progress_button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignBaseline="#+id/log_button"
android:layout_alignBottom="#+id/log_button"
android:layout_toRightOf="#+id/cardio_button"
android:hint="progress_button" />
<Button
android:id="#+id/calendar_button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignBaseline="#+id/cardio_button"
android:layout_alignBottom="#+id/cardio_button"
android:layout_toRightOf="#+id/cardio_button"
android:hint="calendar_button" />
<Button
android:id="#+id/log_button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#+id/start_workout"
android:layout_marginTop="50dp"
android:layout_toLeftOf="#+id/progress_button"
android:hint="log_button" />
<Button
android:id="#+id/start_workout"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
android:hint="start_workout" />
</RelativeLayout>

I can't get an image on the left side of my Android XML Layout to appear properly. What am I doing wrong here?

Here is what is looks like and here is my XML code.
Can someone please post the fixed XML layout code for me and explain what I am doing wrong? I want the - symbol on the left to be all of the way left, just like the > symbol on the right side. The black text should be just to the right of the - symbol.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<TableLayout
android:id="#+id/tableLayout1"
android:layout_width="fill_parent"
android:layout_height="44dip"
android:stretchColumns="0"
android:divider="#null"
>
<TableRow
android:id="#+id/tableRow1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/infocells"
android:divider="#null" >
<ImageView
android:id="#+id/imgDelete"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/minus" />
<TextView
android:id="#+id/txtKey"
android:text="Some text"
android:textSize="16dip"
android:textStyle="bold"
android:layout_marginLeft="8dip"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="left|center_vertical"
android:layout_weight="1.0"
android:layout_marginTop="11dp"
android:layout_marginBottom="6dp"

<TextView
android:id="#+id/txtValue"
android:text="Some text"
android:textSize="16dip"
android:layout_marginRight="8dip"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="right|center_vertical"
android:layout_weight="1.0"
android:layout_marginTop="11dp"
android:layout_marginBottom="6dp"
android:textColor="#color/darkblue"
/>
<ImageView
android:id="#+id/imageView1"
android:layout_marginTop="7dp"
android:layout_marginRight="7dp"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/arrow" />
</TableRow>
</TableLayout>
</LinearLayout>

Why don't you make use of RelativeLayout and using various property of it you can align your TextView and ImageView according to your other views.If u want to set a - to the left then make use android:layout_alignParentLeft="true" and android:layout_alignParentLeft="true" for you > to set it to the right of the layout

In your ImageView you can set your X position using translationX like something below:
<ImageView
android:id="#+id/imgDelete"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:translationX="-25"
android:src="#drawable/minus" />
Just try it. This is a quick solution only.

Here's an idea on how you can do it. Give it a try.
<RelativeLayout>
<ImageView
android:id="#+id/imgDelete"
android:layout_alignParentLeft="true" />
<TextView
android:id="#+id/txtKey"
android:layout_toRightOf="#+id/imgDelete" />
<TextView
android:id="#+id/txtValue"
android:layout_toRightOf="#+id/txtKey" />
<ImageView
android:id="#+id/imageView1"
android:layout_alignParentRight="true" />
</RelativeLayout>
