android:ems attribute in EditText

The em is simply the font size.

In an element with a 2in font, 1em thus means 2in. Expressing sizes, such as margins and paddings, in em means they are related to the font size, and if the user has a big font (e.g., on a big screen) or a small font (e.g., on a handheld device), the sizes will be in proportion.

Declarations such as 'text-indent: 1.5em' and 'margin: 1em' are extremely common in CSS.

putExtra() in android

If you want add information to your intent you can use this method.
This information is represented as tuple (key, value).

There are the number of value types that can be included into the extras of intent (for instance, int, int[], Bundle, Parcelable, and so on). For each this method there is a corresponding"read" method that is used to get the information from the intent.

So here is a possible example how to use this.

Imagine that you want explicitly call the activity B from activity A and pass to it an array of integers:

int intArray[]={1,2,3,4};
Intent in=new Intent(this, B.class);
in.putExtra("my_array", intArray);
startActivity(in);

To read the information in activity B (in onCreate() method) you should use the following code:

Bundle extras = getIntent().getExtras();
int[] arrayInB = extras.getIntArray("my_array");

Adding the image to the layout.

<?xml version=”1.0” encoding=”utf-8”?>
<LinearLayout xmlns:android=”http://schemas.android.com/apk/res/android”
android:orientation=”vertical”
android:layout_width=”fill_parent”
android:layout_height=”fill_parent” >

<ImageView
android:id=”@+id/icon”
android:layout_width=”wrap_content”
android:layout_height=”wrap_content”
android:layout_gravity=”center_horizontal”
android:src=”@drawable/mahi5” />

</LinearLayout>

An ImageView allows you to project an image to the device’s screen.

android:id=”@+id/icon”

The id attribute defines the unique identifier for the view in the Android system.

layout_gravity

This property defines how to place the view, both its x- and y-axis, with its parent. Here, I have defined the value as the center_horizontal constant. This value informs the Android system to place the object in the horizontal center of its container, not changing its size. You can use many other constants, such as center_vertical, top, bottom, left, right, and many more.

android:src=”@drawable/mahi5”

This property is a direct child of the ImageView class. You use this property to set the image that you would like to show up on the screen.

Viewing XML layout attributes.

xmlns:android=” ”

This defines the XML namespace that you will use to reference part of the Android SDK.

orientation=”vertical”

This informs Android that this view is to be laid out in a vertical fashion (like portrait format in printing).

android:layout_width=”fill_parent”

This informs the view that it should fill as much horizontal space as it can, up to its parent. In short, it should make the width as wide as it can be within the parent.

android:layout_height=”fill_parent”

This informs the view that it should fill as much vertical space as it can, up to its parent. In short, it should make the height as tall as it can be within the parent.

Android SDK Layouts

LinearLayout :-

A layout that arranges its children in a single row.

RelativeLayout :-

A layout where the positions of the children can be described in relation to each other or to the parent.

FrameLayout :-

This layout is designed to block out an area on the screen to display a single item. You can add multiple children to a FrameLayout, but all children are pegged to the upper left of the screen. Children are drawn in a stack, with the most recently added child at the top of the stack.This layout is commonly used as a way to lay out views in an absolute position.

TableLayout :-

A layout that arranges its children into rows and columns.
