A RelativeLayout is a ViewGroup that allows you to layout child elements in positions relative to the parent or siblings elements.

  1. Start a new project / Activity called HelloRelativeLayout.
  2. Open the layout file. Make it like so: 
    1

      <? xml version = "1.0" encoding = "utf-8"?> <RelativeLayout xmlns: android = "http://schemas.android.com/apk/res/android" android: layout_width = "fill_parent" android: layout_height = "fill_parent"> <TextView android:id="@+id/label" android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="Type here:"/> <EditText android: id = " @ + id / entry "android: layout_width =" fill_parent "android: layout_height =" wrap_content "android: background =" @ android: drawable / editbox_background "android: layout_below =" @ id / label "/> <Button android: id = "@ + id / ok" android: layout_width = "wrap_content" android: layout_height = "wrap_content" android: layout_below = "@ id / entry" android: layout_alignParentRight = "true" android: layout_marginLeft = "10dip" android: text = " OK "/> <Button android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_toLeftOf="@id/ok" android:layout_alignTop="@id/ok" android:text="Cancel" /> < / RelativeLayout>

    Pay attention to each of the additional layout_* attributes (besides the usual width and height, which are required for all elements). When using relative layout, we use attributes like layout_below and layout_toLeftOf to describe How we'd like to position each View. Naturally, these are different relative positions, and the value of the attribute is the id of the element we want the position relative to.

  3. Make sure your Activity loads this layout in the onCreate() method: 

    1

      public void onCreate (Bundle savedInstanceState) (super.onCreate (savedInstanceState); setContentView (R.layout.main);)

    R.layout.main refers to the main.xml layout file.

  4. Run it.

A TableLayout is a ViewGroup that will Lay child View elements into rows and columns.

  1. Start a new project / Activity called HelloTableLayout.
  2. Open the layout file. Make it like so: 
    1

      <? xml version = "1.0" encoding = "utf-8"?> <TableLayout xmlns: android = "http://schemas.android.com/apk/res/android" android: layout_width = "fill_parent" android: layout_height = "fill_parent" android: stretchColumns = "1"> <TableRow> <TextView android:layout_column="1" android:text="Open..." android:padding="3dip" /> <TextView android: text = " Ctrl-O "android: gravity =" right "android: padding =" 3dip "/> </ TableRow> <TableRow> <TextView android: layout_column =" 1 "android: text =" Save ... "android: padding = "3dip" /> <TextView android:text="Ctrl-S" android:gravity="right" android:padding="3dip" /> </ TableRow> <TableRow> <TextView android: layout_column = "1" android: text = "Save As ..." android: padding = "3dip" /> <TextView android:text="Ctrl-Shift-S" android:gravity="right" android:padding="3dip" /> </ TableRow > <View android:layout_height="2dip" android:background="#FF909090" /> <TableRow> <TextView android:text="X" android:padding="3dip" /> <TextView android: text = "Import. .. "android: padding =" 3dip "/> </ TableRow> <TableRow> <TextView android:text="X" android:padding="3dip" /> <TextView android: text =" Export ... "android : padding = "3dip" /> <TextView android:text="Ctrl-E" android:gravity="right" android:padding="3dip" /> </ TableRow> <View android: layout_height = "2dip" android: background = "# FF909090" /> <TableRow> <TextView android:layout_column="1" android:text="Quit" android:padding="3dip" /> </ TableRow> </ TableLayout>

    Notice How this resembles the structure of an HTML Table. TableLayout is like the table element; TableRow is like a tr element; but for our cells like the HTML td element, we can use any kind of View. Here, we use TextView for the cells.

  3. Make sure your Activity loads this layout in the onCreate() method: 
    1

      public void onCreate (Bundle savedInstanceState) (super.onCreate (savedInstanceState); setContentView (R.layout.main);)

    R.layout.main refers to the main.xml layout file.

  4. Run it.

You should see the following:

  1. Start a new project / Activity called HelloLinearLayout.
  2. Open the layout file. Make it like so: 
    1

      <? 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"> <LinearLayoutandroid:orientation="horizontal"android:layout_width="fill_parent"android:layout_height="fill_parent"android:layout_weight="1"> <TextView android: text = "red "android: gravity =" center_horizontal "android: background =" # aa0000 "android: layout_width =" wrap_content "android: layout_height =" fill_parent "android: layout_weight =" 1 "/> <TextView android: text =" green "android: gravity = "center_horizontal" android: background = "# 00aa00" android: layout_width = "wrap_content" android: layout_height = "fill_parent" android: layout_weight = "1" /> <TextView android: text = "blue" android: gravity = " center_horizontal "android: background =" # 0000aa "android: layout_width =" wrap_content "android: layout_height =" fill_parent "android: layout_weight =" 1 "/> <TextView android: text =" yellow "android: gravity =" center_horizontal "android : background = "# aaaa00" android: layout_width = "wrap_content" android: layout_height = "fill_parent" android: layout_weight = "1" /> </ LinearLayout> <LinearLayoutandroid: orientation = "vertical" android: layout_width = "fill_parent" android : layout_height = "fill_parent" android: layout_weight = "1"> <TextView android: text = "row one" android: textSize = "15pt" android: layout_width = "fill_parent" android: layout_height = "wrap_content" android: layout_weight = " 1 "/> <TextView android:text="row two" android:textSize="15pt" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_weight="1"/> <TextView android: text = "row three" android: textSize = "15pt" android: layout_width = "fill_parent" android: layout_height = "wrap_content" android: layout_weight = "1" /> <TextView android: text = "row four" android: textSize = "15pt "android: layout_width =" fill_parent "android: layout_height =" wrap_content "android: layout_weight =" 1 "/> </ LinearLayout> </ LinearLayout>

    Carefully inspect the XML. You'll notice how this layout works a lot like an HTML layout. There is one parent LinearLayout that is defined to lay its child elements vertically. The first child is another LinearLayout that uses a horizontal layout and the second uses a Vertical layout. Each LinearLayout contains several TextView elements.

  3. Now Open the HelloLinearLayout Activity and be sure it loads this layout in the onCreate() method: 

    1

      public void onCreate (Bundle savedInstanceState) (super.onCreate (savedInstanceState); setContentView (R.layout.main);)

    R.layout.main refers to the main.xml layout file.

  4. Run it.

You should see the following:

Link Address: http://androidappdocs.appspot.com/guide/tutorials/views/hello-linearlayout.html

Note: LinearLayout is the line of the layout, orientation = "horizontal": horizontally; orientation = "vertical": vertical alignment

To understand: the concept of the layout is similar to the framework, if the custom layout style, then any component inside, all will be arranged in the style. For example: horizontally, then the

Component will be placed side by side a line at a certain level. (Personal understanding)
