Change the UI strings

Change the UI strings

Click Show Design  in the toolbar to preview the UI. Notice that the text input is pre-filled with "Name" and the button is labeled "Button." So now you'll change these strings.
  1. Open the Project window and then select res > values > strings.xml.
    This is a string resources file where you should specify all your UI strings. Doing so allows you to manage all UI strings in a single location, which makes it easier to find, update, and localize (compared to hard-coding strings in your layout or app code).
  2. Click Open editor at the top of the editor window. This opens the Translations Editor, which provides a simple interface for adding and editing your default strings, and helps keep all your translated strings organized.

  3. Figure 7. The dialog to add a new string
    Click Add Key  to create a new string as the "hint text" for the text box.
    1. Enter "edit_message" for the key name.
    2. Enter "Enter a message" for the value.
    3. Click OK.
  4. Add another key named "button_send" with a value of "Send."
Now you can set these strings for each view. So return to the layout file by clickingactivity_main.xml in the tab bar, and add the strings as follows:
  1. Click the text box in the layout and, if the Properties window isn't already visible on the right, click Properties  on the right sidebar.
  2. Locate the hint property and then click Pick a Resource  to the right of the text box. In the dialog that appears, double-click on edit_message from the list.
  3. Still viewing the text box properties, also delete the value for the text property (currently set to "Name").
  4. Now click the button in the layout, locate the text property, click Pick a Resource, and then select button_send.

Make the text box size flexible

Make the text box size flexible To create a layout that's responsive to different screen sizes, you'll now make the text box stretch to fill all remaining horizontal space (after accounting for the button and margins). Figure 8.  Click to change the width and remove the right margin Figure 9.  The text box stretches to fill the remaining space Create a constraint from the right side of the button to the right side of the parent layout. This now defines the total width that the two views have available (which you can now fill with the text box). Add a constraint from the right side of the text box to the left side of the button. It might look like that's already there, but you're actually adding a bidirectional constraint between the two views. So both views are constrained to each other. This is called a  chain  (as indicated by the chain betwen the views), and it enables some extra layout options. Open the  Properties  window for the text box and the

Add Text box & Button

Add a text box Figure 5.  The text box is constrained to the top and left of the parent layout First, you need to remove what's already in the layout. So click  TextView  in the  Component Tree  window, and then press Delete. From the  Palette  window on the left, click  Text  in the left pane, and then drag  Plain Text  into the design editor and drop it near the top of the layout. This is an  EditText  widget that accepts plain text input. Click the view in the design editor. You can now see the resizing handles on each corner (squares), and the constraint anchors on each side (circles). For better control, you might want to zoom in on the editor to 75% or higher using the buttons in the toolbar. Click-and-hold the anchor on the top side, and then drag it up until it snaps to the top of the layout and release. That's a constraint—it specifies the view should be 16dp from the top of the layout (because you set the default margins to 16dp). Similarly, create a c
