  2. <resources>
  3. <color name="window_background">#8AA5B9</color>
  4. </resources>

Step 6: Open Solution Explorer-> Project Name->Resources->values->styles.xml. Click to open Design View and the code, given below:

  2. <resources>
  3. <style name="Theme.DesignDemo" parent="Base.Theme.DesignDemo">

  8. </style>
  9. </resources>

Step 7: Open Solution Explorer-> Project Name->Resources->values->Strings.xml. Click to open Design View and the code, given below:

  1. <string name="pro_Languages1">Type of Languages</string>
  2. <string-array name="pro_Languages">
  3. <item>C#</item>

  7. <item>C++</item>
  8. <item>Swift</item>
  9. </string-array>
  10. </resources>

Step 8: Open Solution Explorer-> Project Name->Resources->layout ->Main.axml. Click to open Design View and the code, given below:

  1. <?xml version="1.0" encoding="utf-8"?>
  2. <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="match_parent" android:layout_height="match_parent">
  3. <LinearLayout android:orientation="vertical" android:layout_marginTop="80dp" android:layout_width="match_parent" android:layout_height="wrap_content">
  4. <android.support.design.widget.TextInputLayout android:layout_width="fill_parent" android:layout_height="wrap_content" android:id="@+id/textuernameInputLayout">
  5. <EditText android:layout_width="match_parent" android:layout_height="wrap_content" android:id="@+id/txtusername" android:hint="User Name" android:singleLine="true" /> </android.support.design.widget.TextInputLayout>
  6. <android.support.design.widget.TextInputLayout android:layout_width="fill_parent" android:layout_height="wrap_content" android:id="@+id/textpasswordInputLayout">
  7. <EditText android:layout_width="match_parent" android:layout_height="wrap_content" android:id="@+id/txtpassword" android:inputType="textPassword" android:hint="Password" android:singleLine="true" /> </android.support.design.widget.TextInputLayout>
  8. <Spinner android:id="@+id/ddlmechservicetype" android:layout_width="fill_parent" android:layout_height="wrap_content" />
  9. <Button android:text="Click" android:layout_width="match_parent" android:layout_height="wrap_content" android:id="@+id/btnclick" /> </LinearLayout>
  10. </LinearLayout>

Step 9: After Design view creation open Solution Explorer-> Project Name->MainActivity.cs then following below steps.

Step 10: Add below Namespaces,

  1. using Android.Support.V7.App;
  2. using Android.Support.Design.Widget;

Step 11: Create Spinner and TextInputLayout variable, declare the Spinner and TextInputLayout within the OnCreate().before to change to the Activity to AppCompatActivity.

  1. //TextInputLayout
  2. TextInputLayout txtlayoutusername = FindViewById < TextInputLayout > (Resource.Id.textuernameInputLayout);
  3. TextInputLayout textpasswordInputLayout = FindViewById < TextInputLayout > (Resource.Id.textpasswordInputLayout);
  4. EditText txtusername = FindViewById < EditText > (Resource.Id.txtusername);
  5. EditText txtpassword = FindViewById < EditText > (Resource.Id.txtpassword);
  6. Button btnclick = FindViewById < Button > (Resource.Id.btnclick);
  7. //Spinner
  8. spinner = FindViewById < Spinner > (Resource.Id.ddlmechservicetype);
  9. var adapter = ArrayAdapter.CreateFromResource(this, Resource.Array.pro_Languages, Android.Resource.Layout.SimpleSpinnerItem); //Assign Array List Strings
  10. adapter.SetDropDownViewResource(Android.Resource.Layout.SimpleSpinnerDropDownItem);
  11. spinner.Adapter = adapter;
  12. //Button Click
  13. btnclick.Click += (sender, e) =>
  14. {
  15. //Showing Notifications
  16. Toast.MakeText(this, txtusername.Text, ToastLength.Short).Show();
  17. Toast.MakeText(this, txtpassword.Text, ToastLength.Short).Show();
  18. Toast.MakeText(this, spinner.SelectedItemPosition.ToString(), ToastLength.Short).Show();
  19. };

Step 12: Press F5 or build and run the Application.

Finally, we successfully created Xamarin Android TextInputLayout and Spinner app.
