Android Spinter Markup

I set the dynamic value in the counter. I am using the following code for it.

spinner_generalbooks.setAdapter(new ArrayAdapter<String>(getApplicationContext(), android.R.layout.simple_spinner_item, new String[]{"Author","ISBN","Keyword","Title"}));

It works fine, but I have a problem with the view of the counter. If we select simple_spinner_item , this is normal in the normal state, but when we want to change it, the lines are very narrow, not CheckedTextView , whereas in the usual spinner parameters - CheckedTextView . If you select simple_spinner_dropdown_item , the parameters have a CheckedTextView , but in the normal state they look different than in Fig.

(The first one is used by default, and the second one uses simple_spinner_dropdown_item ).

First one is default spinner and second one is using <code> simple_spinner_dropdown_item </code>

I want to show the spinner in the same way as by default. How to do it?

Android will accept the layout specified in the adapter and will use it for the control and elements unless you specify a view resource separately. By doing this, you can set the simple_item layout in the ArrayAdapter constructor, and then set the dropdown_item layout separately in the setDropDownViewResource () call.

 ArrayAdapter newAdapter = new ArrayAdapter(getApplicationContext(), android.R.layout.simple_spinner_item, new String[]{"Author","ISBN","Keyword","Title"}); newAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item); spinner_generalbooks.setAdapter(newAdapter);

If you want to customize the visualization of your Spinner, it will be easier for you to create your own component. Spinner is just a layout containing text, an image and a list in a popup window. Create your own layout for your element and use the new BaseAdapter object to bind your data.
