Question

I am developing an app where i need to set spinner values dynamically based on previous screen values. My code…

Main.java.

String[] values = {"All","Only Walk-in","Only Phone","Only Web","Walkin-phone","Walkin-web","phone-web"};

 /*ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_dropdown_item,apttypes);
    spinner.setAdapter(adapter);*/

But here what i want is from previous screen i am getting some value (like spinner postion). based on that i need to set spinner value to display…

Means from previous screen if i got values =0 means,

i need to set spinner value to display “All” from values array at top.

If i got value= 5 means,

i want to set spinner value to display as “Walkin-web”

How can i do that. can anyone help me with this…

Answer 1

Pass the value in from the previous Activity using extras in the Intent you use to launch it. Then when you’ve read the value call

int position = getIntent().getIntExtra( "name", defaultValue );
spinner.setSelection( position );

Which will move the spinner to the index you selected.
