    <?xml version="1.0" encoding="utf-8"?>
    <resources>
    <string-array name="type">
        <item>Select Type</item>
        <item >Color</item>
        <item >Weeks</item>
      </string-array>

    <string-array name="color">
        <item>Blue</item>
        <item >Orange</item>
        <item >Red</item>
        <item >Green</item>
       </string-array>

     <string-array name="weeks">
        <item>Sunday</item>
        <item >Monday</item>
        <item >Tuesday</item>
        <item >Wednesday</item>
              </string-array>

</resources>

  <TextView
  android:layout_width="fill_parent"
  android:layout_height="wrap_content"
  android:text="Select Type:"/>

  <Spinner
  android:id="@+id/spinner"
  android:layout_width="fill_parent"
  android:layout_height="wrap_content"
  android:prompt="@string/spinner_title"
  android:drawSelectorOnTop = "true"/>


    <Spinner
    android:id="@+id/spinner1"
    android:layout_width="match_parent"
          android:prompt="@string/spinner_title1"
    android:layout_height="wrap_content" />

    ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(
            this, R.array.type, android.R.layout.simple_spinner_item);

    adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
    spinner.setAdapter(adapter);

In this two spinners, in first spinner, i have used "type", based on the selection of type of first spinner, how to change second spinner to use the array color and weeks?

Answer 1

in first spinner OnItemSelectedListener do below way..

spinner1.setOnItemSelectedListener(new OnItemSelectedListener() {

            public void onItemSelected(AdapterView<?> parentView,
                    View selectedItemView, int position, long id) {
                // Object item = parentView.getItemAtPosition(position);

                // Depend on first spinner value set adapter to 2nd spinner
            if(pos == 1){
              spinner2.setAdapter(adapter2);
            }else{
              spinner2.setAdapter(adapter3);
            } 

            }

            public void onNothingSelected(AdapterView<?> arg0) {// do nothing
            }

        });
