Answer 1

I created an HashMap adapter for use in these scenarios. Also see example project here

    mapData = new LinkedHashMap();

    mapData.put("shamu", "Nexus 6");
    mapData.put("fugu", "Nexus Player");
    mapData.put("volantisg", "Nexus 9 (LTE)");
    mapData.put("volantis", "Nexus 9 (Wi-Fi)");
    mapData.put("hammerhead", "Nexus 5 (GSM/LTE)");
    mapData.put("razor", "Nexus 7 [2013] (Wi-Fi)");
    mapData.put("razorg", "Nexus 7 [2013] (Mobile)");
    mapData.put("mantaray", "Nexus 10");
    mapData.put("occam", "Nexus 4");
    mapData.put("nakasi", "Nexus 7 (Wi-Fi)");
    mapData.put("nakasig", "Nexus 7 (Mobile)");
    mapData.put("tungsten", "Nexus Q");

    adapter = new LinkedHashMapAdapter(this, android.R.layout.simple_spinner_item, mapData);
    adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);

    spinner = (Spinner) findViewById(R.id.spinner);
    spinner.setAdapter(adapter);
    spinner.setOnItemSelectedListener(this);
