HashMapAdapter

This project provides a HashMapAdapter that seems to be missing from Android.

It can be used with a Spinner or AutoCompleteTextView to separate the data from the display text much like the HTML <OPTION> tag.

    mapData = new LinkedHashMap<String, String>();
    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");

    // autocomplete only examines the KEY while filtering
    acadapter = new LinkedHashMapAdapter<String, String>(this, android.R.layout.simple_list_item_1, mapData, LinkedHashMapAdapter.FLAG_FILTER_ON_KEY);

    // autocomplete only examines the VALUE while filtering
    // acadapter = new LinkedHashMapAdapter<String, String>(this, android.R.layout.simple_list_item_1, mapData, LinkedHashMapAdapter.FLAG_FILTER_ON_VALUE);

    // autocomplete examines the KEY or VALUE while filtering
    // acadapter = new LinkedHashMapAdapter<String, String>(this, android.R.layout.simple_list_item_1, mapData, LinkedHashMapAdapter.FLAG_FILTER_ON_KEY | LinkedHashMapAdapter.FLAG_FILTER_ON_VALUE);


    // fill in the EditText with the VALUE when an item is selected (default KEY)
    // acadapter = new LinkedHashMapAdapter<String, String>(this, android.R.layout.simple_list_item_1, mapData, LinkedHashMapAdapter.FLAG_FILTER_ON_KEY | LinkedHashMapAdapter.FLAG_FILTER_RESULT_USE_VALUE);

    autocomplete = (AutoCompleteTextView) findViewById(R.id.autocomplete);
    autocomplete.setAdapter(acadapter);
