ComboBox

Combination of Spinner and EditText. Android 4.4+ (API 19)

Usage

For example usages, see the sample app in the app/ folder.

Add Jitpack to repositories in build.gradle and add ComboBox dependency to dependencies:

repositories {
    // your other repos...
    jcenter()
    maven { url "https://jitpack.io" }
}

dependencies {
    // your other deps...
    implementation 'com.github.mc0239:ComboBox:v1.0.0'
}

Include ComboBox widget in your layout

<com.mc0239.combobox.ComboBox
    android:id="@+id/comboBox2"
    android:layout_width="match_parent"
    android:layout_height="wrap_content" />

3.a. Add an adapter to ComboBox using resource arrays:

ComboBox comboBox1 = findViewById(R.id.comboBox1);
ComboBoxAdapter adapter1 = ComboBoxAdapter
        .createFromResources(this, R.array.server_entries_array, R.array.server_values_array);
comboBox1.setAdapter(adapter1);

To create a custom entry in array, leave an empty <item/> tag in values array:

<string-array name="server_entries_array">
    <item>Germany</item>
    <item>UK</item>
    <item>USA</item>
    <item>Other</item> <!-- entry name for custom entry -->
</string-array>
<string-array name="server_values_array">
    <item>http://www.example.de/</item>
    <item>http://www.example.co.uk/</item>
    <item>http://www.example.com/</item>
    <item /> <!-- this is "custom" entry -->
</string-array>

3.b. Or add an adapter to ComboBox using List<Pair<String, String>> arrays:

ArrayList<Pair<String, String>> list = new ArrayList<>();
list.add(new Pair<>("Entry 1", "value1"));
list.add(new Pair<>("Entry 2", "value2"));
...
list.add(null); // this is your "custom" entry
...

ComboBox comboBox2 = findViewById(R.id.comboBox2);
ComboBoxAdapter adapter2 = new ComboBoxAdapter(this, list, "Custom value:");
comboBox2.setAdapter(adapter2);

(Optional) Customize EditText input and/or listen for selected item changes:

// EditText hint and input type
comboBox2.setHint("value x");
comboBox2.setInputType(InputType.TYPE_TEXT_FLAG_NO_SUGGESTIONS);

comboBox2.setOnValueChangedListener(new ComboBox.OnValueChangedListener() {
        @Override
        public void onValueChanged(String value, boolean isCustom) {
            textView.setText(String.format("Selected item: %s [isCustom? %s]", value, isCustom));
        }
});

Using as a preference

You can use ComboBox as a preference on a PreferenceScreen

<com.mc0239.combobox.ComboBoxPreference
    android:title="Choose server"
    android:key="server"
    app:entries="@array/server_entries_array"
    app:entryValues="@array/server_values_array"
    android:defaultValue="http://www.example.co.uk/"
    android:hint="http://example.com/"
    android:inputType="textUri" />

Note: app:entries and app:entryValues must be set!
