Super Spinner

Custom android view to replace standard spinner.

It gives you filtering options for any adapter and data source you use. There is also default state with nothing selected.

Adding to your project

In your top-level build.gradle add line

allprojects {
    repositories {
        jcenter()
        maven { url "https://jitpack.io" } //<==line to add
    }
}

In your app-module-level build.gradle add

android {
    ....
}
dependencies {
    compile 'com.github.tomasz-m:filterspinner:1.4.1' //<==line to add
}

You can of course build whole project from this repo (with example how to use it).

Using

Add to your layout..

<info.tomaszminiach.superspinner.SuperSpinner
    style="@style/Base.Widget.AppCompat.Spinner.Underlined"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:id="@+id/superSpinner"/>

... find in your Activity/Fragment/View ...

final SuperSpinner superSpinner = (SuperSpinner) findViewById(R.id.superSpinner);

... and eventually do some configuraion

//its a good idea to set the hint view with same layout as in adapter
superSpinner.setHintView(android.R.layout.simple_list_item_1, android.R.id.text1," -please select- ");

You can set adpaters and listeners as for normal spinner

superSpinner.setAdapter(simpleAdapter);
superSpinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
    @Override
    public void onItemSelected(AdapterView<?> adapterView, View view, int i, long l) {
        Log.d("On Item Selected",superSpinner.getSelectedItem().toString());
    }
    @Override
    public void onNothingSelected(AdapterView<?> adapterView) {}
});

But you can also add the search feature if you add one of the following listeners (in this case you dont have to use the setAdapter(...):

• VERSION 1 - use for fast updates on the main thread

superSpinner.setFilterListener(new SuperSpinner.FilterListener() {
    @Override
    public ListAdapter onFilter(String text) {
        return new ArrayAdapter<String>(MainActivity.this,android.R.layout.test_list_item,dataProvider.getItems(text));
    }
});

• VERSION 2 - use for longer running filterings

superSpinner.setCallbackFilterListener(new SuperSpinner.CallbackFilterListener() {
    @Override
    public ListAdapter onFilter(String text, SuperSpinner.Callback callback) {
        //simulate long running operation
        handler.removeCallbacks(runnable);
        runnable = new MyRunnable(callback, dataProvider, text);
        handler.postDelayed(runnable, 1000);
        return null;
    }
});
