Dependency

By Gradle:

dependencies {
    ...
    compile 'com.sherlockshi.widget:sherlockspinner:1.0.2'
}

or by Maven:

<dependency>
  <groupId>com.sherlockshi.widget</groupId>
  <artifactId>sherlockspinner</artifactId>
  <version>1.0.2</version>
  <type>pom</type>
</dependency>

Usage

1. use in xml files, just as system Spinner:

<com.sherlockshi.widget.SherlockSpinner
    android:id="@+id/sherlock_spinner"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    app:lineColor="#00FF00"
    android:gravity="center"
    android:hint="Please Select..."/>

SherlockSpinner has one additional attributes:
lineColor: set the bottom line color

As SherlockSpinner extends EditText, you can use other Attributes of EditText, such as gravity...

2. then use it just like system Spinner, set Adapter and ItemClickListener:

mSherlockSpinner = (SherlockSpinner) findViewById(R.id.sherlock_spinner);
ArrayAdapter<String> mAdapterLanguages = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, mLanguages);
mSherlockSpinner.setAdapter(mAdapterLanguages);
mSherlockSpinner.setOnItemClickListener(new AdapterView.OnItemClickListener() {
    @Override
    public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
        showMessage("Select " + mLanguages[position]);
    }
});

3. (Optional) If you want to refresh data asynchronously, you can use the click listener:

Remember:after you get data, you must manually call sherlockSpinner.show() to show dropdown item

mSherlockSpinner.setOnClickListener(new SherlockSpinner.OnClickListener() {
    @Override
    public void onClick(View v) {
        getDataFromNet();
    }
});

public void getDataFromNet() {
    // after delay 2s, modify the source data, to simulate net request
    new Thread(new Runnable() {
        @Override
        public void run() {
            try {
                Thread.sleep(2000);
            } catch (InterruptedException e) {
                e.printStackTrace();
            }

            mLanguages[4] = "Javaaaaaaaaaaa";
            mAdapterLanguages.notifyDataSetChanged();

            // then you must manually call sherlockSpinner.show()
            runOnUiThread(new Runnable() {
                @Override
                public void run() {
                    mSherlockSpinner.show();
                }
            });
        }
    }).start();
}

4. (Optional) more attributes

• As SherlockSpinner extends EditText, you can use other Attributes of EditText, such as gravity、textSize、textColor...
• SherlockSpinner has one more attribute，you can set It's position, ie anchorView：

mSherlockSpinner.setAnchorView(findViewById(R.id.llyt_anchor));

the difference is between Part3 and Part4 in the Gif picture:

• in Part3, dropdown list anchor in Spinner
• in Part4, dropdown list anchor in whole line
