커스텀 스피너 (Custom Spinner)

1. 레이아웃 추가

<Spinner     android:id="@+id/simpleSpinner"     android:layout_width="wrap_content"     android:layout_height="wrap_content"     android:layout_centerHorizontal="true" />

2. custom_spinner_items.xml 레이아웃 생성

<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"     android:layout_width="match_parent"     android:layout_height="wrap_content"     android:orientation="horizontal">     <ImageView         android:id="@+id/imageView"         android:layout_width="50dp"         android:layout_height="50dp"         android:padding="5dp"         android:src="@drawable/ic_launcher" />     <TextView         android:id="@+id/textView"         android:layout_width="fill_parent"         android:layout_height="wrap_content"         android:layout_gravity="center"         android:text="Demo"         android:textColor="#000" /> </LinearLayout>

3. 스피너 추가할 화면의 java 파일

public class MainActivity extends AppCompatActivity implements AdapterView.OnItemSelectedListener{     String[] countryNames={"India","China","Australia","Portugle","America","New Zealand"};     int flags[] = {R.drawable.india, R.drawable.china, R.drawable.australia, R.drawable.portugle, R.drawable.america, R.drawable.new_zealand};     @Override     protected void onCreate(Bundle savedInstanceState) {         super.onCreate(savedInstanceState);         setContentView(R.layout.activity_main);         Spinner spin = (Spinner) findViewById(R.id.simpleSpinner);         spin.setOnItemSelectedListener(this);         CustomAdapter customAdapter=new CustomAdapter(getApplicationContext(),flags,countryNames);         spin.setAdapter(customAdapter);     }     @Override     public void onItemSelected(AdapterView<?> arg0, View arg1, int position,long id) {         Toast.makeText(getApplicationContext(), countryNames[position], Toast.LENGTH_LONG).show();     }     @Override     public void onNothingSelected(AdapterView<?> arg0) {         // TODO Auto-generated method stub     } }

4. CustomAdapter.java 생성

import android.content.Context; import android.view.LayoutInflater; import android.view.View; import android.view.ViewGroup; import android.widget.BaseAdapter; import android.widget.ImageView; import android.widget.TextView; public class CustomAdapter extends BaseAdapter {     Context context;     int flags[];     String[] countryNames;     LayoutInflater inflter;     public CustomAdapter(Context applicationContext, int[] flags, String[] countryNames) {         this.context = applicationContext;         this.flags = flags;         this.countryNames = countryNames;         inflter = (LayoutInflater.from(applicationContext));     }     @Override     public int getCount() {         return flags.length;     }     @Override     public Object getItem(int i) {         return null;     }     @Override     public long getItemId(int i) {         return 0;     }     @Override     public View getView(int i, View view, ViewGroup viewGroup) {         view = inflter.inflate(R.layout.custom_spinner_items, null);         ImageView icon = (ImageView) view.findViewById(R.id.imageView);         TextView names = (TextView) view.findViewById(R.id.textView);         icon.setImageResource(flags[i]);         names.setText(countryNames[i]);         return view;     } }
