Needed Example of project showing all countries with flags and availability for getting countries mobile codes.
You can download the project from here.
We need files with codes described below.
class MainActivity
package com.example.countrieswithflags;
import android.app.Activity;
import android.os.Bundle;
import android.view.Menu;
import android.widget.ListView;
public class MainActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
String[] recourseList=this.getResources().getStringArray(R.array.CountryCodes);
final ListView listview = (ListView) findViewById(R.id.listView);
listview.setAdapter(new CountriesListAdapter(this, recourseList));
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
}
We need adapter for list
CountriesListAdapter
package com.example.countrieswithflags;
import java.util.Locale;
import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.ImageView;
import android.widget.TextView;
public class CountriesListAdapter extends ArrayAdapter<String> {
private final Context context;
private final String[] values;
public CountriesListAdapter(Context context, String[] values) {
super(context, R.layout.country_list_item, values);
this.context = context;
this.values = values;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
LayoutInflater inflater = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View rowView = inflater.inflate(R.layout.country_list_item, parent, false);
TextView textView = (TextView) rowView.findViewById(R.id.txtViewCountryName);
ImageView imageView = (ImageView) rowView.findViewById(R.id.imgViewFlag);
String[] g=values[position].split(",");
textView.setText(GetCountryZipCode(g[1]).trim());
String pngName = g[1].trim().toLowerCase();
imageView.setImageResource(context.getResources().getIdentifier("drawable/" + pngName, null, context.getPackageName()));
return rowView;
}
private String GetCountryZipCode(String ssid){
Locale loc = new Locale("", ssid);
return loc.getDisplayCountry().trim();
}
}
Our strings.xml will have this lines
<?xml version="1.0" encoding="utf-8"?>
<resources>
<string name="app_name">Countries With Flags</string>

in layout we must have country_list_item.xml
<?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="match_parent"
android:orientation="horizontal" >
<ImageView
android:id="@+id/imgViewFlag"
android:layout_height="11px"
android:layout_width="16px"
android:layout_margin="5dp" />
<TextView
android:id="@+id/txtViewCountryName"
android:layout_height="wrap_content"
android:layout_width="wrap_content" />
</LinearLayout>
and activity_main.xml
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context=".MainActivity" >
<ListView
android:id="@+id/listView"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:layout_marginTop="15dp" >
</ListView>
</RelativeLayout>
Also You can find images of flags with correct names (iso names of countries) from here. Or You can find them in the project(link given above).
