Needed Example of project showing all countries with flags and availability for getting countries mobile codes.
回答1:
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>
<string name="action_settings">Settings</string>
<string name="hello_world">Hello world!</string>

<item>967,YE</item>
<item>260,ZM</item>
<item>263,ZW</item>
</string-array>
</resources>
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).
