Pergunta

Parece que eu estou pedindo algo que tem sido feita no passado, mas ninguém conseguiu obter uma resposta, portanto, com os dedos cruzados.

Estou tentando implementar a o CountryPicker a partir do github.No entanto, ele parece não funcionar.Eu tinha tentado 2 3 maneiras possíveis para implementá-lo (pelo menos eu acho que houve 3).

Primeiro foi adicionar o CountryPicker código dentro da minha aplicação e no topo do que implementar o exemplo de código de pasta (nao funciona)
Segunda era, de alguma forma, alterar o código para fragmentactivity atividade (ainda não tentei isso ainda)
Um terceiro foi para importar o CountryPicker código como uma biblioteca.Eu acho que era o caminho certo para fazê-lo, por isso listei os passos que eu ter feito para fazê-lo funcionar.

Primeiro eu criei novo projeto android chamado CountryPickerApp e implementado o código da amostra de pasta encontrado dentro de que countrypicker repositório.Aqui está o código para MainActivity.class:

 package com.example.countrypickerapp;
 import android.os.Bundle;
 import android.support.v4.app.FragmentActivity;
 import android.support.v4.app.FragmentManager;
 import android.support.v4.app.FragmentTransaction;
 import android.view.Menu;
 import android.view.MenuItem;
 import android.view.MenuItem.OnMenuItemClickListener;
 import android.widget.Toast;

 import com.countrypicker.CountryPicker;
 import com.countrypicker.CountryPickerListener;

 public class MainActivity extends FragmentActivity {

  @Override
  protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    FragmentManager manager = getSupportFragmentManager();
    FragmentTransaction transaction = manager.beginTransaction();

    CountryPicker picker = new CountryPicker();
    picker.setListener(new CountryPickerListener() {

        @Override
        public void onSelectCountry(String name, String code) {
            Toast.makeText(
                    MainActivity.this,
                    "Country Name: " + name + " - Code: " + code
                            + " - Currency: "
                            + CountryPicker.getCurrencyCode(code),
                    Toast.LENGTH_SHORT).show();
        }
    });

    transaction.replace(R.id.home, picker);

    transaction.commit();

}

@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);
    MenuItem item = menu.findItem(R.id.show_dialog);
    item.setOnMenuItemClickListener(new OnMenuItemClickListener() {

        @Override
        public boolean onMenuItemClick(MenuItem item) {
            CountryPicker picker = CountryPicker.newInstance("Select Country");
            picker.setListener(new CountryPickerListener() {

                @Override
                public void onSelectCountry(String name, String code) {
                    Toast.makeText(
                            MainActivity.this,
                            "Country Name: " + name + " - Code: " + code
                                    + " - Currency: "
                                    + CountryPicker.getCurrencyCode(code),
                            Toast.LENGTH_SHORT).show();
                }
            });

            picker.show(getSupportFragmentManager(), "COUNTRY_PICKER");
            return false;
        }
    });
    return true;
}

}

Aqui está o código para o AndroidManifest.xml arquivo

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.countrypickerapp"
 android:versionCode="1"
 android:versionName="1.0" >

<uses-sdk
    android:minSdkVersion="8"
    android:targetSdkVersion="18" />

<application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >
    <activity
       android:name="com.example.countrypickerapp.Main1Activity"
        android:label="@string/app_name" android:parentActivityName="@string/title_activity_main1">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
    <activity
       android:name="com.example.countrypickerapp.MainActivity"
       android:label="@string/title_activity_main1" >
    </activity>
</application>

</manifest>

Pelo que entendi a pasta principal (CountryPicker) teve de ser importado como uma biblioteca assim que eu segui esses passos:

File->New->Other
Select Android Project
Select "Create Project from existing source"
Click "Browse..." button and navigate to johannilsson-android-actionbar\actionbar
Finish (Now action bar project in your workspace)
Right-click on your project -> Properties
In Android->Library section click Add
select recently added project -> Ok

E aqui está a lista de logcat log de erros:

Additonally eu adicionei um adicional de Atividade de chamado MainActivity1 que tem um botão que, quando clicado, redireciona para MainActivity onde CountryPicker é implementado.

Espero ter explicado o meu problema e irá obter uma solução, sugestão, dica ou qualquer coisa que pudesse me mais perto de chegar ao trabalho.Eu sei que eu poderia ter reimplementado tudo do zero, usando métodos diferentes, mas eu não consigo ver um ponto de reinventar algo que já foi implementado e enviado para a partilha, para além de aprender algo novo, é claro.

Solução

O manifesto declara Principal Atividade 1 (espaço adicionado para realçar o algarismo 1), mas o seu arquivo de classe é MainActivity.java sem o 1 !!:)
