私は現在、ユーザー情報を管理できるAndroidアプリを開発中です。そのために私は登録フォーム（名前、ユーザー名、電子メールとパスワード）を持っていて、ロギング後、私のアプリはトースト（ 'ようこそ "ユーザー名"'）を表示します。そして今私はいくつかの問題を抱えています...ユーザーがメールアドレス、ユーザー名、パスワードなどの情報を更新できるようにする方法を知らない。私は、ユーザーが自分の情報を更新したい私のLoginActivity.java私UserAreaActivity.javaログイン後のユーザー情報の編集/更新[Android]
public class UserAreaActivity extends Activity {
public ImageView bgNet;
public ImageView bgChat;
public ImageView bgStats;
public ImageView bgGo;
public Button bLogout;
TextView name;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE); // Enlever la barre bleue
setContentView(R.layout.activity_user_area);
name = (TextView) findViewById(R.id.name);
Bundle bundle = getIntent().getExtras();
if (bundle != null)
{
name.setText(" "+bundle.getString("name"));
}
else
{
name.setText("Ajanthan");
}
initGoHome();
initPlay();
initGoStats();
initGoChat();
buttonLogout();
}
@Override
public void onBackPressed() {
return;
}
private void initGoHome() {
bgNet = (ImageView) findViewById(R.id.bgNet);
bgNet.setOnClickListener(new View.OnClickListener() {
