android - アクティビティ間でのデータの送信

Question

2つのアクティビティ間でデータを送信するにはどうすればよいですか？次のコードがありますがnull、レシーバーアクティビティにしかアクセスできません：

データを送信するアクティビティ：

Intent intent = new Intent(SecondScreen.this, ThirdScreen.class);
                intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);//clear previous activities
                intent.putExtra("CLIENT_ID", getUserID);
                intent.putExtra("PASSWORD", getUserPWD);
                startActivity(intent);

データを受け取りたいアクティビティ：

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_third_screen);
Bundle b = getIntent().getExtras(); 
    if (b != null)
    {
        CLIENT_ID =  b.getString("CLIENT_ID"); 
        CLIENT_PWD =  b.getString("PASSWORD"); 
    }

だから私は何が間違っているのですか？

ここでのUPD はLogCatです。

Answer 1

最近の活動

Intent intent = new Intent(Current.this, Next.class);
intent.putExtra("user", "admin");
intent.putExtra("pass", "123");
startActivity(intent);

次のアクティビティ

Intent intent = getIntent();
String user = intent.getExtras().getString("user");
String option = intent.getExtras().getString("pass");

Answer 2

に渡すときに文字列に値があると仮定してputExtra、以下のコードを確認します。同じように実行している場合は、他の場所で間違った結果が得られることを確認してください。

MainActivity.java

String getUserID="I am new bee";
 String getUserPWD="Let me google it";


 Intent intent = new Intent(MainActivity.this, SecondActivity.class);
         intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);//clear previous activities
         intent.putExtra("CLIENT_ID", getUserID);
         intent.putExtra("PASSWORD", getUserPWD);
         startActivity(intent);

SecondActivity.java

String CLIENT_ID="";
 String CLIENT_PWD="";

         Bundle b = getIntent().getExtras(); 
            if (b != null)
            {
                CLIENT_ID =  b.getString("CLIENT_ID"); 
                CLIENT_PWD =  b.getString("PASSWORD"); 
            }

            Log.d("^^^^^", "CLIENT_ID="+CLIENT_ID);
            Log.d("^^^^^", "CLIENT_PWD="+CLIENT_PWD);

出力：

03-10 10:30:59.946: D/^^^^^(10974): CLIENT_ID=I am new bee
03-10 10:30:59.946: D/^^^^^(10974): CLIENT_PWD=Let me google it

渡すときは文字列がnullであると確信しています。を呼び出すときは、単純に出力してくださいIntent。

Answer 3

2番目のアクティビティでは、次のようなことを行う必要があります。

if(getIntent().hasExtras("CLIENT_ID") && getIntent().hasExtras("PASSWORD"))
{
    getIntent().getStringExtra("CLIENT_ID");
    getIntent().getStringExtra("PASSWORD");
}

Answer 4

私はあなたの正確なコードとその動作を試しました..

両方のアクティビティにこの行を挿入し、ログをトレースして、CLIENT_IDとPASSWORDが最初と最初のアクティビティでNullでないことを確認します

Log.d（ "Your Data"、 "> >> >>" + CLIENT_ID + "//" + CLIENT_PWD）;

Answer 5

バンドルを渡すので、最初のアクティビティでこれを試す必要があります。

Intent intent = new Intent(SecondScreen.this, ThirdScreen.class);
Bundle bundle = new Bundle();
bundle.putString("CLIENT_ID", getUserID);
bundle.putString("PASSWORD", getUserPWD);
intent.putExtras(bundle);
startActivity(intent);
