java.lang.NullPointerException long baba1

Question

我正在将 long 值和 String 值作为附加值从列表 Activity 发送到 agenmin Activity 。但是在 第120行

    long baba1 = intent1.getExtras().getLong("baba",0); //line number 120

从列表 Activity 发送

          // long id from from listview

            Intent i = new Intent(list.this, agenmin.class);
            i.putExtra("baba", id);
            startActivity(i); 

             //int position from listview
            String c= Integer.toString(position);
            Intent i1 = new Intent(list.this, agenmin.class);
            i1.putExtra("abc", c);
            startActivity(i1); 

在接收方agenmin

            Intent i1 = getIntent();
        String easyPuzzle;
        easyPuzzle=i1.getStringExtra("abc");
        textView2.setText(easyPuzzle);

        Toast.makeText(getApplicationContext(), "Position " + (mess)+" ROWID " +(easyPuzzle), Toast.LENGTH_LONG).show();


           Intent intent1 = getIntent();
        long baba1 = intent1.getExtras().getLong("baba",0);
        String strLong1 = Long.toString(baba1);
        textView3.setText(strLong1);

Logcat:

      05-27 20:43:45.169: E/AndroidRuntime(593): FATAL EXCEPTION: main

我启动了 agenmin Activity 两次，这就是 第 120 行处出现“java.lang.NullPointerException”的原因

Answer 1

试试这个:

PendingIntentintent1 = PendingIntent.getActivity(上下文，0， Intent ，
PendingIntent.FLAG_UPDATE_CURRENT);
