为什么长期的价值没有通过意图呢?
原标题:Why isnt the long value being passed through the intent?

Umm, 我试图通过一个从日历视图中提取的长线, 使用 GetDate () 方法, 并将其设置为长和长。 它对于一个按钮有效, 我在同一界面中有一个复式按钮, 对于第一个按钮有效, 但对于 hte 发送一个 MIME, 因为数据没有通过 : S :

 //THis one passes the long without any issues
Create = (Button) findViewById(R.id.CreateApp);
        Create.setOnClickListener(new OnClickListener() {

            public void onClick(View arg0) {
                finish();

                 long date = Present.getDate();
                Intent Crea = new Intent(getApplicationContext(),CreateAppointment.class);
                Crea.putExtra("SelectedDate", date);
                startActivity(Crea);
            }

    });

/ 重新进入另一类时的代码

Intent g = getIntent();
final long SDate = g.getLongExtra("SelectedDate", 0);


       //THE PROBLEM ONE :S
       Edit = (Button) findViewById(R.id.VEditApp);
       Edit.setOnClickListener(new OnClickListener() {

            public void onClick(View arViewg0) {
                finish();

                 long date = Present.getDate();
                Intent EDT = new Intent(getApplicationContext(),viewedit.class);
                EDT.putExtra("EDTDate", date);
                startActivity(EDT);
            }

    });

/ WHAT I 用来在另一类中收留

Intent EditRecieve = new Intent();
        long Cur_Date = EditRecieve.getLongExtra("EDTDate", 2);

有人能告诉我为什么我得不到这个价值, 为什么默认值会一直被传递吗?

最佳回答

在你写到的无效的例子中:

Intent EditRecieve = new Intent();
long Cur_Date = EditRecieve.getLongExtra("EDTDate", 2);

但在你的第一个成功的例子中 你写道:

Intent g = getIntent();
final long SDate = g.getLongExtra("SelectedDate", 0);

所以看起来像一个简单的打字, 将“ 新的意图 () ” 替换为“ get Intent () ”, 您应该表现良好 。

问题回答

在您调用新活动 : : : : :

//THis one passes the long without any issues
Create = (Button) findViewById(R.id.CreateApp);
        Create.setOnClickListener(new OnClickListener() {

            public void onClick(View arg0) {


                 long date = Present.getDate();
                Intent Crea = new Intent(getApplicationContext(),CreateAppointment.class);
                Crea.putExtra("SelectedDate", date);
                startActivity(Crea);
                 finish();
            }

    });

/ 返回其他类时的代码

Intent g = getIntent();
final long SDate = g.getLongExtra("SelectedDate", 0);


   //THE PROBLEM ONE :S
   Edit = (Button) findViewById(R.id.VEditApp);
   Edit.setOnClickListener(new OnClickListener() {

        public void onClick(View arViewg0) {



            Intent EDT = new Intent(getApplicationContext(),viewedit.class);
            EDT.putExtra("EDTDate", SDate );
            startActivity(EDT);
            finish();
        }

});

/ WHAT I 用来在另一类中收留

 Intent EditRecieve = new Intent();
    long Cur_Date = EditRecieve.getLongExtra("EDTDate", 2);
