从一个意图传递一个长整型值到另一个 [英] passing a long value from one intent to another

问题描述

我试图从一个阶级的意图传递到另一个长期价值。但不知何故，我不似乎得到的语法或方法这样做。这样就解决了90％，我的问题。从MainActivity.java一个方法调用intentfunction（SETID）将其传递给在SelectOptions.java收到的意图。

I am trying to pass a long value from intent of one class to another. But Somehow I dont seem to get the syntax or method to do so. This would solve 90% of my problem. Passing it from a method called intentfunction(setid) in the MainActivity.java to a received intent in SelectOptions.java.

/ - MainActivity.java --- /

/--MainActivity.java---/

private void intentfunction(long setid)
{
     Intent intent = new Intent(this, SelectOptions.class);
     //editText = (EditText) findViewById(R.id.editText1);
     //editText = new EditText(this);
     etGWid.setText("");   //set the edit text to blank
    //String message = "TestHello";

    intent.putExtra(EXTRA_MESSAGE, setid);
    startActivity(intent);

}

像上面我希望实现。在这里，去Selectoptions.java的接收部分

SOmething like the above i wish to implement. And here goes the received part of Selectoptions.java

final Intent intent = getIntent();
    //String message = intent.getStringExtra(MainActivity.EXTRA_MESSAGE);
    long getid = intent.getLongExtra(MainActivity.EXTRA_MESSAGE, defaultValue)

这样的事情。

推荐答案

您已经正确地传递你的意图，现在在接收活动，让你可以使用捆绑的意图，

You have passed your intents correctly, now in the receiving activity to get the intent you could use bundles,

Bundle extras = getIntent().getExtras(); 
if (extras != null) {
    long getid = extras.getString('KEY',default_value);
}
