如何通过一个2渔政数组作为android的意图额外 [英] how to pass a 2 dimention array as an intent extra in android

问题描述

我通过二维数组[] []对象作为一个额外的意图到另一个活动，但其显示的错误我不能确定我该怎么办？

 捆绑包= intent.getExtras（）;
     SmsMessage []封邮件= NULL;
     字符串str =;
      如果（捆绑！= NULL）
    {
        // ---检索收到的短信---
        [对象]的PDU =（对象[]）bundle.get（的PDU）;
        封邮件=新SmsMessage [pdus.length]
        的for（int i = 0; I＆LT; msgs.length;我++）{
            封邮件[I] = SmsMessage.createFromPdu（（字节[]）的PDU [I]）;
            STR + =短信来自+封邮件[I] .getOriginatingAddress（）;
            STR + =;
            STR + =封邮件[I] .getMessageBody（）的toString（）。
            STR + =\\ n;的String [] [] xmlResponse2 = NULL;
        的String [] =测试str.split（\\ n）;
        xmlResponse2 =新的String [0] [test.length];
        的for（int i = 0; I＆LT; test.length;我++）{
            xmlResponse2 [0] [I] =试验[Ⅰ];        }     目的L =新意图（背景下，AgAppMenu.class）;
        l.putExtra（msg中，xmlResponse2 [0] [I]）;
        l.setFlags（Intent.FLAG_ACTIVITY_NEW_TASK）;
            context.startActivity（升）;
 

解决方案

Intent.putExtra不接受2维数组按照下面的文档
http://developer.android.com/reference/android/content/Intent.html

我有检查Intent.putExtra源$ C ​​$ C，它使用捆绑类用于存储数据。

http://developer.android.com/reference/android/os/ Bundle.html

下面是Intent.java来源$ C ​​$ C

1. Intent.java <一个href=\"http://gitorious.org/android-eeepc/base/blobs/fda6fae156e31a287e3cfbf66e51ea1405cdf479/core/java/android/content/Intent.java\" rel=\"nofollow\">http://gitorious.org/android-eeepc/base/blobs/fda6fae156e31a287e3cfbf66e51ea1405cdf479/core/java/android/content/Intent.java


2. Bundle.java <一个href=\"https://github.com/android/platform_frameworks_base/blob/master/core/java/android/os/Bundle.java\" rel=\"nofollow\">https://github.com/android/platform_frameworks_base/blob/master/core/java/android/os/Bundle.java

Bundle.java使用的HashMap存储的内容，

我所知，它直接是不可能的。

您可以使用putParcelable方法，你需要创建自己的类的instanceof 2维数组。

一个快速的解决方案。

 的String []键= createKeys（）;
的String []值= createValues​​（）;（keys.length == values​​.length）bundle.putExtra（钥匙，键）;
bundle.putExtra（价值，价值）;
 

I pass 2d array [][] object as an intent extra to another activity, but its show error i can not be identifies what do i do?

     Bundle bundle = intent.getExtras();        
     SmsMessage[] msgs = null;
     String str = "";  
      if (bundle != null)
    {
        //---retrieve the SMS message received---
        Object[] pdus = (Object[]) bundle.get("pdus");
        msgs = new SmsMessage[pdus.length];            
        for (int i=0; i<msgs.length; i++){
            msgs[i] = SmsMessage.createFromPdu((byte[])pdus[i]);                
            str += "SMS from " + msgs[i].getOriginatingAddress();                     
            str += " :";
            str += msgs[i].getMessageBody().toString();
            str += "\n"; 

String[][] xmlResponse2= null;
        String[] test = str.split("\n");
        xmlResponse2= new String[0][test.length];
        for (int i = 0; i < test.length; i++) {
            xmlResponse2[0][i]=test[i];

        }

     Intent l = new Intent(context,AgAppMenu.class);
        l.putExtra("msg",xmlResponse2[0][i]);
        l.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);   
            context.startActivity(l);

解决方案

Intent.putExtra does not accept 2 dimension array as per the following document http://developer.android.com/reference/android/content/Intent.html

I have check the source code of Intent.putExtra , It use Bundle Class to store data

http://developer.android.com/reference/android/os/Bundle.html

Here is Source code of Intent.java

1. Intent.java http://gitorious.org/android-eeepc/base/blobs/fda6fae156e31a287e3cfbf66e51ea1405cdf479/core/java/android/content/Intent.java
2. Bundle.java https://github.com/android/platform_frameworks_base/blob/master/core/java/android/os/Bundle.java

Bundle.java use "HashMap" to store the content,

Best of my knowledge it's not possible directly

you can use putParcelable method, you need to create your own class instanceof 2 dimension array.

one quick solution

String[] keys = createKeys(); 
String[] values = createValues(); 

(keys.length == values.length) 

bundle.putExtra("keys", keys); 
bundle.putExtra("values", values);
