java - 如何将 Uri 值传递给 bundle 值

Question

以下代码获取多个联系人并将它们存储在一个包中:

 Intent phonebookIntent = new Intent("intent.action.INTERACTION_TOPMENU");
    phonebookIntent.putExtra("additional", "phone-multi");
    phonebookIntent.putExtra("maxRecipientCount", MAX_PICK_CONTACT);
    phonebookIntent.putExtra("FromMMS", true);
    startActivityForResult(phonebookIntent, REQUEST_CODE_PICK_CONTACT);

下面的代码检索选定的数据:

  if (requestCode ==  REQUEST_CODE_PICK_CONTACT) {

            Uri contractData = data.getData();

            Bundle contantData =  data.getExtras();
            String result= contantData.getString("result");
            ArrayList<String> contacts = contantData.getStringArrayList("result");
            ContactRetriever cr = new ContactRetriever(getApplicationContext(), contacts);
            Person p = cr.getPerson();

我想要 Uri 中的数据，以便我可以在引用 Uri 数据的其他类中使用它。

如何将包值传递给 Uri 数据？

另一个使用 Uri 数据作为“contactData”的例子:

private String getNumber() {
    String ret = null;


    Cursor cId = cr.query(contractData, new String[]{ContactsContract.Contacts._ID}, null, null, null);

    if (cId.moveToFirst()){
        id = cId.getString(cId.getColumnIndex(ContactsContract.Contacts._ID));
        Log.i(TAG + " IDs: ", id);
    }
    cId.close();

    Cursor cNum = cr.query(contractData, null, null, null, null);

    if (cNum.moveToNext()){
        ret = cNum.getString(cNum.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
        Log.i(ret, TAG + " NUMBERS: ");
    }
    return ret;
}

private String getName() {
    String ret = null;

    Cursor c = cr.query(contractData, null, null, null, null);
    if (c.moveToFirst())
        ret = c.getString(c.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));

    c.close();
    Log.i(TAG + "NAMES: ", ret);
    return ret;
}

contractData的具体用法示例:

Cursor cId = cr.query(contractData, new String[]{ContactsContract.Contacts._ID}, null, null, null);

Cursor cNum = cr.query(contractData, null, null, null, null);

Cursor c = cr.query(contractData, null, null, null, null);

Uri 实现了 Parcelable 所以你可以这样做:

phonebookIntent.putExtra("uri", your_uri_object);

回读:

Uri uri =  getIntent().getParcelableExtra("uri");
