Question

我想将普通短信发送到具有不同消息的多个号码。在这里，我已将电话号码和消息检索到列表视图。当我单击发送按钮时，它应该逐行读取该列表视图中的所有行，并且应该逐个发送消息。任何人都可以帮助我。我知道这个编码用于向一个号码发送消息。但我想在列表视图中发送多个号码。

String phoneNo = user_name.toString();
        String message = user_department.toString();
        try {
        SmsManager smsManager = SmsManager.getDefault();
        smsManager.sendTextMessage(phoneNo, null, message, null, null);
        Toast.makeText(getApplicationContext(), "SMS sent.",
        Toast.LENGTH_LONG).show();
        } catch (Exception e) {
        Toast.makeText(getApplicationContext(),
        "SMS faild, please try again.",
        Toast.LENGTH_LONG).show();
        e.printStackTrace();

这是我的列表数组适配器。

SQLiteDatabase db = dbhelper.getWritableDatabase();
        Cursor mCursor=db.rawQuery("SELECT * FROM contacts WHERE department='"+label+"'", null);

        userId.clear();
        user_name.clear();
        user_department.clear();
        if (mCursor.moveToFirst()) {
            do {
                userId.add(mCursor.getString(mCursor.getColumnIndex(DBhelper.CONTACTS_COLUMN_ID)));
                user_name.add(mCursor.getString(mCursor.getColumnIndex(DBhelper.CONTACTS_COLUMN_NAME)));
                user_department.add(mCursor.getString(mCursor.getColumnIndex(DBhelper.CONTACTS_COLUMN_DEPARTMENT)));

            } while (mCursor.moveToNext());
        }
        DisplayAdapter disadpt = new DisplayAdapter(home.this,userId, user_name, user_department);
        lv.setAdapter(disadpt);
        disadpt.notifyDataSetChanged();

        mCursor.close();

Answer 1

对于列表视图，数据由adapter保存。所以你必须循环通过适配器项来发送消息。

与以下代码类似

for(int i=0;i<adapter.getCount();i++){
   sendMsg(adapter.getItem(i).number);
}

此处Adapter，getItem返回给定位置的项目。我希望你有那个对象的电话号码。您希望发送消息的次数多次调用消息发送方法。： - /

Contract{

    String userName ;
    String userId ;
    String user_department ;
    String phoneNum ;
}



class DisplayAdapter extends BaseAdapter {

List<Contract> mDatas ;
DisplayAdapter(Context context, List<Contract> datas) {
    mDatas = datas ;
}

// ......
}



SQLiteDatabase db = dbhelper.getWritableDatabase();
    Cursor mCursor=db.rawQuery("SELECT * FROM contacts WHERE department='"+label+"'", null);

    List<Contract> datas = new ArrayList<Contract>();
    if (mCursor.moveToFirst()) {
        do {
            Contract newContract = new Contract();

            newContract.userId = mCursor.getString(mCursor.getColumnIndex(DBhelper.CONTACTS_COLUMN_ID));
            newContract.userName = mCursor.getString(mCursor.getColumnIndex(DBhelper.CONTACTS_COLUMN_NAME));
            newContract.user_department = mCursor.getString(mCursor.getColumnIndex(DBhelper.CONTACTS_COLUMN_DEPARTMENT));

            newContract.phoneNum = "set user's phone num";
            datas.add(newContract);
        } while (mCursor.moveToNext());
    }
    DisplayAdapter disadpt = new DisplayAdapter(Home.this, datas);
    lv.setAdapter(disadpt);
    disadpt.notifyDataSetChanged();

    mCursor.close();




    // button click  and send msg.

    for(Contract contractItem : datas) {
        // send sms code method

    }

Android逐行读取列表视图中的所有值
