Android的：问题OnItemClickListener [英] Android: Problem with OnItemClickListener

问题描述

我是初学者Android开发者。我试图创建一个SMS应用。

I am a beginner Android developer. I am trying to create an SMS application.

我创建了一个 TabHost 三 TabSpect（ListView控件，ListView中，TextView的）它打印我收件箱，发送和的TextView 它打印一些有用的信息。

I have created a TabHost with three TabSpect(ListView,ListView,TextView) which prints me INBOX, Send and in TextView it prints some useful information.

现在，如果我想点击任何项目的ListView ，它会打开短信管理器，它会充满了 phoneNumber的我点击了短信。

Now if I am trying to click on any item in ListView, it will open the SMS manager, where it will be filled with the phoneNumber of the SMS I clicked.

每次我尝试这个，我收到一个错误。

Every time I try this I receive an error.

list1.setOnItemClickListener(new OnItemClickListener() {
@Override
  public void onItemClick(AdapterView<?> arg, View view, int position,long id) {

    Uri uriSMSURIs = Uri.parse("content://sms/inbox");
    String pos = String.valueOf(position);
    Log.d(TAG, "value: " + pos);
    Cursor c = getContentResolver().query(uriSMSURIs, null, pos, null, null);

    Log.e(TAG, "value: " + c);
    String phoneNumber  = c.getString(c.getColumnIndex("address"));
    Log.e(TAG, "Value: " + phoneNumber;

    Intent sendIntent = new Intent(Intent.ACTION_VIEW);
    sendIntent.putExtra("address", phoneNumber);
    sendIntent.setType("vnd.android-dir/mms-sms");
    startActivity(sendIntent);
  }
});

POS 将返回所选项目的位置，但如果我使用 POS 在

pos is returning the position of the selected item but if I use pos in

Cursor c = getContentResolver().query(uriSMSURIs, null, pos, null, null); 

它抛出这个错误：

it throws this error:

7月4日至2日：53：15.504：ERROR / SMSManager（328）：值：android.content.ContentResolver$CursorWrapperInner@43e2b800

04-02 07:53:15.504: ERROR/SMSManager(328): value: android.content.ContentResolver$CursorWrapperInner@43e2b800.

我不知道如果我能做到这一点这样的。

I dont know if I can do that this way.

推荐答案

我觉得你传递给查询参数是错误的类型。试试这个：

I think the parameters you're passing to the query are the wrong types. Try this:

long id = arg.getItemIdAtPosition(position);
Cursor c = getContentResolver().query(uriSMSURIs, null, "_id = ?", new String[]{Long.toString(id)}, null);
