这是我的MainActivity.java

This is my MainActivity.java

public class MainActivity extends Activity implements OnClickListener
{
  private ImageView Msg;
  private ImageView Home;
  ListView listviewsms;
  private ArrayAdapter<String> adapter;

@Override
protected void onCreate(Bundle savedInstanceState)
{
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    Msg = (ImageView) findViewById(R.id.createmessage);
    Msg.setOnClickListener(this);

    Home = (ImageView) findViewById(R.id.home);
    Home.setOnClickListener(this);

    listviewsms = (ListView) findViewById(R.id.lvSMS);

    final List<String> msgList = getSMS();
    adapter = new ArrayAdapter<String>(this, R.layout.conversation_list,R.id.name,msgList); 

    // updating listview
    listviewsms.setAdapter(adapter);
   }

   public ArrayList<String> getSMS()
   {
    ArrayList<String> sms = new ArrayList<String>();
    Uri uriSMSURI = Uri.parse("content://sms/inbox");

    Cursor cursor = getContentResolver().query(uriSMSURI, String[] {"*"}, null, null, "date desc");

    while (cursor.moveToNext()) 
    {
        String address = cursor.getString(cursor.getColumnIndex("address"));
        String body = cursor.getString(cursor.getColumnIndexOrThrow("body"));
        String read = cursor.getString(cursor.getColumnIndexOrThrow("read"));           

        //to fetch the contact name of the conversation
        String contactName = address;
        Uri Nameuri = Uri.withAppendedPath(PhoneLookup.CONTENT_FILTER_URI, Uri.encode(address));  
        Cursor cs= getContentResolver().query(Nameuri, new String[]{PhoneLookup.DISPLAY_NAME},PhoneLookup.NUMBER+"='"+address+"'",null,null);

        if(cs.getCount()>0)
        {
            cs.moveToFirst();
            contactName = cs.getString(cs.getColumnIndex(PhoneLookup.DISPLAY_NAME));
        }           
        sms.add(contactName + "\n"+body);

     }

    for (int i = 0; i < sms.size(); i++) 
    {
        Log.e(" "," "+sms.get(i));
    }

    return sms;
    }
     public void onClick(View v) 
    {
        //button functionality
    }
 }

我该如何解决这个问题。
请帮忙。
谢谢！

How do I resolve this. Please Help. Thanks!

推荐答案

有关三星手机，你需要使用这个URI Uri.parse（内容：//彩信，短信/通话简单=真）;

For samsung phones you need to use this uri Uri.parse("content://mms-sms/conversations?simple=true");

和不通过空作为投影。

添加新的String [] {*} 作为投影。
