解决方案

我假设你的 getSMS()不返回任何东西。您可以通过此行之后加入一些调试code检查:

 名单,其中,字符串> msgList = getSMS();
 

类似于

  Log.d(yourTag,项目数:.msgList->尺寸());
 

看来,它不返回任何东西。有没有抓到任何例外:您可以通过调试特定功能的开始?添加一些记录一看就知道。也许你没有添加正确的线路在你的清单

 <使用-权限的Andr​​oid:名称=android.permission.READ_SMS/>
 

还是其他什么东西出了问题该函数。你把它写自己,或者是它的一个副本?

Hello i am trying to create SMS aplication witch shows me SMS Inbox in ListView.But if i open this aplication there is no action.I can see only black screen with name of aplication :( .Can somebody check my source code and tell me where is the problem? Thank you.

There is source code:

package sms.five;

import java.util.ArrayList;
import java.util.List;
import android.app.Activity;
import android.database.Cursor;
import android.net.Uri;
import android.os.Bundle;
import android.telephony.SmsManager;
import android.view.View;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.ArrayAdapter;
import android.widget.ListView;
import android.widget.TextView;

public class Smsfive extends Activity {
    /** Called when the activity is first created. */
    public void onCreate(Bundle savedInstanceState, ListView messages) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        ListView list = (ListView) findViewById(R.id.list);

        List<String> msgList = getSMS();

        for(int i = 0; i<msgList.size(); i++) {
            System.out.println(msgList.get(i));
       }
        ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,R.layout.main, msgList); 
        list.setAdapter(adapter);
        list.setOnItemClickListener(new OnItemClickListener()
       {
        @Override
    public void onItemClick(AdapterView<?> parent, View view, int position,long id) {
         SmsManager m = SmsManager.getDefault();
         String destinationNumber=(String) ((TextView)view).getText();              
         m.sendTextMessage(destinationNumber, null, destinationNumber, null, null);

       }          
         });
       }

    public List<String> getSMS() {      
        List<String> list = new ArrayList<String>();
        Uri uri = Uri.parse("content://sms/inbox");
        Cursor c = null;
        try{
            c = getApplicationContext().getContentResolver().query(uri, null, null ,null,null); 
        }catch(Exception e){
            e.printStackTrace();
        }
        try{
            for (boolean hasData = c.moveToFirst(); hasData; hasData = c.moveToNext()) {
                final String address = c.getString(c.getColumnIndex("address"));
                final String body = c.getString(c.getColumnIndexOrThrow("body"));
                list.add("Number: " + address + " .Message: " + body);
            }
        }catch(Exception e){
            e.printStackTrace();
        }
     c.close(); 
     return list;
    }
}

XML File(main.xml):

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
android:id="@+id/widget30"
android:layout_width="fill_parent"
android:layout_height="fill_parent"

<ListView

</ListView>
</LinearLayout>

        </activity>

    </application>


<uses-permission android:name="android.permission.READ_SMS"></uses-permission>
</manifest> 

解决方案

I'm assuming your getSMS() is not returning anything. You can check this by adding some debugging code after this line:

List<String> msgList = getSMS();

Something like

Log.d("yourTag","number of items: ".msgList->size());

It seems that it doesn't return anything. You might start by debugging that particular function: are there any exceptions caught? add some logging to see that. Maybe you didn't add the correct line in your manifest

 <uses-permission android:name="android.permission.READ_SMS"/>

Or something else goes wrong in that function. Did you write it yourself, or was it a copy?
