我的菜单xml代码menu.xml:

<?xml version="1.0" encoding="utf-8"?><menu xmlns:android="http://schemas.android.com/apk/res/android">
<!-- Single menu item 
     Set id, icon and Title for each menu item
-->

 <item android:id="@+id/back"
      android:icon="@drawable/back1"
        android:showAsAction="never"
      android:title="Back" />

<item android:id="@+id/My_Profile"
      android:icon="@drawable/myprofile"
       android:showAsAction="never"
      android:title="My Profile" />

<item android:id="@+id/Job_Alert"
      android:icon="@drawable/jobalert4"
       android:showAsAction="never"
      android:title="Job Alert !" />

<item android:id="@+id/saved_job"
      android:icon="@drawable/jobapplied"
      android:title="Saved Jobs"
       />


<item android:id="@+id/Logout"
      android:icon="@drawable/logout"
      android:title="Logout" /> 
</menu>

我正在调用这样的菜单xml

     PopupMenu popup = new PopupMenu(getBaseContext(), v);
 popup.getMenuInflater().inflate(R.menu.menu,  popup.getMenu());
     popup.show();

但它没有显示图标.

如何在弹出菜单上设置图标？

我有一个列表视图,每行有两个文本视图和一个编辑文本,列表视图setOnItemClickListener()不起作用.

这里是我的Java代码.

public class CreateChallan extends Activity {


ListView lstCreate;

String[] strmainItemCode;
String[] strItem;
String[] strQuantity;
Context context=this;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.createchallan);
    lstCreate= (ListView) findViewById(R.id.createlist);
    lstCreate.setChoiceMode(AbsListView.CHOICE_MODE_MULTIPLE);

    strmainItemCode= new String[]{"555551","255555","355555","455555","555555"};

    strItem =new String[]{"A","B","C","D","F"};

    strQuantity =new String[]{"100","200","30","400","500"};

    CreateAdapter adapter= new CreateAdapter(this, strmainItemCode, strItem, s trQuantity);

    lstCreate.setAdapter(adapter);

    lstCreate.setOnItemClickListener(new AdapterView.OnItemClickListener() {

        @Override
        public void onItemClick(AdapterView<?> parent, View view,
                                int position1, long id) {
            // TODO Auto-generated method stub

            Toast.makeText(context, "Position",   Toast.LENGTH_LONG).show();

        }
    });
}







// Create List Adapter

class CreateAdapter …

我的Java代码更新数据库表

String qq="UPDATE ChallanItems SET Recieve ="+str+" WHERE ItemNo = "+code;
                    Log.d("Qry", qq);
                     myDbHelper.updatequery(qq);

updatequery方法

public void updatequery(String qry)
    {
        Cursor c = myDataBase.rawQuery(qry, null);


        Log.d("Up", ""+c.getCount());
    }

当我更新数据库时,计数返回0并且表未更新

我正在使用这个但是没有工作

String qq="UPDATE ChallanItems SET Recieve ="+str+" WHERE ItemNo = "+"'"+code+"'";

请帮助我如何解决这个问题

提前致谢
