dialog_edit_text.xml如下：

    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content">

            android:layout_width="fill_parent" android:layout_height="wrap_content"
        android:text="@string/str_info_na"
        android:layout_marginTop="8dip"
        android:layout_marginBottom="8dip"
        android:layout_marginLeft="8dip"
        android:layout_marginRight="8dip">
   

            android:layout_width="fill_parent" android:layout_height="wrap_content"
        android:singleLine="true"
        android:layout_marginBottom="8dip"
        android:layout_marginLeft="8dip"
        android:layout_marginRight="8dip">
       
   

            android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:padding ="6px"
        android:background="#ffffff">

                    android:layout_width="120px" android:layout_height="wrap_content"
            android:text="@string/str_ok"
            android:layout_alignParentLeft="true" />

       

            android:layout_width="120px" android:layout_height="wrap_content"
            android:text="@string/str_cancel"
            android:layout_alignParentRight="true" />

   

 

 

 

 

 

 

通常使用的SetView（view）会显示如下效果

   

   LayoutInflater factory = LayoutInflater.from(m_activity);
    final View textEntryView = factory.inflate(R.layout.dialog_edit_text, null);

    EditText etCon = (EditText)textEntryView.findViewById(R.id.edittext_edit);
    etCon.setText(strContent);
    TextView tvCon = (TextView)textEntryView.findViewById(R.id.edittext_view);
   
    m_btnConfirm = (Button)textEntryView.findViewById(R.id.plsBtnConfirm);
    m_btnCancel = (Button)textEntryView.findViewById(R.id.plsBtnCancel);
    

   
       if (0 != strTitle.length())
       tvCon.setText(strTitle);
   
       m_currDlg = new AlertDialog.Builder(m_activity).create();
       m_currDlg.setView(textEntryView);
       m_currDlg.show();

底部有条黑线

 

如果使用

         m_currDlg = new AlertDialog.Builder(m_activity).create();
       m_currDlg.setView(textEntryView,0,0,0,0);
       m_currDlg.show();

则可以得到想要的自定义的dialog

                

此时就可以控制Dialog在按了OK或者cancel的显示还是消失了

   LayoutInflater factory = LayoutInflater.from(m_activity);
    final View textEntryView = factory.inflate(R.layout.dialog_edit_text, null);

    EditText etCon = (EditText)textEntryView.findViewById(R.id.edittext_edit);
    etCon.setText(strContent);
    TextView tvCon = (TextView)textEntryView.findViewById(R.id.edittext_view);
   
    m_btnConfirm = (Button)textEntryView.findViewById(R.id.plsBtnConfirm);
    m_btnCancel = (Button)textEntryView.findViewById(R.id.plsBtnCancel);
    

   
       if (0 != strTitle.length())
       tvCon.setText(strTitle);
   
       m_currDlg = new AlertDialog.Builder(m_activity).create();
       m_currDlg.setView(textEntryView);
       m_currDlg.show();
   
    View.OnClickListener clickListener = new View.OnClickListener(){
    @Override
    public void onClick(View v) {
     long id = v.getId();
     if(id == R.id.plsBtnConfirm){
                EditText etPl = (EditText)textEntryView.findViewById(R.id.edittext_edit);
               String str = etPl.getText().toString().trim();
                  boolean bValid = UtilFun.isInputTextValid(str);
               if (!bValid)
               {
                  showWarningDlg("",m_activity.getString(R.string.str_invalid_playlist));
               }
               else
               {
                  boolean bDismiss = isPlaylistNameValid(str,NEWPLS_INPUT);
                  if(bDismiss == true) m_currDlg.cancel();
               }
     }else if(id ==R.id.plsBtnCancel){
      m_currDlg.cancel();
     }
    }
    };
   
    m_btnConfirm.setOnClickListener(clickListener);
    m_btnCancel.setOnClickListener(clickListener);
