如何实现警报对话框？

Question

我有一个按钮，如果点击该按钮会打开一个包含呼叫记录列表的警告对话框。但是这样做只显示对话框标题。这是我的代码：

 protected void showCustomDialog() {
            // TODO Auto-generated method stub

            // this method returns the cursor with all call logs.. i've checked the cursor                                 and it is returning.
            Cursor curLog = CallLogHelper.getAllCallLogs(getContentResolver());

            // it fills the conNames arraylist with its values.
            setCallLogs(curLog);

            ListView listitems=new ListView(this);
            MyAdapter adapter = new MyAdapter( this , R.layout.dialog_list,conNames);

            //dialog_list is layout of each item of the list.

            alertDialogStores = new AlertDialog.Builder(MainActivity.this)
            .setView(listitems)
            .setTitle("Stores")
            .show();
}

Answer 1

您需要使用以下代码显示您的日志：

使用下面的代码从arraylist形成字符串，如下所示：

String msg="";
for(int i=0;i<conNames.size();i++)
{msg=msg+" "+conNames;}

  alertDialogStores = new AlertDialog.Builder(MainActivity.this)
            .setView(listitems)
            .setTitle("Stores")
            .show();
            .setMessage("my logs"+msg);

Answer 2

写

listitems.setAdapter(adapter);

之后

ListView listitems=new ListView(this);
MyAdapter adapter = new MyAdapter( this , R.layout.dialog_list,conNames);
