推荐答案

您可以使用AlertDialog来做到这一点。看看这里http://developer.android.com/guide/topics/ui/dialogs.html.并滚动到创建自定义对话框。示例如下：

You can use AlertDialog to do this. Look here http://developer.android.com/guide/topics/ui/dialogs.html. And scroll to Creating a Custom Dialog. Example is:

AlertDialog.Builder builder;
AlertDialog alertDialog;

Context mContext = getApplicationContext();
LayoutInflater inflater = (LayoutInflater) mContext.getSystemService(LAYOUT_INFLATER_SERVICE);
View layout = inflater.inflate(R.layout.custom_dialog,
                               (ViewGroup) findViewById(R.id.layout_root));

TextView text = (TextView) layout.findViewById(R.id.text);
text.setText("Hello, this is a custom dialog!");
ImageView image = (ImageView) layout.findViewById(R.id.image);
image.setImageResource(R.drawable.android);

builder = new AlertDialog.Builder(mContext);
builder.setView(layout);
alertDialog = builder.create();
