当我在 ICS 设备上以横向模式显示对话框时，对话框显示的宽度与纵向模式下的宽度相同。
但是在运行 Gingerbread 的设备上，当对话框处于横向模式时，它会显示整个屏幕的宽度，但并不是所有内容都很紧凑
他们是否更改了对话框在 ICS 中的显示方式，它不会像第二张图片那样在屏幕上显示？我怎样才能让它像第二张图片一样显示，而不是像第一张那样看起来紧凑？
此应用程序的目标 api 也是 2.2，所以我不能使用任何 ICS api 或任何东西
编辑
这就是我调用对话框的方式
incDialog = new MessageDialog(this, R.style.FullHeightDialog);
incDialog.PopUpMessage(this, oMessage);
对话框位于扩展对话框的单独类中
这是实际显示对话的PopUpMessage方法
public void PopUpMessage(final Context context, clsMessageRecord oMessage) {
MainActivity.lastMessageClicked = oMessage;
moCallingContext = context;
moMessage = oMessage;
MainActivity.miShownDialogType = DialogID;
MainActivity.setShownMessage(moMessage);
MainActivity.mbIntentWasShown = true;
Log.i(className + "::PopUpMessage", "New Message Dialog Show....");
if (oMessage != null) {
if (oMessage.getIsStation() == true) {
// Incident Message Dialog
this.setContentView(R.layout.message_st);
clsStatusRecord oStation = ControlService.DB.StatusList.GetMessageByECM2ID(oMessage.ECM2ID);
if (oStation != null) {
if (oStation.AllowMapping()) {
ImageButton cmdMapping = (ImageButton) this.findViewById(R.id.cmdMapping);
cmdMapping.setVisibility(ImageButton.VISIBLE);
cmdMapping.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
MainActivity.loaded = false;
HandleMapping();
}
});
} else {

最佳答案
是的，API 11 是针对平板电脑和大屏幕的，而 AlertDialog 的设计不会覆盖 Holo 主题中的整个屏幕。它的默认大小取决于屏幕大小(表示为屏幕宽度的百分比宽度)。
不清楚什么是 MessageDialog 的基类。 假设它继承了AlertDialog，那么一个主题设置对话框的大小。
假设您在 list 中有 android:targetSdkVersion>=11，应用程序使用 Theme.Holo.Dialog.Alert 对话框主题，它设置 android:windowMinWidthMajor 和 android:windowMinWidthMinor 来指定对话框的宽度。
您可以通过设置 android:targetSdkVersion=10 来解决此问题，或者通过为对话框制作和使用自己的主题，其中父主题为 Theme.Holo.Dialog.Alert 并且您将覆盖提到的宽度项目。
