Question

当我在横向模式下在ICS设备上显示对话框时，对话框显示的宽度与在纵向模式下的宽度相同。

enter image description here

但是当对话框处于横向模式时，在运行姜饼的设备上，它会在屏幕上显示宽度并没有紧凑的一切

enter image description here

他们是否改变了ICS中对话框的显示方式，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出来，所以它看起来不像第一张图片那么紧凑？

这个应用程序的目标api也是2.2所以我不能使用任何ICS api或任何东西

修改

这就是我调用对话框的方式

incDialog = new MessageDialog(this, R.style.FullHeightDialog);
incDialog.PopUpMessage(this, oMessage);

对话框位于一个扩展对话框的单独类中

这是实际显示daialog

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);

Answer 1

是的，API 11针对的是平板电脑和大屏幕，而AlertDialog的设计并不涵盖Holo主题的整个屏幕。其默认大小取决于屏幕大小（表示为屏幕宽度的百分比宽度）。

目前尚不清楚MessageDialog的基类是什么。假设它继承了AlertDialog，那么主题设置对话框的大小。

假设你在清单中有android：targetSdkVersion＆gt; = 11，app会使用Theme.Holo.Dialog.Alert主题进行对话，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来修复此问题，或者通过制作和使用自己的主题进行对话，其中父主题将是Theme.Holo.Dialog.Alert，并且您将覆盖提到的宽度项目。

Answer 2

如果您要使用自定义对话框，最好将它们放在XML文件中。

在我的自定义对话框中，我使用了一个带有android：layout_width =“wrap_content”的RelativeLayout，它们适应屏幕方向及其内容恰到好处。

dialog_layout.xml应如下所示：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:background="@drawable/dialog_background"
    android:padding="@dimen/dialog_padding" >

    <TextView
    android:id="@+id/text_view"
    style="@style/WhiteTextLabel"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content" 
    android:layout_alignParentTop="true"
    android:text="@string/dialog_text" />

    <LinearLayout
        android:id="@+id/buttons"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_below="@id/text_view"
        android:orientation="horizontal" >

        <Button
            android:id="@+id/button_cancel" 
            style="@style/RedCancelButton"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            android:text="@string/button_cancel" />

        <Button
            android:id="@+id/button_done"
            style="@style/GreenDoneButton"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            android:text="@string/button_done" />
    </LinearLayout>
</RelativeLayout>

从Java代码中膨胀它：

final Dialog aDialog = new Dialog(this);
aDialog.requestWindowFeature(Window.FEATURE_LEFT_ICON);
aDialog.setTitle(getString(R.string.dialog_title));
aDialog.setContentView(R.layout.dialog_layout);
aDialog.setFeatureDrawableResource(Window.FEATURE_LEFT_ICON, R.drawable.ic_dialog_icon);
aDialog.setCancelable(true);

final Button buttonDone = (Button) aDialog.findViewById(R.id.button_done);
final Button buttonCancel = (Button) aDialog.findViewById(R.id.button_cancel);

    buttonDone.setOnClickListener(new OnClickListener() {
    public void onClick(View v) {
        // TODO Do something...
        aDialog.cancel();
    }
    });             
    buttonCancel.setOnClickListener(new OnClickListener() {                 
    public void onClick(View v) {
        // Do nothing
        aDialog.cancel();
    }
    });         
aDialog.show();

我的minSdkVersion是8，targetSdkVersion是15.我没有在对话框中应用任何主题，但我正在自定义背景（形状可绘制），按钮（带样式）等。对话框的外观和行为相同从Froyo到ICS的任何设备。

我的/ layout /文件夹中只有1个xml ...但您可能想根据/ layout-land /文件夹中的方向创建另一个具有相同名称的xml并进行一些调整。

虽然引用Using Dialog Fragments，新的API有Dialog Fragments，你可能也想看看它们。

我希望这会有所帮助。祝你好运！
