我正在使用自定义对话框在屏幕上显示某些内容

绿色部分是对话框 - 它应该是整个屏幕宽度

为什么它不占用整个屏幕宽度?

这是我的对话框代码

        participantsPanelDialog = new Dialog(getSherlockActivity(), R.style.ParticipantsDialog);
        // Making sure there's no title.
        participantsPanelDialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
        // Making dialog content transparent.
        participantsPanelDialog.getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
        // Removing window dim normally visible when dialog are shown.

        participantsPanelDialog.getWindow().addFlags(WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL);
        participantsPanelDialog.getWindow().clearFlags(WindowManager.LayoutParams.FLAG_DIM_BEHIND);
        // Setting position of content, relative to window.
        WindowManager.LayoutParams params = participantsPanelDialog.getWindow().getAttributes();
        params.gravity = Gravity.TOP | Gravity.LEFT;
        params.x = 0;
        params.y = 0;
//      params.width = ((Activity) getActivity()).getWindow().getAttributes().width;
//      Toast.makeText(getActivity(), "width: " +params.width, Toast.LENGTH_LONG).show();
        participantsPanelDialog.getWindow().setLayout(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT);

这是我的布局

</RelativeLayout>

这是结果:

我的问题是,当我创建对话框时,我正在扩展Android.Theme.Dialog样式

这使它缩小

以这种风格R.style.ParticipantsDialog- 我删除了父主题,它像我想要的那样增长到全尺寸

通过这样做,对话框可以占据​​你想要的所有宽度:

DisplayMetrics metrics = getResources().getDisplayMetrics();
int width = metrics.widthPixels;
...
participantsPanelDialog.getWindow().setLayout(width, LayoutParams.WRAP_CONTENT);

顺便说一句,对话框是一个“窗口”,我认为它的设计目的不是为了占据屏幕上的所有可用空间。

试试下面的代码

    int DisplayWidth, DisplayHeight;
    Dialog dialog;

   Display display =((WindowManager)Your_context.getSystemService(Context.WINDOW_SERVICE)).getDefaultDisplay();

            DisplayWidth = display.getWidth();
            DisplayHeight = display.getHeight();

            dialog = new Dialog(activity_context);

              // Set your dialog width and height dynamically as per your screen.

            Window window = dialog.getWindow();
            window.setLayout(DisplayWidth , DisplayHeight);
            window.setGravity(Gravity.CENTER);

            dialog.show();

<style name="ThemeDialog" parent="@android:style/Theme.Dialog">
    <item name="android:windowBackground">@null</item>
    <item name="android:windowFrame">@null</item>
    <item name="android:windowNoTitle">true</item>
</style>

将上述添加到您的 style.xml,并将对话框样式设置为 ThemeDialog。
