ImageView的在自定义对话框 - FILL_PARENT不工作，我的对话框中小 [英] ImageView in a Custom Dialog - fill_parent does not work and my dialog is small

问题描述

我有一个简单的要求：我必须把一些照片（一些小的分辨率，一些大的分辨率）在一个对话框并显示全屏

I have a simple request: I have to put some pictures (some small resolution, some big resolution) in a dialog and display them fullscreen.

我试过这样：

Dialog dialog = new Dialog(getActivity());
dialog.setContentView(R.layout.custom_dialog);
int picId = Integer.valueOf(webcamCursor.getString(webcamCursor
        .getColumnIndex("_id")));
dialog.setTitle(webcamCursor.getString(webcamCursor
        .getColumnIndex("City")));
image = (ImageView) dialog.findViewById(R.id.image);
image.setImageResource(R.drawable.icon);            
new DownloadPicTask().execute(Snippets.getUrlFromCat(picId, cat));
dialog.show();

和我的布局是：

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
              android:id="@+id/layout_root"
              android:orientation="vertical"
              android:layout_width="fill_parent"
              android:layout_height="fill_parent"
              android:layout_gravity="center"
              >
    <ImageView android:id="@+id/image"
               android:layout_width="fill_parent"
               android:layout_height="fill_parent"
               android:padding="10dip"
               />
</LinearLayout>

由于我写FILL_PARENT无处不在，不应该对话框拿全屏？

As I wrote fill_parent everywhere, shouldn't the dialog take the full screen?

推荐答案

试一下：

dialog.getWindow().getAttributes().width = LayoutParams.FILL_PARENT;

希望它帮助。
