自定义对话框中的ImageView - fill_parent不起作用，对话框很小 [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：我必须在一个对话框中放置一些照片（一些小的分辨率，一些大的分辨率）并显示全屏。

我尝试过：

 对话框对话框=新对话框（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（）; 
  

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> 
  

当我在任何地方填写fill_parent时，对话框不应该全屏吗？

解决方案

尝试：

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

希望有帮助。

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

I tried this:

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();

And my layout is:

<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>

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

解决方案

Try that:

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

Hope it helps.
