我正在使用以下代码从自定义适配器中打开一个片段对话框:
HomeActivity activity = (HomeActivity) (context);
FragmentManager fm = activity.getSupportFragmentManager();
editor.putString("post_media", remainder);
editor.apply();
PostVideoFragment alertDialog = new PostVideoFragment();
alertDialog.show(fm, "fragment_alert");
这是片段对话框的布局:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@android:color/black">
<VideoView
android:id="@+id/video"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</RelativeLayout>
这是fragmentdialog的代码:
public class PostVideoFragment extends DialogFragment {
VideoView post_video;
public static String MISDATOS= "MisDatos";
SharedPreferences prefs;
SharedPreferences.Editor editor;
String post_media;
public static PostVideoFragment newInstance() {
PostVideoFragment fragment = new PostVideoFragment();
return fragment;
}
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.fragment_post_video, container, false);
prefs = getActivity().getSharedPreferences(MISDATOS, Context.MODE_PRIVATE);
editor = prefs.edit();
post_media = prefs.getString("post_media", "no");
String url = "https://f..postsmedia/";
final VideoView videoView;
videoView = (VideoView)v.findViewById(R.id.video);
videoView.setVideoPath(url+post_media);
videoView.start();
return v;
}
}
功能是正确的,可以播放视频,但是当屏幕处于横向模式时,我需要全屏播放,现在只能以很小的模式显示。
以下是输出:

关于对话框的大小,我也有类似的问题,为我解决的是用LayoutParams
定义对话框的大小,如下所示:
Window window = yourDialog.getWindow();
if (window != null) {
WindowManager.LayoutParams lp = new WindowManager.LayoutParams();
lp.copyFrom(window.getAttributes());
//This makes the dialog take up the full width
lp.width = WindowManager.LayoutParams.MATCH_PARENT;
lp.height = WindowManager.LayoutParams.MATCH_PARENT;
window.setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
window.setAttributes(lp);
}
但是为什么不能只将XML对话框设置为match_parent
并结束呢?
似乎默认对话框LayoutParams(wrap_content,wrap_content)覆盖了XML(match_parent,match_parent)中的LayoutParams。
这就是为什么您可以使用固定大小(150dp,150dp)并看到对话框大小发生变化的原因,但是对话框将不会响应,因此这不是一个明智的解决方案。

在cell
的{{1}}中,您可以将高度和宽度设置为reloaded
,如下所示:
<button mat-button disabled="!isAccessible(item.name)">Action1</button>
