Question

当用户按下全屏按钮时，我想以全屏模式显示视频我在互联网上搜索过，但我找到的所有解决方案都没有解决问题

这是我当前的代码，它也不起作用：

        public void setAnchorView(final View view) {
        super.setAnchorView(view);

        Button fullScreen = new Button(VideoDetails.this);
        fullScreen.setText("FullScreen");
        Log.e("media controller","Set anchorView");
        LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
        params.setMargins(view.getWidth(), 0, 5, 20);
        params.gravity =  Gravity.RIGHT;
        addView(fullScreen, params);

        fullScreen.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                 DisplayMetrics metrics = new DisplayMetrics(); getWindowManager().getDefaultDisplay().getMetrics(metrics);
                 android.widget.FrameLayout.LayoutParams params = (android.widget.FrameLayout.LayoutParams) videoview.getLayoutParams();

                 params.leftMargin = 0;
                 videoview.setLayoutParams(params);



            }
        });
            }

这是xml布局

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"

    android:background="#000000" >

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"

        android:layout_marginLeft="12dp"
        android:clickable="true"
        android:onClick="returnback"
        android:text="Back"
        android:textColor="#ffffff" />

    <TextView

        android:layout_centerInParent="true"
        android:textColor="#ffffff" />
</RelativeLayout>

<ScrollView
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:layout_below="@+id/video_details_header"
    android:layout_centerInParent="true" >

    <RelativeLayout
        android:id="@+id/layout_page"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:orientation="vertical" >

        <FrameLayout
            android:id="@+id/video_details_video"
            android:layout_width="fill_parent"
            android:layout_height="200dp"
            android:layout_alignParentTop="true"
            android:layout_centerHorizontal="true" >

            <ImageView
                android:id="@+id/video_details_thumbnail"
                android:layout_width="fill_parent"
                android:layout_height="fill_parent"
                android:clickable="true"
                android:onClick="showvideo"
                android:padding="11dp"
                android:visibility="visible" />

            <VideoView
                android:id="@+id/video_details_videoView"
                android:layout_width="fill_parent"
                android:layout_height="fill_parent"
                android:layout_gravity="center"
                android:padding="11dp"
                android:visibility="gone" />
        </FrameLayout>

包含videoview

你知道吗

Answer 1

设置布局参数后尝试requestLayout()

             ...
             params.leftMargin = 0;
             videoview.setLayoutParams(params);
             videoview.requestLayout();

Answer 2

尝试更改视图的宽度：

    WindowManager wm = (WindowManager)videoview.getContext().getSystemService(Context.WINDOW_SERVICE);
    Display display = wm.getDefaultDisplay();
    int displayWidth = display.getWidth();

    params.leftMargin = 0;
    params.width = displayWidth;
    videoview.setLayoutParams(params);
    videoview.requestLayout();

不确定因为不能全部编码，但对我而言似乎根本不需要设置边距你可能只是操纵视图的宽度和重力。

Answer 3

您可能已经忘记了这行代码，以使其适合全屏。

getWindow（）。setFlags（WindowManager.LayoutParams.FLAG_FULLSCREEN，WindowManager.LayoutParams.FLAG_FULLSCREEN）;

Answer 4

DisplayMetrics metrics = new DisplayMetrics(); getWindowManager().getDefaultDisplay().getMetrics(metrics);
             android.widget.LinearLayout.LayoutParams params = (android.widget.LinearLayout.LayoutParams) videoView.getLayoutParams();
             params.width =  metrics.widthPixels;
             params.height = metrics.heightPixels;
             params.leftMargin = 0;
             videoView.setLayoutParams(params);
