将视频视图切换到全屏模式android

Question

我想在用户按下全屏按钮时以全屏模式显示视频视图我在互联网上搜索过，但我找到的所有解决方案都不能解决问题

这是我当前不起作用的代码：

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="#818181" >
<RelativeLayout
android:id="@+id/video_details_header"
android:layout_width="fill_parent"
android:layout_height="50dp"
android:layout_alignParentTop="true"
android:background="#000000" >
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_centerVertical="true"
android:layout_marginLeft="12dp"
android:clickable="true"
android:onClick="returnback"
android:text="Back"
android:textColor="#ffffff" />
<TextView
android:id="@+id/video_details_text_header_center"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
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>

其中包含视频视图

你知道吗

Answer 1

设置布局参数后尝试requestLayout()调用

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

Answer 2

也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，但对我来说，你似乎根本不需要设置边距您可以通过视图的宽度和重力进行操作。

Answer 3

您可能已经忘记了这行代码，因为它适合全屏显示。

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