Android全屏播放视频~包括刘海屏、隐藏时间状态栏

需求是全屏播放视频，刘海屏上面也要播放。

下面是我实现的方式：

首先创建 CustomVideoView 工具类：

import android.annotation.TargetApi;
import android.content.Context;
import android.util.AttributeSet;
import android.widget.VideoView;

/**

public class CustomVideoView extends VideoView {
    public CustomVideoView(Context context) {
        super(context);
    }

    public CustomVideoView(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public CustomVideoView(Context context, AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
    }

    @TargetApi(21)
    public CustomVideoView(Context context, AttributeSet attrs, int defStyleAttr, int defStyleRes) {
        super(context, attrs, defStyleAttr, defStyleRes);
    }

    @Override
    protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
        //int widthSpecMode = MeasureSpec.getMode(widthMeasureSpec);
        int widthSpecSize = MeasureSpec.getSize(widthMeasureSpec);
        //int heightSpecMode = MeasureSpec.getMode(heightMeasureSpec);
        int heightSpecSize = MeasureSpec.getSize(heightMeasureSpec);

        setMeasuredDimension(widthSpecSize, heightSpecSize);
    }
}

 

然后在xml文件中应用：

 

最后在 activity 中使用：

import android.content.res.Resources;
import android.graphics.Color;
import android.os.Build;
import android.os.Bundle;
import android.support.annotation.RequiresApi;
import android.support.v4.app.FragmentActivity;
import android.util.DisplayMetrics;
import android.view.View;
import android.view.ViewGroup;
import android.view.WindowManager;

import ceshi.com.myapp.R;
import ceshi.com.myapp.utils.CustomVideoView;

/**
 * Name: 吴庆森
 * Date: 2019/7/9

public class VideoActivity1 extends FragmentActivity {
    CustomVideoView videoPlay;


    @RequiresApi(api = Build.VERSION_CODES.LOLLIPOP)
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setInit();

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

        setContentView(R.layout.video_activivy1);

        videoPlay = findViewById(R.id.videoPlay);

        DisplayMetrics dm = new DisplayMetrics();
        //获取屏幕信息(单位：px)
        getWindowManager().getDefaultDisplay().getMetrics(dm);
        int screenWidth = dm.widthPixels;
        int screenHeigh = dm.heightPixels;

        int notificationBar = Resources.getSystem().getDimensionPixelSize(Resources.getSystem().getIdentifier("status_bar_height", "dimen", "android"));
        //30dp转化为px
        final float scale = getResources().getDisplayMetrics().density;
        //由30dp转化来的px
        int px = (int) (notificationBar * scale + 0.5f);

        //动态设置控件宽高
        ViewGroup.LayoutParams params = videoPlay.getLayoutParams();
        params.height = screenHeigh + (px);
        params.width = screenWidth ;
        videoPlay.setLayoutParams(params);
        videoPlay.setVideoPath("https://vdse.bdstatic.com/90bbe567a344884644b7046ba4b9906e.mp4?authorization=bce-auth-v1%2F40f207e648424f47b2e3dfbb1014b1a5%2F2017-05-11T09%3A02%3A31Z%2F-1%2F%2F1addef5f6cf2e56204e1f49e982c26e425b0fb9d9f845231bd7db8c541dcaeee");
        videoPlay.start();
    }

    @RequiresApi(api = Build.VERSION_CODES.LOLLIPOP)
    private void setInit() {
        //沉浸状态栏
        getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN | View.SYSTEM_UI_FLAG_LAYOUT_STABLE);
        getWindow().addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
        getWindow().setStatusBarColor(Color.TRANSPARENT);
        //设置页面全屏显示
        WindowManager.LayoutParams lp = getWindow().getAttributes();
        lp.layoutInDisplayCutoutMode = WindowManager.LayoutParams.LAYOUT_IN_DISPLAY_CUTOUT_MODE_SHORT_EDGES;
        //设置页面延伸到刘海区显示
        getWindow().setAttributes(lp);

    }
}

 

这样就可以全屏幕播放视频了，但是视频会有一定的拉伸。
