相似代码 可以铺满全屏

mediaPlayer.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
    @Override
    public void onPrepared(final MediaPlayer mp) {
        // 点击过快可能导致mp未解析完成 故延时
        handler.postDelayed(()-> {
            if (mp == null) {
                JXLog.e("mediaListener onPrepared mp is null ");
                return;
            }
            jxSurface.setPause(false);
            int vWidth = mp.getVideoWidth();
            int vHeight = mp.getVideoHeight();
            // 该LinearLayout的父容器 android:orientation="vertical" 必须
            LinearLayout linearLayout = (LinearLayout) findViewById(R.id.layoutPlay);
            int lw = linearLayout.getWidth();
            int lh = linearLayout.getHeight();
            float wRatio = (float) vWidth / (float) lw;
            float hRatio = (float) vHeight / (float) lh;
            // 选择大的一个进行缩放
            float ratio = Math.max(wRatio, hRatio);
            vWidth = (int) Math.ceil((float) vWidth / ratio);
            vHeight = (int) Math.ceil((float) vHeight / ratio);
            // 设置surfaceView的布局参数
            LinearLayout.LayoutParams lp= new LinearLayout.LayoutParams(vWidth, vHeight);
            lp.gravity = Gravity.CENTER;
            jxSurface.setLayoutParams(lp);
            jxSurface.setPlaying(true);
            mediaPlayer.start();
        },100);
    }
});

并没有铺满 代码呢 布局呢 不能只给几张图让大家伙猜吧
