如何让布局从底部向上滑动？

单击按钮从底部获取 LinearLayout。但是有一个问题。

1. 布局完成后，VideoView 不能一键工作。在第二次点击时起作用。

2. 如果我触摸顶部布局以外的任何地方，我想让布局消失。（当然，点击后的 VideoView 应该不会工作。）

3. 如果我单击 EditText，我想将 EditText 和按钮放在软键盘上。（它现在被软键盘遮挡了。）

这是我的代码。

代码

public class PlayActivity extends AppCompatActivity {

public void onCreate(){

  ...

videoView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                if(videoView.isPlaying()){      
                    videoView.pause();
                    playimg.setVisibility(View.VISIBLE);
                }else{                          
                    videoView.start();
                    playimg.setVisibility(View.INVISIBLE);
                }
            }
        });

...

comm.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {

                if(!CommShown()){

                    Animation bottomUp = AnimationUtils.loadAnimation(PlayActivity.this,R.anim.bottom_up);
                    comm_layout.startAnimation(bottomUp);
                    comm_layout.setVisibility(View.VISIBLE);
                    viewGroup.setEnabled(false);
                    //enableDisableViewGroup(viewGroup, false);
                }


            }
        });


        comm_close.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                if(CommShown()){
                        Animation bottomUp = AnimationUtils.loadAnimation(PlayActivity.this,R.anim.bottom_down);
                        comm_layout.startAnimation(bottomUp);
                        comm_layout.setVisibility(View.INVISIBLE);
                    enableDisableViewGroup(viewGroup, true);
                }
            }
        });

} // onCreate


    //comm Visible or Invisivle check

    private boolean CommShown() {
        return comm_layout.getVisibility() == View.VISIBLE;
    }

    //Comm Open and disable rear view
    public static void enableDisableViewGroup(ViewGroup viewGroup, boolean enabled) {
        int childCount = viewGroup.getChildCount();
        for (int i = 0; i < childCount; i++) {


            View view = viewGroup.getChildAt(i);
            view.setEnabled(enabled);

            if (view instanceof ViewGroup) {
                enableDisableViewGroup((ViewGroup) view, enabled);
            }
        }
   }
}
