如何使布局从底部向上滑动？

Question

Click the button to get LinearLayout from the bottom. But there's a problem.

1. After the layout is finished, the VideoView doesn't work with one click. Works on the second click.

2. I want to make the layout disappear if I touch anywhere other than the layout on top. (Of course, the VideoView at the rear should not work when clicked.)

3. If I click EditText, I want to place the EditText and the buttons on the soft keyboard. (It is now obscured by the softkeyboard.)

this is my code.

Java code

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);
            }
        }
   }
}

I am sorry that I am not good at English. And thank you for your help.

Answer 1

For sliding a layout up from the bottom of the screen, you can use BottomSheet provided by Android.

And for keyboard hiding edit text in the bottom layout, you can check out this post here

I hope it helps!
