Answer 1

you can use bottom Sheets. I put some infromation about it.

With Android Support Library 23.2, Google announced support for Bottom Sheets. According to Material Design, Bottom Sheets are elements displayed only as a result of a user-initiated action, used to reveal more content.

There are two major types of bottom sheets:

Modal bottom sheets are alternatives to menus or simple dialogs. They can also present deep-linked content from other apps. They are primarily for mobile.

Persistent bottom sheets present in-app content

There is simple example

Making a BottomSheet on Android is quite easy, you just have to use a CoordinatorLayout as main element of your layout and attach a BottomSheet behavior to a view.

1 step - activity_main.xml

2 step - add bottom_sheet.xml

3 step - make your MainActivity like this:

public class MainActivity extends AppCompatActivity {

@BindView(R.id.btnButtonSheet)
Button btnBottomSheet;

@BindView(R.id.bottom_sheet)
LinearLayout layoutBottomSheet;

BottomSheetBehavior sheetBehavior;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    ButterKnife.bind(this);

    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
    setSupportActionBar(toolbar);

    sheetBehavior = BottomSheetBehavior.from(layoutBottomSheet);


    sheetBehavior.setBottomSheetCallback(new BottomSheetBehavior.BottomSheetCallback() {
        @Override
        public void onStateChanged(@NonNull View bottomSheet, int newState) {
            switch (newState) {
                case BottomSheetBehavior.STATE_HIDDEN:
                    break;
                case BottomSheetBehavior.STATE_EXPANDED: {
                    btnBottomSheet.setText("Close");
                }
                break;
                case BottomSheetBehavior.STATE_COLLAPSED: {
                    btnBottomSheet.setText("Expand");
                }
                break;
                case BottomSheetBehavior.STATE_DRAGGING:
                    break;
                case BottomSheetBehavior.STATE_SETTLING:
                    break;
            }
        }

        @Override
        public void onSlide(@NonNull View bottomSheet, float slideOffset) {

        }
    });
}

@OnClick(R.id.btnButtonSheet)
public void toggleBottomSheet() {
    if (sheetBehavior.getState() != BottomSheetBehavior.STATE_EXPANDED) {
        sheetBehavior.setState(BottomSheetBehavior.STATE_EXPANDED);
        btnBottomSheet.setText("Close Bottom sheet");
    } else {
        sheetBehavior.setState(BottomSheetBehavior.STATE_COLLAPSED);
        btnBottomSheet.setText("Expand Bottom sheet");
    }
}
}
