Nach dem Drücken von FAB BottomSheet erscheint auf dem Bildschirm, aber die Position ist falsch (siehe Bild 1), ich möchte es wie auf dem Bild machen 2. Wie es zu beheben ?Falsche Position der BottomSheet im Bildschirm
Meine Aktivität:
public class FirstscreenActivity extends AppCompatActivity implements RecyclerItemClickListener.OnItemClickListener,
ItemAdapter.ItemListener {
private BottomSheetDialog mBottomSheetDialog;
BottomSheetBehavior behavior;
private ItemAdapter mAdapterItem;
private FloatingActionButton floatButton;
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.front);
floatButton = (FloatingActionButton) findViewById(R.id.float_button);
floatButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
showBottomSheetDialog();
mBottomSheetDialog.getWindow().setLayout(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT);
mBottomSheetDialog.getWindow().setGravity(Gravity.BOTTOM);
}
});
View bottomSheet = findViewById(R.id.bottom_sheet);
behavior = BottomSheetBehavior.from(bottomSheet);
behavior.setBottomSheetCallback(new BottomSheetBehavior.BottomSheetCallback() {
@Override
public void onStateChanged(@NonNull View bottomSheet, int newState) {
// React to state change
}
@Override
public void onSlide(@NonNull View bottomSheet, float slideOffset) {
// React to dragging events
}
});
mAdapterItem = new ItemAdapter(createItems(), this);
}
@Override
protected void onResume() {
super.onResume();
RecyclerViewAdapter adapter = (RecyclerViewAdapter) mList.getAdapter();
adapter.notifyDataSetChanged();
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.menu, menu);
return super.onPrepareOptionsMenu(menu);
}
private void showBottomSheetDialog() {
if (behavior.getState() == BottomSheetBehavior.STATE_EXPANDED) {
behavior.setState(BottomSheetBehavior.STATE_COLLAPSED);
}
mBottomSheetDialog = new BottomSheetDialog(this);
View view = getLayoutInflater().inflate(R.layout.sheet, null);
RecyclerView recyclerView = (RecyclerView) view.findViewById(R.id.recyclerView);
recyclerView.setHasFixedSize(true);
recyclerView.setLayoutManager(new LinearLayoutManager(this));
recyclerView.setAdapter(new ItemAdapter(createItems(), new ItemAdapter.ItemListener() {
@Override
public void onItemClick(Item item) {
if (mBottomSheetDialog != null) {
mBottomSheetDialog.dismiss();
}
}
}));
mBottomSheetDialog.setContentView(view);
mBottomSheetDialog.show();
mBottomSheetDialog.setOnDismissListener(new DialogInterface.OnDismissListener() {
@Override
public void onDismiss(DialogInterface dialog) {
mBottomSheetDialog = null;
}
});
}
@Override
protected void onDestroy() {
super.onDestroy();
mAdapterItem.setListener(null);
}
public List<Item> createItems() {
ArrayList<Item> items = new ArrayList<>();
items.add(new Item("Add new record"));
items.add(new Item(R.drawable.camera, "from new shoots"));
items.add(new Item(R.drawable.folder_multiple_image, "from ready images"));
return items;
}
@Override
public void onItemClick(Item item) {
behavior.setState(BottomSheetBehavior.STATE_COLLAPSED);
}
}
-Code des Adapters des RecyclerView, die in der BottomSheet ist:
public class ItemAdapter extends RecyclerView.Adapter<RecyclerView.ViewHolder> {
private List<Item> mItems;
private ItemListener mListener;
public ItemAdapter(List<Item> items, ItemListener listener) {
mItems = items;
mListener = listener;
}
public void setListener(ItemListener listener) {
mListener = listener;
}
@Override
public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
switch (viewType) {
case 0:
return new ViewHolderModified(LayoutInflater.from(parent.getContext())
.inflate(R.layout.bottom_title, parent, false));
default:
return new ViewHolder(LayoutInflater.from(parent.getContext())
.inflate(R.layout.item, parent, false));
}
}
@Override
public void onBindViewHolder(RecyclerView.ViewHolder holder, int position) {
if (position == 0){
ViewHolderModified holderModified = (ViewHolderModified)holder;
holderModified.setData(mItems.get(position));
}
else {
ViewHolder viewHolder = (ViewHolder)holder;
viewHolder.setData(mItems.get(position));
}
}
@Override
public int getItemCount() {
return mItems.size();
}
public class ViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {
public ImageView imageView;
public TextView textView;
public Item item;
public ViewHolder(View itemView) {
super(itemView);
itemView.setOnClickListener(this);
imageView = (ImageView) itemView.findViewById(R.id.imageView);
textView = (TextView) itemView.findViewById(R.id.textView);
}
public void setData(Item item) {
this.item = item;
imageView.setImageResource(item.getDrawableResource());
textView.setText(item.getTitle());
}
@Override
public void onClick(View v) {
if (mListener != null) {
mListener.onItemClick(item);
}
}
}
public class ViewHolderModified extends RecyclerView.ViewHolder implements View.OnClickListener {
public TextView textView;
public Item item;
public ViewHolderModified(View itemView) {
super(itemView);
itemView.setOnClickListener(this);
textView = (TextView) itemView.findViewById(R.id.titleView);
}
public void setData(Item item) {
this.item = item;
textView.setText(item.getTitle());
}
@Override
public void onClick(View v) {
if (mListener != null) {
mListener.onItemClick(item);
}
}
}
public interface ItemListener {
void onItemClick(Item item);
}
@Override
public int getItemViewType(int position) {
return position;
}
}
