Button in Fragment is unclickable in android studio

Button in Fragment is unclickable in android studio - android

I am trying to have a button go from a fragment layout to an xml file. However when running the app, I can not click on the button. I've checked if I have to correct id. This is the case. Does someone know the answer why it won't trigger my onClickListener()? I feel like it is something small that I'm am missing, but I don't know exactly what. Thanks !

I have check your code on Android Studio the code is perfect but one mistake is there as you have set Viewpager above parent RelativeLayout as match parent hence you are not getting button to click but if you refactor Viewpager below the button the you are able to get click.
Here is what you can do. I have AndroidX installed so codeis in that

why you don't use butterknife
add to gradle ->
implementation 'com.jakewharton:butterknife:9.0.0-rc2'
annotationProcessor 'com.jakewharton:butterknife-compiler:9.0.0-rc2'
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
RootView = inflater.inflate(R.layout.fragment_account, container, false);
ButterKnife.bind(this, RootView );
...
return RootView;
}
#OnClick(R.id.open_settings)
public void btn(){
Intent i = new Intent(getContext(), PreferenceFragmentAccount.class);
startActivity(i);
}
okey so you can change source like this :
Button openSettingsButton;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
RootView = inflater.inflate(R.layout.fragment_account, container, false);
Log.i(TAG, "onCreateView()");
// Create the adapter that will return a fragment for each of the three
// primary sections of the activity.
mSectionsPagerAdapter = new SectionsPagerAdapter(myContext.getSupportFragmentManager());
// Set up the ViewPager with the sections adapter.
mViewPager = (ViewPager) RootView.findViewById(R.id.container);
mViewPager.setAdapter(mSectionsPagerAdapter);
//BUTTON
openSettingsButton = RootView.findViewById(R.id.open_settings);
return RootView;
}
#Override
public void onViewCreated(View view, Bundle savedInstanceState) {
openSettingsButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent i = new Intent(getContext(), PreferenceFragmentAccount.class);
startActivity(i);
}
});
}

RecyclerView that using GridLayoutManager with background makes different heights visible

I've made an adapter with a layout like the one I share below. it went well but, the appearance of each item became untidy.
Here is my code :
public class TableRecyclerAdapter extends RecyclerView.Adapter<TableRecyclerAdapter.ViewHolder> {
private ArrayList<TableModel> data;
private Context context;
private Fragment fragment;
private Dialog dialog;
public TableRecyclerAdapter(Context context, ArrayList<TableModel> data, Fragment fragment, Dialog dialog) {
this.context = context;
this.data = data;
this.fragment = fragment;
this.dialog = dialog;
}
#Override
public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
LayoutInflater inflater = LayoutInflater.from(parent.getContext());
View v = inflater.inflate(R.layout.item_table, parent, false);
return new ViewHolder(v);
}
#Override
public void onBindViewHolder(ViewHolder holder, final int position) {
holder.tvTable.setText(data.get(position).getName());
holder.tvState.setText(data.get(position).getStateString());
holder.bg.setBackgroundColor(Color.parseColor(data.get(position).getWarna()));
holder.tvHtml.setText(Html.fromHtml(data.get(position).getShortInfoHtml()));
holder.itemView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
}
});
}
#Override
public int getItemCount() {
return data.size();
}
class ViewHolder extends RecyclerView.ViewHolder {
private ImageView paid;
private TextView tvTable, tvHtml, tvState;
private ConstraintLayout bg;
public ViewHolder(View itemView) {
super(itemView);
tvTable = itemView.findViewById(R.id.tvTable);
tvHtml = itemView.findViewById(R.id.tvHtml);
bg = itemView.findViewById(R.id.bg);
tvState = itemView.findViewById(R.id.tvState);
paid = itemView.findViewById(R.id.ivPaid);
}
}
}

It makes my recyclerview have different heights depending on the text.
I want the items to be the same height per row (maximum height in the row)
Sorry for my english. I hope someone can help me. Thank you

Andriod Studio ListView doesn't update itself

I have ListView and my own adapter. ListView item consists of TextView, icon image and image "trash can"(simply "trash"). The problem is when i click on any item it should be deleted but in fact the last item of ListView disappears. I checked ArrayList and the item I clicked on is deleted from there.
Also when i try to add new item the program just restore previous items and if all initial items are displayed and i try to add new the program crashes. Although in ArrayList items are added correctly.
Activity code

Looks like your data is not properly updated inside the Adapter's getView method.
You should try to update the item inside the Adapter when contentView is not null.
For performance reason, there is a pattern called ViewHolder used inside the adapter. Refer to Android listview using ViewHolder for more info. Just create Holder when contentView is null and set the data when it isn't. Hope it helps.
P.S. ListView is considered deprecated. Use RecyclerView instead. It has already built-in ViewHolder pattern and is more flexible

recyclerview items size not the same size in layout

I'm trying to make a nested recyclerview with multiple items and after finishing the adatper and design and going in testing I got this in the emulator
I didn't understand why items appears like that, the items not the same height and width which I make it for the design of it's layout.
here is the code for recyclerview setup
mRecyclerView.setHasFixedSize(true);
adapter = new CheckoutMainRecyAdapter(CheckOutActivity.this, allSampleData);
mRecyclerView.setLayoutManager(new LinearLayoutManager(CheckOutActivity.this));
mRecyclerView.setAdapter(adapter);
and here is the adapter code
public class CheckoutMainRecyAdapter extends RecyclerView.Adapter<RecyclerView.ViewHolder> {
private ArrayList<CheckoutMainModel> dataList;

You have to supply the recycler as the root to the inflate method, so that the inflated view gets the correct layout parameters from the parent
You have to set attachToRoot to false, because the recycler view handles the attaching.
Example:
view = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.your_layout, viewGroup, false);

change ImageView based on the clicked spinner item its not working

I have 2 two images (item1.png and item2.png) and I want to show each image in a ImageView when the items on the spinner are clicked. When the "item1" in the spinner is selected I want to show the "item1.png" image and the same for the "item2".
Im trying to do this with the code below but its no working. Do you know what is the issue?
On MainActivity:
public class MainActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Spinner spinner = (Spinner) findViewById(R.id.spinner2);
String string = String.valueOf(spinner.getSelectedItem());
final ImageView image = (ImageView)findViewById(R.id.image);
int image1 = R.drawable.item1;
int image2 = R.drawable.item2;
spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
//spinner.
#Override
public void onItemSelected(AdapterView<?> arg0, View arg1,
int arg2) {
if (arg2 == 0) {
image.setImageResource(R.drawable.item1);
} else {
image.setImageResource(R.drawable.item2);
}
}
}
}
}

Try to change OnItemSelectedListener like below:
spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
switch (position) {
case 0:
image.setImageResource(R.drawable.item1);
break;
case 1:
image.setImageResource(R.drawable.item2);
break;
default:
//Default image
//image.setImageResource(R.drawable.item2);
break;
}
}
#Override
public void onNothingSelected(AdapterView<?> parent) {
}
});

Show fragment recyclerViews in Parent Activity

I am simply trying to show a fragments recyclerView inside it's parent activity. The data is there but nothing is showing up. Any thoughts? Here is PagerAdapter, parent and fragment classes with xmls so that all the parts are available to see. I want the RV to fit right here between the CardView and comment line. Thanks for any help!
PagerAdapter

final int PAGE_COUNT = 2;

this.context = context;
}
#Override
public int getCount() {
return PAGE_COUNT;
}
#Override
public Fragment getItem(int position) {
return CommentFragment.newInstance(position + 1);
}
#Override

// Generate title based on item position
return tabTitles[position];
}
