my java code for this layout:
public class Atherosclerosis extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.atherosclerosis);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.atherosclerosis, menu);
return true;
}
}

Use android:onClick="" and android:Clickable="true"
to make the Textview as a button

You can use OnClickListener on TextView and then use the following method on the OnClick, where textViewAbove is the TextView that is above the one you need to jump:
scrollView.post(
new Runnable() {
#Override
public void run() {
new CountDownTimer(1500, 20) {
#Override
public void onTick(long millisUntilFinished) {
scrollView.scrollTo(0, (int) (textViewAbove.getBottom()-millisUntilFinished));
}
#Override
public void onFinish() {
}
}.start();
}
}
);
Hope it helps!

You can have OnclickListener on TextView

Here is the code but still give me error till me where I am wrong?
public class Atherosclerosis extends Activity{
ScrollView scrollView;
TextView tvabove=(TextView)findViewById(R.id.pathophysiology_id);
#TargetApi(Build.VERSION_CODES.HONEYCOMB)
#SuppressLint("NewApi")
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.atherosclerosis);
ActionBar bar = getActionBar();
bar.setBackgroundDrawable(new ColorDrawable(Color.parseColor("#6B8E23")));
getActionBar().setDisplayHomeAsUpEnabled(true);
getActionBar().setHomeButtonEnabled(true);
TextView tv=(TextView)findViewById(R.id.Signandsymptompsid);
tv.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
scrollView.post(
new Runnable() {
#Override
public void run() {
new CountDownTimer(1500, 20) {
#Override
public void onTick(long millisUntilFinished) {
scrollView.scrollTo(0, (int) (tvabove.getBottom()-millisUntilFinished));
}
#Override
public void onFinish() {
}
}.start();
}
}
);
}
});
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.atherosclerosis, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Take appropriate action for each action item click
switch (item.getItemId()) {
case R.id.id_search:
Intent newActivity0 = new Intent(this,Search.class);
startActivity(newActivity0);
return true;
case R.id.id_favorit:
return true;

How to retrieve RecyclerView position

I am trying to get the position of items in my RecyclerView, mainly those that are at [0], [1], and [2] positions. The reason being is currently I am creating a leader board that will highlight the top 3 players with the highest score.
I have tried calling getAdapterPosition() but I guess I am using it incorrectly.
if(holder.getAdapterPosition() == 0)
{
Glide.with(holder.firstPlace.getContext())
.load(model.getUrl())
.into(holder.firstPlace);
}
I would greatly appreciate if someone could point me to the right direction. Thank you.
Edit 1:
My UserAdapter
public class UserAdapter extends FirestoreRecyclerAdapter<UserModel, UserAdapter.UserViewHolder> {
public UserAdapter(#NonNull FirestoreRecyclerOptions<UserModel> options) {
super(options);
}

holder.username.setText(model.getFullName());
holder.email.setText(model.getEmail());
holder.score.setText(model.getScore()+"");
holder.rank.setText(String.valueOf(position + 1));
Glide.with(holder.userImage.getContext())
.load(model.getUrl())
.into(holder.userImage);

You should call holder.getAdapterPosition only within the ViewHolder; instead you can simply use the parameter position passed in onBindViewHolder().
#Override
protected void onBindViewHolder(#NonNull UserAdapter.UserViewHolder holder, int position, #NonNull UserModel model) {
// .....
if(position == 0)
{
Glide.with(holder.firstPlace.getContext())
.load(model.getUrl())
.into(holder.firstPlace);

How to put RadioButton that is in LineaLayout inside a RadioGroup

I have six RadioButtons belonging to the same question, and I need to put them in some RadioGroup. But these RadioButtons is in some LinearLayouts. I tried to put one RadioGroup to each RadioButton, but i don't know what i need to do for it to work.

Try this solution..
class MyActivity extends Activity {
RadioButton _Rone, _Rtwo, _Rthree;
#Override
protected void onCreate(Bundle savedInstanceState) {
//after setContentView(.....)
_Rone = (RadioButton) findViewById(R.id.radio_one);
_Rtwo = (RadioButton) findViewById(R.id.radio_two);
_Rthree = (RadioButton) findViewById(R.id.radio_three);
_Rone.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
_Rone.setChecked(true);
_Rtwo.setChecked(false);
_Rthree.setChecked(false);
}
});
_Rtwo.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
_Rone.setChecked(false);
_Rtwo.setChecked(true);
_Rthree.setChecked(false);
}
});
_Rthree.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
_Rone.setChecked(false);
_Rtwo.setChecked(false);
_Rthree.setChecked(true);
}
});
// do code here
}`
by clicking on anyradio button the other's selection will reset.

ViewHolder not show a button in method onSwiped()

I have a big issues about onSwiped method and set a button's visibility to VISIBLE. Here my code Java Class :
#Override
public void onSwiped(RecyclerView.ViewHolder viewHolder, int swipeDir) {
mRecyclerView.getAdapter();
StepListAdapter.ViewHolder listViewHolder = (StepListAdapter.ViewHolder) viewHolder;
listViewHolder.itemView.setBackgroundColor(mContext.getResources().getColor(R.color.accent));
listViewHolder.titleView.setVisibility(View.GONE);
listViewHolder.locationView.setVisibility(View.GONE);
listViewHolder.status.setVisibility(View.GONE);
listViewHolder.undoButton.setVisibility(View.VISIBLE);
listViewHolder.undoButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
//Do something
}
});
}
And here my xml layout file:
<android.support.v7.widget.CardView
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:card_view="http://schemas.android.com/apk/res-auto"
android:id="#+id/view"

<TextView

android:layout_width="match_parent"
android:layout_height="wrap_content"
android:textSize="16sp"
android:ellipsize="end"
android:layout_gravity="center"
android:padding="5sp"
android:textColor="#color/dark_grey"
android:layout_below="#id/step_title_text"
android:text="#string/empty"/>
<ImageView
android:id="#+id/status_image"
android:layout_width="26dp"
android:layout_height="26dp"
android:layout_alignParentRight="true"
android:layout_alignParentTop="true"/>
<Button
android:id="#+id/undo_button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/undo"
android:textAllCaps="true"
android:visibility="gone"
android:textColor="#android:color/white"
android:layout_gravity="end|center_vertical"
android:layout_alignParentRight="true"
style="#style/Base.Widget.AppCompat.Button.Borderless"
/>
</RelativeLayout>
</android.support.v7.widget.CardView>
My problem is that when the method onSwiped was called, and after I setup the VISIBILITY of the button by Java code, the main card doesn't show the button .
Thanks a lot guys

I had the same problem ...
the problem disappeared after changing my code in fragment
from
#Override
public void onViewCreated(View view, #Nullable Bundle savedInstanceState) {
...
detailAdapter = new TitleAdapter(getChildFragmentManager(),getActivity());//remove this
...
}
on
#Override
public void onAttach(Context context) {
super.onAttach(context);
detailAdapter = new TitleAdapter(getActivity().getSupportFragmentManager (),getActivity());//add this
}
