Activity's layout overwrites another activity's layout

Activity's layout overwrites another activity's layout - java

I have this weird problem that I have no idea where it's coming from.
I am making recipes app and I am using SQLite to display image, description and favorite check box. For recipe instructions I am not using SQLite , instead I am using TextView.
In my app I have two activities BreakfastActivity and Breakfast2Activity with their layouts that displays content which I mentioned above.The problem is that Breakfast Activity's XML code overwrites BreakfastActivity2 layout.
Note: The information that coming from database does't overwrite , but the one that comes from xml does.
I checked java activities if they use same layouts and if the layouts use the same context. Everything seems fine. I can't figure out where it can be potential problem.
Any Help would be appreciated.
This is activity_breakfast xml.

Android-Studio, EditText inside RecyclerView inside CustomDialog focus issue

I have a problem with the focus. Everytime I click in the EditText I can write 1 character and then it loses the focus.
I´ve searched and I found some solutions if my EditText is inside a RecyclerView, but those don´t work with my project. I suspect that this is because my EditText is inside a RecyclerView which is inside a CustomDialog.
If someone know how to solve this it would be great :D
Edit:
This is the xml code of the CustomDialog that contains the RecyclerView:

android:hint="0.00"
android:inputType="numberDecimal"
android:minHeight="48dp" />
</LinearLayout>
</androidx.cardview.widget.CardView>
</androidx.constraintlayout.widget.ConstraintLayout>

We put requestFocus() and requestFocusFromTouch() and it works:
#personGasto is the editText
override fun afterTextChanged(p0: Editable?) {
#...
#some code
#...
personGasto.requestFocus()
personGasto.requestFocusFromTouch()
}

Replace fragment inside fragment :Exception No view found for id 0x

I have one fragment and I try to replace some another fragment in my layout.Here is a fragment replace code
public static void replace(FragmentManager fm, Fragment fragment, int container, String tag) {
FragmentTransaction fragmentTransaction = fm.beginTransaction();
fragmentTransaction.replace(container, fragment, tag);
fragmentTransaction.commit();
}
Here is a main code
if (cardList != null && cardList.isEmpty()) {
hideDialog(pDialog);
drawavleView.setDrawerLockMode(DrawerLayout.LOCK_MODE_LOCKED_CLOSED);
norecordfragment = new NoRecordFragment();
norecordfragment.setAvatar(R.drawable.ic_card_nocard);
norecordfragment.setText(getActivity().getString(R.string.u_cards_no_data_text));
norecordfragment.setButtontext(getActivity().getString(R.string.u_cards_no_data_action));
norecordfragment.setAllowToShowAddAction(false);
floatingActionButton.setVisibility(View.VISIBLE);
FragmentUtils.replace(getActivity().getSupportFragmentManager(), norecordfragment,
R.id.upload_main_layout_upload,"norecordfragment");
}

I don't know why in some devices I have this exception.
Exception java.lang.IllegalArgumentException: No view found for id 0x7f09052f (com.me.myapp:id/upload_main_layout_upload) for fragment NoRecordFragment{5309279 #4 id=0x7f09052f norecordfragment}
As you can see, I tried to replace my custom fragment inside upload_main_layout_upload layout, but I have this exception. What am I doing wrong? Thanks.

To implement a Fragment inside another layout, you need to have the layout that you are showing inside the Fragment in another fragment_layout.xml file. So you need to modify your current layout as follows.
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#ffffff"
android:fitsSystemWindows="false">
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fillViewport="true"
android:minHeight="#dimen/u_base_min_height">
<RelativeLayout
android:id="#+id/upload_main_layout_upload"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#ffffff"/>
</ScrollView>
<LinearLayout
android:id="#+id/floating_action_bar_transparent"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#4D000000"
android:clickable="true"
android:orientation="vertical"
android:visibility="gone" />
<android.support.design.widget.FloatingActionButton xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/floating_action_bar"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="bottom|end"
android:layout_margin="#dimen/fab_margin"
android:src="#drawable/ic_add_white"
app:backgroundTint="#48c9ff" />
</android.support.design.widget.CoordinatorLayout>
And take the content inside the RelativeLayout outside of this layout and create another layout which will be used in your Fragment to get views from there.
Here's a sample fragment_layout.xml.
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/lay_v3"
android:layout_width="match_parent"
android:layout_height="match_parent"

android:orientation="vertical">

android:id="#+id/upload_header_layout"
android:layout_width="match_parent"
android:layout_height="#dimen/transfer_headerView_height"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"
android:layout_alignParentTop="true"
android:background="#f2f2f2" />
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginLeft="#dimen/u_common_margin_left"
android:layout_marginRight="#dimen/u_common_margin_left"
android:layout_marginTop="#dimen/withdrow_change_card_height"
android:orientation="vertical">

android:layout_height="#dimen/u_widget_height"
android:background="#drawable/edittext_input_background_not_focus"
android:orientation="horizontal">

android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_marginBottom="7dp"
android:layout_marginLeft="5dp"
android:layout_weight="0.65"
android:background="#null"
android:gravity="left"
android:hint="0.00"
android:imeOptions="actionDone"
android:inputType="numberDecimal"
android:maxLines="1"
android:singleLine="true"
android:textColor="#4d4d4d"
android:textColorHint="#b2b2b2"

android:layout_height="match_parent"

android:layout_centerVertical="true"
android:background="#drawable/edittext_input_background_not_focus" />
<ImageView
android:id="#+id/u_open_spinner"
android:layout_width="wrap_content"
android:layout_height="wrap_content"

You have too many nested layouts inside one as far as I can see. You need to rearrange your layouts as per your requirement and transaction flows between Activity and Fragments.

ScrollView top part is cut off when I added adjustPan so keyboard won't overlap EditText

I have a ScrollView (with a RecyclerView inside) and a RelativeLayout after it which contains EditText. I added
android:windowSoftInputMode="stateAlwaysHidden|adjustPan"
for the activity in my manifest file because my keyboard overlaps the EditText but in effect, whenever the keyboard is active, the top part of my ScrollView is cut off.
I have tried using NestedScrollView and setting RelativeLayout android:layout_height="wrap_content" and android:layout_gravity="center" but that doesn't work. Below is the snippet of my code:
<RelativeLayout

cannot resolve symbol android on TabHost methods

I'm new to android development and i'm working on TabHost layout with three tabs so i made my xml file :
<TabHost
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/ntm">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<TabWidget
android:id="#android:id/tabs"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="0"/>
<FrameLayout
android:id="#android:id/tabcontent"
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:id="#+id/Present"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<TableLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<TableRow
android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView
android:text="Simple"
android:gravity="center"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/textView24"
android:layout_weight="1"/>
<TextView
android:text="Continuous"
android:gravity="center"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/textView23"
android:layout_weight="1"/>
<TextView
android:text="Perfect Simple"
android:gravity="center"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/textView15"
android:layout_weight="1"/>
<TextView
android:text="Perfect Continuous"
android:gravity="center"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/textView8"
android:layout_weight="1"/>
</TableRow>
<TableRow
android:layout_width="match_parent"
android:layout_height="match_parent" />
</TableLayout>
</LinearLayout>
<LinearLayout
android:id="#+id/Past"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<TextView
android:text="NTM1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/textView25" />
</LinearLayout>
<LinearLayout
android:id="#+id/Future"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<TextView
android:text="NTM2"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/textView26" />
</LinearLayout>
</FrameLayout>
</LinearLayout>
</TabHost>
</LinearLayout>
and here is my code in the concerned activity to initialize the tabs :
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.time);
}
TabHost tab =(TabHost) findViewById(R.id.ntm);
tab.setup();
TabHost.TabSpec spec1 = tab.newTabSpec("PRESENT");
spec1.setIndicator("PRESENT");
spec1.setContent(R.id.Present);
tab.addTab(spec1);
TabHost.TabSpec spec2 = tab.newTabSpec("PAST");
spec2.setIndicator("PAST");
spec2.setContent(R.id.Past);
tab.addTab(spec2);
TabHost.TabSpec spec3 = tab.newTabSpec("FUTURE");
spec3.setIndicator("FUTURE");
spec3.setContent(R.id.Future);
tab.addTab(spec3);
I get this error:
cannot resolve symbol
On every methods like tab.setup() or all methods applicables on TabHost and TabSpec objects.
I've tried to copy/paste my code in the main activity and there I've got no errors but the application instantly crashes

I've found my mistake, i had not put the initializing code into the method onCreate i've got no more errors

How to make the bottom Sheet adjust its size on different screen sizes?

I have tried to make a bottom sheet and it contains two rows , I want the first row only to be visible to the user when he opens the app .
When I ran the app on the emulator it was great but when i tried to run it on a real device (Samsung J7) the first row and a part of the second row appeared.
My question is how can I adjust my code so only 1 row appears on different screen sizes

SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager()
.findFragmentById(R.id.map);

BottomSheetBehavior bottomSheetBehavior = bottomSheetBehavior.from(bottomSheet);
bottomSheetBehavior.setPeekHeight(300);
bottomSheetBehavior.setState(BottomSheetBehavior.STATE_COLLAPSED);

Your single card has a height (according to your layout):
#dimen/card_view_height
Pass this value to setPeekHeight function:
bottomSheetBehavior.setPeekHeight(getContext().getResources().getDimension(R.dimen.card_view_height));
