app showing some irrelevant Text instead of a Textview

I am developing an android app, it was working fine till i add textview into main activity layout.
All images are being shown. But instead of textview an irrelevant is being shown on display screen.
Below is the code from mainactivity.java.
import android.content.Intent;
import android.database.sqlite.SQLiteDatabase;
import android.support.v7.app.AlertDialog;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.text.InputType;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.ImageButton;
import android.widget.TextView;
import android.widget.Toast;
import java.text.SimpleDateFormat;
import java.util.ArrayList;
import java.util.Calendar;
public class MainActivity extends AppCompatActivity {
ImageButton showBalDialog, showExpDialog, showIncomebtn, showExpbtn;
TextView bal_dialog, total_incomes;
public static final String DB_name = "mydb";
DatabaseHelper m_db;
private String amnt, src, exp, rzn;
private String incomes = "sum";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
m_db = new DatabaseHelper(this);
showBalDialog = findViewById(R.id.btnshowBalDialog);
showExpDialog = findViewById(R.id.btnshowExpDialog);
showIncomebtn = findViewById(R.id.btnshowIncomes);
showExpbtn = findViewById(R.id.btnshowExpenses);
total_incomes = findViewById(R.id.totalincomes);
incomes = String.valueOf(total_incomes);
total_incomes.setText(incomes);
}
}
Below is the code from activity_main.xml
<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout

android:layout_height="150dp"
android:layout_marginEnd="20dp"

app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintTop_toBottomOf="#id/btnshowExpDialog"

<TextView
android:id="#+id/totalincomes"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:layout_marginTop="20dp"
android:text="TextView"
app:layout_constraintTop_toBottomOf="#id/btnshowIncomes"
app:layout_constraintStart_toStartOf="parent">
</TextView>
</android.support.constraint.ConstraintLayout>
And below what is i am getting instead of Textview on app gui.

You have to do this:
total_incomes.setText(incomes);
your incomes value is already in String no need to use String.valueOf()
instead of
incomes = String.valueOf(total_incomes);
total_incomes.setText(incomes);

total_incomes is the Textview, you are binding the TextView with R.id.totalincome which is present in xml.
incomes = String.valueOf(total_incomes);
total_incomes.setText(incomes);
You are fetching the string value of total_incomes and store it in incomes and the same value you set on total_incomes. so in short you are setting textview id.

RecyclerView Margin

i am developing application for home security. One of the feature, that must be implemented is the ability to see connected devices (for sending notifications, blocking access, etc). So far, i've been able to create RecyclerView list of the devices, everything is perfect (for me), except that cards in this list have no spacing between them.

Can anyone please help me solve this problem? Thank you very much in advance!

In your RecyclerView Adapter onCreateViewHolder:
replace:
View view = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.connected_devices_layout, null);
with:
View view = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.connected_devices_layout, viewGroup, false);
Or you can use RecyclerView.addItemDecoration(ItemDecoration decor).

I have written my activity java it itself creates the image buttons in a gridview. But I use like this I want to use in such way that I call my customs layout in different activities because the layout is same only the IDs and some images will change.

If I understand it right - you have a custom design layout with buttons and you want to use this same layout in other screen as well.
You don't need to rename anything, just put the layout in a separate xml, let's say CommonButtonLayout.xml. This should contain like this:
<?xml version="1.0" encoding="utf-8"?>
<merge xmlns:android="http://schemas.android.com/apk/res/android" >
.... your layout .....
</merge>

Fragment and Toggle Button

I am very new to Android. I am trying to add a simple toggle button to a class which extends Fragment class.
I tried everything but I could not get it working. I managed to add a normal button but that is not useful for me.
All I want is add a toggle button.
Please help me.
Thanks all
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#cccccc" >
<TextView
android:id="#+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
android:layout_marginTop="18dp"
android:text="Light Tab"
android:textColor="#333333"
android:textSize="20sp" />
<Button
android:id="#+id/fragment_button"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignLeft="#+id/textView1"
android:layout_alignRight="#+id/textView1"
android:layout_below="#+id/textView1"
android:layout_marginTop="61dp"
android:text="#string/btn_fragment" />
</RelativeLayout>
package com.baris.smartgame;
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.app.Activity;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.Toast;
public class Light extends Fragment {
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.light, container, false);
((Button) view.findViewById(R.id.fragment_button))
.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
Activity activity = getActivity();
if (activity != null) {
Toast.makeText(activity,
R.string.toast_you_just_clicked_a_fragment,
Toast.LENGTH_SHORT).show();
}
}
});
return view;
}
}

Use This as an Example :
<LinearLayout
android:id="#+id/txtDayTypes"
android:layout_below="#+id/main_header"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal" >
<ToggleButton
android:id="#+id/tglDay1"
android:layout_width="160dp"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:text="Saturday"
android:textOn="Saturday"
android:textOff="Saturday"
android:checked="true"/>
</LinearLayout>
and you can Access it by :
if(currentButton != R.id.tglDay1) ((ToggleButton)findViewById(R.id.tglDay1)).setChecked(false);
