How to Create Spalace Layout :-

Now create a activity and add following code :

1. XML File

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".SpalaceAct"
android:background="@drawable/side_nav_bar">

<ImageView
android:id="@+id/imageView2"
android:layout_width="match_parent"
android:layout_height="186dp"
android:layout_marginTop="150dp"
app:srcCompat="@mipmap/logo_image" />

<TextView
android:id="@+id/textView2"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="@+id/imageView2"
android:layout_marginTop="146dp"
android:gravity="center"
android:text="from"
android:textColor="#1C721C"
android:textSize="20dp" />

<TextView
android:id="@+id/textView3"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="@+id/textView2"
android:layout_marginTop="20dp"
android:gravity="center"
android:text="FACEBOOK"
android:textColor="#0FDB0F"
android:textSize="25dp" />

<ProgressBar
android:id="@+id/progressBar2"
style="?android:attr/progressBarStyle"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="@+id/imageView2"
android:layout_marginTop="55dp" />


</RelativeLayout>

2. Java file

package com.example.demodrawernaviga2;

import androidx.appcompat.app.AppCompatActivity;

import android.content.ClipData;
import android.content.Intent;
import android.os.Bundle;

public class SpalaceAct extends AppCompatActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_spalace);

Thread background = new Thread() {
public void run() {
try {
// Thread will sleep for 5 seconds
sleep(1*1000);

// After 5 seconds redirect to another intent
Intent i=new Intent(getBaseContext(),MainActivity.class);
startActivity(i);

//Remove activity
finish();
} catch (Exception e) {
}
}
};
// start thread
background.start();
}
}

How to Work with Recycler View in android :-

1. Open build.gradle and add recycler view dependency :-implementation 'com.android.support:recyclerview-v7:28.0.0'

Created A activity like MainAcvitiy :-

:- XML File

<?xml version="1.0" encoding="utf-8"?>

<androidx.recyclerview.widget.RecyclerView

xmlns:android="http://schemas.android.com/apk/res/android"

xmlns:tools="http://schemas.android.com/tools"

android:layout_width="match_parent"

android:layout_height="match_parent"

android:scrollbars="vertical"

android:id="@+id/recyclerView">

</androidx.recyclerview.widget.RecyclerView>

:- JAVA File

package com.example.demorecycler;

import android.os.Bundle;

import androidx.appcompat.app.AppCompatActivity;
import androidx.recyclerview.widget.LinearLayoutManager;
import androidx.recyclerview.widget.RecyclerView;

public class MainActivity extends AppCompatActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
MyListData[] myListData = new MyListData[] {
new MyListData("Email", android.R.drawable.ic_dialog_email),
new MyListData("Info", android.R.drawable.ic_dialog_info),
new MyListData("Delete", android.R.drawable.ic_delete),
new MyListData("Dialer", android.R.drawable.ic_dialog_dialer),
new MyListData("Alert", android.R.drawable.ic_dialog_alert),
new MyListData("Map", android.R.drawable.ic_dialog_map),
new MyListData("Email", android.R.drawable.ic_dialog_email),
new MyListData("Info", android.R.drawable.ic_dialog_info),
new MyListData("Delete", android.R.drawable.ic_delete),
new MyListData("Dialer", android.R.drawable.ic_dialog_dialer),
new MyListData("Alert", android.R.drawable.ic_dialog_alert),
new MyListData("Map", android.R.drawable.ic_dialog_map),
};

RecyclerView recyclerView = (RecyclerView) findViewById(R.id.recyclerView);
MyListAdapter adapter = new MyListAdapter(myListData);
recyclerView.setHasFixedSize(true);
recyclerView.setLayoutManager(new LinearLayoutManager(this));
recyclerView.setAdapter(adapter);
}

}

3. Created A list_item.xml

<?xml version="1.0" encoding="utf-8"?>

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:id="@+id/relativeLayout"

android:layout_width="match_parent"

android:layout_height="?android:attr/listPreferredItemHeightLarge"

android:background="@drawable/border">

<ImageView

android:id="@+id/imageView"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:layout_centerVertical="true"

android:layout_alignParentStart="true"

android:layout_alignParentLeft="true"

android:contentDescription="Icon" />

<TextView

android:id="@+id/textView"

android:layout_width="wrap_content"

android:layout_height="match_parent"

android:layout_toEndOf="@id/imageView"

android:layout_toRightOf="@id/imageView"

android:gravity="center_vertical"

android:textSize="16sp"/>

</RelativeLayout>

4. Created A MyListAdapter Java File :-

package com.example.demorecycler;

import android.view.LayoutInflater;

import android.view.View;

import android.view.ViewGroup;

import android.widget.ImageView;

import android.widget.RelativeLayout;

import android.widget.TextView;

import android.widget.Toast;

import androidx.recyclerview.widget.RecyclerView;

public class MyListAdapter extends RecyclerView.Adapter<MyListAdapter.ViewHolder>{

private MyListData[] listdata;

// RecyclerView recyclerView;

public MyListAdapter(MyListData[] listdata) {

this.listdata = listdata;

}

@Override

public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {

LayoutInflater layoutInflater = LayoutInflater.from(parent.getContext());

View listItem= layoutInflater.inflate(R.layout.list_item, parent, false);

ViewHolder viewHolder = new ViewHolder(listItem);

return viewHolder;

}

@Override

public void onBindViewHolder(ViewHolder holder, int position) {

final MyListData myListData = listdata[position];

holder.textView.setText(listdata[position].getDescription());

holder.imageView.setImageResource(listdata[position].getImgId());

holder.relativeLayout.setOnClickListener(new View.OnClickListener() {

@Override

public void onClick(View view) {

Toast.makeText(view.getContext(),"click on item: "+myListData.getDescription(),Toast.LENGTH_LONG).show();

}

});

}

@Override

public int getItemCount() {

return listdata.length;

}

public static class ViewHolder extends RecyclerView.ViewHolder {

public ImageView imageView;

public TextView textView;

public RelativeLayout relativeLayout;

public ViewHolder(View itemView) {

super(itemView);

this.imageView = (ImageView) itemView.findViewById(R.id.imageView);

this.textView = (TextView) itemView.findViewById(R.id.textView);

relativeLayout = (RelativeLayout)itemView.findViewById(R.id.relativeLayout);

}

5. Created A MyListData Java File :-

package com.example.demorecycler;

public class MyListData{

private String description;

private int imgId;

public MyListData(String description, int imgId) {

this.description = description;

this.imgId = imgId;

}

public String getDescription() {

return description;

}

public void setDescription(String description) {

this.description = description;

}

public int getImgId() {

return imgId;

}

public void setImgId(int imgId) {

this.imgId = imgId;

}

how to create custom listview in android :-

1. Create a Activity MainActivity :-

:- in XML file

<?xml version="1.0" encoding="utf-8"?>

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

xmlns:app="http://schemas.android.com/apk/res-auto"

xmlns:tools="http://schemas.android.com/tools"

android:layout_width="match_parent"

android:layout_height="match_parent"

tools:context=".MainActivity"

android:background="@drawable/side_nav_bar">

<ListView

android:id="@+id/study_mode_list_item"

android:layout_width="match_parent"

android:layout_height="match_parent"

android:layout_marginLeft="8dp"

android:divider="#8A46A005"

android:dividerHeight="1.5dp"

android:footerDividersEnabled="true"

android:layout_marginRight="8dp"/>

</RelativeLayout>

In JAVA File :-

package com.example.demodrawernaviga2;

import androidx.appcompat.app.AppCompatActivity;

import android.content.Intent;

import android.os.Bundle;

import android.view.View;

import android.widget.AdapterView;

import android.widget.LinearLayout;

import android.widget.ListView;

import android.widget.Toast;

import com.example.demodrawernaviga2.R;

public class CategoryStudy extends AppCompatActivity {

int book[] = {R.drawable.stude_mode, R.drawable.stude_mode, R.drawable.stude_mode,

R.drawable.stude_mode, R.drawable.stude_mode, R.drawable.stude_mode, R.drawable.stude_mode, R.drawable.stude_mode, R.drawable.stude_mode,

R.drawable.stude_mode, R.drawable.stude_mode, R.drawable.stude_mode,

R.drawable.stude_mode};

String subject[] = {"Hindi","English","Science","Maths","Biology","Physics","Chemistry","Geography","Citizenship",

"Business Studies","Psychology","Sociology","Economics"};

int next[] = {R.drawable.next, R.drawable.next, R.drawable.next, R.drawable.next, R.drawable.next, R.drawable.next,

R.drawable.next, R.drawable.next, R.drawable.next, R.drawable.next, R.drawable.next, R.drawable.next,

R.drawable.next};

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_category_study);

ListView listView = (ListView)findViewById(R.id.study_mode_list_item);

CustomAdapterStudyMode customAdapter = new CustomAdapterStudyMode(getApplicationContext(),book,subject,next);

listView.setAdapter(customAdapter);

listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {

@Override

public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {

switch (i){

case 1:

Intent in1=new Intent(getApplicationContext(),GameCate.class);

startActivity(in1);

break;

case 2:

Intent in2=new Intent(getApplicationContext(),MainActivity.class);

startActivity(in2);

break;

case 3:

Intent in3=new Intent(getApplicationContext(),SpalaceAct.class);

startActivity(in3);

break;

case 4:

Intent in4=new Intent(getApplicationContext(),QuizCate.class);

startActivity(in4);

break;

}

//show the selected image in toast according to position

}

});

}

2. Create a activity_list.xml File

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:orientation="vertical"

android:layout_width="match_parent"

android:layout_height="match_parent"

android:background="@drawable/side_multi_color_list">

<LinearLayout

android:layout_width="match_parent"

android:layout_height="wrap_content"

android:orientation="horizontal"

android:layout_marginTop="15dp"

android:layout_marginBottom="15dp"

android:weightSum="100">

<ImageView

android:id="@+id/study_mode"

android:layout_width="40dp"

android:layout_height="40dp"

android:src="@drawable/stude_mode"

android:layout_weight="20"

android:elevation="5dp"/>

<TextView

android:id="@+id/study_mode_text"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:text="Hindi"

android:textStyle="italic|bold"

android:fontFamily="serif-monospace"

android:textSize="20dp"

android:layout_weight="70"

android:layout_marginTop="10dp"

android:textColor="#ffffff"/>

<ImageView

android:id="@+id/study_mode_next"

android:layout_width="20dp"

android:layout_height="25dp"

android:src="@drawable/next"

android:layout_weight="10"

android:layout_marginTop="7dp"

android:elevation="5dp"/>

</LinearLayout>

3. Now Create a CustomAdapter JAVA Class :-

package com.example.demodrawernaviga2;

import android.content.Context;

import android.view.LayoutInflater;

import android.view.View;

import android.view.ViewGroup;

import android.widget.BaseAdapter;

import android.widget.ImageView;

import android.widget.TextView;

public class CustomAdapterStudyMode extends BaseAdapter {

Context context;

int book[];

String subject[];

int next[];

LayoutInflater inflter;

public CustomAdapterStudyMode(Context applicationContext, int[] book, String[] subject, int[] next) {

this.context = context;

this.book = book;

this.subject = subject;

this.next = next;

inflter = (LayoutInflater.from(applicationContext));

}

@Override

public int getCount() {

return subject.length;

}

@Override

public Object getItem(int i) {

return null;

}

@Override

public long getItemId(int i) {

return 0;

}

@Override

public View getView(int i, View view, ViewGroup viewGroup) {

view = inflter.inflate(R.layout.activity_study_list, null);

ImageView icon = (ImageView) view.findViewById(R.id.study_mode);

TextView tv = (TextView) view.findViewById(R.id.study_mode_text);

ImageView icon1 = (ImageView) view.findViewById(R.id.study_mode_next);

icon.setImageResource(book[i]);

tv.setText(subject[i]);

icon1.setImageResource(next[i]);

return view;

}
