For creating a fragment we only use two things:- Fragment class Fragment xml layout In the below discussed example we need to show different fragments on button click event. So, we will be creating two layout files and two different classes. Here goes the code for first Fragment: FirstFragment.java package com.example.fragementdemo; import android.app.Fragment; import android.os.Bundle; import android.view.LayoutInflater; import android.view.View; import android.view.ViewGroup; public class FirstFragment extends Fragment {

Create a new Project. Make a new folder named ‘Font’ into your assets folder Paste the font file into this folder Now add the below written lines into your Java file.        textview =(TextView)findViewById(R.id. text1 );        Typeface font = Typeface. createFromAsset (getAssets(), "font/Maximum.ttf" );        textview .setTypeface(font);

MainActivity.java(login Screen) package com.AndroidDevelopmentGuru.database_new; import java.util.List; import android.app.Activity; import android.content.Intent; import android.database.Cursor; import android.os.Bundle; import android.view.MenuItem; import android.view.View; import android.view.View.OnClickListener; import android.widget.Button; import android.widget.EditText; import android.widget.Toast; public class MainActivity extends Activity {                                 EditText user, pass;                 Button login, not_reg;                 DatabaseHandler db;           ...

For this we just need a class and we will programmatically create the Layouts. And after this we will add Buttons in each layout. package com.AndroidDevelopmentGuru.progmatic; import android.app.Activity; import android.graphics.Color; import android.os.Bundle; import android.view.Gravity; import android.widget.Button; import android.widget.LinearLayout; import android.widget.LinearLayout.LayoutParams; public class progmmatic extends Activity {     @Override     protected void onCreate(Bundle savedInstanceState) {         // TODO Auto-generated method stub         super.onCreate(savedInstanceState);                 //creating a Linear Layout         LinearLayout parent_layout = new LinearLayout(this);        

To show two different layout inside a parent layout we will be working with linear layout. You just need to specify the weight of child layouts. Here goes the code: activity_main.xml <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/rightLayout" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" >
