NavigationView example in Android

Hi guys, You can use NavigationView from android material design for slide menu in android.


DrawerLayout xml 
<android.support.v4.widget.DrawerLayout 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:id="@+id/drawer_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fitsSystemWindows="true"
    tools:openDrawer="start">

    <include
        layout="@layout/app_bar_main"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />


    <android.support.design.widget.NavigationView
        android:id="@+id/navigation_view"
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        android:fitsSystemWindows="true"
        app:headerLayout="@layout/drawer_header"
        app:itemIconTint="@color/colorPrimary"
        app:itemTextAppearance="@layout/menu_text_style"
        app:menu="@menu/drawer" />

</android.support.v4.widget.DrawerLayout>
And your drawer header is normal layout, sample header layout drawer_header.xml 
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:gravity="center_vertical"
    android:padding="@dimen/activity_vertical_margin"
    android:background="@drawable/bg"
    android:orientation="horizontal">

    <ImageView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:contentDescription="@string/app_name"
        android:src="@drawable/ic_account_circle_white_24dp" />

    <TextView
        android:id="@+id/txtName"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginLeft="6dp"
        android:layout_marginStart="6dp"
        android:textAppearance="@style/TextAppearance.AppCompat.Headline"
        android:textColor="@android:color/white" />

</LinearLayout>
And your drawer menu is normal menu resource, sample menu resource code menu.xml 
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
    <group android:checkableBehavior="single">
        <item
            android:id="@+id/navigation_item_1"
            android:icon="@drawable/ic_home_white_24dp"
            android:title="@string/title_home" />
        <item
            android:id="@+id/navigation_item_2"
            android:icon="@drawable/ic_bookmark_white_24dp"
            android:title="@string/title_bookmarks" />
        <item
            android:id="@+id/navigation_item_3"
            android:icon="@drawable/ic_favorite_white_24dp"
            android:title="@string/title_favorite" />
        <item
            android:id="@+id/navigation_item_4"
            android:icon="@drawable/ic_payment_white_24dp"
            android:title="@string/title_payment" />
        <item
            android:id="@+id/navigation_item_5"
            android:icon="@drawable/ic_settings_white_24dp"
            android:title="@string/title_settings" />
    </group>
</menu>
And you can get this header layout in your java code as like 
NavigationView navigationView = (NavigationView) findViewById(R.id.navigation_view);
TextView txtName = (TextView) navigationView.getHeaderView(0).findViewById(R.id.txtName);
txtName.setText(getResources().getString(R.string.title_name));
And you have to implement NavigationView.OnNavigationItemSelectedListener to access the click event of menu items like, 
navigationView.setNavigationItemSelectedListener(this);
And, Yes, this interface has the method, it should be implemented as like, 
    @Override
    public boolean onNavigationItemSelected(MenuItem item) {
        int id = item.getItemId();
        int position = 0;
        switch (id) {
            case R.id.navigation_item_1:
                mTitle = getString(R.string.title_home);
                position = 0;
                break;
            case R.id.navigation_item_2:
                mTitle = getString(R.string.title_bookmarks);
                position = 1;
                break;
            case R.id.navigation_item_3:
                mTitle = getString(R.string.title_favorite);
                position = 2;
                break;
            case R.id.navigation_item_4:
                mTitle = getString(R.string.title_payment);
                position = 3;
                break;
            case R.id.navigation_item_5:
                mTitle = getString(R.string.title_settings);
                position = 4;
                break;
        }
        if (getSupportActionBar() != null)
            getSupportActionBar().setTitle(mTitle);
        DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
        drawer.closeDrawer(GravityCompat.START);
        
        FragmentManager fragmentManager = getSupportFragmentManager();
        fragmentManager.beginTransaction()
                .replace(R.id.container, PlaceholderFragment.newInstance(position + 1))
                .commit();
        
        return true;
    }

Simple example of using Spinner in Kotlin | Android

Though Kotlin has lot massive features to speedup the development time, here is the simple way of using Spinner in Android. In Kotlin we don't need to declare and initialize Spinner. We can simply access the id of Spinner from xml. Ex : import android.os.Bundle import android.support.v7.app.AppCompatActivity import android.view.View import android.widget.AdapterView import android.widget.ArrayAdapter import android.widget.Toast import android.widget.Toast.LENGTH_LONG import kotlinx.android.synthetic.main.activity_main.* class MainActivity : AppCompatActivity() { override fun onCreate(savedInstanceState: Bundle?) { super.onCreate(savedInstanceState) setContentView(R.layout.activity_main) //String array. val myStrings = arrayOf("One", "Two", "Three", "Four", "Five") //Adapter for spinner mySpinner.adapter = ArrayAdapter(this, android.R.layout.simple_spinner_dropdown_i...

Set limit for fraction in decimal numbers in EditText

            Already we know that we can set which type of input the edittext should accept from user using android:inputType="numberDecimal" But there is no predefined function to set the limit for the edittext to How many digit it should accept after the decimal point from user . We can achieve this by using TextWatcher . Full code example. Following program creates a Decimal Filter. DecimalFilter.java import android.text.Editable; import android.text.InputFilter; import android.text.TextWatcher; import android.view.KeyEvent; import android.view.View; import android.view.View.OnKeyListener; import android.widget.EditText; public class DecimalFilter implements TextWatcher { int count= -1 ; EditText et; Activity activity; public DecimalFilter(EditText edittext, Activity activity) { et = edittext; this.activity = activity; } public void afterTextChanged(Editable s) { if (s.length() > 0) { String str = et.get...
