How to implement Android TextInputLayout

Android Apps/Applications Mobile Development

Before getting into example, we should know what is TextInputLayout in android. TextInputLayout is extended by Linear Layout. It going to act as a wrapper for edit text and shows flatting hint animation for edit text.

This example demonstrate about how to implement Android TextInputLayout.

Step 1 − Create a new project in Android Studio, go to File ⇒ New Project and fill all required details to create a new project.

Step 2 − Add the following code to res/layout/activity_main.xml.

<?xml version = "1.0" encoding = "utf-8"?> <LinearLayout 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"    tools:context = ".MainActivity"    android:background = "#dde4dd"    android:orientation = "vertical">    <android.support.design.widget.TextInputLayout       android:layout_width = "match_parent"       android:layout_height = "wrap_content"       android:id = "@+id/layoutEmail"       android:layout_marginTop = "8dp"       android:layout_marginStart = "8dp"       android:layout_marginEnd = "8dp"       style = "@style/Widget.MaterialComponents.TextInputLayout.FilledBox">       <android.support.design.widget.TextInputEditText          android:layout_width = "match_parent"          android:layout_height = "wrap_content"          android:id = "@+id/email"          android:hint = "Enter Email id"          android:inputType = "textEmailAddress"/>    </android.support.design.widget.TextInputLayout>    <android.support.design.widget.TextInputLayout       android:layout_width = "match_parent"       android:layout_height = "wrap_content"       android:id = "@+id/layoutPassword"       android:layout_marginTop = "8dp"       android:layout_marginStart = "8dp"       android:layout_marginEnd = "8dp"       style = "@style/Widget.MaterialComponents.TextInputLayout.FilledBox">       <android.support.design.widget.TextInputEditText          android:layout_width = "match_parent"          android:layout_height = "wrap_content"          android:id = "@+id/password"          android:hint = "Password"          android:inputType = "textPassword"/>    </android.support.design.widget.TextInputLayout>    <Button       android:id = "@+id/click"       android:layout_width = "wrap_content"       android:layout_height = "wrap_content"       android:layout_gravity = "center"       android:text = "Click"></Button> </LinearLayout>

In the above code we have given two TextInputEditText and one button. when you click on button it will take data from edit text and show on Toast.

Step 3 − Add the following code to src/MainActivity.java

package com.example.andy.myapplication; import android.graphics.Point; import android.support.v7.app.AppCompatActivity; import android.os.Bundle; import android.view.TextureView; import android.view.View; import android.widget.Button; import android.widget.EditText; import android.widget.TextView; import android.widget.Toast; public class MainActivity extends AppCompatActivity {    EditText email,password;    @Override    protected void onCreate(Bundle savedInstanceState) {       super.onCreate(savedInstanceState);       setContentView(R.layout.activity_main);       email = findViewById(R.id.email);       password = findViewById(R.id.password);       Button click = findViewById(R.id.click);       click.setOnClickListener(new View.OnClickListener() {          @Override          public void onClick(View v) {             if(!email.getText().toString().isEmpty()&&(!password.getText().toString().isEmpty())) {                Toast.makeText(MainActivity.this, "you have entered email id " +                                     email.getText().toString() + "Password " + password.getText().toString(), Toast.LENGTH_LONG).show();             } else {                email.setError("Please Enter Email id");                password.setError("Please Enter Pass word");             }          }       });    } }

Step 4 − Open build.gradle and add design support library dependency.

apply plugin: 'com.android.application' android {    compileSdkVersion 28    defaultConfig {       applicationId "com.example.andy.myapplication"       minSdkVersion 15       targetSdkVersion 28       compileSdkVersion 28       versionCode 1       versionName "1.0"       testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"    }    buildTypes {       release {          minifyEnabled false          proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'       }    } } dependencies {    implementation fileTree(dir: 'libs', include: ['*.jar'])    implementation 'com.android.support:appcompat-v7:28.0.0'    implementation 'com.android.support:design:28.0.0'    implementation 'com.android.support.constraint:constraint-layout:1.1.3'    testImplementation 'junit:junit:4.12'    androidTestImplementation 'com.android.support.test:runner:1.0.2'    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2' }

Let's try to run your application. I assume you have connected your actual Android Mobile device with your computer. To run the app from android studio, open one of your project's activity files and click Run icon from the toolbar. Select your mobile device as an option and then check your mobile device which will display your default screen −
