This example demonstrates how do I hide soft keyboard on android after clicking outside edittext.

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"
   android:orientation="vertical"
   android:padding="16dp"
   tools:context="MainActivity">
   <TextView
      android:id="@+id/textView"
      android:layout_width="wrap_content"
      android:layout_height="wrap_content"
      android:layout_gravity="center_horizontal"
      android:hint="Enter text here"
      android:textSize="20sp" />
   <EditText
      android:id="@+id/editText"
      android:layout_width="match_parent"
      android:layout_height="wrap_content" />
   <Button
      android:layout_width="wrap_content"
      android:layout_height="wrap_content"
      android:layout_gravity="center_horizontal"
      android:onClick="setText"
      android:text="Set Text"
      android:textStyle="bold"/>
</LinearLayout>

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

import android.content.Context;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.view.inputmethod.InputMethodManager;
import android.widget.EditText;
import android.widget.TextView;
public class MainActivity extends AppCompatActivity {
   EditText editText;
   TextView textView;
   @Override
   protected void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.activity_main);
      editText = findViewById(R.id.editText);
      textView = findViewById(R.id.textView);
   }
   public void setText(View view){
      String newText = editText.getText().toString();
      textView.setText(newText);
      closeKeyBoard();
   }
   private void closeKeyBoard(){
      View view = this.getCurrentFocus();
      if (view != null){
         InputMethodManager imm = (InputMethodManager)
         getSystemService(Context.INPUT_METHOD_SERVICE);
         imm.hideSoftInputFromWindow(view.getWindowToken(), 0);
      }
   }
}

Step 4 - Add the following code to androidManifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
   package="app.com.sample">
   <application
      android:allowBackup="true"
      android:icon="@mipmap/ic_launcher"
      android:label="@string/app_name"
      android:roundIcon="@mipmap/ic_launcher_round"
      android:supportsRtl="true"
      android:theme="@style/AppTheme">
      <activity android:name=".MainActivity">
         <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
         </intent-filter>
      </activity>
   </application>
</manifest>

Select your mobile device as an option and then check your mobile device which will display your default screen –
