Mobile DevelopmentApps/ApplicationsAndroid

This example demonstrate about How to print number of paragraphs in textview in android.

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:gravity="center_horizontal"
   android:layout_marginTop="100dp"
   tools:context=".MainActivity">
   <TextView
      android:id="@+id/text"
      android:gravity="center"
      android:layout_width="wrap_content"
      android:layout_height="wrap_content">
   </TextView>
</LinearLayout>

In the above code, we have taken textview to show paragraph and toast will show the information about number of paragraphs.

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

package com.example.myapplication;

import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.widget.TextView;
import android.widget.Toast;

public class MainActivity extends AppCompatActivity {
   TextView text;
   @Override
   protected void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.activity_main);
      text = findViewById(R.id.text);
      text.setText("Lorem Ipsum is simply dummy text of the printing and typesetting industry.
                    Lorem Ipsum has been the industry's standard dummy text ever since the
                    1500s, when an unknown printer took a galley of type and scrambled it to
                    make a type specimen book. It has survived not only five centuries, but
                    also the leap into electronic typesetting, remaining essentially unchanged.
                    It was popularised in the 1960s with the release of Letraset sheets
                    containing Lorem Ipsum passages, and more recently with desktop publishing
                    software like Aldus PageMaker including versions of Lorem Ipsum.");
      String[] para = text.getText().toString().split("\r\n\r\n");
      Toast.makeText(MainActivity.this, "" + para.length, Toast.LENGTH_LONG).show();
   }
}
