Character and Word count in Android simple example

Here is the example of word count and character count in android using TextWatcher

Activity:


import android.graphics.Color;
import android.os.Bundle;
import android.support.v7.app.ActionBarActivity;
import android.text.Editable;
import android.text.TextWatcher;
import android.view.Menu;
import android.view.MenuItem;
import android.widget.EditText;
import android.widget.TextView;

public class CharacterCount extends ActionBarActivity implements TextWatcher {

EditText InputEDT;
TextView WordCountTXT,CharCountTXT;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_character_count);
InputEDT=(EditText)findViewById(R.id.editText1);
CharCountTXT=(TextView)findViewById(R.id.textView2);
WordCountTXT=(TextView)findViewById(R.id.textView1);
InputEDT.addTextChangedListener(this);
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.character_count, menu);
return true;
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {

return super.onOptionsItemSelected(item);
}

@Override
public void beforeTextChanged(CharSequence s, int start, int count,
int after) {
// TODO Auto-generated method stub

}

@Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
//CharCountTXT.setText(s.length());
//CharCountTXT.setTextColor(Color.GREEN);
}

@Override
public void afterTextChanged(Editable s) {
int slenght=s.length();
String input=InputEDT.getText().toString().trim().replaceAll("\n", "");
String[] wordCount=input.split("\\s");
WordCountTXT.setText("Word Count is: "+String.valueOf(wordCount.length));
CharCountTXT.setText("Character count is: "+String.valueOf(slenght));
CharCountTXT.setTextColor(Color.GREEN);

}
}

Layout :

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/container"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="com.sachinsandbhor.charactercount.CharacterCount"
    tools:ignore="MergeRootFrame" >

    <EditText
        android:id="@+id/editText1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentLeft="true"
        android:layout_alignParentRight="true"
        android:layout_alignParentTop="true"
        android:maxLines="2"
        android:ems="10" >

        <requestFocus />
    </EditText>

    <TextView
        android:id="@+id/textView1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_below="@+id/editText1"
        android:layout_margin="5dp"
        android:layout_centerHorizontal="true" />

    <TextView
        android:id="@+id/textView2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_below="@+id/textView1"
        android:layout_margin="5dp"
        android:layout_centerHorizontal="true" />

</RelativeLayout>
