What I have tried:

I have already successfully apllied it in windows and it worked perfectly, but trying to put
infuse it in android has been difficult. Please help me out with it.

Here is my code

Java

import android.app.*;
import android.os.*;
import android.view.*;
import android.widget.*;

public class SubActivity extends Activity 
{
@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.main2);
}

//From here is problem. Please help me in fixing it 
public void RevOnClick(View view)
{
EditText main2EditText1 =(EditText)findViewById(R.id.main2EditText1);
String sen = main2EditText1.getText().toString();
String[] senRev = sen.split("\\b");

for (int n = senRev.length - 1; n >= 0; n--) 
{

TextView main2TextView1 = (TextView)findViewById(R.id.main2TextView1);
main2TextView1.setText(senRev[n]);
}
}
}

By putting the setText() inside the for loop, it will always replace existing content with the one from subsequent iteration. That is the mistake. The correct way is to do the reversal of words in the for loop, then display the final reversed words as string in the edit text control only after the end of the for loop. Try this:

C#

String sen = "Welcome to Code Project";

String[] senRev = sen.split("\\b");

StringBuilder builder=new StringBuilder();

for (int n = senRev.length - 1; n >= 0; n--)
{
    builder.append(senRev[n]);
}

TextView main2TextView1 = (TextView)findViewById(R.id.main2TextView1);
main2TextView1.setText(builder.toString());
