In This tutorials we will implement dynamic text View design . explain below

MainActivity.java
...................................................................................................................................................................

package com.androidbeginner.testcode;

import java.util.ArrayList;

import android.app.Activity;
import android.graphics.Color;
import android.os.Bundle;
import android.view.Gravity;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.ViewGroup.LayoutParams;
import android.widget.LinearLayout;
import android.widget.TextView;

public class MainActivity extends Activity {
LinearLayout ln;
ArrayList<String> ParameterList = new ArrayList<String>();

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
ln = (LinearLayout) findViewById(R.id.layouts);

final TextView tutorial = new TextView(getApplication());
tutorial.setText("AndroidBeginner");
tutorial.setTextSize(40);
tutorial.setGravity(Gravity.CENTER);
tutorial.setTextColor(Color.BLUE);
ln.addView(tutorial);

/*
* Add items in arraylist
*/

ParameterList.add("item1");
ParameterList.add("item2");
ParameterList.add("item3");
ParameterList.add("item4");
ParameterList.add("item5");
ParameterList.add("item6");
for (int i = 0; i < ParameterList.size(); i++) {

String id = ParameterList.get(i);
/*
* create a textView
*/

final TextView text = new TextView(getApplication());
text.setTag(id);
text.setText(ParameterList.get(i));
text.setTextColor(Color.RED);
text.setTextSize(20);
text.setGravity(Gravity.CENTER);
ln.addView(text);
/*
* click on text items change item text Color
*/
text.setOnClickListener(new OnClickListener() {

@Override
public void onClick(View v) {

In this tutorial Explain how to create CheckBox in android. a checkBox very usefull widgets in android, and the CheckBox class is subclass of compoundButton class.

CheckBox methods how to call , we will explain below.

public boolean isChecked()

Returns true if it is checked otherwise false.

public void setChecked(boolean status)

Changes the state of the CheckBox.

activtiy_main.xml

.............................................................................................................................................................

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

});

// Declare the in and out animations and initialize them
Animation in = AnimationUtils.loadAnimation(this,android.R.anim.slide_in_left);
Animation out = AnimationUtils.loadAnimation(this,android.R.anim.slide_out_right);

// set the animation type of textSwitcher
TxtSwitcher.setInAnimation(in);
TxtSwitcher.setOutAnimation(out);

// ClickListener for NEXT button
// When clicked on Button TextSwitcher will switch between texts
// The current Text will go OUT and next text will come in with specified animation
Nextbtn.setOnClickListener(new View.OnClickListener() {

public void onClick(View v) {
// TODO Auto-generated method stub
