Introduction
This article shows how to set visibility on buttons in Android.
Procedure
Start the Eclipse IDE.
Create a new project.
Create a MainActivity.java file.
Create an XML file with three buttons.
In the onClick function set the visibility of buttons using the setVisibility function.
For example
public
void
onClick(View v) {
b1.setVisibility(v.INVISIBLE);
b2.setVisibility(v.VISIBLE);
}
The following is the code.
MainActivity.java
package

import
android.app.Activity;
import
android.os.Bundle;
import
android.view.Menu;
import
android.view.View;
import
android.view.View.OnClickListener;
import
android.widget.Button;
import
android.widget.Toast;
public
class
MainActivity
extends
Activity {
Button b1,b2,b3;
@Override
protected
void
onCreate(Bundle savedInstanceState) {
super
.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
b1=(Button)findViewById(R.id.button1);
b2=(Button)findViewById(R.id.button2);
b3=(Button)findViewById(R.id.button3);
b1.setOnClickListener(
new
OnClickListener() {
public
void
onClick(View v) {
// TODO Auto-generated method stub
b1.setVisibility(v.INVISIBLE);
b2.setVisibility(v.VISIBLE);
Toast.makeText(getApplicationContext(),
"Button2 is visible"
,Toast.LENGTH_LONG).show();
}
});
b2.setOnClickListener(
new
OnClickListener() {
public
void
onClick(View v) {
// TODO Auto-generated method stub
b2.setVisibility(v.INVISIBLE);
b3.setVisibility(v.VISIBLE);
Toast.makeText(getApplicationContext(),
"Button3 is visible "
, Toast.LENGTH_LONG).show();
}
});
b3.setOnClickListener(
new
OnClickListener() {
public
void
onClick(View v) {
b3.setVisibility(v.INVISIBLE);
b1.setVisibility(v.VISIBLE);
Toast.makeText(getApplicationContext(),
"Button1 is visible"
, Toast.LENGTH_LONG).show();
// TODO Auto-generated method stub
}
});
}
@Override
public
boolean
onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return
true
;
}
