First Method,
In the onCreate function,
Button button = (Button) findViewById(R.id.button1);
button.setOnClickListener(new OnClickListener()
{
public void onClick(View v)
{
ImageView iv = (ImageView) findViewById(R.id.imageview1);
iv.setVisibility(View.VISIBLE);
}
});
|
Second Method,
Import the following package,
import android.view.View.OnClickListener;
In onCreate method add the following Listener,
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
addListenerOnButton();
}
Implement the Listener,
public void addListenerOnButton() {
button = (Button) findViewById(R.id.button1);
button.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View arg0) {
Intent browserIntent =
new Intent(Intent.ACTION_VIEW, Uri.parse("http://www.vijaynetwork.com"));
startActivity(browserIntent);
}
});
|
Third Method,
<Button
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:text="@string/self_destruct"
android:onClick="displayMap" />
when a user clicks the button, the Android system calls the activity's displayMap(View) function.
And the function declaration would be,
public void displayMap(View myview)
{
//made your own code for button click
}
