Menu
The screen displays four buttons. When a button is pressed, a media player plays a sound. The problem I'm having is implementing setClickable for all buttons at the same time.
Once a button is clicked, I want all buttons to be unclickable until the media player is finished playing the sound associated with the button click. Then I want all buttons to be set back to clickable.
The code runs fine until I enable the setClickable code--the code for buttonOne is disabled in my code sample below. The test phone locks up and tells me the application has stopped and to try again.
Unfortunately, without setClickable, the user could press any button and hear any sound before the first selected sound is finished playing.
Thank you for your time and help.

Sometimes user clicks button too fast or double time, if button performs some kind of network operation, it'll call the function multiple times. To prevent double click, you can record the last time button clicked, and compare it to threshold of desired time.
To define the click event handler for a button, add the android:onClick attribute to the <Button> element in your XML layout. The value for this attribute must be the name of the method you want to call in response to a click event. The Activity hosting the layout must then implement the corresponding method.
Here's a OnClickListener proxy that prevents successive clicks, based on qezt's answer. button. setOnClickListener(new MultiClickGuard(new View. OnClickListener() { @Override public void onClick(View v) { // do something } }, 1000)); button.
i think the property you are looking for would be setEnabled (set with boolean)
some code;
public void enableDisableButtons(Boolean state){
buttonOne.setEnabled(state);
buttonTwo.setEnabled(state);
buttonThree.setEnabled(state);
buttonFour.setEnabled(state);
}
public void freezeButtonsAndPlaySoundThenUnfreezeButtons()
{
enableDisableButtons(false); // disable buttons
MediaPlayer mp = MediaPlayer.create(getBaseContext(), asoundfilenumber);
mp.start();
mp.setOnCompletionListener(new OnCompletionListener()//listens for player to finish then releases player
{
@Override
public void onCompletion(MediaPlayer mpalmost)
{
enableDisableButtons(true); // Re-enable buttons
mpalmost.release();
}
});
}
