How to avoid multiple button click at same time in android?

The standard way to avoid multiple clicks is to save the last clicked time and avoid the other button clicks within 1 second (or any time span).
Example:

// Make your activity class to implement View.OnClickListener
public class MenuPricipalScreen extends Activity implements View.OnClickListener{

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        // setup listeners.
        findViewById(R.id.imageView2).setOnClickListener(MenuPricipalScreen.this);
        findViewById(R.id.imageView3).setOnClickListener(MenuPricipalScreen.this);
        ...
     }

    .
    .
    .

    // variable to track event time
    private long mLastClickTime = 0;

    // View.OnClickListener.onClick method defination

    @Override
    public void onClick(View v) {
        // Preventing multiple clicks, using threshold of 1 second
        if (SystemClock.elapsedRealtime() - mLastClickTime < 1000) {
            return;
        }
        mLastClickTime = SystemClock.elapsedRealtime();

        // Handle button clicks
        if (v == R.id.imageView2) {
            // Do your stuff.
        } else if (v == R.id.imageView3) {
            // Do your stuff.
        }
        ...
    }

    .
    .
    .

 }
