How to set a delay for setOnClickListener?

Question

The below code is for ImageButton to change its image on every click. I have created a loop to change its position, but it changed so fast.

So I need a delay function. I have tried this solution, but it did not work for me.

It says "Handler is abstract and cannot be instantiated"

The code:

public void ShapeSelectingInGame() {

    ShapeButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            ShapeButton = (ImageButton) v;
            selectShape = rand.nextInt(4);
            ShapeSaying = rand.nextInt(8);
            ColorOfShape = rand.nextInt(10);
            shapeID = "shape_" + selectShape + ShapeSaying + ColorOfShape;
            resID = getResources().getIdentifier(shapeID, "drawable", "com.example.asgames.hitit");
            ShapeButton.setImageResource(resID);
            HitTypeString.setVisibility (View.INVISIBLE);
        }
    });

    for (int i = 10; i < 10000; i += 100)
    {
        ShapeButton.setX(i);
    }
    ShapeButton.setVisibility(View.VISIBLE);
}

Use handler.postDelay

Handler handler = new Handler();
handler.postDelayed(new Runnable() {
@Override
public void run() {
    // your code here
}
}, 1000);

where 1000 means 1 second

that should not come, make sure that you are importing android.os.Handler; – Anmol317 Apr 13 '17 at 10:36

Try this and pass milliseconds as the parameter:

wait(20000);

20000 means you are waiting for 20 seconds where 20000 are milliseconds.

You have imported wrong Handler which is ava.util.logging.Handler

You should import following

import android.os.Handler;

   private Handler mHandler = new Handler();
    private Runnable mRunnable = new Runnable() {
        @Override
        public void run() {
            ShapeButton = (ImageButton) v;
            selectShape = rand.nextInt(4);
            ShapeSaying = rand.nextInt(8);
            ColorOfShape = rand.nextInt(10);
            shapeID = "shape_" + selectShape + ShapeSaying + ColorOfShape;
            resID = getResources().getIdentifier(shapeID, "drawable", "com.example.asgames.hitit");
            ShapeButton.setImageResource(resID);
            HitTypeString.setVisibility (View.INVISIBLE);
        }
    };
    private static final int DELAY = 3000;
    public void ShapeSelectingInGame() {
        ShapeButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                mHandler.postDelayed(mRunnable, DELAY);
            }
        });

        for (int i=10; i<10000;i+=100)
        {
            ShapeButton.setX(i);
        }
        ShapeButton.setVisibility(View.VISIBLE);


 }

It seems you have imported a wrong Handler class

import java.util.logging.Handler;

Change it to

import android.os.Handler;

I corrected that but the object v is not declared anymore and the Image button never appeared — Ahmad, Apr 18 '17 at 14:59

You can try this code;

  new Handler().postDelayed(
                new Runnable() {
                    public void run() {

  // your code

 }
                }, 3000); // milisecond
