How can i change the image source of ImageView after some time progmatically

Question

I want to update the source of image view after some time but by changing the source it will overlap with the previous one. this is the complete code of my activity class. I tried by both runnable and countdowmtimer but the problem is still

enter image description here[1]

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_image_content_pop_up);
        imageUrl=new ArrayList<>();
        for(int i=1;i<=3;i++)
        {
            imageUrl.add("https://www.gstatic.com/webp/gallery3/"+i+".png");
        }
        LinearLayoutManager layoutManager=new LinearLayoutManager(this,LinearLayoutManager.HORIZONTAL,false);
        recyclerImagevIew=(RecyclerView)findViewById(R.id.image_recycler_view);
        recyclerImagevIew.setLayoutManager(layoutManager);
        ImagePopupAdapter imagePopupAdapter =new ImagePopupAdapter(this,imageUrl);
        recyclerImagevIew.setAdapter(imagePopupAdapter);
        background_Image=(ImageView) findViewById(R.id.background_image);
        cross_sign =(TextView)findViewById(R.id.cross_button);
        cross_sign.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                finish();
            }
        });
        //  StartAsyncTask();
        // StartTimer();
        handler=new Handler();
        runnable= new Runnable() {
            @Override
            public void run() {
                if(index<imageUrl.size()) {
                    Glide.with(getApplicationContext()).load(imageUrl.get(index)).into(background_Image);
                    index++;
                    handler.postDelayed(runnable, 5000);
                }
            }
        };
        handler.postDelayed(runnable,1000);
    }
    public void StartTimer()
    {
        CountDownTimer timer = new CountDownTimer(15000, 5000) //10 second Timer
        {
            public void onTick(long l)
            {
                Glide.with(getApplicationContext()).load(imageUrl.get(index)).into(background_Image);
                index++;
            }

            @Override
            public void onFinish()
            {
                SystemClock.sleep(5000);
                handler.post(new Runnable() {
                    public void run() {
                        finish();
                    }
                });
            };
        }.start();

    }

Why u use `getApplicationContext()` instead of `this` or `YourActivity.this` , so first you have to change this and then after check the difference between getApplicationContext() and current this , `YourApplication.this` — ND1010_, Jan 18 '19 at 12:20
this refer to the runnable or countdowntimer object ,that why i used it — Hafiz Muzammil Arif, Jan 18 '19 at 12:26
But `onTick(long l)` call in mainThread so no need to pass getApplicationContest() bro — ND1010_, Jan 18 '19 at 12:28

This issue occur becaouse of Glide will cashing all image urls so you have to use diskCacheStrategy(DiskCacheStrategy.NONE) to resolve the issue. I am sure that you not get this issue during app runs very first time.

Note: Please check app in real device.

Glide.with(DemoActivity.this)
    .load(Uri.parse("file://" + imagePath))
    .diskCacheStrategy(DiskCacheStrategy.NONE)
    .skipMemoryCache(true)
    .into(mImage);

In your case

Glide.with(this)
            .load("")
            .apply(new RequestOptions()
                    .placeholder(R.drawable.ic_launcher_background)
                    .diskCacheStrategy(DiskCacheStrategy.NONE)
                    .skipMemoryCache(true))
            .into(view);

No the issue is in your index may be make index = 0 – ND1010_ Jan 18 '19 at 13:28
index is initialized with 0 and then incremented by 1 after setting image source – Hafiz Muzammil Arif Jan 18 '19 at 13:49
