Hi,

I got a question about how to change to view dymaically.

I have a empty FrameLayout in my activity.

I want to do is every 10 seconds

1) Remove all the view in the layout

2) create new videoview or webview (depend on what kind of content in the array)

3) Add it to the layout

Any suggestion how i should do it to avoid memory leak or etc?

You can do something like this as follows:


 img=new ImageView(this);
        img.setLayoutParams(new inearLayout.LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT));
        img.setImageResource(R.drawable.logo);
      
 btn = (Button)findViewById(R.id.btn);
     
       btn.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View v) {
           linearLayout.removeAllViews();
            if(ll.getChildAt(0)==null)
            {
               linearLayout.addView(img);
            }
               
            }
        });

I have done this on button click, you can do the similar using thread.
