Change ImageView

I have set up an ImageView in main.xml, if I want to access it from my View class and make it visible = false, how can I do this programatically?

Thank you

    public void onCreate(Bundle savedInstanceState) {  
    super.onCreate(savedInstanceState);
    theView = new GameView(this);
    theView.setBackgroundResource(R.layout.main);
    setContentView(theView);

Suppose you have a ImageView called imageView.

Now access the imageView like

imageView=(ImageView) findViewById(R.id.your_image_view);

Now when you are trying to hide the imageView just use imageView.setVisibility(View.INVISIBLE);

Hope this will help you

ImageView myView = (ImageView) findViewById(R.id.myView);
myView.setVisibility (android.View.INVISIBLE);

Use this property in the xml of that Imageview

android:visibility="visible"

and change the visibility programatically like this on some particular event:

image.setVisibility(ImageView.GONE)

where image is the instance of that imageview received through findViewById()

First you should retrieve a link to this view object. Than set visibility property of this object to View.INVISIBLE 

ImageView imageView = (ImageView)findViewById(R.id.image_view);
imageView.setVisibility(View.INVISIBLE);

For example, in your layout xml file, there is a imageview1

<ImageView
android:id="@+id/imageview1"
android:layout_gravity="center"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
/>

in your java src,

ImageView img=(ImageView)findViewById(R.id.imageview1);
img.setVisibility(View.GONE);
img.setVisibility(View.VISIBLE);
img.setVisibility(View.INVISIBLE);

you can google the difference between View.Gone and View.VISIBLE
