How can I make an image transparent on Android?

Solution 1:

Try this:

ImageView myImage = (ImageView) findViewById(R.id.myImage);
myImage.setAlpha(127); //value: [0-255]. Where 0 is fully transparent and 255 is fully opaque.

Note: setAlpha(int) is deprecated in favor of setAlpha(float) where 0 is fully transparent and 1 is fully opaque. Use it like: myImage.setAlpha(0.5f)

Solution 2:

android:alpha does this in XML:

<ImageView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:src="@drawable/blah"
    android:alpha=".75"/>
