I have downloaded image at run time. Now I want to set it as a background for relative layout how to it? Does it possible.

推荐答案

退房的<一个href="http://developer.android.com/reference/android/view/View.html#setBackgroundDrawable(android.graphics.drawable.Drawable)"相对=nofollow> setBackgroundDrawable ，或者<一href="http://developer.android.com/reference/android/graphics/drawable/Drawable.html#createFromPath(java.lang.String)"相对=nofollow>在绘制对象类createFromPath 。

   RelativeLayout rLayout = (RelativeLayout) findViewById (R.id.rLayout);
   Resources res = getResources(); //resource handle
   Drawable drawable = res.getDrawable(R.drawable.newImage); //new Image that was added to the res folder

    rLayout.setBackground(drawable);
