how to convert Layout view to Bitmap excluding some components

in my layout I have a background, button and a textView, the button here serves to convert my view to bitmap and save it
I managed to do that but my png Image contains the save button as well,
I'm using this line to get the drawing from my layout :
Bitmap cache = vw.getDrawingCache();
What I want to achieve is that before getting the screen from the view , I want it to not consider my button.
Thanks in advance.

Using canvas to draw layout like this
Bitmap bitmap = Bitmap.createBitmap(layout.getWidth(), layout.getHeight(), Bitmap.Config.ARGB_8888);
Canvas canvas = new Canvas(bitmap);
layout.draw(canvas);

Have you looked at setting the component to visibility gone?
Button saveButton = (Button) findViewById(R.id.save_button);
saveButton.setVisibility(View.GONE);
Then after you get your snapshot make sure you do
saveButton.setVisibility(View.VISIBLE);
The problem with this solution is that the screenshot will still contain the gap where the button was. The view does not get redrawn before the bitmap is saved. I have tried calling invalidate() and requestLayout() with no success (which is why I found your question).
Also, another alternative is to do something like what Anand said by drawing it to a Canvas. This is useful if your view is larger than the screen. By drawing it to a Canvas you can get the entire view. By going this route, you can have a container with your background and TextView and have the button outside that container. You can then get just the view with the container. (I can't use this solution since my button is in the middle of my desired data)
View v = findViewById(R.id.my_view); // the view containing your text view
// not needed since it is outside your my_view now
// v.findViewById(R.id.save_button).setVisibility(View.GONE);
Bitmap b = Bitmap.createBitmap(v.getWidth(), v.getHeight(), Bitmap.Config.ARGB_8888);
Canvas c = new Canvas(b);
v.layout(0, 0, v.getLayoutParams().width, v.getLayoutParams().height);
v.draw(c);
// not needed since it is outside your my_view now
// v.findViewById(R.id.save_button).setVisibility(View.VISIBLE);
// your Bitmap "b" now contains the image you want

Saving Multiple Circles to Bitmap android

I need to save a number of formatted circles to a Bitmap whenever a button is pushed, and then draw those circles to the canvas. I was looking around, but had a great deal of trouble finding resources on how to save a shape I had created that was not an already created resource file. Any advice on how to go about this would be appreciated.

Say you are in your custom view, but it should work also with a OnTouchListener in any view.
Create a mutable bitmap with Bitmap.createBitmap() with the same width and height of your view
use your logic for getting information of the circles, for example you can use onTouchEvent() to get the coordinates of you finger(s)
with this information you can use Bitmap.setPixel() to save it to the bitmap
optional, onDraw() you can draw your bitmap with Canvas.drawBitmap()
In case you need to draw shapes to the bitmap you can create a new Canvas(bitmap) and draw on this canvas: the pixels will be set on the bitmap.

Draw image inside a View without subclassing

Can I draw a image inside a view without subclassing ? I have tried:
TextView texto = (TextView) viewGroup.findViewWithTag("text");
Paint p = new Paint();
p.setColor(Color.WHITE);
Bitmap b = BitmapFactory.decodeResource(getResources(), R.mipmap.ic_lanc);
Bitmap b2 = b.copy(Bitmap.Config.ARGB_8888, true);
Canvas c = new Canvas(b2);
c.drawBitmap(b, 1, 1, p);
textView.draw(c);
Someone can help me?

You cannot do that directly -- calling draw(Canvas) on a view will cause that View to perform its drawing commands into the canvas. So in your case that would draw the TextView onto the Canvas you provided (not the other way around).
If you needed to do so, you could set a subclass of drawable on the view which does custom drawing itself, and then that would draw within the View's canvas, but whatever you're trying to do here, there's likely an easier way. Without knowing more about your requirements it's impossible to say.

Drawing does not work like that. The textview's draw() method will be called by android, with a canvas instance provided by the system. When you call it yourself with a canvas that you created, the textview is going to draw itself on your canvas instance, but that has nothing to do with what appears on the screen.

Android - getDrawingCache - black screen

I've read pretty much every post on this topic, but none of them seem to help.
I'm trying to capture a screen shot of the current screen. For this I'm using getDrawingCache. Here's my code:
mRootView.get().setDrawingCacheEnabled(true);
mRootView.get().buildDrawingCache();
Bitmap screenShot = Bitmap.createBitmap(mRootView.get().getDrawingCache());
mRootView.get().setDrawingCacheEnabled(false);
The resulting bitmap is always black.
mRootView is a weak-reference to the drawer layout, which is my root view.
Here's what I've tried:
Adding a measure and layout call (although this shouldn't be needed since this code runs when a button is pressed, so the view should already be layed out).
Setting the layer type to LAYER_TYPE_NONE before calling setDrawingCacheEnabled(true)
Using a different view as the root view (for example, a ViewPager inside the DrawerLayout).
Nothing seems to work and I've run out of ideas.

You can draw your view to canvas-
pass your main layout reference to this method-
Bitmap file = save(layout);
Bitmap save(View v)
{
Bitmap b = Bitmap.createBitmap(v.getWidth(), v.getHeight(), Bitmap.Config.ARGB_8888);
Canvas c = new Canvas(b);
v.draw(c);
return b;
}

If above solution not working so just follow this link might be helpful convert view to bitmap

Tiling a Bitmap on a Canvas

I would like to create a 'graph paper' look to the Bitmap I am drawing via a Canvas, and trying to figure out the best way to do this.
I can't pass a source Bitmap containing the graph paper background to the Canvas constructor, as I am getting the Canvas in a SurfaceView via the .lockCanvas() call.
Some solutions I've tried:
I've tried implementing this solution in my SurfaceView's Thread.run(), but the issue I believe is when the BitmapDrawable is converted to a Bitmap... it loses the tiling properties.
canvas = mSurfaceHolder.lockCanvas(null);
BitmapDrawable TileMe = new BitmapDrawable(BitmapFactory.decodeResource(getResources(), R.drawable.editor_graph));
TileMe.setTileModeX(Shader.TileMode.REPEAT);
TileMe.setTileModeY(Shader.TileMode.REPEAT);
Bitmap b = TileMe.getBitmap();
canvas.drawBitmap(b, 0, 0, null);
If I use the Canvas.drawBitmap method that takes a destination RectF as a parameter, it looks like the bitmap will be tiled to fill the RectF... but how do I declare a RectF reliably that fills the entire view area?
Setting the Activities background to the desired graph paper look also doesn't work, as the bitmap/canvas layout is opaque and blocks that from being seen.
Any ideas how to achieve this?

You have two easy solutions:
Either use a BitmapDrawable, but instead of extracting the Bitmap, just call BitmapDrawable.draw(Canvas). Don't forget to set the drawable's bounds to fill your drawing area.
Create a Paint with a BitmapShader and draw a rectangle with it (this is basically what BitmapDrawable does).

I'm sure there is a way to get a tiled effect using a SurfaceView. Unfortunately, it looks like you can't use the BitmapDrawable with a canvas. So you would probably have to implement you own custom tiling method by creating your own series of Rect's on the Canvas and drawing a scaled bitmap to each one.
It honestly wouldn't be that hard. Just get the width/height of the view, and create an array of Rect's based on this data that you will draw the Bitmap to.
Alternatively, if you don't need to make modifications to the actual tiled background on the fly, just draw it as a background and draw the SurfaceView on top of it. That post you linked provided multiple solutions to tiling a BitmapDrawable that you could implement.
