A display list records a series of graphics related operations and can replay them later. Display lists are usually built by recording operations on a DisplayListCanvas. Replaying the operations from a display list avoids executing application code on every frame, and is thus much more efficient.
Display lists are used internally for all views by default, and are not typically used directly. One reason to consider using a display is a custom View implementation that needs to issue a large number of drawing commands. When the view invalidates, all the drawing commands must be reissued, even if large portions of the drawing command stream stay the same frame to frame, which can become a performance bottleneck. To solve this issue, a custom View might split its content into several display lists. A display list is updated only when its content, and only its content, needs to be updated.
A text editor might for instance store each paragraph into its own display list.
Thus when the user inserts or removes characters, only the display list of the
affected paragraph needs to be recorded again.
Hardware acceleration
Display lists can only be replayed using a DisplayListCanvas. They are not supported in software. Always make sure that the Canvas you are using to render a display list is hardware accelerated using Canvas.isHardwareAccelerated().
Creating a display list
    ThreadedRenderer renderer = myView.getThreadedRenderer();
    if (renderer != null) {
        DisplayList displayList = renderer.createDisplayList();
        DisplayListCanvas canvas = displayList.start(width, height);
        try {
            // Draw onto the canvas
            // For instance: canvas.drawBitmap(...);
        } finally {
            displayList.end();
        }
    }

Rendering a display list on a View
    protected void onDraw(Canvas canvas) {
        if (canvas.isHardwareAccelerated()) {
            DisplayListCanvas displayListCanvas = (DisplayListCanvas) canvas;
            displayListCanvas.drawDisplayList(mDisplayList);
        }
    }

Releasing resources
This step is not mandatory but recommended if you want to release resources
held by a display list as soon as possible.
    // Mark this display list invalid, it cannot be used for drawing anymore,
    // and release resources held by this display list
    displayList.clear();

Properties
In addition, a display list offers several properties, such as setScaleX(float) or setLeft(int), that can be used to affect all the drawing commands recorded within. For instance, these properties can be used to move around a large number of images without re-issuing all the individual drawBitmap() calls.
    private void createDisplayList() {
        mDisplayList = DisplayList.create("MyDisplayList");
        DisplayListCanvas canvas = mDisplayList.start(width, height);
        try {
            for (Bitmap b : mBitmaps) {
                canvas.drawBitmap(b, 0.0f, 0.0f, null);
                canvas.translate(0.0f, b.getHeight());
            }
        } finally {
            displayList.end();
        }
    }
    protected void onDraw(Canvas canvas) {
        if (canvas.isHardwareAccelerated()) {
            DisplayListCanvas displayListCanvas = (DisplayListCanvas) canvas;
            displayListCanvas.drawDisplayList(mDisplayList);
        }
    }
    private void moveContentBy(int x) {
         // This will move all the bitmaps recorded inside the display list
         // by x pixels to the right and redraw this view. All the commands
         // recorded in createDisplayList() won't be re-issued, only onDraw()
         // will be invoked and will execute very quickly
         mDisplayList.offsetLeftAndRight(x);
         invalidate();
    }

Threading
Display lists must be created on and manipulated from the UI thread only.
