    text
    copied!<p>I am trying to create a button that is always on the screen.</p> <ol> <li>The button should be clickable and anything directly under the button should not be activated on a press. </li> <li>The activity or home screen running behind the button should still work, meaning the user should still be able to interact with the home screen or application. </li> <li>The soft key buttons should still work: home, back, menu, etc</li> </ol> <p>The following code does #1 and #2 but the soft key buttons no longer work:</p> <pre><code>WindowManager.LayoutParams params = new WindowManager.LayoutParams( WindowManager.LayoutParams.WRAP_CONTENT, WindowManager.LayoutParams.WRAP_CONTENT, WindowManager.LayoutParams.TYPE_SYSTEM_ALERT, WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL | WindowManager.LayoutParams.FLAG_WATCH_OUTSIDE_TOUCH, PixelFormat.TRANSLUCENT); </code></pre> <p>Changing it to this disables the overlay from clicks but #2 and #3 work:</p> <pre><code>WindowManager.LayoutParams.TYPE_SYSTEM_OVERLAY, WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL, </code></pre> <p>Finally in this example the overlay and what is directly behind it gets clicked:</p> <pre><code>WindowManager.LayoutParams.TYPE_SYSTEM_OVERLAY, WindowManager.LayoutParams.FLAG_WATCH_OUTSIDE_TOUCH, </code></pre> <p>How can I change this so that the overlay is clickable, whats directly under it is not clickable, and everything outside of the overlay works including the home buttons?</p> <p>An example application that performs all of this is Super Manager.</p> <p>UPDATE: I've found that the following allows the home button to be used, but still not the other buttons:</p> <pre><code> WindowManager.LayoutParams.TYPE_SYSTEM_ALERT | WindowManager.LayoutParams.TYPE_SYSTEM_OVERLAY, WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL | WindowManager.LayoutParams.FLAG_WATCH_OUTSIDE_TOUCH </code></pre> <p>,</p>
