  1. POTaking a "screenshot" of a specific layout in Android
    text
    copied!<p>I have two main issues which are closely linked. I am looking at these problems from a programmatic point of view.</p> <p><strike> (1) - I wish to take a screenshot of the contents of a SPECIFIC layout, i.e. a <code>ScrollView</code> nested in a <code>LinearLayout</code>.</strike></p> <p>(2) - As the <code>ScrollView</code> has content that spills out of the screen (hence scrolling made possible), how can I ensure that the screenshot includes the elements that are not visible on the screen?</p> <p>This is the current block of code I use. It does the job of taking a screenshot but only for the entire screen. <strike>This is even though <code>R.id.boss</code> is the ID of the <code>ScrollView</code> and not the main <code>LinearLayout</code>.</strike></p> <pre><code>View view = findViewById(R.id.boss); View v = view.getRootView();// this does not seem to make a difference v.setDrawingCacheEnabled(true); v.measure(MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED), MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED)); v.layout(0, 0, v.getMeasuredWidth(), v.getMeasuredHeight()); v.buildDrawingCache(true); Bitmap b = Bitmap.createBitmap(u.getDrawingCache()); v.setDrawingCacheEnabled(false); </code></pre> <p>Thanks in advance.</p> <p><strong>EDIT:</strong></p> <p>I've made a few mistakes. I used <code>R.id.boss</code> which is the wrong resource. I am now able to take a screenshot of the scrollview alone, less the out-of-screen parts.</p> <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt; &lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/boss" android:layout_width="fill_parent" android:layout_height="fill_parent" android:layout_gravity="top" android:orientation="vertical" &gt;
