I am trying to convert an XML Layout to an JPEG image. (This can be
helpful in many ways: for example - using in-built rendering engine's
capability to center crop an image by having an ImageView in an
AbsoluteLayout as shown below.)
<?xml version="1.0" encoding="utf-8"?>
<AbsoluteLayout
xmlns:android="http://schemas.android.com/apk/res/android";
android:id="@+id/al44"
android:orientation="vertical"
android:layout_width="320px"
android:layout_height="480px">
<ImageView
android:id="@+id/image1"
android:layout_width="320px"
android:layout_height="480px"
android:layout_x="0px"
android:layout_y="0px"
android:scaleType="centerCrop"
android:src="@drawable/centred"
/>
</AbsoluteLayout>
I use the following code to do this, but all I get is a blank image.
Any suggestions?
Bitmap targetBitmap = Bitmap.createBitmap(320, 480,
Bitmap.Config.RGB_565);
Canvas drawingCanvas = new Canvas(targetBitmap);
AbsoluteLayout al = (AbsoluteLayout)View.inflate(this,
R.layout.my_image, null);
al.draw(drawingCanvas);
FileOutputStream fos = this.openFileOutput("result.jpg",
MODE_WORLD_READABLE);
targetBitmap.compress(Bitmap.CompressFormat.JPEG, 75, fos);
fos.flush();
fos.close();
