问题
I have a FrameLayout that consist some Image views & one EditText. I am saving this layout as an image in the memory (external). First time when I set the images in imageviews everything goes fine i.e. the exact image is being saved (same as displaying on screen) but when after saving first time if I change any thing (text, image) it displays correctly on screen but in saved image it displays earlier image (first image).
XML of Layout:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<FrameLayout
android:id="@+id/imageWithoutFrame"
android:layout_height="match_parent"
android:layout_width="match_parent"
android:layout_centerInParent="true" >
<ImageView
android:id="@+id/withoutFrame_background"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:src="@drawable/background" />
<ImageView
android:id="@+id/withoutFrame_image"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:adjustViewBounds="true"
android:layout_gravity="center" />
<EditText
android:id="@+id/withoutFrame_editableText"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal|bottom"
android:layout_marginBottom="30dip"
android:hint="Write here"
android:maxLength="60" />
</FrameLayout>
</RelativeLayout>
Code that change it in bitmap is:
Bitmap bm = null;
FrameLayout savedImage = null;
savedImage = (FrameLayout)findViewById(R.id.imageWithoutFrame);
savedImage.setDrawingCacheEnabled(true);
savedImage.buildDrawingCache();
bm = savedImage.getDrawingCache();
I used this bm for saving.
Thanks for helping.
回答1:
to overcome with this problem I destroy the drawingcache after saving the image.
savedImage.destroyDrawingCache();
