android: stretch image in imageview to fit screen
I have an imageview
that has its height and width set to fill_parent
with a linearlayout
that has the same values set. So I suppose this should set my images to fit the screen. But it only fits like 80% (margin top and bottom in landscape mode).
I've tried the following code without success:
Display display = getWindowManager().getDefaultDisplay();
int width = display.getWidth();
int height = display.getHeight();
im开发者_运维知识库gView.setMinimumWidth(width);
imgView.setMinimumHeight(height);
imgView.setMaxWidth(width);
imgView.setMaxHeight(height);
Any other ideas?
to change pro-grammatically use :
imgview.setScaleType(ScaleType.FIT_XY);
OR
to change from xml use:
android:scaleType="fitXY"
Give in the xml file of your layout android:scaleType="fitXY"
P.S : this applies to when the image is set with android:src="..."
rather than android:background="..."
as backgrounds are set by default to stretch and fit to the View.
use this:
ImageView.setAdjustViewBounds(true);
if you use android:scaleType="fitXY"
then you must specify
android:layout_width="75dp"
and android:layout_height="75dp"
if use wrap_content it will not stretch to what you need
<ImageView
android:layout_width="75dp"
android:layout_height="75dp"
android:id="@+id/listItemNoteImage"
android:src="@drawable/MyImage"
android:layout_alignParentTop="true"
android:layout_alignParentStart="true"
android:layout_marginStart="12dp"
android:scaleType="fitXY"/>
The accepted answer is perfect, however if you want to do it from xml, you can use android:scaleType="fitXY"
I Have used this android:scaleType="fitXY"
code in Xml file.
just change your ImageView height and width to wrap_content and use
exampleImage.setScaleType(ImageView.ScaleType.FIT_XY);
in your code.
for XML android
android:src="@drawable/foto1"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:scaleType="centerCrop"
Maybe this is irrelevant. This how I do it on android studio.
Put this in the xml:
android:adjustViewBounds="true"
android:scaleType="centerCrop"
adjustViewBounds = will fit the image according to the ratio
scaleType = crop out all the white empty spaces
Then, set the
layout_width = match_parent
layout_height = warp_content
will become like this
Trying using :
imageview.setFitToScreen(true);
imageview.setScaleType(ScaleType.FIT_CENTER);
This will fit your imageview to the screen with the correct ratio.
