android: stretch image in imageview to fit screen

问题

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();

imgView.setMinimumWidth(width);
imgView.setMinimumHeight(height);

imgView.setMaxWidth(width);
imgView.setMaxHeight(height);

Any other ideas?

回答1:

use imgview.setScaleType(ScaleType.FIT_XY);

回答2:

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.

回答3:

use this:

ImageView.setAdjustViewBounds(true);

回答4:

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"/>

回答5:

The accepted answer is perfect, however if you want to do it from xml, you can use android:scaleType="fitXY"

回答6:

I Have used this android:scaleType="fitXY" code in Xml file.

回答7:

just change your ImageView height and width to wrap_content and use

exampleImage.setScaleType(ImageView.ScaleType.FIT_XY);

in your code.

回答8:

Trying using :

imageview.setFitToScreen(true);
imageview.setScaleType(ScaleType.FIT_CENTER);

This will fit your imageview to the screen with the correct ratio.
