由 倖福魔咒の 提交于 2019-12-07 07:58:36
问题 I've been trying for a really long time to set the bitmap so it will fit the ImageView bounds. It just doesn't work via scaleType: fitXY . My bitmap images size are lower than the ImageView 's (Saved on 100X100 pixels), I want my bitmap images to fit and stretch into the ImageView . Here's some code: <ImageView xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/imageView" android:layout_height="match_parent" android:layout_width="match_parent" android:src="@drawable

问题 I have an ImageView that is 250dp above the bottom and with translate animation i want to move it to 50dp above the bottom.

问题 I've been searching a lot, but I can't get a solution for my problem. I can't use android:rotation as I want this app to be compatible with Android API under 11 version. My problem is something similar to this: Rotating a view in Android I've done this: @Override public void draw(Canvas canvas) { canvas.save(); Drawable d = getDrawable(); canvas.rotate(-10, d.getIntrinsicWidth() / 2, d.getIntrinsicHeight() / 2); super.draw(canvas); canvas.restore(); } The ImageView is part of a RelativeLayout

由 核能气质少年 提交于 2019-12-07 00:58:31
Since I want to support tablets and smartphones without delivering a special "HD" version, I need to scale my Images depending on the resolution of the users device. This is the ImageView source that looks good on the Samsung Galaxy Nexus: <ImageView android:id="@+id/character" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentBottom="true" android:layout_centerHorizontal="true" android:background="@android:color/transparent" android:scaleType="centerCrop" android:src="@drawable/ma_un1_001" /> But it will cut the image on the nexus 7.

Tinting ImageView not working on Android 5.0. Ideas how to make it work again?

由 别来无恙 提交于 2019-12-06 20:56:37
问题 In an application I've built I noticed that the ImageViews are not tinted on devices running the new Android Lollipop.

问题 The problem I'm writing an Android app that's supposed to have a "Slideshow" feature on it. I've found this nice library, based on Picasso, that does exactly what I wanted, and it worked just fine most of the times. Problem is, sometimes my images are not loaded into the slide ImageView ... It only shows a "black canvas" as you can see on the screenshot below. I am loading the image from a local resource from my drawables.
