imageview

问题 So I'm trying to load and save Images into an imageView where the location of the image is chosen through a file browser. I've been working on this for several days now and I'm gonna have a stroke if I can't get it fixed. I've tried everything I can think of. Thank you in advance for helping. UPDATED : Here is my main class: public class Main extends Application { private Stage primaryStage; private BorderPane rootLayout; public Main(){} @Override public void start(Stage primaryStage) throws

问题 The GridView is already being populated by the contents of a specific folder called "MyDir". My layout gallery_fragment is split in half by two linearlayouts. The one on the left has the GridView which is already populated with the images from "MyDir". The layout on the right has an ImageView.

问题 How can I create a selectable circular ImageView like in the current Google+ app used for the profile pictures? This is what I refer to: The image above is unselected and the below is selected. I try to replicate the profile pictures 1 to 1. My work so far: loadedImage is the Bitmap which is displayed mImageView.setBackground(createStateListDrawable()); mImageView.setImageBitmap(createRoundImage(loadedImage)); The used methods: private Bitmap createRoundImage(Bitmap loadedImage) { Bitmap

问题 I figured out how to pass a String value between activites thanks to this site, however I'm having trouble passing an image. What I'm trying to to is have a user click a button that opens the gallery and allows selecting of a picture. Then I have another button that opens another activity that displays an ImageView. I want to be able to have that ImageView's image be the chosen one from the previous activity. Here is the class that has the button I'm clicking to open the gallery and retrieve

问题 I've set up an onTouch class to determine when one of my 40 buttons is pressed. The problem I am facing is determining which button was pressed. If I use: int ID = iv.getId(); When I click on button "widgetA1" I receive the following ID: 2131099684 I would like it to return the string ID "widgetA1" from:game.xml <ImageView android:layout_margin="1dip" android:id="@+id/widgetA1" android:src="@drawable/image" android:layout_width="wrap_content" android:layout_height="wrap_content"></ImageView>

问题 I'm developing an Android 2.2 application. I want to move an image from left side of the screen to the right side of the screen. How can I do that? I've read that I have to add this image to a ListView or to a GridView to setup this animation. UPDATE I've created the following files: anim/translate_right <?xml version="1.0" encoding="utf-8"?> <set xmlns:android="http://schemas.android.com/apk/res/android" android:interpolator="@android:anim/accelerate_decelerate_interpolator"> <translate
