imageview

I'm trying to save an image from ImageView to devices gallery. I tried this code Code Edit: URL url = new URL(getIntent().getStringExtra("imageURL")); File f = new File(url.getPath()); addImageToGallery(f.getPath(), this); public static void addImageToGallery(final String filePath, final Context context) { ContentValues values = new ContentValues(); values.put(MediaStore.Images.Media.DATE_TAKEN, System.currentTimeMillis()); values.put(MediaStore.Images.Media.MIME_TYPE, "image/jpeg"); values.put(MediaStore.MediaColumns.DATA, filePath); context.getContentResolver().insert(MediaStore.Images.Media

I want to display an image which is saved into database in blob form on my Android. I am using ImageView as image container. Please suggest me something soon. Regards, Rahul Basically there are two options: Buffer read from BLOB wrap in InputStream so you will have InputStream which will point to BLOB data Save BLOB data to temporary file open it as FileInputStream - so in the end you'll again have stream over image data in both cases you can easily convert InputStream to bitmat data in a way: InputStream is; //stream pointing to your blob or file //... imageView=new ImageView(this); imageView

I am trying to dynamically create and then move an image in an Android activity. However, the setX() and setY() methods seem to not work correctly. It correctly sets the position of an image when it is first created and placed, but any attempt to update it results in the image being placed in the wrong spot. For instance, the image moves on the following code: ImageView image; RelativeLayout layout = (RelativeLayout)findViewById(R.id.activity_this); if(action == MotionEvent.ACTION_DOWN){ image = new ImageView(MyClass.this); layout.addView(image, width, height); image.setX(206); image.setY(206)

I want to scale an image in an ImageView in the following way. The ImageView has some dimensions Width (W) and Height (H). The image I'm putting into the image view could be smaller or bigger than WxH. I want it to scale while preserving aspect ratio to fill WxH space. It seems like the closest thing to what I want is android:scaleType="centerInside", but what I'm seeing is that if the image is smaller than WxH, it will put a small-unscaled version of that image in the center of the ImageView (like the documentation says), but I want it to scale it to "fit", while showing the entire image, and

And why the translateX and translateY is bad position on my scene ? I start on coordinate x = 100 y = 200 in real my real coordinate y = -24.8 ... why ? I need real coordinates when is my ImageView is ? primaryStage.setTitle("Title"); Group root = new Group(); Scene scene = new Scene(root, 800, 600, Color.WHITE); // border.prefHeightProperty().bind(scene.heightProperty()); //border.prefWidthProperty().bind(scene.widthProperty()); Image im = new Image("Images/universe.jpg", 800, 600, true, true); ImageView iv = new ImageView(im); Image iv1 = new Image("Images/Asteroid.png", 60, 50, false, false

So Im trying to use an onClickListener to pass an image from one activity to a new activity but I cannot figure out how to do it. How it works is the app starts with a listview where you can select an item and it opens a new activity that displays some information and an image below. I want to be able to click the image to open it in a new activity. Heres my routeDetails.java this is where the image I want to click is located package com.example.zach.listview; import android.content.Intent; import android.support.v7.app.AppCompatActivity; import android.os.Bundle; import android.view.View;
