Display full screen image in ImageView

Display full screen image in ImageView - android

I want to display full screen image on another activity after clicking an imageview. I have 6 ImageViews in my layout and each ImageView is getting image from Parse backend. How can I display image on fetching the imagepath ?
public ImageLoader imgl;
ImageView ad1,ad2,ad3,ad4,ad5,ad6;
List<ParseObject> ob;
private ImageView[] imgs = new ImageView[5];
int k=0;
ad1=(ImageView) findViewById(R.id.ad1);
ad2=(ImageView) findViewById(R.id.ad2);
ad3=(ImageView) findViewById(R.id.ad3);
ad4=(ImageView) findViewById(R.id.ad4);
ad5=(ImageView) findViewById(R.id.ad5);
ad6=(ImageView) findViewById(R.id.ad6);
imgs[0] = ad2;
imgs[1] = ad3;
imgs[2] = ad4;
imgs[3] = ad5;
imgs[4] = ad6;
ParseQuery<ParseObject> query = new ParseQuery<ParseObject>("Adverts");
query.orderByDescending("updatedAt");
query.whereEqualTo("Status", true);
try {
ob = query.find();
System.out.println("the urls areeee "+ob);
for (ParseObject country : ob) {
ParseFile image = (ParseFile) country.get("imageFile");
imgl.DisplayImage(image.getUrl(), imgs[k]);
k=k+1;
System.out.println("the urls are"+image.getUrl());
pd.dismiss();
}
} catch (com.parse.ParseException e) {
// TODO Auto-generated catch block
pd.dismiss();
e.printStackTrace();
}
ad1.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
Intent ent= new Intent(HomeActivity.this,AdvertsActivity.class);
startActivity(ent);
}
});
}

Set click listener on your ImageView and pass your image url in argument and call method
private void viewImage(String url)
{
final Dialog nagDialog = new Dialog(ProjectDetailActivity.this,android.R.style.Theme_Translucent_NoTitleBar_Fullscreen);
nagDialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
nagDialog.setCancelable(false);
nagDialog.setContentView(R.layout.dialog_full_image);
ivPreview = (ImageView)nagDialog.findViewById(R.id.imageView1);
BitmapDrawable bmd = (BitmapDrawable)getDrawableFromUrl(url)
Bitmap bitmap = bmd.getBitmap();
ivPreview.setImageBitmap(bitmap);
nagDialog.show();
}
public Drawable getDrawableFromUrl(String imgUrl)
{
if(imgUrl == null || imgUrl.equals(""))
return null;
try
{
URL url = new URL(imgUrl);
InputStream in = url.openStream();
Drawable d = Drawable.createFromStream(in, imgUrl);
return d;
}
catch (Exception e)
{
e.printStackTrace();
}
return null;
}
use xml file
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#android:color/white"
android:layout_gravity="center" >

I Want to show this image in full page ? How to do this ? plz help me .

You can use this code for set html image and text both from textview:
This is xml code:
<TextView
android:id="#+id/txtDescription"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="5dp"
android:lineSpacingExtra="5dp"
android:padding="5dp"
android:textAppearance="#style/TextAppearance.AppCompat.Small"
android:textColor="#color/black" />
This is Java code:
public class ConditionOfUseActivity extends Activity implements Html.ImageGetter {
private TextView txtDescription;
private Drawable empty;
#Override
protected void onCreate(Bundle savedInstanceState) {
setContentView(R.layout.activity_condition_use);
txtDescription = (TextView) findViewById(R.id.txtDescription);
String source = "this is a test of <b>ImageGetter</b> it contains " +
"two images: <br/>" +
"<img src=\"http://developer.android.com/assets/images/dac_logo.png\"><br/>and<br/>" +
"<img src=\"http://developer.android.com/assets/images/icon_search.png\">";
Spanned spanned = Html.fromHtml(object.getString("content"), ConditionOfUseActivity.this, null);
txtDescription.setText(spanned);
}
#Override
public Drawable getDrawable(String s) {
LevelListDrawable d = new LevelListDrawable();
empty = getResources().getDrawable(R.drawable.splash1);
d.addLevel(0, 0, empty);
d.setBounds(0, 0, empty.getIntrinsicWidth(), empty.getIntrinsicHeight());
new LoadImage().execute(s, d);
return d;
}
class LoadImage extends AsyncTask<Object, Void, Bitmap> {
private LevelListDrawable mDrawable;
#Override
protected Bitmap doInBackground(Object... params) {
String source = (String) params[0];
mDrawable = (LevelListDrawable) params[1];
Log.d(TAG, "doInBackground " + source);
try {
InputStream is = new URL(source).openStream();
return BitmapFactory.decodeStream(is);
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (MalformedURLException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
return null;
}
#Override
protected void onPostExecute(Bitmap bitmap) {
if (bitmap != null) {
BitmapDrawable d = new BitmapDrawable(bitmap);
mDrawable.addLevel(1, 1, d);
//mDrawable.setBounds(0, 0, bitmap.getWidth(), bitmap.getHeight());
mDrawable.setBounds(0, 0, empty.getIntrinsicWidth(), empty.getIntrinsicHeight());
mDrawable.setLevel(1);
CharSequence t = txtDescription.getText();
txtDescription.setText(t);

Exception in ImageLoader fetching images from Parse.com

I'm trying to fetch images from Parse.com in the array of ImageViews. However, the app is crashing with nullpointerException in ImageLoader class. I have 5 images in parse.com and 6 ImageViews. one ImageView has an image set in drawable folder. So 5 images get loaded dynamically from parse in array of Imageviews 1-6. HomeActivity is :

In ImageLoader class:

imageViews.put(imageView, url);
Bitmap bitmap = memoryCache.get(url);
if (bitmap != null)
imageView.setImageBitmap(bitmap);
else {
queuePhoto(url, imageView);
imageView.setImageResource(stub_id);
}
}
I'm getting nullpointer at imageView.setImageResource(stub_id);
Please help.

only reason a null pointer can appear for a placeholder is ur imageview is null...May be
you have to double check whether view is passed properly

Use below xml code instead of your xml code, it will solve your problem and if you have any problem regarding that then tell me.

Here's my code, I'm getting these JSON Array values from my database. I just want to know how to change an image's src inside a list view. Because I will only use 5 images, I decided to include these images in my assets folder instead of uploading them to the web.
Can someone give me an idea to make this possible?
Here's my XML code:
<LinearLayout
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<TextView
android:id="#+id/tvUserFullName"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textColor="#000000"
android:textSize="12dip"
android:textStyle="bold"/>
//This is the imageView where I will display the image from the assets folder
<ImageView
android:id="#+id/ivUserRating"
android:layout_width="100dip"
android:layout_height="fill_parent"
android:src="#drawable/zerostar"/>
</LinearLayout>
<TextView
android:id="#+id/tvUserEmail"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="EmailAddress#domain.com"
android:textSize="9dip"/>
<TextView
android:id="#+id/tvUserComment"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text='"This is a comment. This is a comment. This is a comment. This is a comment. This is a comment."'
android:textSize="10dip"
android:layout_margin="3dip"
android:textColor="#000000"
android:maxLength="300"/>
<TextView
android:id="#+id/tvDate"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:text="August 1, 2010"
android:textColor="#000000"
android:textSize="8dip"
android:layout_gravity="right"/>
<TextView
android:id="#+id/tvTime"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:text="08:20 PM"
android:textColor="#000000"

Use SimpleAdapter as normal, but be sure to override you "adapter"'s the setViewBinder method like:
adapter.setViewBinder(new ViewBinder() {
public boolean setViewValue(View view, Object data,
String textRepresentation) {
// Check wether it's ImageView and the data
if(view instanceof ImageView && data instanceof Bitmap){
ImageView iv = (ImageView) view;
iv.setImageBitmap((Bitmap) data);
return true;
}else
return false;
}
});
then use a getBitmap() to get the assert image
public Bitmap getBitmap( String path, int i ){
Bitmap mBitmap = null;
try {
AssetManager assetManager = getAssets();
String[] files = null;
files = assetManager.list( "smartmodel/" + path );
Log.i( "Assert List", files[1].toString() );
// Pass ur file path, here is one in assert/smartmodel/ filer
mBitmap = BitmapFactory.decodeStream( this.getAssets().open( "smartmodel/" + path + "/"+ files[i]) );
} catch (Exception e) {
e.printStackTrace();
}
return mBitmap;
}
Last, in your Simple adapter List parameter, put
map.put( "ItemImage", getBitmap( gridItemName, i ));
Your passed getBitmap(...) will be show.

check position and use like,
Bitmap bmp=null;
if(position==0){
bitmap=getBitmap("img0.png");
}else if (position==1){
bitmap=getBitmap("img1.png");
}
.
.
.
Method::
private Bitmap getBitmap(String name) throws IOException
{
AssetManager asset = getAssets();
InputStream is = asset.open(name);
Bitmap bitmap = BitmapFactory.decodeStream(is);
return bitmap;
}

Show Image View from file path?

I need to show an image by using the file name only, not from the resource id.
ImageView imgView = new ImageView(this);
imgView.setBackgroundResource(R.drawable.img1);
I have the image img1 in the drawable folder. I wish to show that image from the file.
How can I do this?

Labeeb is right about why you need to set image using path if your resources are already laying inside the resource folder ,
This kind of path is needed only when your images are stored in SD-Card .
And try the below code to set Bitmap images from a file stored inside a SD-Card .
File imgFile = new File("/sdcard/Images/test_image.jpg");
if(imgFile.exists()){
Bitmap myBitmap = BitmapFactory.decodeFile(imgFile.getAbsolutePath());
ImageView myImage = (ImageView) findViewById(R.id.imageviewTest);
myImage.setImageBitmap(myBitmap);
}
And include this permission in the manifest file:
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

I think you can use this
Bitmap bmImg = BitmapFactory.decodeFile("path of your img1");
imageView.setImageBitmap(bmImg);

You can also use:
File imgFile = new File(“filepath”);
if(imgFile.exists())
{
ImageView myImage = new ImageView(this);
myImage.setImageURI(Uri.fromFile(imgFile));
}
This does the bitmap decoding implicit for you.

All the answers are outdated. It is best to use picasso for such purposes. It has a lot of features including background image processing.
Did I mention it is super easy to use:
Picasso.with(context).load(new File(...)).into(imageView);

String path = Environment.getExternalStorageDirectory()+ "/Images/test.jpg";
File imgFile = new File(path);
if(imgFile.exists())
{
Bitmap myBitmap = BitmapFactory.decodeFile(imgFile.getAbsolutePath());
ImageView imageView=(ImageView)findViewById(R.id.imageView);
imageView.setImageBitmap(myBitmap);
}

From the official site: http://developer.android.com/training/displaying-bitmaps/load-bitmap.html
ImageView image = (ImageView) findViewById(R.id.imagePreview);
try {
image.setImageBitmap(decodeSampledBitmap(picFilename));
} catch (Exception e) {
e.printStackTrace();
}
Here the methods:
private int calculateInSampleSize(
BitmapFactory.Options options, int reqWidth, int reqHeight) {
// Raw height and width of image
final int height = options.outHeight;
final int width = options.outWidth;
int inSampleSize = 1;
if (height > reqHeight || width > reqWidth) {
final int halfHeight = height / 2;
final int halfWidth = width / 2;
// Calculate the largest inSampleSize value that is a power of 2 and keeps both
// height and width larger than the requested height and width.
while ((halfHeight / inSampleSize) > reqHeight
&& (halfWidth / inSampleSize) > reqWidth) {
inSampleSize *= 2;
}
}
return inSampleSize;
}
private Bitmap decodeSampledBitmap(String pathName,
int reqWidth, int reqHeight) {
// First decode with inJustDecodeBounds=true to check dimensions
final BitmapFactory.Options options = new BitmapFactory.Options();
options.inJustDecodeBounds = true;
BitmapFactory.decodeFile(pathName, options);
// Calculate inSampleSize
options.inSampleSize = calculateInSampleSize(options, reqWidth, reqHeight);
// Decode bitmap with inSampleSize set
options.inJustDecodeBounds = false;
return BitmapFactory.decodeFile(pathName, options);
}
//I added this to have a good approximation of the screen size:
private Bitmap decodeSampledBitmap(String pathName) {
Display display = getWindowManager().getDefaultDisplay();
Point size = new Point();
display.getSize(size);
int width = size.x;
int height = size.y;
return decodeSampledBitmap(pathName, width, height);
}

You can use:
ImageView imgView = new ImageView(this);
InputStream is = getClass().getResourceAsStream("/drawable/" + fileName);
imgView.setImageDrawable(Drawable.createFromStream(is, ""));

You may use this to access a specific folder and get particular image
public void Retrieve(String path, String Name)
{
File imageFile = new File(path+Name);
if(imageFile.exists()){
Bitmap myBitmap = BitmapFactory.decodeFile(path+Name);
myImage = (ImageView) findViewById(R.id.savedImage);
myImage.setImageBitmap(myBitmap);
Toast.makeText(SaveImage.this, myBitmap.toString(), Toast.LENGTH_LONG).show();
}
}
And then you can call it by
Retrieve(Environment.getExternalStorageDirectory().toString()+"/Aqeel/Images/","Image2.PNG");
Toast.makeText(SaveImage.this, "Saved", Toast.LENGTH_LONG).show();

public static Bitmap decodeFile(String path) {
Bitmap b = null;
File f = new File(path);
// Decode image size
BitmapFactory.Options o = new BitmapFactory.Options();
o.inJustDecodeBounds = true;
FileInputStream fis = null;
try {
fis = new FileInputStream(f);
BitmapFactory.decodeStream(fis, null, o);
fis.close();
int IMAGE_MAX_SIZE = 1024; // maximum dimension limit
int scale = 1;
if (o.outHeight > IMAGE_MAX_SIZE || o.outWidth > IMAGE_MAX_SIZE) {
scale = (int) Math.pow(2, (int) Math.round(Math.log(IMAGE_MAX_SIZE / (double) Math.max(o.outHeight, o.outWidth)) / Math.log(0.5)));
}
// Decode with inSampleSize
BitmapFactory.Options o2 = new BitmapFactory.Options();
o2.inSampleSize = scale;
fis = new FileInputStream(f);
b = BitmapFactory.decodeStream(fis, null, o2);
fis.close();
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return b;
}
public static Bitmap showBitmapFromFile(String file_path)
{
try {
File imgFile = new File(file_path);
if(imgFile.exists()){
Bitmap pic_Bitmap = decodeFile(file_path);
return pic_Bitmap;
}
} catch (Exception e) {
MyLog.e("Exception showBitmapFromFile");
return null;
}
return null;
}
if you are using image loading in List view then use Aquery concept .
https://github.com/AshishPsaini/AqueryExample
AQuery aq= new AQuery((Activity) activity, convertView);
//load image from file, down sample to target width of 250 pixels .gi
File file=new File("//pic/path/here/aaaa.jpg");
if(aq!=null)
aq.id(holder.pic_imageview).image(file, 250);

onLoadImage Full load
private void onLoadImage(final String imagePath) {
ImageSize targetSize = new ImageSize(imageView.getWidth(), imageView.getHeight()); // result Bitmap will be fit to this size
//ImageLoader imageLoader = ImageLoader.getInstance(); // Get singleto
com.nostra13.universalimageloader.core.ImageLoader imageLoader = com.nostra13.universalimageloader.core.ImageLoader.getInstance();
imageLoader.init(ImageLoaderConfiguration.createDefault(getContext()));
imageLoader.loadImage(imagePath, targetSize, new SimpleImageLoadingListener() {
#Override
public void onLoadingStarted(final String imageUri, View view) {
super.onLoadingStarted(imageUri, view);
progress2.setVisibility(View.VISIBLE);
new Handler().post(new Runnable() {
public void run() {
progress2.setColorSchemeResources(android.R.color.holo_green_light, android.R.color.holo_orange_light, android.R.color.holo_red_light);
// Picasso.with(getContext()).load(imagePath).into(imageView);
// Picasso.with(getContext()).load(imagePath) .memoryPolicy(MemoryPolicy.NO_CACHE, MemoryPolicy.NO_STORE).into(imageView);
Glide.with(getContext())
.load(imagePath)
.asBitmap()
.into(imageView);
}
});
}
#Override
public void onLoadingComplete(String imageUri, View view, Bitmap loadedImage) {
if (view == null) {
progress2.setVisibility(View.INVISIBLE);
}
// else {
Log.e("onLoadImage", "onLoadingComplete");
// progress2.setVisibility(View.INVISIBLE);
// }
// setLoagingCompileImage();
}
#Override
public void onLoadingFailed(String imageUri, View view, FailReason failReason) {
super.onLoadingFailed(imageUri, view, failReason);
if (view == null) {

}
Log.e("onLoadingFailed", imageUri);
Log.e("onLoadingFailed", failReason.toString());
}
#Override

super.onLoadingCancelled(imageUri, view);
if (view == null) {

}
Log.e("onLoadImage", "onLoadingCancelled");
}
});
}

private void showImage(ImageView img, String absolutePath) {
BitmapFactory.Options options = new BitmapFactory.Options();
options.inSampleSize = 8;

}

Most of the answers are working but no one mentioned that the high resolution image will slow down the app , In my case i used images RecyclerView which was taking 0.9 GB of device memory In Just 30 Images.
I/Choreographer: Skipped 73 frames! The application may be doing too
much work on its main thread.
The solution is Sipmle you can degrade the quality like here : Reduce resolution of Bitmap
But I use Simple way , Glide handles the rest of work
fanContext?.let {
Glide.with(it)
.load(Uri.fromFile(File(item.filePath)))
.into(viewHolder.imagePreview)
}

You can easily do this using bitmap. You can find the code below :
ImageView imageView=findViewById(R.id.imageView);
Bitmap bitMapImage= BitmapFactory.decodeFile("write path of your image");
imageView.setImageBitmap(bitMapImage);

mageView.setImageResource(R.id.img);
