I’m looking to enlarge an image of imageView that is to make that effect equal to Whatsapp when receiving an image and the user clicks on the image it opens.

android

  • Do you want to do it with a single photo or do you have a grid? @Alessandrobarreto

  • I just wish I could zoom in on the image and etc. Common effect when you want to see a better image.

  • What have you done? I have a ready-made example but it searches straight from the SD card. @Alessandrobarreto

  • So at the time I had solved my problem with a third party lib! More Could you pass me your example for me one studied? Well I already know search the image both the gallery and both the user taking the photo of the app itself

  • I’ll post the main content "the cat jump"

I’ll put "the cat jump" just because the example I made is too big:

I was using a GridView to display all images but you can have a imageView normal.

grid = (GridView) findViewById(R.id.gridview);

        adapter = new GridViewAdapter(this, FilePathStrings, FileNameStrings);

        grid.setAdapter(adapter);

        grid.setOnItemClickListener(new OnItemClickListener()
        {

            @Override
            public void onItemClick(AdapterView<?> parent, View view, int position, long id)
            {

                Intent i = new Intent(MainActivity.this, ViewImage.class);

                i.putExtra("filepath", FilePathStrings);                
                i.putExtra("filename", FileNameStrings);            
                i.putExtra("position", position);

                startActivity(i);
            }

        });

Here is the Activity that will be started at the photo click :

public class ViewImage extends Activity {


    ImageView imageview;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setContentView(R.layout.view_image);

        Intent i = getIntent(); 
        int position = i.getExtras().getInt("position");

        String[] filepath = i.getStringArrayExtra("filepath");

        imageview = (ImageView) findViewById(R.id.full_image_view);     

        Bitmap bmp = BitmapFactory.decodeFile(filepath[position]);

        imageview.setImageBitmap(bmp);

    }
}

Here the full screen layout after clicking on the photo:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" >

    <ImageView
        android:id="@+id/full_image_view"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerInParent="true" />


</RelativeLayout>

This was my solution because I had a product description with an image of the same below and I needed the user to be able to see the image in larger size, I just changed the GridView for ImageView when I went to implement.

  • Thanks, I will study your code here thanks for helping. And just a doubt, what would this Filepathstrings? the image path?

  • Okay, it’s pretty simple, I just open a new Activity in the click event and step the image and actual size.
