Question

i have an imageview

and i have set a bitmap on it:

package com.integrated.mpr;


import android.app.Activity;
import android.graphics.Bitmap;
import android.graphics.BitmapFactory;
import android.os.Bundle;
import android.os.Environment;
import android.widget.ImageView;
import android.widget.TextView;

public class AlternativeShow extends Activity{


    ImageView altiva;



    @Override
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        setContentView(R.layout.alternativeshow);
        File fa = new File(folder,"bmp1.png");
        Bitmap bmpa = BitmapFactory.decodeFile(fa.getAbsolutePath());

        altiva.setImageBitmap(bmpa);
        }
    }
}

I want that on touching of the screen on the imageview , the image should be zoomed >>

How can I make it possible??

Answer 1

Use a WebView instead. You can load your image like this:

webview.loadUrl("file:///android_asset/image.jpg");

Of course you must have your image.jpg in your assets folder.

If you have it in your SD Card…

String imageName = "image.jpg";
webview.loadUrl("file://" + Environment.getExternalStorageDirectory() + "/newdir/" + imageName);

WebView already has zoom implemented so you don’t really need to do anything 😉

Hope it helps you.
