Question

I have two Activities first activity has the dynamic image view and on click i am calling the second activity where camera in invoked to capture a image, now i am able to invoke camera and capture a image but how would i pass that image to the previous activity and set to the image view.

String fileName = "testphoto.jpg";
    ContentValues values = new ContentValues();
    values.put(MediaStore.Images.Media.TITLE, fileName);
    values.put(MediaStore.Images.Media.DESCRIPTION,
            "Image capture by camera");
    values.put(MediaStore.Images.Media.MIME_TYPE, "image/jpeg");
    imageUri = getContentResolver().insert(
            MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values);
    Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
    intent.putExtra(MediaStore.EXTRA_OUTPUT, imageUri);
    intent.putExtra(MediaStore.EXTRA_VIDEO_QUALITY, 1);
    startActivityForResult(intent, IMAGE_CAPTURE);

Answer 1

Finally I achieve using two activities with the help of startActivityForResult.

check below piece code, hope its helpful you:

main.xml

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



    <Button
        android:id="@+id/button1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentLeft="true"
        android:layout_alignParentTop="true"
        android:layout_marginLeft="57dp"
        android:layout_marginTop="84dp"
        android:text="Button" />


     <ImageView
        android:id="@+id/image"
        android:layout_width="100dp"
        android:layout_height="100dp"
        android:layout_centerHorizontal="true"
        android:layout_centerVertical="true"
         />

</RelativeLayout>

FirstActivity.java

It will open second activity with startActivityResult

package com.example.demo_cameraintent;

import java.io.File;

import android.app.Activity;
import android.content.Intent;
import android.graphics.Bitmap;
import android.graphics.BitmapFactory;
import android.os.Bundle;
import android.os.Environment;
import android.util.Log;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.ImageView;
import android.widget.ImageView.ScaleType;

public class MainActivity extends Activity {
    ImageView image;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        image=(ImageView)findViewById(R.id.image);

        String extStorageDirectory = Environment.getExternalStorageDirectory()
                + "/testing";

      File xmlDirectory = new File(extStorageDirectory);
        if (!xmlDirectory.exists())
            xmlDirectory.mkdirs();

        Button btn=(Button)findViewById(R.id.button1);

        btn.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                Intent i = new Intent(MainActivity.this, SecondActivity.class);
                startActivityForResult(i, 1);

            }
        });
    }

    protected void onActivityResult(int requestCode, int resultCode, Intent data) {

        if (requestCode == 1) {

             if(resultCode == RESULT_OK){

              String result=data.getStringExtra("result");
              Log.d("*****************", "inside onactivityresult in main activity="+result);

            Bitmap bitmap = BitmapFactory.decodeFile(result);
            image.setImageBitmap(bitmap);
            image.setScaleType(ScaleType.FIT_XY);

        }

        if (resultCode == RESULT_CANCELED) {



             //Write your code on no result return 

        }
        }//onAcrivityResult


    }
}

SecondActivity.java

Here when its called it will directly open cameraIntent and within onActivityResult it will return back to Firstactivity with your output

package com.example.demo_cameraintent;

import java.io.File;

import android.app.Activity;
import android.content.Intent;
import android.net.Uri;
import android.os.Bundle;
import android.os.Environment;
import android.provider.MediaStore;
import android.view.Menu;

public class SecondActivity extends Activity {
    String filepath;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        //setContentView(R.layout.main);

         filepath = Environment.getExternalStorageDirectory()+"/testing/"+"test.jpg";
        System.out.println("thumbnail path~~~~~~"+filepath);
        File file = new File(filepath);
        Uri outputFileUri = Uri.fromFile(file);


        Intent intent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
        intent.putExtra(MediaStore.EXTRA_OUTPUT, outputFileUri);
        startActivityForResult(intent, 100);


    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
            if (requestCode == 100) {

                 Intent returnIntent = new Intent();
                 returnIntent.putExtra("result",filepath);
                 setResult(RESULT_OK,returnIntent);     
                 finish();
        }


    }



}
