How can I place camera image instead of drawable image?

Question

im just new in programming. i just want my capture image to be placed instead of the drawable image in second activity. I need help for the imagePath.. codes below

MainActivity

    Button btn_cam = (Button) findViewById(R.id.btn_cam);
    btn_cam.setOnClickListener(new View.OnClickListener() {
        public void onClick(View v) {
            Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
            file = new File(MainActivity.this.getExternalCacheDir(),
                    String.valueOf(System.currentTimeMillis()) + ".jpg");
            fileUri = Uri.fromFile(file);
            intent.putExtra(MediaStore.EXTRA_OUTPUT, fileUri);
            MainActivity.this.startActivityForResult(intent, CAMERA_PIC_REQUEST);

        }
    });                                                                     }                                                                       
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (requestCode == CAMERA_PIC_REQUEST && resultCode == RESULT_OK) { 
            fileUri = data.getData();
            Intent cam = new Intent(this, MainCam.class);
            cam.putExtra("flostic", fileUri.toString());
            startActivity(cam);
            this.finish();
        }

Second Activity

            BitmapFactory.Options options = new BitmapFactory.Options();
            options.inPreferredConfig = Bitmap.Config.ARGB_8888;
            Bitmap bitmap = BitmapFactory.decodeFile(image_path, options);
            view.setImageBitmap(bitmap);

        }

Answer 1

Based on your comment, you want to get image path in second activity. Here is the crucial line for that.

String image_path = getIntent().getStringExtra("flostic");

Below is the full code.

First activity:

Button btnCam = (Button) findViewById(R.id.btn_cam);
btnCam.setOnClickListener(new View.OnClickListener() {
    public void onClick(View v) {
        File file = new File(Environment.getExternalStorageDirectory(),
                String.valueOf(System.currentTimeMillis()) + ".jpg");
        Uri fileUri = Uri.fromFile(file);

        Intent i = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
        i.putExtra(MediaStore.EXTRA_OUTPUT, fileUri);
        startActivityForResult(i, CAMERA_PIC_REQUEST);
    }
});                                                                             

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

    if(requestCode == CAMERA_PIC_REQUEST && resultCode == RESULT_OK) { 
        Intent cam = new Intent(this, MainCam.class);
        cam.putExtra("flostic", data.getDate().toString());
        startActivity(cam);
        finish();
    }
}

Second Activity:

@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.your_layout):

    ImageView view = (ImageView) findView(R.id.your_image_view);

    Intent i = getIntent();
    String imagePath = i.getStringExtra("flostic");

    BitmapFactory.Options options = new BitmapFactory.Options();
    options.inPreferredConfig = Bitmap.Config.ARGB_8888;
    Bitmap bitmap = BitmapFactory.decodeFile(imagePath, options);

    view.setImageBitmap(bitmap);
}

Answer 2

First add these permissions in manifest

<uses-permission android:name="android.permission.CAMERA" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

If your android version is greater than lolipop then add run time permission to you app. See Documentation here

MainActivity

Put onClickListener() to your camera button

 btn_cam.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {

            Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
            startActivityForResult(intent, 1);
        }
    });

And then in onActivityResult() get image path from selected image URI like this

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

    Uri uri=data.getData();
    switch (requestCode){


        case 1:
            if (resultCode==RESULT_OK){

                String path=getRealPathFromURI(uri);

                Toast.makeText(this, ""+path, Toast.LENGTH_SHORT).show();

                Intent intent=new Intent(this,SecondActivity.class);
                intent.putExtra("imagepath",path);
                startActivity(intent);
            }
    }
}

Include getRealPathFromURI() method which return path of image taken via camera. Send the image path to second activity using intent.putExtra().

   public String getRealPathFromURI(Uri uri) {
    String[] projection = { MediaStore.Images.Media.DATA };
    @SuppressWarnings("deprecation")
    Cursor cursor = managedQuery(uri, projection, null, null, null);
    int column_index = cursor
            .getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
    cursor.moveToFirst();
    return cursor.getString(column_index);
}

This code is for SecondActivity

And then in your second activity get data(image path) from first activity and store it in string variable and create bitmap from that image path and set bitmap image to your imageview

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

    String imagepath=getIntent().getExtras().getString("imagepath");


    File image_path=new File(imagepath);
    if (image_path.exists()){

        Bitmap imageBitmap = BitmapFactory.decodeFile(image_path.getAbsolutePath());

        ImageView imageView = (ImageView) findViewById(R.id.imageselect);

        imageView.setImageBitmap(imageBitmap);
    }

} }

This is how you can display camera image in second activity taken in first activity
