Picture Selection from Camera & Gallery

Hello Guys,
I am here after long time and today i am posting one new sample.

Today I have build simple example in which you can select either Camera or Gallery to pick up an image.For that you have to simple click on Default image and that will launch dialog to ask selection alternative Camera / Gallery.

You can choose any one of them and pick up single image form respective item index either it could be Camera or Gallery.

I will upload next sample in which you can select multiple images from Gallery and use that path.

One Major thing that i have use here and that is Copy Image to your own created Folder. It means when you Capture any image from Camera or Gallery that image will be copied and pasted into your specific /DIR and we will use that image path from target /dir.

So, You can save and safe your images in your own directory.

Now What you will learn from this post ?

• How to Capture image from camera in android ?


• How to Pick up  image from Gallery in android ?


• How to launch alert dialog for image selection either Camera & Gallery ?


• How to create folder in SD Card ?


• How to copy image at specific folder in SD Card ?


• How to create Random File name for image ?


• How to set Header & Footer fix view using Linear Layout in android ?

Let start with XML layout. (I will show only major code here)

Main.xml

?

01 02 03 04 05 06 07 08 09 10 11 12 13	<LinearLayout android:layout_width="fill_parent" android:layout_height="fill_parent" android:layout_weight="1" android:gravity="center" android:orientation="vertical" >   <ImageView android:id="@+id/user_photo" android:layout_width="fill_parent" android:layout_height="fill_parent" android:src="@drawable/user_logo" /> </LinearLayout>

<LinearLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_weight="1"
android:gravity="center"
android:orientation="vertical" >

<ImageView
android:id="@+id/user_photo"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:src="@drawable/user_logo" />
</LinearLayout> 

Image Selection Mode Camera or Gallery Dialog 

- After the selection of one of the mode you will get either Camera screen or Gallery screen , Here you have to select any single image.

- If you are not selecting any image then result should be blank.

public void Image_Picker_Dialog() {
    AlertDialog.Builder myAlertDialog = new AlertDialog.Builder(this);
    myAlertDialog.setTitle("Pictures Option");
    myAlertDialog.setMessage("Select Picture Mode");

    myAlertDialog.setPositiveButton("Gallery", new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface arg0, int arg1) {
            Utility.pictureActionIntent = new Intent(Intent.ACTION_GET_CONTENT, null);
            Utility.pictureActionIntent.setType("image/*");
            Utility.pictureActionIntent.putExtra("return-data", true);
            startActivityForResult(Utility.pictureActionIntent, Utility.GALLERY_PICTURE);
        }
    });

    myAlertDialog.setNegativeButton("Camera", new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface arg0, int arg1) {
            Utility.pictureActionIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
            startActivityForResult(Utility.pictureActionIntent, Utility.CAMERA_PICTURE);
        }
    });
    myAlertDialog.show();

}

After Selection of Image

- Yeah, Now you have select any single image and that will come with onActivityResult.
- Now do some copy & decoding task

?

01 02 03 04 05 06 07 08 09 10 11	protected void onActivityResult(int requestCode, int resultCode, Intent data) {     super.onActivityResult(requestCode, resultCode, data);     if (requestCode == Utility.GALLERY_PICTURE) {         // data contains result         // Do some task         Image_Selecting_Task(data);     } else if (requestCode == Utility.CAMERA_PICTURE) {         // Do some task         Image_Selecting_Task(data);     } }

protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (requestCode == Utility.GALLERY_PICTURE) {
        // data contains result
        // Do some task
        Image_Selecting_Task(data);
    } else if (requestCode == Utility.CAMERA_PICTURE) {
        // Do some task
        Image_Selecting_Task(data);
    }
}
