How to store the image in the internal memory after clicking on it?

Question

Get multiple images which are under drawable folder and show it in grid view.

After presenting it in the grid view,when we click a particular image ,it must be stored in device internal memory. the code what I implemented is shown below

public class Example3 extends AppCompatActivity {
    String[] web = {"image1", "image2", "image3",
            "image4", "image5", "image6", "image7", 
            "image8", "image9", "image10", "image11"};

    Integer[] displayImages = {R.drawable.image1, R.drawable.image2, R.drawable.image3, 
            R.drawable.image4, R.drawable.image5, R.drawable.image6, 
            R.drawable.image7, R.drawable.image8, R.drawable.image9, R.drawable.image10, R.drawable.image11};
    GridView gridView;

    @Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.example3);

        gridView = (GridView) findViewById(R.id.gridView1);
        gridView.setAdapter(new ImageAdapter(this));

        gridView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> adapterView, View view, int position, long l) {
                Toast.makeText(Example3.this, "You Clicked at " + web[+position] + " saved Successfully", Toast.LENGTH_SHORT).show();
            }
        });
    }

    private class ImageAdapter extends BaseAdapter {

        Context context;

        public ImageAdapter(Context context) {
            this.context = context;
        }

        @Override
        public int getCount() {
            return displayImages.length;
        }

        @Override
        public Object getItem(int position) {
            return position;
        }

        @Override
        public long getItemId(int position) {
            return position;
        }

        @Override
        public View getView(int position, View view, ViewGroup viewGroup) {
            ImageView imageView = new ImageView(this.context);
            imageView.setImageResource(displayImages[position]);
            imageView.setLayoutParams(new GridView.LayoutParams(180, 150));
            return imageView;
        }
    }

}

My question is - how to store a particular image in the internal memory?

Please ask for a specific problem, and not for a general, unprecise goal — Yves Delerm, Nov 25 '16 at 09:52
What exactly are you expecting and what is the problem? You should show your code so that we can help you out. — Taufiq Rahman, Nov 25 '16 at 09:52
You can use the imageAdapter for this. You should be able to identify the selected imageview from it — Nakul Sudhakar, Nov 25 '16 at 09:57

@Override
        public View getView(int position, View view, ViewGroup viewGroup) {
            ImageView imageView = new ImageView(this.context);
            imageView.setImageResource(displayImages[position]);
            imageView.setLayoutParams(new GridView.LayoutParams(180, 150));
            //add an onClickListener for the image view here to identify the specific imageview
            return imageView;
        }

Say you have an image namely ic_launcher in your drawable. Then get a bitmap object from this image like:

Bitmap bm = BitmapFactory.decodeResource( getResources(), R.drawable.ic_launcher);

The path to SD Card can be retrieved using:

String extStorageDirectory = Environment.getExternalStorageDirectory().toString();

Then save to sdcard on grid click using:

File file = new File(extStorageDirectory, "ic_launcher.PNG");
    outStream = new FileOutputStream(file);
    bm.compress(Bitmap.CompressFormat.PNG, 100, outStream);
    outStream.flush();
    outStream.close();

Don't forget to add android.permission.WRITE_EXTERNAL_STORAGE permission.

call this method in your image click listener:

 public void addImageIntoSdcard(int position) {

    //String extStorageDirectory = Environment.getExternalStorageDirectory().toString()+"/MyImages";
    File direct = new File(Environment.getExternalStorageDirectory(),"DEMO");

    if (!direct.exists()) {
        direct.mkdirs(); //directory is created;

    }

    Bitmap bm = BitmapFactory.decodeResource( getResources(), displayImages[position]);


    File file = new File(direct, web[position] + ".jpg");
    if(file.exists()){
        Toast.makeText(Example3.this, "You Clicked at " + web [+ position] + " already exists", Toast.LENGTH_SHORT).show();

    }
    else {
        Toast.makeText(Example3.this, "You Clicked at " + web [+ position] + " saved Successfully", Toast.LENGTH_SHORT).show();

    }

    FileOutputStream outStream = null;
    try {
        outStream = new FileOutputStream(file);
    } catch (FileNotFoundException e) {
        e.printStackTrace();
    }
    bm.compress(Bitmap.CompressFormat.JPEG, 100, outStream);
    try {
        outStream.flush();
    } catch (IOException e) {
        e.printStackTrace();
    }
    try {
        outStream.close();
    } catch (IOException e) {
        e.printStackTrace();
    }


}

Make sure you have to set permission:

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