如何在Android中单击多个按钮以打开相机？

Question

I created camera application in Android. I have created one activity and 3 buttons and 3 image view are included in the same activity. When I have to take snap click on first button that snap will display in first image view, then when I take snap on click second button that snap will display in second image view and same as to third button.

When I run my app camera open success fully and take the snap also done but it can't display in image view same as to another buttons also. Here is my code.

Here is my Activity Code

public class Take_Snap_Page extends Activity
{
    ImageView imgPersonalSnap;
    ImageView imgAddressProofSnap;
    ImageView imgPanCardProofSnap;
    ImageView imgHideBitmap;

    Button btnPersonal ;
    Button btnAddress;
    Button btnPanCard;
    Button btnSubmitSnap;

    Bitmap bp;
    Bitmap bitmap ;

    public void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.take_snap);

        imgPersonalSnap = (ImageView)findViewById(R.id.imagesPersonnalSnap);
        imgAddressProofSnap = (ImageView)findViewById(R.id.imageAddressProofSnap);
        imgPanCardProofSnap = (ImageView)findViewById(R.id.imagePanCardproofSnap);
        imgHideBitmap = (ImageView)findViewById(R.id.imgHide);



        btnPersonal = (Button)findViewById(R.id.buttonCapture_Personal_Snap);
        btnPersonal.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                open();

                imgPersonalSnap.setImageBitmap(bitmap);

            }
        });




        btnAddress = (Button)findViewById(R.id.buttonCapture_AddressSnap);
        btnAddress.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                open();

            }
        });



        btnPanCard = (Button)findViewById(R.id.buttonCapture_PanCardSnap);
        btnPanCard.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                open();

            }
        });

    }


    public void open() {
        Intent intent = new Intent(
                android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
        startActivityForResult(intent, 0);
    }


    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) 
    {
        // TODO Auto-generated method stub
        super.onActivityResult(requestCode, resultCode, data);

        if (requestCode == 0)
        {
                if (resultCode == RESULT_OK && data !=null )
                {
                    // ... now let's see use the picture at data/
                    bp = (Bitmap) data.getExtras().get("data");
                    imgHideBitmap.setImageBitmap(bp);
                    BitmapDrawable drawable = (BitmapDrawable) imgHideBitmap.getDrawable();
                    bitmap = drawable.getBitmap();


                }
        }
    }
}

Try wit requestCode as like following.

btnAddress.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
            open(0);

        }
    });

btnAddress.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
            open(1);

        }
    });

btnPanCard.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
            open(2);

        }
    });

And

public void open(int requestCode) {
    Intent intent = new Intent(
            android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
    startActivityForResult(intent, requestCode);
}

And

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) 
{
    // TODO Auto-generated method stub
    super.onActivityResult(requestCode, resultCode, data);

    if (requestCode == 0)
    {
            if (resultCode == RESULT_OK && data !=null )
            {
                // ... now let's see use the picture at data/
                switch(requestCode){
                  case 0:
                    bp = (Bitmap) data.getExtras().get("data");
                    imgPersonalSnap.setImageBitmap(bp);
                    BitmapDrawable drawable = (BitmapDrawable) imgHideBitmap.getDrawable();
                    bitmap = drawable.getBitmap();
                    break;
                  case 1:
                    bp = (Bitmap) data.getExtras().get("data");
                    imgAddressProofSnap.setImageBitmap(bp);
                    BitmapDrawable drawable = (BitmapDrawable) imgHideBitmap.getDrawable();
                    bitmap = drawable.getBitmap();
                    break;
                  case 2:
                    bp = (Bitmap) data.getExtras().get("data");
                    imgPanCardProofSnap.setImageBitmap(bp);
                    BitmapDrawable drawable = (BitmapDrawable) imgHideBitmap.getDrawable();
                    bitmap = drawable.getBitmap();
                    break;

                }

            }
    }
}

I hope this will help you. Let me know what happend
