Comment puis-je capturer l'image et l'enregistrer dans l'affichage de l'image dans mon activité?

voir code ci-dessous.. il peut vous aider.

mettre ce que deux lignes dans votre clic de bouton..

Intent intent = new Intent("android.media.action.IMAGE_CAPTURE");
startActivityForResult(intent, 0);

créer cette méthode dans vous code..

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

         if (requestCode == 0 && resultCode == RESULT_OK) {
            if (data != null) {

                photo = (Bitmap) data.getExtras().get("data");

                add_image.setImageBitmap(photo); /* this is image view where you want to set image*/

                Log.d("camera ---- > ", "" + data.getExtras().get("data"));


            }
        }
    }

...........................................................................................

code ci-dessous vous donnent LastImageID prises par la caméra. c'est juste un code supplémentaire que vous souhaitez trou image puis son utilisation pour vous.

........................................................................................

private String getLastImageId() {
        final String[] imageColumns = { MediaStore.Images.Media._ID,
                MediaStore.Images.Media.DATA };
        final String imageOrderBy = MediaStore.Images.Media._ID + " DESC";
        Cursor imageCursor = managedQuery(
                MediaStore.Images.Media.EXTERNAL_CONTENT_URI, imageColumns,
                null, null, imageOrderBy);
        if (imageCursor.moveToFirst()) {
            int id = imageCursor.getInt(imageCursor
                    .getColumnIndex(MediaStore.Images.Media._ID));
            String fullPath = imageCursor.getString(imageCursor
                    .getColumnIndex(MediaStore.Images.Media.DATA));

            imageCursor.close();
            return fullPath;
        } else {
            return "no path";
        }
    }

Vous pouvez créer une méthode pour capturer l'image et l'appeler dans le onClickListener de votre bouton, comme ceci:

   public void takePicture(View view){

    try{
    Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
    startActivityForResult(cameraIntent, CAMERA_PIC_REQUEST);
    } catch(Exception e){
        e.printStackTrace();
    }
}

Puis remplacer la méthode onActivityResult comme ceci:

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

    case CAMERA_PIC_REQUEST:

    String path=null;
            try{
                Bitmap thumbnail = (Bitmap) data.getExtras().get("data"); 
                thumbnail = Bitmap.createScaledBitmap(thumbnail,yourDesiredImageWidth, yourDesiredImageHeight, true);
                ImageView imageView = (ImageView) findViewById(R.id.yourImageView);  
                image.setImageBitmap(thumbnail);
                break;
            }catch(Exception ee){
                ee.printStackTrace();
            }
        }
    }

poing vous avez besoin manifeste de le faire

après en mainactivity.java cela

public class MainActivity extends Activity {
Button button;
ImageView photo;
static final int Cam_Request = 1;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
button = (Button)findViewById(R.id.btnPhoto);
photo = (ImageView)findViewById(R.id.ivPhoto);
button.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent camera_intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
File file = getFile();
camera_intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(file));
startActivityForResult(camera_intent, Cam_Request);
}
});
}
private File getFile ()
{
File folder = new File("sdcard/camera_app");
if(!folder.exists())
{
folder.mkdir();
}
File image = new File(folder,"image.jpg");
return image;
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
String path = "sdcard/camera_app/image.jpg";
photo.setImageDrawable(Drawable.createFromPath(path));
}
}
