见下文code ..它可以帮助你。

see below code.. it may help you.

把这两个线路在你点击按钮。

put this two line in your button click..

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

在创建这个方法，你code ..

create this method in you 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"));


            }
        }
    }

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";
        }
    }
