部分重要代码：

//照相
private void startCamera() {camera.takePicture(null, null, new Camera.PictureCallback() {@Override
    public void onPictureTaken(byte[] bytes, Camera camera) {//照片数据，byte数据的形式
        //拍照出来的相片
        BitmapFactory.Options options=new BitmapFactory.Options();options.outHeight=surfaceView.getHeight();options.outWidth=surfaceView.getWidth();Bitmap bitmap = BitmapFactory.decodeByteArray(bytes, 0, bytes.length,options);if(bitmap!=null){//以下3行代码为将横向照片变为竖向并设置尺寸为surfaceView的尺寸，，，
            Matrix matrix = new Matrix();matrix.setRotate(90);int i = surfaceView.getWidth() / bitmap.getWidth();int j = surfaceView.getHeight() / bitmap.getHeight();if(i>0){i++;}if(j>0){j++;}matrix.setScale(i,j);bitmap = Bitmap.createBitmap(bitmap, 0, 0,bitmap.getWidth() , bitmap.getHeight(), matrix, true);bitmap = Bitmap.createBitmap(bitmap, 0, 0,surfaceView.getWidth() , surfaceView.getHeight(), null, true);noWater_img.setImageBitmap(bitmap);//没有处理的相片,如需要可保存
            Bitmap textBitmap = BitmapUtils.getInstance().createWaterTextBitmap(MainActivity.this, bitmap, "文字", 45);Bitmap resource = BitmapFactory.decodeResource(getResources(), R.drawable.sun);//先将图片转成bitmap
            int left = weather_img.getLeft();int top = weather_img.getTop();Bitmap waterImgBitmap = BitmapUtils.getInstance().createWaterImgBitmap(MainActivity.this,textBitmap, resource,left ,top);water_img.setImageBitmap(waterImgBitmap);}else {camera.stopPreview();camera.release();}}
});
}
