我正在根据相机 Intent 拍摄图像,但问题是,即使我以纵向模式拍摄图像,它也会以横向模式出现。
为了解决这个问题,我尝试旋转图像,但收到此错误(下面提到)。
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == 1) {
int screenWidth = getResources().getDisplayMetrics().widthPixels;
int screenHeight = getResources().getDisplayMetrics().heightPixels;
File imgFile = new File(pictureImagePath);
if(imgFile.exists()){
Bitmap bm = BitmapFactory.decodeFile(imgFile.getAbsolutePath());
//Rotate image
if (getResources().getConfiguration().orientation == Configuration.ORIENTATION_PORTRAIT) {
// Notice that width and height are reversed
Bitmap scaled = ScalingUtilities.createScaledBitmap(bm, screenHeight, screenWidth, ScalingUtilities.ScalingLogic.FIT);
int w = scaled.getWidth();
int h = scaled.getHeight();
// Setting post rotate to 90
Matrix mtx = new Matrix();
mtx.postRotate(90); //Cannot resolve method 'postRotate(int)'
// Rotating Bitmap
bm = Bitmap.createBitmap(scaled, 0, 0, w, h, mtx, true);
}else{// LANDSCAPE MODE
//No need to reverse width and height
Bitmap scaled = ScalingUtilities.createScaledBitmap(bm, screenHeight, screenWidth, ScalingUtilities.ScalingLogic.FIT);
bm=scaled;
}
ImageView myImage = (ImageView) findViewById(R.id.imageView);
myImage.setImageBitmap(bm);
}
}
问题:mtx.postRotate(90);
显示:无法解析方法“postRotate(int)”
有什么帮助吗?
欢迎提出修改建议。如有任何帮助,我们将不胜感激。
最佳答案
当Bitmap.createBitmap
需要android.graphics.Matrix
时,您很可能会导入android.opengl.Matrix
。
这就是您出现编译错误的原因。
关于android - 尝试旋转图像时 : Cannot resolve method mtx. postRotate(int),我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/36110893/
