Sru*_*rai 3 android image bitmap rotation matrix
我是从相机意图拍摄图像的,但问题是,即使以人像模式拍摄图像,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,但出现此错误(在下面提到)。
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);正在显示:无法解析方法'postRotate(int)'
有什么帮助吗?
随时提出修改建议。任何帮助表示赞赏。
最有可能android.opengl.Matrix在Bitmap.createBitmap需要时导入android.graphics.Matrix。
这就是为什么您有编译错误。
