經(jīng)過測試,國產(chǎn)手機拍照無問題，國外手機拍照后自動選裝90度了看圖：主要有Google手機和三星手機都會有這個問題

解決辦法也很簡單說下思路：

首先獲取圖片被旋轉(zhuǎn)的角度然后通過matrix.postRotate設置角度即可代碼如下：

package com.wyze.mercury.common.utils;import android.graphics.Bitmap; import android.graphics.Matrix; import android.media.ExifInterface; import android.util.Log;import java.io.IOException;/*** @author : xiayiye5* @date : 2021/4/28 17:39*/ public class CommonTools {private static final CommonTools LOCATION_TOOLS = new CommonTools();private CommonTools() {}public static CommonTools getInstance() {return LOCATION_TOOLS;}/*** 讀取照片exif信息中的旋轉(zhuǎn)角度** @param path 照片路徑* @return 角度*/public int readPictureDegree(String path) {int degree = 0;try {ExifInterface exifInterface = new ExifInterface(path);int orientation = exifInterface.getAttributeInt(ExifInterface.TAG_ORIENTATION, ExifInterface.ORIENTATION_NORMAL);switch (orientation) {case ExifInterface.ORIENTATION_ROTATE_90:degree = 90;break;case ExifInterface.ORIENTATION_ROTATE_180:degree = 180;break;case ExifInterface.ORIENTATION_ROTATE_270:degree = 270;break;default:break;}} catch (IOException e) {Log.e("exception msg", Log.getStackTraceString(e));}return degree;}public Bitmap toReturn(Bitmap img, String path) {Matrix matrix = new Matrix();/*翻轉(zhuǎn)90度*/matrix.postRotate(+readPictureDegree(path));int width = img.getWidth();int height = img.getHeight();img = Bitmap.createBitmap(img, 0, 0, width, height, matrix, true);return img;} }

調(diào)用方法：

private fun setUploadImg(rlPicture: ImageView) {imgPath.let {val screenWidth = WpkCommonUtil.getScreenWidth();val decodeFile = BitmapFactory.decodeFile(imgPath)val width = decodeFile.widthval size = width / screenWidthval newOpts = BitmapFactory.Options()newOpts.inJustDecodeBounds = false//設置縮放比例newOpts.inSampleSize = size * 2WpkLogUtil.e("打印縮放比例", "$size =")//重新讀入圖片，注意此時已經(jīng)把options.inJustDecodeBounds 設回false了val bitmap = BitmapFactory.decodeFile(imgPath, newOpts);rlPicture.setImageBitmap(CommonTools.getInstance().toReturn(bitmap, it))}

看下前后效果圖對比：

設置角度之前

設置角度之后
