大概的流程
- 动态权限管理
- 创建布局文件,这里不多说了
- 拍照的实现
2.1创建存放图片的文件夹
2.2将文件夹路径转换为uri
2.3隐式启动相机的Activity,uri作为intent的一个参数.
2.4拍照结束后,执行onActivityResult(…)获得图片 - 相册选取图片
3.1启动相册Activity
3.2选择结束后,执行onActivityResult(…)获得图片
1、动态获取权限
(1)AndroidManifest.xml添加如下权限:
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.MOUNT_UNMOUNT_FILESYSTEMS"/>
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.CAMERA" />
<activity
android:name=".UserBaseInfoActivity"
android:windowSoftInputMode="stateHidden">
<intent-filter>
<action android:name="androd.media.action.IMAGE_CAPTURE"/>
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
(2)通过代码动态获取权限:
//判断android版本号,弹出申请权限
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
showConfirmAppPermissions();
//添加以下代码,否则Android7.0以后调用相机时会出现闪退的问题
StrictMode.VmPolicy.Builder builder = new StrictMode.VmPolicy.Builder();
StrictMode.setVmPolicy(builder.build());
}
// 7.0动态申请权限
public void showConfirmAppPermissions() {
if (ContextCompat.checkSelfPermission(this,
Manifest.permission.WRITE_EXTERNAL_STORAGE) !=
PackageManager.PERMISSION_GRANTED) {
if (ActivityCompat.shouldShowRequestPermissionRationale(this,
Manifest.permission.WRITE_EXTERNAL_STORAGE)) {
} else {
ActivityCompat.requestPermissions(this,
new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE,
Manifest.permission.READ_EXTERNAL_STORAGE, Manifest.permission.CAMERA}, 1);
}
}
}
2、布局文件xml的代码如下:

特别注意:个别品牌(例如,小米,小米,小米)的手机会出现拍照或者选择图片之后,头像的显示方向不对,一般是旋转了90度!!!因为他们本身在保存图片的时候,已经旋转了90度了。如果我们能拿到那个旋转值,就可以进行图片旋转来达到我们的目的了。
解决方案:
(将输入流InputStream转换为Bitmap后,那个旋转值就获取不到了)
1、先将输入流转换为byte[]数组,然后保存为File对象到本地。
2、通过文件路径来获取旋转值。
3、通过旋转值来进行图片旋转。
代码如下:
/** * 根据Uri来获取图片旋转后的Bitmap对象 * @param imgUri * @return */ private Bitmap rotaingImageViewBaseOfImageUri(Uri imgUri) { //该uri就是照片文件夹对应的uri try { byte[] bytes = PublicMethodUtil.toByteArray(getContentResolver().openInputStream(imgUri)); //保存文件 PublicMethodUtil.createFileWithByte(bytes); //获取旋转角度 int degree = PublicMethodUtil.readPictureDegree(avatarImagePath); bitmap = PublicMethodUtil.Bytes2Bimap(bytes); bitmap = PublicMethodUtil.rotaingImageView(degree, bitmap); return bitmap; } catch (IOException e) { e.printStackTrace(); } return null; }
其中,调用的其他方法为:
/** * 读取照片旋转角度 * * @param path 照片路径 * @return 角度 */ public static 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; } } catch (IOException e) { e.printStackTrace(); } return degree; } /** * 旋转图片 * @param angle 旋转角度 * @param bitmap 被旋转的对象 * @return */ public static Bitmap rotaingImageView(int angle, Bitmap bitmap) { Bitmap returnBm = null; // 根据旋转角度,生成旋转矩阵 Matrix matrix = new Matrix(); matrix.postRotate(angle); try { // 将原始图片按照旋转矩阵进行旋转,并得到新的图片 returnBm = Bitmap.createBitmap(bitmap, 0, 0, bitmap.getWidth(), bitmap.getHeight(), matrix, true); } catch (OutOfMemoryError e) { } if (returnBm == null) { returnBm = bitmap; } if (bitmap != returnBm) { bitmap.recycle(); } return returnBm; } /** * InputStream转换为byte[]数组 * @param input * @return * @throws IOException */ public static byte[] toByteArray(InputStream input) throws IOException { ByteArrayOutputStream output = new ByteArrayOutputStream(); byte[] buffer = new byte[4096]; int n = 0; while (-1 != (n = input.read(buffer))) { output.write(buffer, 0, n); } return output.toByteArray(); } /** * byte[]数组转换为Bitmap对象 * @param b * @return */ public static Bitmap Bytes2Bimap(byte[] b) { if (b.length != 0) { return BitmapFactory.decodeByteArray(b, 0, b.length); } else { return null; } } /** * 根据byte数组生成文件 * * @param bytes * 生成文件用到的byte数组 */ public static void createFileWithByte(byte[] bytes) { // TODO Auto-generated method stub /** * 创建File对象,其中包含文件所在的目录以及文件的命名 */ File file = new File(UserBaseInfo.userImageDirectory + "/" + UserBaseInfo.userAvatarImageName); // 创建FileOutputStream对象 FileOutputStream outputStream = null; // 创建BufferedOutputStream对象 BufferedOutputStream bufferedOutputStream = null; try { // 如果文件存在则删除 if (file.exists()) { file.delete(); } // 在文件系统中根据路径创建一个新的空文件 file.createNewFile(); // 获取FileOutputStream对象 outputStream = new FileOutputStream(file); // 获取BufferedOutputStream对象 bufferedOutputStream = new BufferedOutputStream(outputStream); // 往文件所在的缓冲输出流中写byte数据 bufferedOutputStream.write(bytes); // 刷出缓冲输出流,该步很关键,要是不执行flush()方法,那么文件的内容是空的。 bufferedOutputStream.flush(); } catch (Exception e) { // 打印异常信息 e.printStackTrace(); } finally { // 关闭创建的流对象 if (outputStream != null) { try { outputStream.close(); } catch (IOException e) { e.printStackTrace(); } } if (bufferedOutputStream != null) { try { bufferedOutputStream.close(); } catch (Exception e2) { e2.printStackTrace(); } } } }
