android7.0以上打开相机、相册并显示头像（实测好用）
1 调用
private static final int CAMERA_CODE = 200;
File mFile;
Uri mImageUri;
private void openCamera() {
//创建文件用于保存图片 /storage/emulated/0/Android/data/com.ruhai.yibei/cache/images/1645415716745.jpg
mFile = new File(getExternalCacheDir(), System.currentTimeMillis() + ".jpg");
if (!mFile.exists()) {
try {
mFile.createNewFile();
} catch (IOException e) {
e.printStackTrace();
}
}
//适配7.0
if (Build.VERSION.SDK_INT < Build.VERSION_CODES.N) {
mImageUri = Uri.fromFile(mFile);
} else {
//第二个参数要和清单文件中的配置provider的authorities保持一致
mImageUri = FileProvider.getUriForFile(PersonInfoActivity.this, "com.ruhai.yibei.provider", mFile);
}
//启动相机
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
intent.putExtra(MediaStore.EXTRA_OUTPUT, mImageUri);//将拍照图片存入mImageUri
startActivityForResult(intent, CAMERA_CODE);
}
2 application便签内部配置provider，android:authorities跟getUriForFile第二个人参数一致
3 res目录下新建xml文件夹，新建file_paths.xml文件，external-cache-path标签对应文件路径getExternalCacheDir()；images对应images/,.表示不用自定义文件夹
file_path的配置跟这里相对应
ps：xml下file_paths.xml跟调用代码对应关系
4打开相册
private void openAlbum() {
Intent intent = new Intent(Intent.ACTION_PICK);
intent.setDataAndType(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, "image/*");
startActivityForResult(intent, ALBUM_CODE);
}
5显示头像
不从data拿数据，此时data数据是null,直接从上面获取mImageUri跟mFile
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == CAMERA_CODE) {
if (resultCode == RESULT_OK) {
try {
//Bitmap bitmap = BitmapFactory.decodeStream(getContentResolver()
// .openInputStream(mImageUri));
//img.setImageBitmap(bitmap);
headerImage.setImageURI(mImageUri);
//处理照相之后的结果并上传
// uploadOk(mFile);
} catch (Exception e) {
e.printStackTrace();
}
}
} else if (requestCode == ALBUM_CODE) {
//相册
if (resultCode == RESULT_OK) {
Uri imageUri = data.getData();
//处理uri,7.0以后的fileProvider 把URI 以content provider 方式 对外提供的解析方法
File file = getFileFromUri(imageUri, this);
if (file.exists()) {
headerImage.setImageURI(imageUri);
// headerImage.setImageBitmap(BitmapFactory.decodeFile(file.getName()));
}
}
}
}
