feature: 点击选择拍照或者打开相册，选取图片进行裁剪最后设置为圆形头像。

problem: 拍好照片，点击裁剪，弹toast“无法加载此图片”。

solution: 在裁剪的class里加两行代码

intent.addflags(intent.flag_grant_read_uri_permission);

intent.addflags(intent.flag_grant_write_uri_permission);

主要代码如下：

public static final string photo_image_file_name = "fileimg.jpg";

public static final int camera_request_code = 100;

public static final int image_request_code = 101;

public static final int result_request_code = 102;

private file tempfile = null;

private uri imageuri;

//跳转相机

private void tocamera() {

file outputimage = new file(getactivity().getexternalcachedir(),

photo_image_file_name);

try {

if (outputimage.exists()) {

outputimage.delete();

}

outputimage.createnewfile();

} catch (ioexception e) {

e.printstacktrace();

}

if (build.version.sdk_int >= 24) {

imageuri = fileprovider.geturiforfile(getactivity(),

"com.liushengjie.smartbutler.fileprovider", outputimage);

} else {

imageuri = uri.fromfile(outputimage);

}

//启动相机程序

intent intent = new intent("android.media.action.image_capture");

intent.putextra(mediastore.extra_output, imageuri);

startactivityforresult(intent, camera_request_code);

dialog.dismiss();

}

//跳转相册

private void topicture() {

intent intent = new intent(intent.action_pick);

intent.settype("image/*");

startactivityforresult(intent, image_request_code);

dialog.dismiss();

}

@override

public void onactivityresult(int requestcode, int resultcode, intent data) {

if (resultcode != getactivity().result_canceled) {

switch (requestcode) {

//相机数据

case camera_request_code:

//tempfile = new file(environment.getexternalstoragedirectory(), photo_image_file_name);

//startphotozoom(uri.fromfile(tempfile));

startphotozoom(imageuri);

break;

//相册数据

case image_request_code:

startphotozoom(data.getdata());

break;

case result_request_code:

//有可能点击舍弃

if (data != null) {

//拿到图片设置

setimagetoview(data);

//删除原来的图片

if (tempfile != null) {

tempfile.delete();

}

}

break;

}

}

}

//裁剪

private void startphotozoom(uri uri) {

if (uri == null) {

l.e("uri == null");

return;

}

intent intent = new intent("com.android.camera.action.crop");

intent.setdataandtype(uri, "image/*");

intent.addflags(intent.flag_grant_read_uri_permission);

intent.addflags(intent.flag_grant_write_uri_permission);

//裁剪

intent.putextra("crop", true);

//宽高比例

intent.putextra("aspectx", 1);

intent.putextra("aspecty", 1);

//图片质量

intent.putextra("outputx", 320);

intent.putextra("outputy", 320);

//发送数据

intent.putextra("return-data", true);

startactivityforresult(intent, result_request_code);

}

//设置图片

private void setimagetoview(intent data) {

bundle bundle = data.getextras();

if (bundle != null) {

bitmap bitmap = bundle.getparcelable("data");

profile_image.setimagebitmap(bitmap);

}

}
