1.打开系统相册
Intent intent=new Intent(Intent.ACTION_PICK, MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(intent,2);
2.回调结果裁剪图片，不需要调用裁剪的也可直接上传
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
//相册返回结果，调用系统裁剪
if (requestCode==2){
Cursor cursor=getActivity(). getContentResolver() .query(data.getData()
, new String[]{MediaStore.Images.Media.DATA}
, null, null, null);
cursor.moveToFirst();
capturPath=cursor.getString(cursor.getColumnIndex(MediaStore.Images.Media.DATA));
cursor.close();
// startPicZoom(Uri.fromFile(new File(capturPath)));
Uri uri;
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
//test.xxx.com.myapplication.fileprovider 是在清单文件配置的 android:authorities
uri = FileProvider.getUriForFile(getActivity(), "com.http.user.fileprovider", new File(capturPath));
//这里一定要和AndroidManifest.xml中配置一样android:authorities
}else {
uri = Uri.fromFile(new File(capturPath));
}
cropPhoto(uri); // 裁剪图片
}
}
3.android11对手机存储进行分区,需要在清单文件配置
<provider
android:authorities="com.http.user.fileprovider" //一定要与回调结果中的一致
android:name="androidx.core.content.FileProvider"
android:grantUriPermissions="true"
android:exported="false">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="@xml/filepaths"/>
</provider>
4.下面是调用系统相册裁剪的方法,这里我的回调标识为3
/**
* 调用系统的裁剪功能
*
* @param uri
*/
public void cropPhoto(Uri uri) {
Intent intent = new Intent("com.android.camera.action.CROP");
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
}
intent.setDataAndType(uri, "image/*");
//是否可裁剪
intent.putExtra("corp", "true");
//裁剪器高宽比
intent.putExtra("aspectY", 1);
intent.putExtra("aspectX", 1);
//设置裁剪框高宽
intent.putExtra("outputX", 150);
intent.putExtra("outputY", 150);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
uritempFile=Uri.parse("file://" + "/" + Environment.getExternalStorageDirectory().getPath()+ File.separator + "Android"+File.separator+"xx.jpg");
intent.putExtra(MediaStore.EXTRA_OUTPUT, uritempFile);
}
intent.putExtra("outputFormat", Bitmap.CompressFormat.JPEG.toString());
intent.putExtra("noFaceDetection", true);
//返回数据
intent.putExtra("return-data", true);
startActivityForResult(intent, 3);
}
5.回调结果上传
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
else if(requestCode==3){
Bundle bundle= data.getExtras();
if(bundle!=null){
File file = new File(capturPath);
new Upload(file).execute("写入上传的url");
}
}
}
以流形式上传
// 下面为异步任务类
// UploadImg.uploadFile(file,strings[0]);为上传的任务类，在异步任务类中调用
public class Upload extends AsyncTask<String,Void,String> {
File file;
public Upload(File file){
this.file = file;
}
@Override
protected String doInBackground(String... strings) {
return UploadImg.uploadFile(file,strings[0]);
}
@Override
protected void onPostExecute(String s) {
super.onPostExecute(s);
Log.d("nimabitaisha2", "onPostExecute: "+s);
if(s != null){
Log.d("shabinima", "onPostExecute: "+s);
String str = null;
String[] image = s.split("\"result\":\"");
Log.d("nimabitaisha2", "onPostExecute: "+image[0]+"-----"+image[1]);
final String[] st = image[1].split("\"\\}");
SpUtils.getInstance().setValue("head", st[0].toString());
Log.d("nimabitaisha2", "onPostExecute: "+st[0]);
Toast.makeText(getActivity(),"上传成功",Toast.LENGTH_SHORT).show();
}else{
Log.d("shabinima", "onPostExecute: "+s);
Toast.makeText(getActivity(),"更换失败",Toast.LENGTH_SHORT).show();
Glide.with(getActivity())
.load(Constants.PATH_IMG+SpUtils.getInstance().getString("head"))
.apply(RequestOptions.bitmapTransform(new CircleCrop())).into(imgHead);
}
}
}
// 上传所用的任务类
public static class UploadImg {
private static final String TAG = "uploadFile";
private static final int TIME_OUT = 10*1000; //超时时间
private static final String CHARSET = "utf-8"; //设置编码 /** * android上传文件到服务器 * @param file 需要上传的文件 * @param RequestURL 请求的rul * @return 返回响应的内容 */

if(file!=null){
/** * 当文件不为空，把文件包装并且上传 */
DataOutputStream dos = new DataOutputStream( conn.getOutputStream());
StringBuffer sb = new StringBuffer();
sb.append(PREFIX);
sb.append(BOUNDARY);
sb.append(LINE_END);
