如何解决从图库中选择图像时如何裁剪图像？
请参阅本教程-> http://www.androidcoding.in/2018/02/17/android-upload-image-using-retrofit-library-part2/
本教程仅从画廊中选择图像不裁剪
实际上，我的想法是从带有裁剪功能的画廊中选择一张图片，然后使用您可以在我的代码中找到的翻新帖子上传该图片->除裁剪功能外，这已实现
只有左边是裁剪。.我需要帮助
以下是我的代码->
class EditProfile:AppCompatActivity (){
private val IMAGE = 100
var bitmap: Bitmap? = null
var profile:ImageView?=null
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.editprofile)
var mActionBarToolbar = findViewById<androidx.appcompat.widget.Toolbar>(R.id.toolbartable);
setSupportActionBar(mActionBarToolbar);
// add back arrow to toolbar
if (getSupportActionBar() != null){
getSupportActionBar()?.setDisplayHomeAsUpEnabled(true);
getSupportActionBar()?.setDisplayShowHomeEnabled(true);
getSupportActionBar()?.setHomeAsUpIndicator(R.drawable.ic_keyboard_arrow_left_black_24dp);
getSupportActionBar()?.setDisplayShowTitleEnabled(false);
//supportActionBar?.setTitle("Tables")
// getSupportActionBar()?.setTitle((Html.fromHtml("<font color=\"#FFFFFF\">" + getString(R.string.Myaccount) + "</font>")));
}
val myCalendar: Calendar = Calendar.getInstance()
val edittext1 = findViewById(R.id.dob) as EditText
val date =
OnDateSetListener { view,year,monthOfYear,dayOfMonth -> // TODO Auto-generated method stub
myCalendar.set(Calendar.YEAR,year)
myCalendar.set(Calendar.MONTH,monthOfYear)
myCalendar.set(Calendar.DAY_OF_MONTH,dayOfMonth)
val myFormat = "dd-MM-yyyy" //In which you need put here
val sdf = SimpleDateFormat(myFormat,Locale.US)
edittext1.setText(sdf.format(myCalendar.getTime())) }
edittext1.setOnClickListener(object : View.OnClickListener {
override fun onClick(v: View?) {
// TODO Auto-generated method stub
DatePickerDialog(
this@EditProfile,date,myCalendar
.get(Calendar.YEAR),myCalendar.get(Calendar.MONTH),myCalendar.get(Calendar.DAY_OF_MONTH)
).show()
}
})
val edit= edittext1.text
profile = findViewById<View>(R.id.profilepic) as ImageView

RetrofitClient.instance.fetchUser(token)

真的需要帮助，谢谢！
解决方法
使其易于使用 它具有文件选择器，因此您也不必实现它。
// start picker to get image for cropping and then use the image in cropping activity
CropImage.activity()
.setGuidelines(CropImageView.Guidelines.ON)
.start(this);
