從圖庫中選擇圖像時如何裁剪圖像？

Question

我指的是本教程 --> http://www.androidcoding.in/2018/02/17/android-upload-image-using-retrofit-library-part2/

本教程僅從圖庫中選擇圖像而不裁剪它

實際上，我的想法是使用 select 來自畫廊的具有裁剪功能的圖像，並使用 retrofit 帖子上傳該圖像，您可以在我的代碼中找到它--> 除了裁剪功能之外，這是實現的

只剩下裁剪..我需要幫助

到目前為止，以下是我的代碼 -->

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

                this@EditProfile, date, myCalendar
                    .get(Calendar.YEAR), myCalendar.get(Calendar.MONTH),

真的需要幫助提前致謝

為了便於使用它有文件選擇器，所以你不必也實現它。

// start picker to get image for cropping and then use the image in cropping activity
CropImage.activity()
  .setGuidelines(CropImageView.Guidelines.ON)
  .start(this);
