Android Select local picture and crop

This article uses the Android native selection and cropping feature. Here's the code:

public class Pickandcropactivity extends appcompatactivity implements view.onclicklistener{public static final int REQ    uest_code_pick_img = 1;    public static final int request_code_crop_img = 2;    /** * ImageView Show selected pictures and cropped images */Private ImageView img;    /** * Select the resulting picture URI */private URI MUri;        @Override protected void OnCreate (Bundle savedinstancestate) {super.oncreate (savedinstancestate);        Setcontentview (R.layout.activity_pick_and_crop);    img = (ImageView) Findviewbyid (r.id.img);                } @Override public void OnClick (View v) {switch (V.getid ()) {r.id.pick:                Startactivityforresult (Intentutils.generatepickimgintent (), request_code_pick_img);            Break Case R.id.crop:startactivityforresult (Intentutils.generatecropimgintent (MUri, Max), request_code_crop_img)                ;        Break }} @Override protected void Onactivityresult (iNT Requestcode, int resultcode, Intent data) {switch (requestcode) {case Request_code_pick_i                Mg:if (ResultCode! = RESULT_OK | | data = NULL) break;                MUri = Data.getdata ();                Contentresolver CR = This.getcontentresolver ();                    try {Bitmap Bitmap = Bitmapfactory.decodestream (Cr.openinputstream (MUri));                Img.setimagebitmap (bitmap);                } catch (FileNotFoundException e) {e.printstacktrace ();            } break;                Case Request_code_crop_img:if (ResultCode! = RESULT_OK | | data = NULL) break;                Bitmap Bmap = Data.getparcelableextra ("Data");                Img.setimagebitmap (BMAP);        Break    } super.onactivityresult (Requestcode, ResultCode, data); }}

The Intentutils class used in the middle:

public class intentutils{    /**     * Constructs a select picture of the Intent     * * @return */public    static Intent Generatepickimgintent ()    {        Intent Intent = new Intent (Intent.action_pick);        Intent.settype ("image/*");        return intent;    }    /**     * Constructs a cropped picture of intent     *     * @param uri     * @param size     * @return    */public static Intent generatecropimgintent (URI uri, int size)    {        Intent Intent = new Intent ("Com.android.camera.action.CROP ");        Muri is a picture URI that has been selected        Intent.setdataandtype (URI, "image/*");        Intent.putextra ("Crop", "true");        Cropping frame proportional        intent.putextra ("Aspectx", 1);        Intent.putextra ("Aspecty", 1);        Output picture size        Intent.putextra ("Outputx", size);        Intent.putextra ("Outputy", size);        Intent.putextra ("Return-data", true);        return intent;}    }
