Android Open album pick a picture or turn on the camera to take pictures and crop

The first thing is to open a local album to choose a picture:

Intent albumintent = new Intent (intent.action_pick);//Open the system's album Albumintent.settype ("image/*"); Startactivityforresult (Albumintent, 0x1004);

When you finish selecting the picture, write the data in Onactivityresult:

@Overrideprotected void Onactivityresult (int requestcode, int resultcode, Intent data) {        if (data==null) {if (isNull) {}else {     if (requestcode==0x1004) {//Select Picture from album Getclipphotobypickpicture (Data.getdata (), Data.getextras ());}}}

get the return data to crop the picture:

/** * Get the returned photo information * @param URI to the URI of the returned data * @param bundle */private void Getclipphotobypickpicture (Uri Uri, Bu) into the returned data Ndle bundle) {if (URI = = null) {/** * */  } else {Intent Intent = new Intent ("Com.android.camera.action.CROP"); intent.se Tdataandtype (URI, "image/*"), Intent.putextra ("crop", "true"), Intent.putextra ("Aspectx", 1);//Aspectx is the ratio of width to height, Here the square is set (aspect ratio is 1:1) Intent.putextra ("Aspecty", 1), Intent.putextra ("Outputx", 400); Outputx Outputy is a cropped picture with a wide height of Intent.putextra ("Outputy", 400); Somehow, I can't set it too large, <640intent.putextra ("scale", true); Intent.putextra (Mediastore.extra_output, URI); Intent.putextra ("Return-data", true); Intent.putextra ("OutputFormat", Bitmap.CompressFormat.JPEG.toString ()); Intent.putextra ("Nofacedetection", true); Startactivityforresult (Intent, 0x1006);}}

call the system camera to take pictures and crop:

Boolean isnull=false;//determines whether the camera return data is empty       Intent Getimagebycamera = new Intent ("Android.media.action.IMAGE_CAPTURE") ; File File = new file (environment.getexternalstoragedirectory () + "/elephant/accountimg/accountimg.jpg"); File.exists ()) {File.delete ();} Specifies that the Uri stores the photo Getimagebycamera.putextra (mediastore.extra_output,uri.fromfile (file)); isNull = true; Startactivityforresult (Getimagebycamera, 0x1005);

also write the receive data in the Onactivityresult, but at this time found that the returned data is empty, at this time have to add a judgment:

if (data==null) {if (isNull) {///when the returned data is empty and IsNull is true, the photo taken by the camera is saved as file fileimg = new file ( Environment.getexternalstoragedirectory () + "/elephant/accountimg/accountimg.jpg"); Uri Urifromimg=uri.fromfile (fileimg);//extract uri//crop image Intent Intent = new Intent ("Com.android.camera.action.CROP"); Intent.setdataandtype (urifromimg, "image/*"); Intent.putextra ("Crop", "true"); Intent.putextra ("Aspectx", 1);// The ASPECTX is a wide-height ratio, where the square is set (the aspect ratio is 1:1) Intent.putextra ("Aspecty", 1); Intent.putextra ("Outputx", 400); Outputx Outputy is a cropped picture with a wide height of Intent.putextra ("Outputy", 400); Somehow, I can't set it too large, <640intent.putextra ("scale", true); Intent.putextra (Mediastore.extra_output, urifromimg); Intent.putextra ("Return-data", true); Intent.putextra ("OutputFormat", Bitmap.CompressFormat.JPEG.toString ()); Intent.putextra ("Nofacedetection", true); No face Detectionstartactivityforresult (intent, 0x1006); LOG.D ("Logd", "Behind the URI"); isnull=false;}} else {//when Data!=null}

Also written in Onactivityresult, let the cropped picture appear on the ImageView:

if (Requestcode = = 0x1006) {//Receive cropped picture information and save to local folder bitmap Bmap = Data.getparcelableextra ("data"); Iv_show_ Img.setimagebitmap (BMAP);//The image is saved to a file FileOutputStream Foutput = null;try {File Filedir = new file ( Environment.getexternalstoragedirectory () + "/elephant/accountimg/"), if (!filedir.exists ()) {fileDir.mkdirs ();} File fileimg = new file (Filedir, "accountimg.jpg"), if (Fileimg.exists ()) {Fileimg.delete ();} Foutput = new FileOutputStream (fileimg); Bmap.compress (Bitmap.CompressFormat.JPEG, foutput); Compress picture} catch (FileNotFoundException e) {e.printstacktrace ();} finally {if (null! = Foutput) {try {foutput.close ()} CATC H (IOException e) {e.printstacktrace ();}}}}
