Generally, you need to set a user profile even if you need a lot of user information. Generally, you can either select an image from your mobile phone or take a photo directly on your mobile phone. As follows:

In addition, you can use the dynamic screenshot function of APP Bao to create a mobile phone screenshot, which is very convenient.

The layout file is simple: Add two buttons and an imageview to display the set avatar.

The core code is as follows:

1. Select an image

1     public static void selectPhoto(Activity activity) {2         Intent intent = new Intent(Intent.ACTION_GET_CONTENT);3         intent.setType("image/jpeg");4         intent.putExtra("return-data", true);5         activity.startActivityForResult(intent, PHOTO_PICKED_WITH_DATA);6     }

2. Take and store photos

 1     public static String takePicture(Activity activity) { 2         createDirFile(Environment.getExternalStorageDirectory().getPath() + "/zhaojie/images/"); 3         Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); 4         String timeStamp = new SimpleDateFormat("yyyyMMddHHmmss").format(new Date()); 5         String path = Environment.getExternalStorageDirectory().getPath() + "/zhaojie/images/" + timeStamp + ".png"; 6         File file = createNewFile(path); 7         if (file != null) { 8             intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(file)); 9         }10         activity.startActivityForResult(intent, INTENT_REQUEST_CODE_CAMERA);11         return path;12     }

3. process the photo or selected photo and capture the Avatar. You can specify the size of the Avatar.

 1     private void cropImageUri(Uri uri, int requestCode) { 2         Intent intent = new Intent("com.android.camera.action.CROP"); 3         intent.setDataAndType(uri, "image/*"); 4         intent.putExtra("crop", "true"); 5         intent.putExtra("aspectX", 1); 6         intent.putExtra("aspectY", 1); 7         intent.putExtra("outputX", 320); 8         intent.putExtra("outputY", 320); 9         intent.putExtra("scale", true);10         intent.putExtra(MediaStore.EXTRA_OUTPUT, uri);11         intent.putExtra("return-data", true);12         intent.putExtra("outputFormat", Bitmap.CompressFormat.JPEG.toString());13         intent.putExtra("noFaceDetection", true); // no face detection14         startActivityForResult(intent, requestCode);15     }

4. The overall process is basically implemented by calling the system activity. The Code is as follows:

 1     protected void onActivityResult(int requestCode, int resultCode, Intent data) { 2         super.onActivityResult(requestCode, resultCode, data); 3         if (resultCode != RESULT_OK) 4             return; 5         Bitmap tempPhoto = null; 6         switch (requestCode) { 7             case PHOTO_PICKED_WITH_DATA: // ???????? 8                 ContentResolver cr = this.getContentResolver(); 9                 try {10                     Uri uri = data.getData();11                     cropImageUri(uri, PHOTO_CROP_DATA);12                     // tempPhoto =13                     // BitmapFactory.decodeStream(cr.openInputStream(uri));14                     // mStepPhoto.setUserPhoto(tempPhoto);15                 } catch (Exception e) {16                     e.printStackTrace();17                 }18                 break;19             case INTENT_REQUEST_CODE_CAMERA:20                 tempPhoto = BitmapFactory.decodeFile(headPath);21                 cropImageUri(Uri.fromFile(new File(headPath)), PHOTO_CROP_DATA);22                 break;23             case PHOTO_CROP_DATA:24                 tempPhoto = data.getParcelableExtra("data");25                 mHead.setImageBitmap(tempPhoto);26                 break;27         }28     }
