从画廊挑选或从相机拍摄的高质量图像

Question

I have 3 tasks:

1. Pick image from gallery
2. Capture image from camera
3. Crop image from 1 or 2.

The quality of image must be good.

Are there any solution for my problem? May be some libraries?

Answer 1

Android, by default, actually has all those you enumerated.

1. To pick an image from gallery

    Intent pickPhoto = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI); startActivityForResult(pickPhoto, FROM_GALLERY); 

2. To capture image from camera

    Intent takePicture = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); startActivityForResult(takePicture, FROM_CAMERA); 

3. To fetch the results of the intents above and the do the cropping

    @Override public void onActivityResult(int requestCode, int resultCode, Intent data) { super.onActivityResult(requestCode, resultCode, data); switch (requestCode) { case FROM_GALLERY: case FROM_CAMERA: { if (resultCode == Activity.RESULT_OK) { Uri selectedImage = data.getData(); Intent cropIntent = new Intent("com.android.camera.action.CROP"); cropIntent.setDataAndType(selectedImage, "image/*"); cropIntent.putExtra("crop", "true"); cropIntent.putExtra("aspectX", 1); cropIntent.putExtra("aspectY", 1); cropIntent.putExtra("outputX", MAX_WIDTH); cropIntent.putExtra("outputY", MAX_HEIGHT); cropIntent.putExtra("return-data", true); startActivityForResult(cropIntent, PICTURE_CROP); } break; } case PICTURE_CROP: { if (resultCode == Activity.RESULT_OK) { final Bundle extras = data.getExtras(); if (extras != null) { Bitmap photo = extras.getParcelable("data"); // Hurray! You now have the photo as a Bitmap } } break; } } } 

Update:

According to this post you should not use com.android.camera.action.CROP since this does not exist in all devices. In that post, he also enumerated alternatives which I will also list here:
