A while ago I wrote how to get albums and photos after taking them and display and upload them. This time I made circular images. People who often read my notes will know that I am lazy.Then I'm lazy and self-defined, and the current needs are just as good as the original, the wheel of the Great God, which I'll recommend later.This note relies on: Android calls albums, cameras (compatible with 6.0, 7.0, 8.0)
The article was written, so it won't be basic. Please check that first.
First effect Ha:
##1. Layout settings
Because it is a round picture, we quote a world-famous project: CircleImageView
<?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" tools:context=".MainActivity"> <Button android:id="@+id/btn_get_pic_form_photo_album" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentStart="true" android:layout_margin="10dp" android:text="Call album" /> <Button android:id="@+id/btn_get_Permission" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_centerHorizontal="true" android:layout_margin="10dp" android:text="Dynamic Permission Request" /> <Button android:id="@+id/btn_get_pic_from_camera" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentEnd="true" android:layout_margin="10dp" android:text="Call Camera" /> <de.hdodenhof.circleimageview.CircleImageView android:id="@+id/iv_test" android:layout_width="96dp" android:layout_height="96dp" android:layout_centerInParent="true" android:src="@drawable/ic_launcher_background" app:civ_border_color="#999999" app:civ_border_width="2dp" /> </RelativeLayout>
The layout hasn't changed much by changing the previous ImageView to a CircleImageView control
##2,.java file
Two methods have been added here
Method One of #######
private void photoClip(Uri uri) { // Call the picture clipping that comes with the system Intent intent = new Intent("com.android.camera.action.CROP"); intent.setFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION | Intent.FLAG_GRANT_WRITE_URI_PERMISSION); intent.setDataAndType(uri, "image/*"); // The crop=true below is set to set the VIEW clippable display in the open Intent intent.putExtra("crop", "true"); // aspectX aspectY is the ratio of width to height intent.putExtra("aspectX", 1); intent.putExtra("aspectY", 1); // outputX outputY is the width and height of the cropped picture intent.putExtra("outputX", 150); intent.putExtra("outputY", 150); intent.putExtra("return-data", true); startActivityForResult(intent, 3); }
This method passes in the uri of the photo we get to activate the clipping interface of the Android system.I called this method within onActivityResult.
Method 2 of #######
public String saveImage(String name, Bitmap bmp) { File appDir = new File(Environment.getExternalStorageDirectory().getPath()); if (!appDir.exists()) { appDir.mkdir(); } String fileName = name + ".jpg"; File file = new File(appDir, fileName); try { FileOutputStream fos = new FileOutputStream(file); bmp.compress(Bitmap.CompressFormat.PNG, 100, fos); fos.flush(); fos.close(); return file.getAbsolutePath(); } catch (IOException e) { e.printStackTrace(); } return null; }
This method passes in the bitmap to get the photo and the name of the clipped photo, and the path to save the file. Han Xiaodian saves it in the local root directory.

When the code was written like this, I thought I could finish it, but when I took out my millet 4 and millet 8se tests, I was confused and the following results appeared:
Describe:
1. After the album has selected the photo, as long as the photo is clipped, an error will occur during the save and the save will fail.
2. Clipping after taking a photo has no effect.
#3. Solving bug s
###1, add the following code to the photoClip() method, and leave the rest unchanged
uritempFile = Uri.parse("file://" + "/" + Environment.getExternalStorageDirectory().getPath() + "/" + System.currentTimeMillis() + ".jpg"); intent.putExtra(MediaStore.EXTRA_OUTPUT, uritempFile); intent.putExtra("outputFormat", Bitmap.CompressFormat.JPEG.toString()); intent.putExtra("noFaceDetection", true);
The uritempFile here is a Uri.
###2, add the following code to the clipped return successful return method:
Picasso.with(EditMyInfoActivity.this).load(uritempFile).into(ivHead); File file = null; try { file = new File(new URI(uritempFile.toString())); } catch (URISyntaxException e) { e.printStackTrace(); } //Photo Path String path = Objects.requireNonNull(file).getPath();
Then you can run perfectly.
##3. Recommend a custom clipped blog
Android high mimic WeChat avatar intercepts to create different custom controls - - Author: the well-known Zhang Hongyang
##4. Recommend several clipping frames
1,uCrop - Mint, beer and beer in use
2,android-crop - NetEase News, Mango TV in use
3,PhotoCrop - Fast-hand use
4,CropBitmap ->From a group friend of Niu x
