推荐答案

是的，它是可能的作物图像中的Andr​​oid使用 com.android.camera.action.CROP 。采摘图像的URL后，从gallery.you将开始裁剪编辑为：

Yes it's possible to crop image in android by using com.android.camera.action.CROP. after picking image url from gallery.you will start Crop Editor as:

Intent intent = new Intent("com.android.camera.action.CROP");  
intent.setClassName("com.android.camera", "com.android.camera.CropImage");  
File file = new File(filePath);  
Uri uri = Uri.fromFile(file);  
intent.setData(uri);  
intent.putExtra("crop", "true");  
intent.putExtra("aspectX", 1);  
intent.putExtra("aspectY", 1);  
intent.putExtra("outputX", 96);  
intent.putExtra("outputY", 96);  
intent.putExtra("noFaceDetection", true);  
intent.putExtra("return-data", true);                                  
startActivityForResult(intent, REQUEST_CROP_ICON);

在图片选择活动收益将被选中保存contents.in onActivityResult ：

When the picture select Activity return will be selected to save the contents.in onActivityResult:

Bundle extras = data.getExtras();  
if(extras != null ) {  
    Bitmap photo = extras.getParcelable("data");  
    ByteArrayOutputStream stream = new ByteArrayOutputStream();  
    photo.compress(Bitmap.CompressFormat.JPEG, 75, stream);  
        / / The stream to write to a file or directly using the
}
