复制小程序

Feature: 点击选择拍照或者打开相册，选取图片进行裁剪最后设置为圆形头像。

Problem: 拍好照片，点击裁剪，弹Toast“无法加载此图片”。

Solution: 在裁剪的class里加两行代码

intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
intent.addFlags(Intent.FLAG_GRANT_WRITE_URI_PERMISSION);


主要代码如下：


public static final String PHOTO_IMAGE_FILE_NAME = "fileImg.jpg";
public static final int CAMERA_REQUEST_CODE = 100;
public static final int IMAGE_REQUEST_CODE = 101;
public static final int RESULT_REQUEST_CODE = 102;
private File tempFile = null;
private Uri imageUri; //跳转相机
private void toCamera() { File outputImage = new File(getActivity().getExternalCacheDir(),
PHOTO_IMAGE_FILE_NAME);
try {
if (outputImage.exists()) {
outputImage.delete();
}
outputImage.createNewFile();
} catch (IOException e) {
e.printStackTrace();
} if (Build.VERSION.SDK_INT >= 24) {
imageUri = FileProvider.getUriForFile(getActivity(),
"com.liushengjie.smartbutler.fileprovider", outputImage);
} else {
imageUri = Uri.fromFile(outputImage);
}
//启动相机程序
Intent intent = new Intent("android.media.action.IMAGE_CAPTURE");
intent.putExtra(MediaStore.EXTRA_OUTPUT, imageUri);
startActivityForResult(intent, CAMERA_REQUEST_CODE);
dialog.dismiss(); } //跳转相册
private void toPicture() {
Intent intent = new Intent(Intent.ACTION_PICK);
intent.setType("image/*");
startActivityForResult(intent, IMAGE_REQUEST_CODE);
dialog.dismiss();
} @Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode != getActivity().RESULT_CANCELED) {
switch (requestCode) {
//相机数据
case CAMERA_REQUEST_CODE:
//tempFile = new File(Environment.getExternalStorageDirectory(), PHOTO_IMAGE_FILE_NAME);
//startPhotoZoom(Uri.fromFile(tempFile));
startPhotoZoom(imageUri);
break;
//相册数据
case IMAGE_REQUEST_CODE:
startPhotoZoom(data.getData());
break;
case RESULT_REQUEST_CODE:
//有可能点击舍弃
if (data != null) {
//拿到图片设置
setImageToView(data);
//删除原来的图片
if (tempFile != null) {
tempFile.delete();
}
}
break;
}
}
} //裁剪
private void startPhotoZoom(Uri uri) {
if (uri == null) {
L.e("uri == null");
return;
} Intent intent = new Intent("com.android.camera.action.CROP");
intent.setDataAndType(uri, "image/*");
intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
intent.addFlags(Intent.FLAG_GRANT_WRITE_URI_PERMISSION);
//裁剪
intent.putExtra("crop", true);
//宽高比例
intent.putExtra("aspectX", 1);
intent.putExtra("aspectY", 1);
//图片质量
intent.putExtra("outputX", 320);
intent.putExtra("outputY", 320);
//发送数据
intent.putExtra("return-data", true);
startActivityForResult(intent, RESULT_REQUEST_CODE);
} //设置图片
private void setImageToView(Intent data) {
Bundle bundle = data.getExtras();
if (bundle != null) {
Bitmap bitmap = bundle.getParcelable("data");
profile_image.setImageBitmap(bitmap);
}
}
