Croppedimage function 裁剪图像功能
public void Croppedimage(CropImage.ActivityResult result,ImageView iv)

}
//set image to image view
iv.setImageURI(resultUri);

The problem 问题
The cropped image for second Button
set in first Imageview
. 在第一个Imageview
设置的第二个Button
的裁剪图像。 Need to find way to reach to iv1
in onActivityResult
for second camera Button
. 需要在第二个Camera Button
onActivityResult
找到到达iv1
方法。
Any suggestions? 有什么建议么?
Library use for crop image 库用于裁剪图像
THANKS. 谢谢。
Looking in the issues on the GitHub respository I found this one , that seems similar to yours, you can set a custom request code when starting the crop activity. 在GitHub储存库上的问题中,我发现了一个与您的储存库类似的问题,您可以在开始裁剪活动时设置自定义请求代码。
So you can start the activity with 2 different request codes and check which one has been used on onActivityResult
因此,您可以使用2个不同的请求代码启动活动,并检查onActivityResult
使用了哪个请求代码
private static final RC_CROP = 100;
private static final RC_CROP1 = 200;
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == RESULT_OK) // resultCode: -1
{
if (requestCode == CAMERA_REQUEST_CODE) // requestCode: 288
{
Uri picUri = pictureUri;
startCropImageActivity(picUri, RC_CROP);
Toast.makeText(MainActivity.this, "Image 1 save",
Toast.LENGTH_SHORT).show();
}
if (requestCode == CAMERA_REQUEST_CODE1) {
Uri picUri = pictureUri;
startCropImageActivity(picUri, RC_CROP1);
Toast.makeText(MainActivity.this, "Image 2 save",
Toast.LENGTH_SHORT).show();
}
if (requestCode == RC_CROP) {
CropImage.ActivityResult result = CropImage.getActivityResult(data);
//put image on first ImageView
}
if (requestCode == RC_CROP1) {
CropImage.ActivityResult result = CropImage.getActivityResult(data);
//put image on second ImageView
}
} else if (resultCode == CropImage.CROP_IMAGE_ACTIVITY_RESULT_ERROR_CODE) {
// if there is any error show it
Exception error = result.getError();
Toast.makeText(this, "" + error, Toast.LENGTH_LONG).show();
}
}
private void startCropImageActivity(Uri imageUri, int requestCode) {
Intent vCropIntent = CropImage.activity(imageUri)
.setGuidelines(CropImageView.Guidelines.ON)
.setMultiTouchEnabled(true)
.getIntent(this);
startActivityForResult(vCropIntent, requestCode)
}
I suggest also to use a switch statement when checking the requestCode 我建议在检查requestCode时也使用switch语句
