Android Select pictures from gallery, take pictures, crop pictures

I just wrote the code.

1, first, a few, usually bright.

private static final int photo_request_carema = 1;//photo
private static final int photo_request_gallery = 2;//Select from album
private static final int photo_request_cut = 3;//result
private static final String Photo_file_name = "Temp_photo.jpg";

2 Picture Clipping

private void crop (Uri uri) {
    Crop image Intent
    Intent Intent = new Intent ("Com.android.camera.action.CROP");
    Intent.setdataandtype (URI, "image/*");
    Intent.putextra ("Crop", "true");
    The scale of the cropping box, 1:1
    Intent.putextra ("Aspectx", 1);
    Intent.putextra ("Aspecty", 1);
    Size of output picture after cropping
    Intent.putextra ("Outputx", 250);
    Intent.putextra ("Outputy", 250);
    Intent.putextra ("OutputFormat", "JPEG");//Picture format
    Intent.putextra ("Nofacedetection", true);//Remove Face recognition
    Intent.putextra ("Return-data", true);
    Open an activity with a return value, the request code is Photo_request_cut
    Startactivityforresult (Intent, photo_request_cut);
}

3 Gallery Select Picture

public void Gallery (view view) {
    Activate the System gallery, select a picture
    Intent Intent = new Intent (Intent.action_pick);
    Intent.settype ("image/*");
    Open an activity with a return value, the request code is Photo_request_gallery
    Startactivityforresult (Intent, photo_request_gallery);
}

4 Camera Photo

public void camera (view view) {
    Activating the camera
    Intent Intent = new Intent ("Android.media.action.IMAGE_CAPTURE");
    Determine if the memory card is usable and can be stored
    if (Hassdcard ()) {
        Tempfile = new File (Environment.getexternalstoragedirectory (), photo_file_name);
        To create a URI from a file
        Uri uri = uri.fromfile (tempfile);
        Intent.putextra (Mediastore.extra_output, URI);
    }
    Open an activity with a return value, the request code is Photo_request_carema
    Startactivityforresult (Intent, Photo_request_carema);
}

5 return results

@Override
protected void Onactivityresult (int requestcode, int resultcode, Intent data) {
if (Requestcode = = photo_request_gallery) {
Data returned from the album
if (data! = NULL) {
Get the full path of the picture
Uri uri = Data.getdata ();
Crop (URI);
}
} else if (Requestcode = = Photo_request_carema) {
Data returned from the camera
if (Hassdcard ()) {
Crop (Uri.fromfile (tempfile));
} else {
Toast.maketext (Mainactivity.this, "No memory card found, no photos saved! ", Toast.length_long). Show ();
}
} else if (Requestcode = = photo_request_cut) {
Data returned from the cut image
if (data! = NULL) {
Bitmap Bitmap = Data.getparcelableextra ("Data");
This.image.setImageBitmap (bitmap);
}
try {
Delete a temporary file
Tempfile.delete ();
} catch (Exception e) {
E.printstacktrace ();
}
}
Super.onactivityresult (Requestcode, ResultCode, data);
}

6 Determine if the sdcard is being mounted

Private Boolean Hassdcard () {
    if (Environment.getexternalstoragestate (). Equals (
            environment.media_mounted)) {
        return true;
    } else {
        return false;
    }
}

7onCreate, do it yourself.

That's all.
