How to open the system image library and use images in the dialog class

=============== Problem description ====================

The younger brother's project is a jar package containing a page written by dialog. He wants to open the system image library on the page.

If it is in activity, you can

startActivityForResult(new Intent(....),1);

.

How to implement it in dialog.

============= Solution 1 ======================

You can use getcontext (). startactivity (). The same is true, right? You can get the corresponding context object.

============= Solution 2 ======================

I did this in the project.
Customize the dialog, add a callback interface, and set the listening method in the activity to achieve redirection.

Private onoptionclicklistener optionclicklistener = new onoptionclicklistener () {@ overridepublic void onoptionclick (popudialog dialog, int position) {// todo auto-generated method stubif (position = 0) {// photograph intent = new intent (mediastore. action_image_capture); startactivityforresult (intent, requestcode_takephoto);} else if (position = 1) {// select intent = new intent () in the Image Library (); /* enable pictures to set the image type to image */intent. settype ("image/*");/* use intent. action_get_content this action */intent. setaction (intent. action_get_content);/* returns the current screen after obtaining the photo */startactivityforresult (intent, requestcode_selectphoto );}}};

Is it helpful to you?

============= Solution 3 ======================

Upstairs, you can get a returned message through startactivityforresult, and then rewrite it in your fragment class.

Onactivityresult, and then you can get data from the returned bundle. Remember to use

Bitmap BMP = (Bitmap) bundle. getserilizable ("data ");

To obtain the selected image. Of course, this is related to the activity selected for the opened image.
