Android obtains album images and paths

I am working on a project on the Android platform. I need to use the photo album image to record it by the way, so that I can review it later. Okay, that's the end of the crap. Which of the following is a part?CodeAnd can be modified as needed ~

 

First, obtain the album image:

 

Private final string image_type = "image /*";

Private Final int image_code = 0; // The image_code here is defined by yourself.

 

// Use intent to call the album function provided by the system. startactivityforresult is used to obtain the image selected by the user.

 

Intent getalbum = new intent (intent. action_get_content );

Getalbum. settype (image_type );

Startactivityforresult (getalbum, image_code );

 

// Override onactivityresult to obtain the information you need

 

@ Override

Protected void onactivityresult (INT requestcode, int resultcode, intent data ){

If (resultcode! = Result_ OK) {// The result_ OK here is a constant defined by the system.

Log. E (TAG, "activityresult resultcode error ");

Return;

}

 

Bitmap Bm = NULL;

 

// ExternalProgramYou can access the data provided by contentprovider through the contentresolver interface.

Contentresolver resolver = getcontentresolver ();

 

// The code here is used to determine whether the received activity is the one you want.

If (requestcode = image_code ){

Try {

Uri originaluri = data. getdata (); // obtain the image URI

 

Bm = mediastore. Images. Media. getbitmap (Resolver, originaluri); // The bitmap image is displayed.

 

In the second part, obtain the image path:

 

String [] proj = {mediastore. Images. Media. Data };

 

// It seems to be an android multimedia database encapsulation interface. For details, refer to the android documentation.

Cursor cursor = managedquery (originaluri, proj, null );

// According to my personal understanding, this is the index value of the image selected by the user

Int column_index = cursor. getcolumnindexorthrow (mediastore. Images. Media. data );

// Move the cursor to the beginning. This is very important and it is easy to cross the border accidentally.

Cursor. movetofirst ();

// Obtain the image path based on the index value

String Path = cursor. getstring (column_index );

} Catch (ioexception e ){

Log. E (TAG, E. tostring ());

}

}

}
