Android calls the System camera to save and call the system album Method

If there are no new requirements for the system, direct calls are the most direct. The following describes how to call a system camera to take pictures and save images and call a system album. First, let's take a look at the core method of calling the System camera: Intent camera = new Intent (MediaStore. ACTION_IMAGE_CAPTURE); startActivityForResult (camera, 100); the data returned by the camera is obtained through the following callback method, and the copy code @ Override protected void onActivityResult (int requestCode, int resultCode, Intent data) {super. onActivityResult (requestCode, resultCode, data); if (requestCode = CAMERA & resultCode = Activity. RESULT_ OK & null! = Data) {Bundle bundle = data. getExtras (); // get the data returned by the camera and convert it to the image format Bitmap bitmap = (Bitmap) bundle. get ("data") ;}} copy the code. The following describes how to call the system album and obtain the photo: Intent picture = new Intent (Intent. ACTION_PICK, android. provider. mediaStore. images. media. EXTERNAL_CONTENT_URI); startActivityForResult (picture, 101); or intent = new Intent (); intent. setType ("image/*"); intent. setAction (Intent. ACTION_GET_CONTENT); (Activity) context ). startAc TivityForResult (intent, 101); below is the corresponding callback method: copy the code @ Overrideprotected void onActivityResult (int requestCode, int resultCode, Intent data) {super. onActivityResult (requestCode, resultCode, data); if (requestCode = 101 & resultCode = Activity. RESULT_ OK & null! = Data) {Uri selectedImage = data. getData (); String [] filePathColumns = {MediaStore. images. media. DATA}; Cursor c = this. getContentResolver (). query (selectedImage, filePathColumns, null, null); c. moveToFirst (); int columnIndex = c. getColumnIndex (filePathColumns [0]); String picturePath = c. getString (columnIndex); c. close () ;}} copy the code or copy the code @ Overrideprotected void onActivityResult (int requestCode, int resultCode, Intent data) {if (resultCode = Activity. RESULT_ OK) {switch (requestCode) {case 101: Uri uri = data. getData (); Cursor cursor = this. getContentResolver (). query (uri, null, null); cursor. moveToFirst (); String imgNo = cursor. getString (0); // Image number String imgPath = cursor. getString (1); // image file path String imgSize = cursor. getString (2); // image size String imgName = cursor. getString (3); // the image file name cursor. close (); Bitmap bitmap = BitmapFactory. decodeFile (imgPath); break; default: return ;}}}
