Android call system camera to save and call the System album method

System already has something, if we do not have new requirements, direct call is the most direct. Here's how to call a system camera to take pictures and save pictures and how to call a system photo album.

First 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 by the following callback method and processed

@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.ge Textras ();
      Gets the data returned by the camera and converts it to a picture format
      Bitmap Bitmap = (Bitmap) bundle.get ("Data");
    }

Here's how to call a system photo album and get a 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). Startactivityforresult (Intent, 101);

The following callback methods are appropriate:

@Override
protected void onactivityresult (int requestcode, int resultcode, Intent data) {
   Super.onactivityresult (Requestcode, ResultCode, data);
      
   if (Requestcode = && 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, 

null);
   C.movetofirst ();
   int columnindex = C.getcolumnindex (Filepathcolumns[0]);
   String picturepath= c.getstring (columnindex);
    C.close ();
}
}

Or

@Override
protected void onactivityresult (int requestcode, int resultcode, Intent data) {
    if (ResultCode = = Activ ity. RESULT_OK) {
        switch (requestcode) {case
            :
                uri uri = Data.getdata ();
                Cursor Cursor = This.getcontentresolver (). Query (URI, NULL,
                        null, NULL, NULL);
                Cursor.movetofirst ();
String Imgno = cursor.getstring (0); Picture number 
String imgpath = cursor.getstring (1);//Picture file path 
string imgsize = cursor.getstring (2) ; Picture size 
String imgname = cursor.getstring (3);//Picture filename
                cursor.close ();
                Bitmap Bitmap = Bitmapfactory.decodefile (Imgpath);
                break;
    
            Default: Return;}}
