Android micro-letter Image browsing Framework design _android

First, the business scene

1, chat interface to send pictures ==> multiple selection + have the top right corner "send" + picture preview ==> Picture Preview support the top right corner "send" logic
2, published dynamic ==> multiple selection + top right Corner "complete" + Picture preview ==> Picture Preview support the top right corner "complete" logic
3, Personal data change Avatar ==> single point selection + Picture preview screenshot ==> picture preview screenshot Support "use" logic in upper right corner

second, the intent parameter design; (Intent principle: Try not to use custom type-specific parameters)

1, the most basic parameter transfer (the maximum number of optional pictures, the title in the top right corner, the radio mode or the multiple selection mode, return the results of the parameters)

  /** maximum picture selection times, int type, default 9 *
  /public static final String Extra_select_count = "Max_select_count";

  /** send button title such as Complete or send * * public
  static final String extra_submit_title = "Extra_submit_title";

  /** picture selection mode, the default multiple select
  /public static final String Extra_select_mode = "Select_count_mode";

  /** Select result, return to arraylist<string> picture path set
  /public static final String Extra_result = "Select_result";

2, extended part of the parameter transfer (Picture selection interface of the first item whether to display the camera function, the activity of the preview supports the "Check Cancel" check button)

 /** whether the camera is displayed, the default display *
  /public static final String Extra_show_camera = "Show_camera";

  /** whether to jump to imagedetailcheckpicsact
  /public static final String extra_jumptocheckpics = "Is_jumpto_checkpics";

3, in the "Publish Dynamic Selection" has selected 5 pictures, and then to choose Pictures-image browser needs to select the selected picture Check status set to tick

 /** default has been selected Set *
  /public static final String extra_default_selected_list = "Default_list";

4, screenshot function (in the single selection mode, if the start screenshot mode, then jump screenshot after selection interface)

  /** whether the original image return or first jump screenshot after return * * public
  static final String resizebit = "Resizebit";
  /** screenshot Save Path * * Public
  static final String result = "Resultpath";
  /** whether the screenshot/public
  static final String Mode_scale_boolean = "Mode_scale_boolean";
  /** Single screenshot area blue box width, unit DP/public
  static final String Scalew = "Scalew";
  /** Single screenshot area blue box high, unit DP/public
  static final String Scaleh = "Scaleh";
  /** the image saved pixel width after the single screenshot, the unit SP/public
  static final String LIMITW = "Limitwidth";
  /** the image saved after a single screenshot of the high pixel, the unit SP/public
  static final String Limith = "Limithight";
  /** the saved path of the screenshot of the radio
  /public static final String Mode_scale_path = "Mode_scale_path";

Third, the design after clear requirements

Four, code use method

 public static void Jumptoselectpics (Activity mcontext, Boolean isshowcamera, int selectmaxcount, int selectmode, S Tring Submitbtnstr, Boolean isjumptocheckpics, arraylist<string> hasselectlist) {Intent Intent = new Intent (mCo

  Extra_default_selected_list if (hasselectlist!= null) {    Intent.putstringarraylistextra (Multiimageselectoractivity.extra_default_selected_list, hasSelectList);
  }//Mcontext.startactivityforresult (Intent, request_image);  /** * Picture format JPEG * @param picresultpath image to be saved address * @param the width of the Scalew screenshot area DP * @param scaleh the height of the screenshot area Unit DP * @param the width of the graph cropped by the limtwidth * @param the height of the limithight cropped graph * @param isscaleimg is in accordance with Limtwidth, Limithight ratio * @description: * @author Zhangjianlin (990996641) * @date June 11, 2015 afternoon 4:25:00/public static Voi D jumptoselecandcropimg (Activity mcontext, String picresultpath, int scalew, int scaleh, int limtwidth, int limithig

    Max Select Image Amount Intent.putextra (Multiimageselectoractivity.extra_select_count, 1); Select Mode (MulTiimageselectoractivity.mode_single OR Multiimageselectoractivity.mode_multi) Intent.putextra (

    Intent.putextra (Cropimageact.scalew, Scalew);
    Intent.putextra (Cropimageact.scaleh, Scaleh);
