1. Name
Name the app: MyNotePad and my notebook. The app icon adopts the default icon. Just set the app name.
The project has been placed in gitee: MyNotePad
2. Function description
- For Hongmeng application development API V6, it may not have rich text components. Read the relevant documents. Some functions of rich text components will not take effect until AP1 V8. There is no api Hongmeng component usage about rich text on the Internet. Therefore, we decided to use TextField and Image components and ScrollView component to simulate a rich text component, which is called pseudo rich text.
- With note editing function, you can edit text, insert pictures, and finally save them in the storage space of the application sandbox.
- When editing, slide the input box to the left, and a delete button is displayed on the right side; Slide right to hide the delete button. It realizes this common and convenient function of Android mobile phones. Of course, you can also long press the text input box or picture to delete.
- It realizes the selection of pictures from the system album or file, and then decodes them and displays them in the Image component. When saving, the decoded pictures are re encoded and saved in the folder created by the application sandbox.
- The read and write operations of application sandbox storage are realized.
- A series of folders are created, and the structure of File directory is generated through the designed storage structure, which is convenient to directly obtain the File variable call of files when storing or reading.
- When using ListContainer to display the note list, sliding up the note list will hide the upper area and expand the vertical range of the list. Sliding down the note list will display the original function area, which realizes the function operation created by the app now.
- After clicking "select", a selected area will appear on the left of each item in the note list. If it is selected, a green check mark will be displayed. If it does not want to be selected, the green check mark will not be displayed, realizing the deletion management function of the list items created by the app.
- The function of searching matching notes through key sentences is realized. If there is, the notes will be loaded directly and enter the editing page. If not, toast prompt text will be displayed!
3. Key skills of APP implementation
3.1 slide the note list to change the display space, slide the note entry display left, and slide the delete key right to disappear
Implementation skills:
- When sliding up the note list, the touch event is triggered and it is judged that it is sliding up. Then set the upper layout container component to HIDE. At this time, the upper part does not occupy space, so the vertical display space of the list is expanded. When sliding the list, if it is judged that it is sliding, set the upper layout container component to VISIBLE to achieve the purpose of restoration.
- When sliding left on a note item, a touch event is triggered. If it is judged that it is sliding left, set the red "delete" button on the far right to VISIBLE. When sliding to the right, set it to HIDE to achieve this common deletion effect.
3.2 click "select" and a selection box will appear on the left of each note entry, and "Cancel" and "delete" will be displayed at the bottom
Implementation skills:
- The sub layout of the ListContainer is reusable and dynamically loaded. In writing the sub layout XML, let the click selection Text on the left side be set to HIDE by default. When the user clicks "select", it will traverse all the components currently loaded by the ListContainer, and then set the click selection box on each left side to visible.
- When you click "Cancel", set each click box to HIDE, Text to "N" and Text color to whee according to the above traversal method.
- If the Text of a click box is "N", set its Text to“ ✔”， Set the Text color to "GREEN"; If a click box is clicked, the Text at this time is“ ✔”， Then the Text of Text is set to "N" and the Text color is set to WHIE. You can achieve the effect of selecting or not selecting after clicking.
- Click "delete" to traverse the components that have been loaded in the ListContainer at this time. When the text content of the left click box is“ ✔”， Get the File variable of the folder where the note is located through the ListContainer's data source list (a generic ArrayList), and then delete all files in the folder through traversal. Finally, remove the data from the data source list, and finally refresh the ListContainer.
3.3 search function
Implementation skills:
- Traverse all the short text of notes in the ListContainer at this time, and judge whether there are matching note entries by using indexof (search the text of the input box). If there are, open the note directly. If not, the Toast prompt will be displayed.
3.4 pseudo rich text editing function (text and picture)
Implementation skills:
- Firstly, there needs to be a ScrollView component, and then TextField or Image components need to be added dynamically as needed, and there will be a recordlist (a generic ArrayList) to record the component order of the current editing area (so that the file name can be prepared according to this order when storing data and recovered according to this file name order when reading data), The "pseudo rich text" function can be realized. Look forward to the rich text components launched by the subsequent API!
- Click "save" to first judge whether the first text input box is empty. If it is not empty, it will be saved. If it is empty, a Toast prompt will be displayed. When saving, you need to traverse each item in the recordlist and identify it according to the component type in each item. If it is TextField, you need to use the corresponding stream processing storage according to the storage method of text file. If it is Image, you need to encode it first and build the target file to package it. At this time, the record saving status is true.
3.5 get the directory structure of the note folder (important operation) (stored in the application sandbox instead of the external private storage of the application)
The folder organization of this note is as follows:
Automatically obtain the date of each day and create a daily folder dayfolder. The folder is the folder thisnote folder of each note in the editing order of that day. In this folder, the files are named and stored according to the sequence of components recorded in the recordlist. If there are already two files in the folder of the day, the folder name of the third note of the day will be incremented in order (use dayfolder. List() length+1)
[generate usernote folder directory structure] an ArrayList generic list (ArrayList StructFile dayfolders = new ArrayList < > ()) is used. There are two variables in this type of StructFile. One variable File dayfile is used to save the File of a folder on a certain day, and the other variable File [] dayfile_ Notelist files is used to save all notes in the folder of that day. In this way, the structure of usernote folder is generated, and the "handle" of all folders is held in hand for easy operation! The schematic diagram is as follows:
