JsonToForms

A simple library which uses JSON to build forms : JSON Form Builder.

JsonToForms

Installation

Step 1. Add the JitPack repository to your build file:

repositories {
	...
	maven { url 'https://jitpack.io' }
	}
Bash

Step 2. Add the dependency

dependencies {
	  implementation 'com.github.MohdShamweel:JsonToForms:0.1.0'
                
     //Support Material dependency
     implementation 'com.google.android.material:material:1.1.0-alpha09'
	     }
Bash

Step 3. The dependency contains Java 8 bytecode. Add the following to build.gradle

           android {
               compileOptions {
                   sourceCompatibility 1.8
                   targetCompatibility 1.8
               }
           }
Bash

Step 4. The Activity which contains forms must be a descendant of Material Theme:

parent="Theme.MaterialComponents.Light.DarkActionBar"
Bash

Step 5. Sync the Project for gradle to finish.

Usage

  1. Initialize the Hashmap (basically it clears the list):
DataValueHashMap.init();
Bash
  1. Use the adapter and Object of this library:
FormAdapter mAdapter;
List<JSONModel> jsonModelList = new ArrayList<>();
Bash
  1. Initialize the adapter:
mAdapter = new FormAdapter(jsonModelList, this, this);
Bash
  1. Implement your Activity to access methods
implements JsonToFormClickListener
  1. Implemented Methods
 @Override
    public void onAddAgainButtonClick() {
        Toast.makeText(this, "Add Again button click", Toast.LENGTH_SHORT).show();
    }

 @Override
    public void onSubmitButtonClick() {
        Toast.makeText(this, "Add Submit button click", Toast.LENGTH_SHORT).show();
    }
Bash
  1. To check if fields are validated use the method:
if (!CheckFieldValidations.isFieldsValidated(recyclerView, jsonModelList)){
            Toast.makeText(this, "Validation Failed", Toast.LENGTH_SHORT).show();
    }
Bash
  1. To get data:
//Combined Data:
   JSONObject jsonObject = new JSONObject(DataValueHashMap.dataValueHashMap);
   Log.d("onSubmitButtonClick: ", jsonObject.toString());


//If single value required for corresponding _id's:
   for (Map.Entry<String, String> hashMap : DataValueHashMap.dataValueHashMap.entrySet()){
       String key = hashMap.getKey(); //  _id of the JSONOModel provided
       String value = hashMap.getValue(); //value entered for the corresponding _id
       Log.d(key, value);
     }
Bash

Fields Types

TYPE_TEXT = 1;
TYPE_EDITTEXT = 2;
TYPE_SPINNER = 3;
TYPE_RADIO = 4;
TYPE_DATE = 5;
TYPE_SPACE = 6;
TYPE_CHECKBOX = 7;
TYPE_ADD_AGAIN_BUTTON = 9;
TYPE_SUBMIT_BUTTON = 10;
