передавать объекты класса между действиями с parcelable

0 голосов
/ 10 апреля 2020

Я пытаюсь отправить объект класса между двумя actvities с parcelable, кажется, что он хорошо применен, я реализовал parcelable и затем передал его через намерение, но мое приложение остановилось без каких-либо действий, мне нужна помощь !!

Это мой класс: 

public class myTasks implements Parcelable {

String title_task, desc_task, prio_task, diff_task, date_task;

public myTasks(){
}

public myTasks(String title_task, String desc_task, String prio_task, String diff_task, String date_task) {
    this.title_task = title_task;
    this.desc_task = desc_task;
    this.prio_task = prio_task;
    this.diff_task = diff_task;
    this.date_task = date_task;
}

protected myTasks(Parcel in) {
    title_task = in.readString();
    desc_task = in.readString();
    prio_task = in.readString();
    diff_task = in.readString();
    date_task = in.readString();
}

public static final Creator<myTasks> CREATOR = new Parcelable.Creator<myTasks>() {
    public myTasks createFromParcel(Parcel in) {
        return new myTasks(in);
    }

    public myTasks[] newArray(int size) {
        return new myTasks[size];
    }
};

public String getTitle_task() {
    return title_task;
}

public void setTitle_task(String title_task) {
    this.title_task = title_task;
}

public String getDesc_task() {
    return desc_task;
}

public void setDesc_task(String desc_task) {
    this.desc_task = desc_task;
}

public String getPrio_task() {
    return prio_task;
}

public void setPrio_task(String prio_task) {
    this.prio_task = prio_task;
}

public String getDiff_task() {
    return diff_task;
}

public void setDiff_task(String diff_task) {
    this.diff_task = diff_task;
}

public String getDate_task() {
    return date_task;
}

public void setDate_task(String date_task) {
    this.date_task = date_task;
}

@Override
public int describeContents() {
    return 0;
}

@Override
public void writeToParcel(Parcel parcel, int i) {
    parcel.writeString(title_task);
    parcel.writeString(desc_task);
    parcel.writeString(prio_task);
    parcel.writeString(diff_task);
    parcel.writeString(date_task);
}

}

Это источник Упражнение: 

public class taskAdd extends AppCompatActivity {

TextView title_page, add_title, add_desc, add_date, add_prio, add_diff;
EditText title_task, desc_task, date_task, prio_task, diff_task;
//button
Button btn_save, btn_cancel;

ArrayList<myTasks> dataList;

//task counter
Integer task_num = new Random().nextInt();
String key_task = Integer.toString( task_num);

@Override
protected void onCreate(Bundle savedInstanceState){
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_task_add);

    //definition of the variables
    title_page = findViewById(R.id.title_page);

    add_title = findViewById(R.id.add_title);
    add_desc = findViewById(R.id.add_desc);
    add_date = findViewById(R.id.add_date);
    add_prio = findViewById(R.id.add_prio);
    add_diff = findViewById(R.id.add_diff);

    title_task = findViewById(R.id.title_task);
    desc_task = findViewById(R.id.desc_task);
    date_task = findViewById(R.id.date_task);
    prio_task = findViewById(R.id.prio_task);
    diff_task = findViewById(R.id.diff_task);

    btn_save = findViewById(R.id.btn_save);
    btn_cancel = findViewById(R.id.btn_cancel);
    /*#####################################################*/
    //recuperation of data
    btn_save.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {

            //fil the object item_task with data
            myTasks task = new myTasks();

            task.setTitle_task(title_task.getText().toString());
            task.setDesc_task(desc_task.getText().toString());
            task.setPrio_task(prio_task.getText().toString());
            task.setDiff_task(diff_task.getText().toString());
            task.setDate_task(date_task.getText().toString());

            Log.i("TAG","Le titre de tâche est =" + " " +task.getTitle_task());

            Intent intent = new Intent(taskAdd.this,MainActivity.class);
            intent.putExtra("parcel_data", task);
            startActivity(intent);
        }
    });
    /*#######################################################*/

    // import font
    Typeface MLight = Typeface.createFromAsset(getAssets(), "fonts/ML.ttf");
    Typeface MMedium = Typeface.createFromAsset(getAssets(), "fonts/MM.ttf");

    // customize font
    title_page.setTypeface(MMedium);

    add_title.setTypeface(MLight);
    title_task.setTypeface(MMedium);

    add_desc.setTypeface(MLight);
    desc_task.setTypeface(MMedium);

    add_date.setTypeface(MLight);
    date_task.setTypeface(MMedium);

    add_prio.setTypeface(MLight);
    prio_task.setTypeface(MMedium);

    add_diff.setTypeface(MLight);
    diff_task.setTypeface(MMedium);

    btn_save.setTypeface(MMedium);
    btn_cancel.setTypeface(MLight);
}

}

Это целевая активность: 

public class MainActivity extends AppCompatActivity {

TextView title_page, sub_title_page, end_page;
Button buttonNewTask;

// 1- Declare RecyclerView
RecyclerView ourtasks;

// 2- Declare arrayList of tasks & Adapter
ArrayList<myTasks> taskList;

tasksAdapter adapter;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    title_page = findViewById(R.id.title_page);
    sub_title_page = findViewById(R.id.sub_title_page);
    end_page = findViewById(R.id.end_page);

    buttonNewTask = findViewById(R.id.buttonNewTask);

    // import font
    Typeface MLight = Typeface.createFromAsset(getAssets(), "fonts/ML.ttf");
    Typeface MMedium = Typeface.createFromAsset(getAssets(), "fonts/MM.ttf");

    // customize font
    title_page.setTypeface(MMedium);
    sub_title_page.setTypeface(MLight);
    end_page.setTypeface(MLight);

    //button font
    buttonNewTask.setTypeface(MLight);

    buttonNewTask.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            //start a task add activity when button pressed
            Intent a = new Intent(MainActivity.this,taskAdd.class);
            startActivity(a);
        }
    });

    //working with data
    ourtasks = findViewById(R.id.ourtasks);
    ourtasks.setLayoutManager(new LinearLayoutManager(this));
    taskList = new ArrayList<myTasks>();


    myTasks task = (myTasks) getIntent().getParcelableExtra("parcel_data");

    taskList.add(task);
    Log.i("TAG","===========================" + " " +task.getPrio_task());

    adapter = new tasksAdapter(MainActivity.this,taskList);
    ourtasks.setAdapter(adapter);
}
