vue父子组件传参过程：

person = personList.get(position);
AlertDialog.Builder builder = new AlertDialog.Builder(PersonActivity.this);
builder.setTitle("Delete Person").setMessage("在 Vue 中，父组件向子组件传递数据可以通过 props 实现。具体过程如下：

1.Are you sure you want to delete this person?")
.setPositiveButton("Yes", new DialogInterface.OnClickListener() {
@Override
public 在父组件中定义要传递的数据，例如：

<template>
  <div>
    <child-component :message void onClick(DialogInterface dialog, int which) {
                                SQLiteDatabase db = dbHelper.getWritableDatabase();
                                db.delete(DBOpenHelper.TABLE_STUDENT, DBOpen="msg"></child-component>
  </div>
</template>

<script>
import ChildComponent from './ChildComponent.vue';

export default {
  componentsHelper.COLUMN_STUDENT_ID + " = ?",
                                        new String[]{String.valueOf(person.getId())});
                                personList.remove(person);
                                person: {
    ChildComponent
  },
  data() {
    return {
      msg: 'Hello, child component!'
    }
  }
}
Adapter.notifyDataSetChanged();
                            }
                        }).setNegativeButton("No", null).show();
                return true;
            }
        });
    }

    private</script>

2. 在子组件中定义 props，例如：

<template>
  <div>
    <p void loadPersonList() {
        SQLiteDatabase db = dbHelper.getReadableDatabase();
        Cursor cursor = db.query(DBOpenHelper.TABLE_STUDENT, null>{{ message }}</p>
  </div>
</template>

<script>
export default {
  props: {
    message: String
  }
}
, null, null, null, null, null);
        while (cursor.moveToNext()) {
            int id = cursor.getInt(cursor.getColumnIndex(DBOpenHelper</script>

这样，父组件中的 msg 数据就会通过 props 传递给子组件的 message 属性.COLUMN_STUDENT_ID));
String name = cursor.getString(cursor.getColumnIndex(DBOpenHelper.COLUMN_STUDENT_NAME));
String myclass = cursor.getString(cursor.getColumnIndex(DBOpenHelper.COLUMN_STUDENT_CLASS));
Person person = new Person(id, name, myclass);
personList.add(person);
，子组件中就可以使用该属性进行渲染。注意，子组件中的 props 必须要声明类型，否则会收到一个警告。
