从RecycleView适配器启动活动上点击 [英] Start Activity from RecycleView Adapter on click

问题描述

我已经开始从CardView适配器一个新的活动的问题，这是code：

I have an issue starting a new activity from a CardView Adapter, this is the code:

RVAdapter adapter = new RVAdapter(array_restaurants);
recList.setAdapter(adapter);

和之后在适配器。我设置一个OnClickListener

And after in the adapter. I set an OnClickListener

personName.setOnClickListener(new View.OnClickListener(){

            @Override
            public void onClick(View v) {
                Context context = v.getContext();
                System.out.println("Context");
                System.out.println(context.toString());
                Intent intent = new Intent(v.getContext(), Restaurante.class);
                v.getContext().startActivity(intent);
            }
        });

当我打印的背景下，在控制台一切看起来正常，但aplication后停止工作。为什么呢？

When i print the context in the console everything looks fine, but after the aplication stop working. Why?

非常感谢你。

推荐答案

在很多时候，我找到了答案，答案是那些人提出帮我发现的主要问题，这是解决方案

After a lot of time I found an answer, the answer that those people submit help me to found the main problem, this was the solution

在MainActivity我增加了一个新的参数和活动传递给适配器，如@Meenal Sharma和建议@ ch3tan

In the MainActivity I added a new parameter and pass the activity to the adapter, like @Meenal Sharma and @ch3tan proposed

RVAdapter adapter = new RVAdapter(restaurantes, this);

和在适配器

  public Adaptador(List<Restaurant> restaurants, Context context) {
    this.restaurants = restaurants;
    this.context = context;
}

和创造的意图：

Intent intent = new Intent(context, RestaurantActivity.class);
context.startActivity(intent);

这部分解决了一个错误，但是，我不得不是，当我创建了Android Studio中创建新活动继承ActionBarActivity的新活动的主要错误，我改变ActionBarActivity的AppCompatActivity，一切​​又激动...

That part solve an error but the main error that i had was, when I created a new activity with the Android Studio that created the new activity inheriting of ActionBarActivity, I changed ActionBarActivity for AppCompatActivity and everything worked again...
