Android将值从活动传递到适配器 [英] Android pass value from activity to adapter

问题描述

我想将变量从活动传递到适配器.

I want to pass variable from activity to adapter.

我的适配器看起来像这样

My adapter looks like this

  public SampleAdapter(Activity context, ArrayList<SampleBeans> data){
  this.context = context;
  this.data = data;
  }

我的活动看起来像这样

  newadapter = new SampleAdapter(this);
  newadapter.setId(Login_uuid_value);

给我错误SampleAdapter无法应用于活动.

Gives me error SampleAdapter cannot be applied to the activity.

推荐答案

只需将值添加到构造函数中.

Simply add the values to the constructor.

public SimpleAdapter(Activity context, ArrayList<SimpleBeans> data, String mystring, int myInt){
  //use datas here
}

并像使用它

myAdapter = new SimpleAdapter(this, data, myString, myInt);

当然，您可以设置所需的所有数据，例如.

Obiouvsly you can set all the datas you want, mine were some examples.

在您的情况下，您只需要将arrayList添加到构造函数中即可.

In your case you simply need to add the arrayList to the constructor.

myAdapter = new SimpleAdapter(this, myArrayList);
