事情是......在一个Activity中我填写一些字段来popularem一个ListView被加载到另一个Acitivity,试图在同一个Activity中显示它并且工作,当我试图在另一个中显示它时发生错误能力,我相信它与上下文有关。
用于填充参数的Activity,如果显示列表,则该函数称为FiltrarImoveis,其中此步骤仅在ArrayAdapter的上下文中。
提供问题的Activity被称为DetalhesImoveis,尝试传递此信息,DetalhesImoveis.this并继续给出错误...以下是给出错误的代码的Activity部分:
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
ArrayList<String> listaImoveis = new ArrayList<String>();
listaImoveis.add("foo");
listaImoveis.add("bar");
ArrayAdapter<String> adpImovel = new ArrayAdapter<String>(DetalhesImoveis.this,android.R.layout.simple_list_item_1, listaImoveis);
lvImoveis.setAdapter(adpImovel);
}
