当我通过在manifest主login.java中设置主要活动来登录以填充登录页面中的用户名和密码我无法抑制或意图按钮在Activity home.java中没有响应我真的很头晕为什么按钮在活动中没有活动到两个或在home.java请帮帮我

Answer 1

我们不会在onClick上编写代码，你不能简单地比较引用：

tombol_act == button1  //that's wrong.

它类似于：

public void onClick(View view) {

switch(view.getId())
{
    case R.id.your_view1:
        // the code goes here
    break;

    case R.id.your_view2:
        // the code goes here
    break;
}

}

意图按钮在第二个活动中没有响应
