后端核心代码

final View view = LayoutInflater.from(DialogActivity.this).inflate(R.layout.activity_login, null);
final EditText userName = view.findViewById(R.id.userName);
EditText passWord = view.findViewById(R.id.passWord);
Button btn = view.findViewById(R.id.Login);
final AlertDialog.Builder builder4 = new AlertDialog.Builder(DialogActivity.this);
builder4.setTitle("登入").setView(view).show();
btn.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        //获取登入框帐号userName.getText().toString() 密码  passWord.getText().toString()
        //这里可以做一些登入的逻辑代码
        //Toast.makeText(DialogActivity.this,array3[which],Toast.LENGTH_LONG);
    }
});
