Question

我使用共享偏好设置，以便在第一次登录后，下次用户启动应用时，不应打开SignInActivity。在使用共享偏好设置 ＆＃34; onClickbuttonListener＆＃34; 之前效果很好并打开了SignInActivity，但后来我删除了Sharedpreferences代码，然后点击按钮不会再次打开 SignInActivity 。请帮帮我。在 onClickListener（）中，如果我添加其他活动而不是SignInActivity，则可以正常工作，

主要活动

 public  void onClickButtonListener(){
    signUpBtn = (Button)findViewById(R.id.button);
    signUpBtn.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {

        Intent intent = new Intent(getApplicationContext(), SignInActivity.class);
        startActivity(intent);   
        }
    });
}

logcat的

Answer 1

您必须在活动中创建方法goSignInActivity。

public void goSignInActivity(View v) {
    Intent intent = new Intent(getApplicationContext(),YOUR_SIGNIN_ACTIVITY.class);

 startActivity(intent);
}

现在，如果您点击buttonstrt或致电goSignInActivity()代码即可。您必须在menifest.xml文件中注册LoginActivity。

单击按钮时不会打开SignInActivity
