当我点击Activity btnFemale和Button btnMale时，我只想尝试打开另一个Button。现在btnfemale {{ 1}}效果很好，但Button btnMale无效。

Button

Answer 1

创建单独的侦听器，而不是另一个

server {
  listen 443 ssl;
  server_name my-sites.com;
  ssl_certificate /etc/nginx/ssl/my-sites.com/uni_my-sites.com.crt;
  ssl_certificate_key /etc/nginx/ssl/my-sites.com/my-sites.com.key;
  ssl_protocols TLSv1 TLSv1.1 TLSv1.2;

  client_max_body_size 30m;

  location / {
    proxy_pass http://my-backend.com;
    proxy_set_header Host $host;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header X-Forwarded-Proto $scheme;
  }
}

点击BtnFemale.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { Intent intent = new Intent(getApplicationContext(),ActivityTwo.class); startActivity(intent); } }); BtnMale.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v){ Intent intent = new Intent(getApplicationContext(),ActivityThree.class); startActivity(intent); } });时，您正在添加BtnMale的听众。

Answer 2

将您的代码更改为 BtnFemale.setOnClickListener（new View.OnClickListener（）{ @覆盖 public void onClick（查看v）{ Intent intent = new Intent（getApplicationContext（），ActivityTwo.class）; startActivity（意向）; } }）; BtnMale.setOnClickListener（new View.OnClickListener（）{ @覆盖 public void onClick（查看v）{ Intent intent = new Intent（getApplicationContext（），ActivityThree.class）; startActivity（意向）; } }）;

Answer 3

 Button BtnFemale = (Button)findViewById(R.id.btnFemale);
        final Button BtnMale = (Button) findViewById(R.id.btnMale);

        BtnFemale.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Intent intent = new Intent(getApplicationContext(), ActivityTwo.class);
                startActivity(intent);
            }
            });


                BtnMale.setOnClickListener(new View.OnClickListener() {
                    @Override
                    public void onClick(View v){

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

更正您的代码括号未妥善管理

为按钮创建单独的侦听器请点击以下链接。 Best practice for defining button events in android

$('#collapseDiv').on('shown.bs.collapse', function () {
       $(".glyphicon").removeClass("glyphicon-chevron-down").addClass("glyphicon-chevron-up");
    });

    $('#collapseDiv').on('hidden.bs.collapse', function () {
       $(".glyphicon").removeClass("glyphicon-chevron-up").addClass("glyphicon-chevron-down");
    });

打开另一个活动时出错？
