多个按钮OnClickListener没有做任何事情。(Multiple button OnClickListener not doing anything. (Using a switch))

 我正在尝试创建一个应用主页，这将引导我的其他一些应用创意。 主页由6个按钮组成，我希望它们在点击时可以指向各自的页面。 为了检查这些按钮是否有效，我使用过多士（一旦祝酒工作，我会将它们改为意图）。 
 
 这是我的代码，为了简化和缩短代码，我只在一个按钮后显示代码，但相同的代码适用于我的android工作室中的其他5个代码。 
 
 首先，XML： 
 
<Button
    android:id="@+id/spotify_button"
    android:text="Spotify Streamer"
    android:textAllCaps="true"
    android:layout_width="match_parent"
    android:layout_height="60dp" />
 
 在MainActivity中： 
 
public class MainActivity extends AppCompatActivity {


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        Button spotify = (Button)findViewById(R.id.spotify_button);


        spotify.setOnClickListener(buttonz);



    }

    private View.OnClickListener buttonz = new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            switch(v.getId()) {

                case R.id.spotify_button:
                    Toast.makeText(getApplicationContext(), "Text",
                    Toast.LENGTH_SHORT);
                    break;
 
 作为Java和Android的新手，这就是我理解代码的工作方式： 
 
 在onCreate部分，我创建了一个名为“spotify”的按钮，该按钮被强制转换为XML按钮。 然后我在这个按钮上设置一个名为“buttonz”的onClickListener。 一旦“计算机”看到它，它就会查找我制作的部分（View.OnClickListener），它看到它在点击时起作用，所以它认为“点击按钮时会做一些事情我们会点击这里点击但点击了哪个按钮？ ？它不知道，那就是切换到位的时候。一切似乎都联系起来所以我不知道为什么当我在手机上打开应用程序并点击按钮时没有任何反应？ 
 
 无论如何，如果有人能帮助我完成这项工作，我将非常感激。 提前致谢。 

I'm trying to make an app homepage that will lead on to some other of my app ideas. The homepage consists of 6 Buttons, and I want them to lead to their own individual pages when clicked on. To check if the buttons work, I have used toasts (Once the toasts work i'll change them into intents).
 
Here is my code, to simplify and shorten the code I've only shown the code following one button, but the same code applies for 5 others in my android studio.
 
First of all, XML:
 
<Button
    android:id="@+id/spotify_button"
    android:text="Spotify Streamer"
    android:textAllCaps="true"
    android:layout_width="match_parent"
    android:layout_height="60dp" />
 
And in the MainActivity:
 
public class MainActivity extends AppCompatActivity {


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        Button spotify = (Button)findViewById(R.id.spotify_button);


        spotify.setOnClickListener(buttonz);



    }

    private View.OnClickListener buttonz = new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            switch(v.getId()) {

                case R.id.spotify_button:
                    Toast.makeText(getApplicationContext(), "Text",
                    Toast.LENGTH_SHORT);
                    break;
 
As someone very new to Java and Android, this is how I understand the code works:
 
In the onCreate section, I create a button called "spotify" which is cast to the XML button. I then set an onClickListener called "buttonz" on this button. Once the "computer" sees this it looks for the section I made (View.OnClickListener), which sees that it works on click, so it thinks "do something when the button is clicked we will handle click here but which button clicked??? It doesn't know, and that's when the switch comes into place. Everything seems to link up so I don't know why when i open the app on my phone and click the button nothing happens?
 
Anyways, if someone could help me make this work I would be very grateful. Thanks in advance.
