java - OnClick 不触发？

Question

我是 android 的新手，在做一些简单的事情时遇到了麻烦!

这是一些基本代码:

主要 Activity :

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    //Lets go ahead and set our buttons up.
    ServerButton = (Button)this.findViewById(R.id.ServerButton);
    ClientButton = (Button)this.findViewById(R.id.ClientButton);
    BTServer = new BluetoothServerService(this, mHandler);      
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.main, menu);
    return true;
}
    public void ServerButtonClick(View v){
    Log.d("BLUETOOTH MAIN ACTIVITY", "It got here");
    BTServer.start();
}

private final Handler mHandler = new Handler(){
    @Override
    public void handleMessage(Message msg){
        switch (msg.what){
        case HANDLER_CHANGE_SERVER_STATUS:
            switch(msg.arg1){
            case SERVER_STATUS_OFF:
                CURRENT_SERVER_STATUS = SERVER_STATUS_OFF;
                //We should probably add some logging, and the change to the button
                break;
            case SERVER_STATUS_ON:
                CURRENT_SERVER_STATUS = SERVER_STATUS_ON;
                //Again lets add some logging, etc.
                break;
            case SERVER_STATUS_ON_CONNECTED:
                CURRENT_SERVER_STATUS = SERVER_STATUS_ON_CONNECTED;
                //Again lets add some logging, etc.
                break;
            }
        }
        return;
    }
};

我的 XML 看起来像这样:

<Button
    android:id="@+id/ServerButton"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentBottom="true"
    android:layout_alignParentLeft="true"
    android:layout_marginBottom="146dp"
    android:layout_marginLeft="64dp"
    android:text="Connect to Server" />

<Button
    android:id="@+id/ClientButton"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentTop="true"
    android:layout_centerHorizontal="true"
    android:layout_marginTop="28dp"
    android:text="Start Server" 
    android:onClick="ServerButtonClick"/>

在我的日志中，我看到日志说它创建了 BTServer 对象，但是当我单击该按钮时我无法显示任何日志。

有什么建议吗？

谢谢!

在 onCreate 方法中为 ClientButton 定义一个点击 Action

 ClientButton.setOnClickListener(new View.OnClickListener() {
             public void onClick(View v) {
                 // Perform action on click
             }
         });

也为 ServerButton 定义一个类似上面的点击 Action

 ServerButton.setOnClickListener(new View.OnClickListener() {
                 public void onClick(View v) {
                     // Perform action on click
                 }
             });
