我想将Doorbell.io集成到我的应用程序中，但是我得到错误，我自己无法修复它。
在eclipse中我收到此错误：
The constructor Doorbell(new DialogInterface.OnClickListener(){}, int, String) is undefined
这是我的代码。任何人都可以弄清楚这里出了什么问题？
builder.setNegativeButton(R.string.rta_dialog_no, new OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
int appId = myID123; // Replace with your application's ID
String apiKey = "myAPIkey"; // Replace with your application's API key
Doorbell doorbellDialog = new Doorbell(this, appId, apiKey); // Create the Doorbell object
doorbellDialog.setEmail("myemail"); // Prepopulate the email address field
doorbellDialog.setName("Philip Manavopoulos"); // Set the name of the user (if known)
doorbellDialog.addProperty("loggedIn", true); // Optionally add some properties
doorbellDialog.addProperty("username", "whatisthis");
doorbellDialog.addProperty("loginCount", 123);
doorbellDialog.setEmailFieldVisibility(View.GONE); // Hide the email field, since we've filled it in already
doorbellDialog.setPoweredByVisibility(View.GONE); // Hide the "Powered by Doorbell.io" text
// Callback for when the dialog is shown
doorbellDialog.setOnShowCallback(new io.doorbell.android.callbacks.OnShowCallback() {
@Override
public void handle() {
Toast.makeText(context, "Dialog shown", Toast.LENGTH_LONG).show();
}
});
doorbellDialog.show();
setOptOut(context, true);
}
});

答案 0 :(得分：2)
从Doorbell.io website和开发人员的慷慨帮助看来，您使用的构造函数需要Activity作为第一个参数。在您提供的代码中，Doorbell对象在匿名DialogInterface.OnClickListener类中实例化，因此，在该范围内，this关键字引用该匿名类，而不是Activity。通过命名类来明确引用当前Activity。例如，如果您的Activity名为MainActivity：
Doorbell doorbellDialog = new Doorbell(MainActivity.this, appId, apiKey);
