好的，所以我最近完成了一个 android 应用程序 - 我的第一个应用程序：D！- 因为它是一个付费应用程序，谷歌告诉我我必须添加许可的东西。这很好，花花公子，除了在过去的五个小时里我一直被它吓坏了。最后认为我对它有点了解并开始使用它，但是在我的模拟器中对其进行测试时，我提出了两个问题：
我正在使用 google API for 4.1，正如他们在开发者控制台上的方便的操作方法所指示的那样，但不管我总是最终提出我的连接错误对话框。代码在这里：
public void dontAllow(int reason) {
if(isFinishing()){
return;
}
displayResults("Access Denied");
if(reason==Policy.RETRY){
showDialog(DIALOG_RETRY);
}else{
showDialog(DIALOG_ERROR);
}
}
public void applicationError(int errorCode) {
dontAllow(0);
}
public void displayResults(String result){
}
并调用相应的对话框：
protected Dialog onCreateDialog(int id){
switch(id){
case DIALOG_RETRY:
Builder builder = new AlertDialog.Builder(this);
builder.setMessage("Connection Error: Retry?");
builder.setCancelable(true);
builder.setPositiveButton("Retry", new RetryOnClickListener());
builder.setNegativeButton("Cancel", new CancelOnClickListener());
AlertDialog dialog = builder.create();
dialog.show();
break;
case DIALOG_ERROR:
Builder builder1 = new AlertDialog.Builder(this);
builder1.setMessage("Would you like to purchase Landscape ID! ?");
builder1.setCancelable(true);
builder1.setPositiveButton("Yes!", new BuyOnClickListener());
builder1.setNegativeButton("No.", new CancelOnClickListener());
AlertDialog dialog1 = builder1.create();
dialog1.show();
break;
}
return super.onCreateDialog(id);
}
private final class RetryOnClickListener implements
DialogInterface.OnClickListener{
public void onClick(DialogInterface dialog, int which) {
checker.checkAccess(checkerCB);
}
}
private final class CancelOnClickListener implements
DialogInterface.OnClickListener{
public void onClick(DialogInterface dialog, int which) {
onDestroy();
finish();
}
}
private final class BuyOnClickListener implements
DialogInterface.OnClickListener{
public void onClick(DialogInterface dialog, int which) {
Intent open = new Intent(Intent.ACTION_VIEW);
open.setData(Uri.parse("market://details? id=com.mustaroenterprise.landscapeid"));
startActivity(open);
}
}
我的第一个问题：为什么它没有按照应有的方式连接到服务器？我按照他们的教程构建了我的测试设备。我已经翻了三遍了！
第二个问题：当我在模拟器上启动应用程序时，连接错误对话框显示正常。我点击重试，它的工作原理。我点击取消，它杀死了应用程序。但是，如果我只是在对话框之外单击窗口中的任何其他位置，它会关闭对话框并且应用程序可以正常工作。那有点违背了整个目的，是吗？我该怎么做……不是这样？
以防万一我是个白痴并且错误出在其他地方，这是整个班级：
