我有一个项目有时会遇到问题。
以下是问题所在：
UserInterfaceManager uiManager = new UserInterfaceManager(ConnectedDBManagerHost.this);
if (uiManager.showYesNoDialog(getString(R.string.are_you_sure_you_want_to_disconnect_the_current_database), getString(R.string.are_you_sure), false))
{
ConnectionsManager.connectedDatabase = null;
Intent intent = new Intent(this, MainActivity.class);
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(intent);
finish();
}
我得到的错误是：

我想我已经把它缩小到uiManager.showYesNoDialog()，如下所示：
public boolean showYesNoDialog(String message, String title, boolean isCancelable)
{
final Handler handler = new Handler()
{
@Override
public void handleMessage(Message mesg)
{
throw new RuntimeException();
}
};
AlertDialog.Builder builder = new AlertDialog.Builder(context);
builder.setCancelable(isCancelable);
builder.setTitle(title);
builder.setMessage(message)
.setPositiveButton("Yes", new DialogInterface.OnClickListener()
{
public void onClick(DialogInterface dialog, int which)
{
dialogResult = true;
handler.sendMessage(handler.obtainMessage());
}
})
.setNegativeButton("No", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
dialogResult = false;
handler.sendMessage(handler.obtainMessage());
}
});
AlertDialog alert = builder.create();
alert.show();
try
{
Looper.loop();
}
catch (RuntimeException ex)
{
Log.d("Dialog Error", ex.toString());
}
return dialogResult;
}
上面的方法在我的图书馆中使用，在这个特定的应用程序的许多地方和我们没有任何问题的另一个应用程序。
随着showYesNoDialog被调用我一直得到这个错误（虽然不是每次，但更多时候），但是如果我删除这个方法调用，只是做我不能复制它的意图东西所以我很确定showYesNoDialog方法是问题，但我不明白为什么它在这里有问题，而且没有其他地方。
有没有其他人经历过这样的事情，并且能够阐明我能做些什么来解决这个问题。
答案 0 :(得分：0)
从CommonsWare评论中得出这一点，Looper.loop是一种不太常见的做事方式。这是我在Android中完成的第一个方法之一，但我没有修复方法来进行回调。
在UserInterfaceManager类中，我添加了以下内容：
public interface IDialogResult
{
void returnResult(boolean result);
}
然后我按如下方式更改了方法：
public void showYesNoDialog(String message, String title, boolean isCancelable, final IDialogResult iDialogResult)
{
AlertDialog.Builder builder = new AlertDialog.Builder(context);
builder.setCancelable(isCancelable);
builder.setTitle(title);
builder.setMessage(message)
.setPositiveButton("Yes", new DialogInterface.OnClickListener()
{
public void onClick(DialogInterface dialog, int which)
{
iDialogResult.returnResult(true);
}
})
.setNegativeButton("No", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
iDialogResult.returnResult(false);
}
});
AlertDialog alert = builder.create();
alert.show();
}
该方法调用如下：
uiManager.showYesNoDialog(getString(R.string.are_you_sure_you_want_to_disconnect_the_current_database), getString(R.string.are_you_sure), false, new UserInterfaceManager.IDialogResult()
{
@Override
public void returnResult(boolean result)
{
if (result)
{
ConnectionsManager.connectedDatabase = null;
Intent intent = new Intent(ConnectedDBManagerHost.this, MainActivity.class);
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(intent);
finish();
}
}
});
