Question

尝试调用此方法时出现错误：

        okHttpClient.newCall(request).enqueue(new Callback() {
        @Override
        public void onFailure(Call call, final IOException e) {

            runOnUiThread(new Runnable() {
                @Override
                public void run() {
                    showErrorAlert(e.toString());
                }
            });
        }

//The Method:

public void showErrorAlert(String error) {
    AlertDialog.Builder dialogBuilder = new AlertDialog.Builder(ProjectListActivity.this);

    dialogBuilder.setMessage("Hmm, there seems to be an error downloading the project list. " + error);
    dialogBuilder.setCancelable(true);

    dialogBuilder.setPositiveButton(
            "Okay",
            new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialog, int id) {
                    dialog.cancel();
                }
            });
    AlertDialog alert = dialogBuilder.create();
    alert.show();
}

因此，当呼叫失败时，它将立即崩溃，这是控制台中的输出：

                      at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:807)

是否可以通过错误调用错误？或可能是因为我尝试显示的错误类型。

谢谢。

Answer 1

var res = ResourceLoader.GetForCurrentView();
var deleteText = res.GetString("DeleteBlock/Text");
var confirmYes = res.GetString("ConfirmYes");

Answer 2

如异常消息所示，当前活动已完成，但是您试图显示一个对话框，其中包含已完成活动的上下文。由于对话框没有窗口显示android运行时会引发此异常。

使用活动isFinishing（）方法：

检查此活动是否正在完成中，这是因为您在该活动上调用了finish（）还是其他人已要求完成该活动。

if(!isFinishing())
showDialog();

Answer 3

它对我有用，如果您想使用它：

AlertDialog.Builder alertDialog = new AlertDialog.Builder(HelpAndSupport.this);
    alertDialog.setTitle("Confirm Sign out...");
    alertDialog.setMessage("Are you sure you want signout from Talentslist?");
    alertDialog.setPositiveButton("YES", new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface dialog, int which) {
            //you posive click code here
        }
    });

    alertDialog.setNegativeButton("NO", new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface dialog, int which) {
            dialog.cancel();
        }
    });
    alertDialog.show();

应用程序在显示对话框时崩溃
