警报对话框 - 如何实现取消和确定按钮

Question

我有这个警告对话框，它有这两个按钮（确定和取消）。我想知道如何实现它。

因此，当您单击取消按钮时，它应该会关闭警报对话框并 return 返回到我当前所在的片段。如果我单击“确定”按钮，它应该替换当前的警报对话框并将其放置在另一个对话框中。

这是我下面用于确认的代码。 java 文件；

public class confirmation extends DialogFragment {

@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {

    final AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
    LayoutInflater inf = getActivity().getLayoutInflater();
    final View theDIalog = inf.inflate(R.layout.example_xml, null);
    builder.setView(theDIalog);

AlertDialog dialog = builder.create();



    theDIalog.findViewById(R.id.makeaTransferOk).setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Toast.makeText(getActivity(), "Okay button is clicked", Toast.LENGTH_SHORT).show();
        }
    });


    theDIalog.findViewById(R.id.makeaTransferCancel).setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            dialog.dismiss();
        }
    });

    return dialog;
}
}

这是我的 example_xml;

代码

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#ffc0c0c0">

<Button
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:text="Cancel"
                android:id="@+id/makeaTransferCancel"/>

<Button
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:text="OK"
                android:id="@+id/makeaTransferOk"/>

</RelativeLayout>

有人能帮帮我吗

Answer 1

尝试使用此代码实现您上面提到的功能：

AlertDialog.Builder builder1 = new AlertDialog.Builder(context);
            builder1.setMessage("Write your message here.");
            builder1.setCancelable(true);
            builder1.setPositiveButton("Ok",
                    new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialog, int id) {
            //put your code that needed to be executed when okay is clicked
            dialog.cancel();


            }
            });
            builder1.setNegativeButton("Cancel",
                    new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialog, int id) {
                    dialog.cancel();
                }
            });

            AlertDialog alert11 = builder1.create();
            alert11.show();

builder.setPositiveButton(text, new View.OnClickListener() {

                            @Override
                            public void onClick(View arg0) {
                                // TODO Auto-generated method stub

                            }
                        }).setNegativeButton(text, new View.OnClickListener() {

                            @Override
                            public void onClick(View arg0) {
                                // TODO Auto-generated method stub

                            }
                        }).create();

    alertDialog.setTitle("Alert");
    alertDialog.setMessage("your message ");
    alertDialog.setButton(AlertDialog.BUTTON_POSITIVE, "OK",
            new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialog, int which) {
                    dialog.dismiss(); //<-- change it with ur code
                }
            } );
    alertDialog.setButton(AlertDialog.BUTTON_NEGATIVE, "Cancel",
            new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialog, int which) {
                    dialog.dismiss();
                }
            } );
