我正在尝试在活动中调用对话框。每当我更改自动旋转已打开并且我已将其设为横向，然后将其恢复为纵向时，它会导航到先前的活动。请帮助我。请找到对话框的代码。

public class TransSuccessfullyDialog extends Dialog implements OnClickListener
    {

        public  TransSuccessfullyDialog(Context context)
        {

            super(context);

            requestWindowFeature(Window.FEATURE_NO_TITLE);

            if(statusString.equals("1")){

                setContentView(R.layout.transaction_complete);
                //@Override


                ImageView img = (ImageView) findViewById(R.id.imageView1);    
                //Bitmap src = null;

                Bitmap bmp = BitmapFactory.decodeFile("data/data/com.android.epaisa/logo.jpg");
                Bitmap resizedBitmap=Bitmap.createScaledBitmap(bmp, 50, 50, true);
                img.setImageBitmap(resizedBitmap);


                refNo=(TextView)findViewById(R.id.textView1);
                refNo.setText("Thank you!");

                                card=(TextView)findViewById(R.id.textView3);
                card.setText(" Number "+ RefNo);



                actfail_btn=(Button) findViewById(R.id.addfromcontactsbtn);
                actfail_btn.setOnClickListener(this);

            }

        }
        public void onBackPressed() {
            // Do as you please
        }
        public void onClick(View v) 
        {
            if(v==actfail_btn)
            {
startActivity(intent);

            }
        }

    }

这是 MessageBox 的一个示例。使用它或将其与您自己的 Dialog 进行比较并纠正您的问题：

import java.util.ArrayList;

import org.mabna.order.R;

import android.app.Activity;
import android.app.AlertDialog;
import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.ViewGroup;
import android.widget.Button;
import android.widget.LinearLayout;
import android.widget.TextView;
import android.widget.Toast;

public class MessageBox {

    static ArrayList<AlertDialog> arrAlertDialog = new ArrayList<AlertDialog>();
    static OnMyDialogResult mDialogResult; // the callback

    public enum MessageBoxState {
        OK, YesNo
    }

    public enum MessageBoxResult {
        OK, Cancel, Yes, No
    }

    public final static void show(final Activity parent, String title,
            String message, MessageBoxState state) {

        // if (alertDialog != null)
        // {

        // }

        AlertDialog.Builder builder;

您只需在清单中定义 android:screenOrientation 属性，如下所示。

<activity android:name=".YourActivity" android:screenOrientation="landscape"/>.
