我正在尝试在一个活动中调用一个对话框。无论什么时候，我改变了自动旋转，我已经使它成为风景，然后在回到肖像时它导航到之前的活动。请帮我一样。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);
}
}
}

您只需在清单中定义android：screenOrientation属性，如下所示。
<activity android:name=".YourActivity" android:screenOrientation="landscape"/>.
