如何在自定义对话框中将文本从xml文件中的TextView提取到TexView中？

Question

I have a TextView in my .xml file and below that TextView I have a button. The text in TextView changes everytime when the app is running. I created a custom dialog so that when I press the button the custom dialog shows. In this custom dialog I also have a TextView and I want this TextView to take and dislplay data that is in my main TextView.

Here is my main.xml file

<TextView
        android:gravity="center"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:id="@+id/country"
        android:layout_marginTop="10dp"
        android:text="country"/>

And this is TextView in custom_dialog.xml file

<TextView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:id="@+id/get_country"
        android:text=""/>

Below is my MainActivity.class custom dialog in onCreate()

customDialog= new Dialog( this );
    customDialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
    customDialog.setContentView(R.layout.custom_dialog);
    customDialog.setCancelable( true );
    TextView textContry=(TextView)customDialog.findViewById(R.id.get_country);

I need this TextView in custom_dialog to take data in TextView of main.xml when the dialog shows.

您必须在自定义对话框textView中设置文本，方法是单击按钮时从主文本视图中获取文本。

    textContry.setText(textviewMain.getText().toString());
