b.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            win();
        }
 });

public void win(){
    TextView winName;
    Button home;
    winName = mDialog.findViewById(R.id.winnerName);
    home = mDialog.findViewById(R.id.homeButton);
    mDialog.getWindow().setBackgroundDrawable(new 
    ColorDrawable(Color.TRANSPARENT));
    mDialog.setContentView(R.layout.winpopup);
    .
    **winName = p1name; <----- pass value name**  <---When this line arrives, 
    the application will display a white screen and an error
    .
   // winName.setText("HELLO");
    home.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            **mDialog.dismiss(); <----- dialog close** <--- or When this line 
            arrives, the application will display a white screen and an error
        }
    });
