</LinearLayout>

**MainActivity.java**

public class MainActivity extends FragmentActivity {

    private TextView txtDialogValue;
    private Button btnOpenDialog;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        txtDialogValue = (TextView) findViewById(R.id.txtDialogValue);

        btnOpenDialog = (Button) findViewById(R.id.btnOpenDialog);

        btnOpenDialog.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                customDialog(MainActivity.this,"Enter value","Ok",R.layout.custom_dialog,new CustomDialogClickListener() {
                    @Override
                    public void onClick(String input) {
                        txtDialogValue.setText(input);
                    }
                });
            }
        });

    }


    public void customDialog(final Context context,final String title,final String buttonCaption, final int layoutID,final CustomDialogClickListener target) {

        ((Activity)context).runOnUiThread(new Runnable() {

            @Override
            public void run() {

                final Dialog dialog = new Dialog(context,android.R.style.Theme_Translucent_NoTitleBar);
                dialog.setContentView(layoutID);

                final TextView txtHeader = (TextView) dialog
                        .findViewById(R.id.txtHeader);
                final EditText edtInput = (EditText) dialog
                        .findViewById(R.id.edtInput);
                final Button btnOk = (Button) dialog
                        .findViewById(R.id.btnOk);
                txtHeader.setText(title);
                btnOk.setText(buttonCaption);
                btnOk.setOnClickListener(new View.OnClickListener() {

                    @Override
                    public void onClick(View v) {
                        target.onClick(edtInput.getText().toString());
                        dialog.dismiss();
                    }
                });
                dialog.show();
            }
        });
    }

    interface CustomDialogClickListener{
        public void onClick(String input);
    }

}

Answer 2

Try this one:

  public void dialogBox(){

    Dialog mDialog = new Dialog(this.getActivity());
    mDialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
    mDialog.setContentView(R.layout.fragment_layout);
    mDialog.show();

   EditText mEditText = (EditText) findViewById(R.id.id_number_custom);
}

创建一个您需要展示的布局。
