使用AlertDialog或MaterialAlertDialog

一个示例代码:

final AlertDialog dialogBuilder = new AlertDialog.Builder(this).create();
    LayoutInflater inflater = this.getLayoutInflater();
    View dialogView = inflater.inflate(R.layout.custom_dialog, null);

    final EditText editText = (EditText) dialogView.findViewById(R.id.edt_comment);
    Button button1 = (Button) dialogView.findViewById(R.id.buttonSubmit);
    Button button2 = (Button) dialogView.findViewById(R.id.buttonCancel);

    button2.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            dialogBuilder.dismiss();
        }
    });
    button1.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            // DO SOMETHINGS
            dialogBuilder.dismiss();
        }
    });

    dialogBuilder.setView(dialogView);
    dialogBuilder.show();
