Question

我尝试用Dialog，2 x ImageView，3 x TextView和2x RadioButton s创建自定义Button。当然，我不能将其设置为常规的Dialog（由于使用了View种类繁多），所以我决定创建自定义layout和一个Class将负责全部设置。直到我构建它，一切似乎都很好。
对话框仅显示ImageView和前TextView，但其他View不见了。

应该看起来像这样：

班级：

public class DialogCreator extends Dialog {
    public DialogCreator(@NonNull Context context) {
        super(context);
    }

    public void showSwitchDialog(Context context, String taskID, boolean isCoordinator, View.OnClickListener posButtonClickListener){
        final Dialog dialog = new Dialog(context);
        dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
        dialog.setCancelable(false);

        dialog.setContentView(R.layout.dialog_switch_service);
        TextView task = dialog.findViewById(R.id.textView);
        TextView chooseOptionText = dialog.findViewById(R.id.textView2);
        Button cancelButton = dialog.findViewById(R.id.button);
        Button okButton = dialog.findViewById(R.id.button4);
        RadioButton redirect = dialog.findViewById(R.id.radioButton4);

        if(!isCoordinator) redirect.setVisibility(View.GONE);
        okButton.setOnClickListener(posButtonClickListener);

        task.setText("ID: " + taskID);
        chooseOptionText.setText("Choose option:");
        cancelButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                dialog.dismiss();
            }
        });
        dialog.show();

    }
}

方法调用（对话框显示）：

DialogCreator dc = new DialogCreator(MainScreenActivity.this);
                dc.showSwitchDialog(MainScreenActivity.this, "000000", true,  new View.OnClickListener() {
                    @Override
                    public void onClick(View v) {
                        RadioButton radioAccept = v.findViewById(R.id.radioButton);
                        RadioButton radioDecline = v.findViewById(R.id.radioButton2);
                        RadioButton radioRedirect = v.findViewById(R.id.radioButton4);

                        if(radioAccept.isChecked()){
                            Toast.makeText(MainScreenActivity.this, "Accept", Toast.LENGTH_SHORT).show();
                        }
                        if(radioDecline.isChecked()){
                            Toast.makeText(MainScreenActivity.this, "Decline", Toast.LENGTH_SHORT).show();
                        }
                        if(radioRedirect.getVisibility() != View.GONE){
                            if (radioRedirect.isChecked()){
                                Toast.makeText(MainScreenActivity.this, "Redirect", Toast.LENGTH_SHORT).show();
                            }
                        }

                    }
                });

一切似乎都很好（以我的愚见），但是我不知道是否存在某些错误或遗漏，或者我不能仅以此方式使用Dialog。如果这是正确的方法，那么对我来说太好了，因为我可以用自定义版本替换以前使用过的所有Dialog，这会使应用程序变得更好，更清晰。
