自定义对话框内消失的字段

Question

我试图用Dialog，2 xImageViews，3 xTextViews和2xRadioButtons创建自定义Button。当然我不能使它成为常规的Dialog（因为使用了各种各样的Views），所以我决定创建自定义layout和Class，它将负责设置它。一切似乎都很好，直到我建造它。 对话显示只有ImageView和第一个TextView但其他Views消失了。 应该是这样的： 多数民众赞成我的代码 - 布局：

类：

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（以我的拙见），但我不知道是否有什么不对或丢失，或者我不能用这种方式使用Dialog。如果这是正确的方法，那对我来说会很好，因为我可以用我的自定义版本替换我之前使用过的所有Dialogs，这会让app变得更好，更清晰。

那么你可以使用DialogFragment。

DialogCreator.java

public class DialogCreator extends DialogFragment {

    private static final String TASK_ID_KEY = "taskID";
    private static final String COORDINATOR_KEY = "isCoordinator";

    @Override
    public void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setCancelable(false);
        setStyle(DialogFragment.STYLE_NORMAL, R.style.FullScreenDialogStyle);
    }

    public static DialogCreator newInstance(String taskID, boolean isCoordinator) {
        DialogCreator creator = new DialogCreator();
        Bundle bundle = new Bundle();
        bundle.putString(TASK_ID_KEY, taskID);
        bundle.putBoolean(COORDINATOR_KEY, isCoordinator);
        creator.setArguments(bundle);
        return creator;
    }

    @Nullable
    @Override
    public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
        return inflater.inflate(R.layout.dialog, container, false);
    }

    @Override
    public void onViewCreated(@NonNull View view, @Nullable Bundle savedInstanceState) {
        super.onViewCreated(view, savedInstanceState);

        TextView task = view.findViewById(R.id.textView);
        TextView chooseOptionText = view.findViewById(R.id.textView2);
        Button cancelButton = view.findViewById(R.id.button);
        Button okButton = view.findViewById(R.id.button4);
        final RadioButton radioAccept = view.findViewById(R.id.radioButton);
        final RadioButton radioDecline = view.findViewById(R.id.radioButton2);

        final RadioButton redirect = view.findViewById(R.id.radioButton4);

        Bundle bundle = getArguments();
        if (bundle == null) return;
        if (!bundle.containsKey(TASK_ID_KEY) || !bundle.containsKey(COORDINATOR_KEY)) return;

        boolean isCoordinator = bundle.getBoolean(COORDINATOR_KEY);
        String taskID = bundle.getString(TASK_ID_KEY);
        if (!isCoordinator) redirect.setVisibility(View.GONE);

        task.setText("ID: " + taskID);
        chooseOptionText.setText("Choose option:");
        cancelButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                dismiss();
            }
        });
        okButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                if (radioAccept.isChecked()) {
                    Toast.makeText(requireContext(), "Accept", Toast.LENGTH_SHORT).show();
                }
                if (radioDecline.isChecked()) {
                    Toast.makeText(requireContext(), "Decline", Toast.LENGTH_SHORT).show();
                }
                if (redirect.getVisibility() != View.GONE) {
                    if (redirect.isChecked()) {
                        Toast.makeText(requireContext(), "Redirect", Toast.LENGTH_SHORT).show();
                    }
                }
            }
        });
    }

    @NonNull
    @Override
    public Dialog onCreateDialog(@Nullable Bundle savedInstanceState) {
        Dialog dialog = super.onCreateDialog(savedInstanceState);
        if (dialog.getWindow() != null) {
            dialog.getWindow().setLayout(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT);
        }
        return dialog;
    }
}

styles.xml中的FullScreenDialogStyle

<style name="FullScreenDialogStyle" parent="Theme.AppCompat.Dialog">
        <item name="android:windowNoTitle">true</item>
        <item name="android:windowFullscreen">false</item>
        <item name="android:windowIsFloating">false</item>
        <item name="android:windowBackground">@android:color/white</item>
</style>

在您的活动中：

DialogCreator.newInstance("taskID",true).show(getSupportFragmentManager(),"TAG")

Answer 2

尝试阅读this答案，了解如何使用自定义布局创建对话框。您正在使用函数showSwitchDialog来创建对话框，但我认为您应该从扩展Dialog类的类创建对话框，然后使用以下内容显示它：

CustomDialogClass cdd = new CustomDialogClass();
cdd.show();

从上面的链接。我尝试使用LinearLayout根标记​​重写您的布局文件，这可能是显示其他视图的问题。如果它没有解决问题，请尝试调整对话框的创建，如上面的答案所示。
