一、DialogFragment类的实现

public class EditDialogFragment extends AppCompatDialogFragment {
    public static final String TAG_BASE = "TAG_BASE";
    private View root;
    private Button btnCancel, btnSubmit;
    private String addressId;
    private static OnSuccessListener mOnSuccessListener;
    private EditText etDeviceId, etAPIUrl, etPushUrl, etAppId, etAppKey, etTimeOut;
    private NetConfigBean mDataBean;

    public static EditDialogFragment newInstance(OnSuccessListener onSuccessListener) {
        Bundle args = new Bundle();
        EditDialogFragment fragment = new EditDialogFragment();
        fragment.setArguments(args);
        mOnSuccessListener = onSuccessListener;
        return fragment;
    }

    public static EditDialogFragment newInstance(NetConfigBean bean, OnSuccessListener onSuccessListener) {
        Bundle args = new Bundle();
        args.putSerializable(TAG_BASE, bean);
        EditDialogFragment fragment = new EditDialogFragment();
        fragment.setArguments(args);
        mOnSuccessListener = onSuccessListener;
        return fragment;
    }

    @Nullable
    @Override
    public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
        root = inflater.inflate(R.layout.dialog_fragment_edit, container, false);
        getDialog().getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
        initIntentData();
        initView();
        initListener();
        return root;
    }

    private void initIntentData() {
        Bundle arguments = getArguments();

            etTimeOut.setText(String.valueOf(mDataBean.timeOut));
        }
    }

    private void initListener() {
        btnSubmit.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                String deviceId = etDeviceId.getText().toString();
                String aPIUrl = etAPIUrl.getText().toString();

                    NetConfigBean bean = new NetConfigBean();
                    bean.osVersioin = mDataBean.osVersioin;
                    bean.deviceId = deviceId;
                    bean.aipServerUrl = aPIUrl;
                    bean.pushServerUrl = pushUrl;
                    bean.appId = appId;
                    bean.appKey = appKey;
                    bean.timeOut = Long.valueOf(timeOut);
                    bean.updateTime = mDataBean.updateTime;
                    bean.sel = mDataBean.sel;
                    bean.netType = mDataBean.netType;

                    dismiss();
                    if (mOnSuccessListener != null) {
                        mOnSuccessListener.onSuccess(bean);
                    }
                } else {
                    Toast.makeText(getContext(), "内容不能为空", Toast.LENGTH_SHORT).show();
                }
            }
        });
        btnCancel.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                dismiss();
            }
        });
    }


    public interface OnSuccessListener {
        void onSuccess(NetConfigBean bean);
    }

    @Override
    public void onDismiss(DialogInterface dialog) {
        super.onDismiss(dialog);

        Window win = getDialog().getWindow();
        win.setBackgroundDrawable(new ColorDrawable(getResources().getColor(R.color.transparent)));
        DisplayMetrics dm = new DisplayMetrics();
        getActivity().getWindowManager().getDefaultDisplay().getMetrics(dm);

        WindowManager.LayoutParams params = win.getAttributes();
        params.gravity = Gravity.CENTER;
        // 使用ViewGroup.LayoutParams，以便Dialog 宽度充满整个屏幕
        params.width = (int) (dm.widthPixels * 0.8);
        params.height = ViewGroup.LayoutParams.WRAP_CONTENT;
//        params.height = (int) (dm.heightPixels * 0.3);
        win.setAttributes(params);
    }


}

二、layout布局文件

<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="@drawable/shape_item_bg"
    android:focusable="true"
    android:focusableInTouchMode="true"
    android:padding="10dp">

    <androidx.constraintlayout.widget.Guideline
        android:id="@+id/guideline"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:orientation="vertical"
        app:layout_constraintGuide_percent="0.5" />

        android:text="编辑"
        android:textColor="@color/black"
        android:textSize="18dp"
        app:layout_constraintLeft_toLeftOf="parent"
        app:layout_constraintRight_toRightOf="parent"
        app:layout_constraintTop_toTopOf="parent" />

    <EditText
        android:id="@+id/etDeviceId"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginTop="8dp"
        android:hint="DeviceId"
        android:textSize="14dp"
        app:layout_constraintLeft_toLeftOf="parent"
        app:layout_constraintTop_toBottomOf="@id/tvTitle" />

    <EditText
        android:id="@+id/etAPIUrl"
        android:layout_width="match_parent"

        android:layout_marginTop="8dp"
        android:hint="APIUrl"
        android:textSize="14dp"
        app:layout_constraintLeft_toLeftOf="parent"
        app:layout_constraintTop_toBottomOf="@id/etDeviceId" />

    <EditText
        android:id="@+id/etPushUrl"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginTop="8dp"
        android:hint="PushUrl"
        android:textSize="14dp"
        app:layout_constraintLeft_toLeftOf="parent"
        app:layout_constraintTop_toBottomOf="@id/etAPIUrl" />


    <EditText
        android:id="@+id/etAppId"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginTop="8dp"
        android:hint="AppId"
        android:textSize="14dp"
        app:layout_constraintLeft_toLeftOf="parent"
        app:layout_constraintTop_toBottomOf="@id/etPushUrl" />

    <EditText
        android:id="@+id/etAppKey"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginTop="8dp"
        android:hint="AppKey"
        android:textSize="14dp"
        app:layout_constraintLeft_toLeftOf="parent"
        app:layout_constraintTop_toBottomOf="@id/etAppId" />

    <EditText
        android:id="@+id/etTimeOut"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginTop="8dp"
        android:hint="TimeOut(ms)"
        android:inputType="number"
        android:textSize="14dp"
        app:layout_constraintLeft_toLeftOf="parent"
        app:layout_constraintTop_toBottomOf="@id/etAppKey" />


    <Button
        android:id="@+id/btnSubmit"
        android:layout_width="wrap_content"
        android:layout_height="35dp"
        android:layout_marginTop="20dp"
        android:background="@color/theme"
        android:text="修改"
        android:textColor="@color/white"
        app:layout_constraintLeft_toLeftOf="parent"
        app:layout_constraintRight_toLeftOf="@id/guideline"
        app:layout_constraintTop_toBottomOf="@id/etTimeOut" />

    <Button
        android:id="@+id/btnCancel"
        android:layout_width="wrap_content"

        android:text="取消"
        app:layout_constraintLeft_toRightOf="@id/guideline"
        app:layout_constraintRight_toRightOf="parent"
        app:layout_constraintTop_toTopOf="@id/btnSubmit" />

</androidx.constraintlayout.widget.ConstraintLayout>

三、资源文件

shape_item_bg:

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle">
    <solid android:color="@color/white" />
    <corners android:radius="8dp" />
</shape>

colors:

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <color name="purple_200">#FFBB86FC</color>
    <color name="purple_500">#FF6200EE</color>
    <color name="purple_700">#FF3700B3</color>
    <color name="teal_200">#FF03DAC5</color>
    <color name="teal_700">#FF018786</color>
    <color name="black">#FF000000</color>
    <color name="black_aa">#aa000000</color>
    <color name="white">#FFFFFFFF</color>

    <color name="theme">#1676FE</color>
    <color name="darkTheme">#0F5ECF</color>
    <color name="color_1676FE">#1676FE</color>
    <color name="color_grey">#F5F5F5</color>
    <color name="transparent">#00000000</color>
</resources>

四、调用

 EditDialogFragment.newInstance(NetConfigBean.NetConfigDao2Bean(dao), new EditDialogFragment.OnSuccessListener() {
                                @Override
                                public void onSuccess(NetConfigBean bean) {
                                    if (settingModel.updateNetConfig(bean)) {
                                        Toast.makeText(mContext, "修改成功", Toast.LENGTH_SHORT).show();
                                       
                                    } else {
                                        Toast.makeText(mContext, "修改失败", Toast.LENGTH_SHORT).show();
                                    }
                                }
                            }).show(((AppCompatActivity) mContext).getSupportFragmentManager(), "editDialog");
