EverythingDialogFragment

随着业务增加，各种各样的dialog样式需要实现，传统需要写的各种各样的dialog，一是不好维护，二是在多人开发的时候，每个人写的dialog会不同，导致代码复用差，因为基于这些原因，本人根据DialogFragment的优势，自定义了算是基类的DialogFragment，受个人经验和能力，代码上仍有不足之处，还请大佬们多多指教。

关于命名

本来想取一个BaseDialogFragment，但名字太普通了，所以必须要取个花里胡哨的名字，但又不能太高调，但又不能失内涵，然后我谷歌翻译很多词汇，终于找到Everything，哈哈，大伙别喷我。

public class EverythingDialogFragment extends DialogFragment {

private View mRootView;
private Dialog mDialog;
private Context mContext;
private float widthPercentSize;
private float heightPercentSize;
private int layoutResID;
private EverythingDialogHolder holder;
private int[] viewIds;
private int theme;
private boolean cancel;
private boolean touchOutside;
private int animations;

public static EverythingDialogFragment newInstance() {
EverythingDialogFragment fragment = new EverythingDialogFragment();
return fragment;
}

@Override
public void onActivityCreated(@Nullable Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
mDialog = getDialog();
if (mDialog != null) {
try {
mDialog.setOnDismissListener(null);
mDialog.setOnCancelListener(null);
} catch (Exception e) {
e.printStackTrace();
}
}
}

@Override
public void onAttach(Context context) {
super.onAttach(context);
mContext = context;
}

@Override
public void onCreate(@Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
if (theme != 0){
setStyle(DialogFragment.STYLE_NORMAL, theme);
}
}

@Nullable
@Override
public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
if (mRootView==null){
mRootView = inflater.inflate(layoutResID, container, false);
setDialogSize(widthPercentSize, heightPercentSize);
}
return mRootView;
}

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

holder = EverythingDialogHolder.create(mRootView,this);
if (viewConvertListener!=null){
viewConvertListener.convertView(holder,this);
}
if (holder!=null && viewIds!=null && viewIds.length>0){
holder.addChildClickListener(viewIds);
}

if (mDialog != null) {
mDialog.setCanceledOnTouchOutside(touchOutside);
mDialog.setOnKeyListener((dialog, keyCode, event) -> cancel);
Window window = mDialog.getWindow();
window.setWindowAnimations(animations);
}
}

/**

其他区域是否点击消失
@param touchOutside
@return
*/
public EverythingDialogFragment setCanceledOnTouchOutside(boolean touchOutside){
this.touchOutside=touchOutside;
return this;
}

public EverythingDialogFragment setWindowAnimations(@StyleRes int resId) {
this.animations=resId;
return this;
}

/**

屏蔽返回键
@param cancel
@return
*/
public EverythingDialogFragment setCanceledOnTouch(boolean cancel){
this.cancel=cancel;
return this;
}

/**

设置Style
@param theme
@return
*/
public EverythingDialogFragment setStyle(int theme){
this.theme=theme;
return this;
}

/**

设置布局
@param layoutResID
@return
*/
public EverythingDialogFragment setContentView(@LayoutRes int layoutResID) {
this.layoutResID = layoutResID;
return this;
}

/**

设置显示的宽
@param widthPercentSize
@return
*/
public EverythingDialogFragment setWidthPercentSize(float widthPercentSize) {
this.widthPercentSize = widthPercentSize;
return this;
}

/**

显示高
@param heightPercentSize
@return
*/
public EverythingDialogFragment setHeightPercentSize(float heightPercentSize) {
this.heightPercentSize = heightPercentSize;
return this;
}

private void setFragmentManager(FragmentManager manager) {
try {
manager.beginTransaction().remove(this).commitAllowingStateLoss();
super.show(manager, getClass().getSimpleName());
} catch (Exception e) {
e.printStackTrace();
}
}

public EverythingDialogFragment show(Object obj){
if (obj!=null){
if (obj instanceof FragmentActivity){
FragmentActivity activity = (FragmentActivity) obj;
setFragmentManager(activity.getSupportFragmentManager());
}else if (obj instanceof Fragment){
Fragment fragment = (Fragment) obj;
setFragmentManager(fragment.getFragmentManager());
}else {
throw new IllegalArgumentException(“not is FragmentManager”);
}

深知大多数Android工程师，想要提升技能，往往是自己摸索成长或者是报班学习，但对于培训机构动则几千的学费，着实压力不小。自己不成体系的自学效果低效又漫长，而且极易碰到天花板技术停滞不前！

因此收集整理了一份《2024年Android移动开发全套学习资料》，初衷也很简单，就是希望能够帮助到想自学提升又不知道该从何学起的朋友，同时减轻大家的负担。
