DialogFragment是一个提示框的类，今天写一下平时用到的自定义Dialog的方法：

设置Dialog的显示宽度与位置

@Override    public void onResume() {       Window window = getDialog().getWindow();        Point size = new Point();        Display display = window.getWindowManager().getDefaultDisplay();        display.getSize(size);        //set width=screenwidth*0.875 height=wrap_content        window.setLayout((int) (size.x * 0.875),        WindowManager.LayoutParams.WRAP_CONTENT);        //set dialog location center        window.setGravity(Gravity.CENTER);        // Call super onResume after sizing        super.onResume();    }

去除掉DialogFragment默认的标题栏

    @Override    public Dialog onCreateDialog(Bundle savedInstanceState) {        Dialog dialog = super.onCreateDialog(savedInstanceState);        dialog.getWindow().requestFeature(Window.FEATURE_NO_TITLE);        return dialog;    }

添加动画效果（Dialog的动画效果）

 @Override    public void onActivityCreated(Bundle savedInstanceState) {        super.onActivityCreated(savedInstanceState);        getDialog().getWindow().getAttributes().windowAnimations= R.style.CollectDialogAnimation;    }    <style name="CollectDialogAnimation">        //Dialog show的效果 slide_up可以自己定义(我都是百度的）        <item name="android:windowEnterAnimation">@anim/slide_up</item>        //Dialog dismiss的效果        <item name="android:windowExitAnimation">@anim/slide_down</item>    </style>

设置Dialog是否可以被取消

    @NonNull    @Override    public Dialog onCreateDialog(Bundle savedInstanceState) {        Dialog dialog = super.onCreateDialog(savedInstanceState);        dialog.getWindow().requestFeature(Window.FEATURE_NO_TITLE);        //设置为不可取消        dialog.setCancelable(false);        //设置为dialog外点击不可取消        dialog.setCanceledOnTouchOutside(false);        //设置点击返回键或搜索键不可取消        dialog.setOnKeyListener(new DialogInterface.OnKeyListener() {            @Override            public boolean onKey(DialogInterface dialog, int keyCode, KeyEvent event)            {                if (keyCode == KeyEvent.KEYCODE_SEARCH||keyCode==KeyEvent.KEYCODE_BACK)                {                    return true;                }                else                {                    return false; //默认返回 false                }            }        });        return dialog;    }

设置自定义layout

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

Layout事件的响应

//buttonClickListener是一个接口，初始化Dialog的时候可以设置，这样Dialog里面的点击就可以传给父界面处理@Override    public void onViewCreated(View view, @Nullable Bundle savedInstanceState) {        super.onViewCreated(view, savedInstanceState);        if (view != null) {            //a=view.findViewById(R.id.a);            findViews();            if (getArguments() != null)                btnA.setOnClickListener(new View.OnClickListener() {                    @Override                    public void onClick(View v) {                        if (buttonClickListener != null) {                            buttonClickListener.onLeftButtonClick();                            dismiss();                        }                    }                });                btnB.setOnClickListener(new View.OnClickListener() {                    @Override                    public void onClick(View v) {                        if (buttonClickListener != null) {                            buttonClickListener.onRightButtonClick();                            dismiss();                        }                    }                });            }        }    }

设置DialogFragment为圆角对话框

@Nullable    @Override    public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {        getDialog().getWindow().setBackgroundDrawableResource(R.drawable.dialog_circle);        return inflater.inflate(R.layout.dialog_validate_code, container, false);    }//DialogFragment //dialog_circle<shape xmlns:android="http://schemas.android.com/apk/res/android"    android:shape="rectangle">    <solid android:color="@color/light_white" />    <corners        android:bottomLeftRadius="10dp"        android:bottomRightRadius="10dp"        android:topLeftRadius="10dp"        android:topRightRadius="10dp"></corners></shape>

注：R.layout.dialog_validate_code中根Layout必须宽度必须是wrap_content,而且background属性不能设置

都没有写DialogFragment的基本用法，如果大家需要的话，请留言，谢谢。一个行走中的菜鸟，推荐大神带你飞系列:http://stay4it.com/，报我名字给优惠
