先上两张图，后面补上代码

我们以前的写法是在需要显示模糊引导的地方，写一个布局，然后第一次使用的时候显示出来。但是这样做代码结构不清晰，所以我们有必要将这些View独立出来，写成一个自定义的View

public class ShowMemberTipsView extends BaseTipsView {

    @Bind(R.id.btn_sure)
    Button btnSure;
    @Bind(R.id.img_close)
    ImageView imgClose;

    private static final String UNIQUE_KEY = ShowMemberTipsView.class.getSimpleName();
    private Context mContext;

    public ShowMemberTipsView(Context context) {
        super(context);
        this.mContext = context;
        init();
    }

    public ShowMemberTipsView(Context context, AttributeSet attrs) {
        super(context, attrs);
        this.mContext = context;
        init();
    }

    public ShowMemberTipsView(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
        this.mContext = context;
        init();
    }

    @Override
    public String getUniquekey() {
        return UNIQUE_KEY;
    }

    private void init() {
        initLayoutParams();
        addStatusBarView();
        addContentView();
    }

    private void initLayoutParams() {
        LayoutParams lp = new LayoutParams(
                LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT);
        setOrientation(VERTICAL);
        setLayoutParams(lp);
    }

    private void addContentView() {
        View view = inflate(mContext, R.layout.view_show_member_tips, null);
        ButterKnife.bind(this,view);
        addView(view);
    }

    @OnClick(R.id.btn_sure)
    public void sure() {
        if (mOnSureListener != null) {
            mOnSureListener.onSure(ShowMemberTipsView.this);
        }
    }

    @OnClick(R.id.img_close)
    public void close() {
        if (mOnCloseListener != null) {
            mOnCloseListener.onClose(ShowMemberTipsView.this);
        }
    }
}

引用的布局：

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="#E6000000">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical">

        <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="@dimen/topbar_layout_width"
            android:layout_marginTop="120dp"
            android:orientation="horizontal">

            <RelativeLayout
                android:layout_width="0.0dip"
                android:layout_height="fill_parent"
                android:layout_gravity="center_vertical"
                android:layout_weight="1.0">

                <ImageView
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content"
                    android:layout_centerInParent="true"
                    android:src="@drawable/icon_more_mask_btn" />
            </RelativeLayout>

            <View
                android:layout_width="1.0px"
                android:layout_height="fill_parent"
                android:layout_marginBottom="10.0dip"
                android:layout_marginTop="10.0dip" />

            <View
                android:id="@+id/rl_task_center"
                android:layout_width="0.0dip"
                android:layout_height="fill_parent"
                android:layout_weight="1.0" />
        </LinearLayout>

        <ImageView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_gravity="center_horizontal"
            android:layout_marginTop="20dp"
            android:src="@drawable/icon_more_mask_text" />

        <Button
            android:id="@+id/btn_sure"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_gravity="center_horizontal"
            android:layout_marginTop="20dp"
            android:background="@drawable/icon_more_mask_level_btn" />

        <View
            android:layout_width="match_parent"
            android:layout_height="0dp"
            android:layout_weight="1"/>
    </LinearLayout>

    <ImageView
        android:id="@+id/img_close"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="right"
        android:layout_marginRight="20dp"
        android:layout_marginTop="20dp"
        android:padding="5dp"
        android:src="@drawable/icon_app_upgrade_close" />
</FrameLayout>

最后是一个BaseView，主要是封装一些公共的方法

public abstract class BaseTipsView extends LinearLayout {
    private static final String TAG = BaseTipsView.class.getSimpleName();
    private String mUniqueKey;
    protected OnCloseListener mOnCloseListener;
    protected OnSureListener mOnSureListener;

    public BaseTipsView(Context context) {
        super(context);
        init();
    }

    public BaseTipsView(Context context, AttributeSet attrs) {
        super(context, attrs);
        init();
    }

    public BaseTipsView(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
        init();
    }

    private void init() {
        mUniqueKey = getUniquekey();
        if (TextUtils.isEmpty(mUniqueKey)) {
            throw new IllegalArgumentException("Uniquekey must not empty!");
        }
        maskClick();
    }

    //获取状态
    protected void addStatusBarView() {
        View statusBarView = new View(getContext());
        statusBarView.setBackgroundColor(getContext().getResources().getColor(R.color.line_color));
        int statusBarHeight = getStatusBarHeight();
        LayoutParams lp = new LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, statusBarHeight);
        statusBarView.setLayoutParams(lp);
        addView(statusBarView);
    }

    public abstract String getUniquekey();

    private void maskClick() {
        this.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View v) {
                // 因此View背景透明，防止点击到此View后面的控件
            }
        });
    }

    public void show(final Activity activity) {
        if (!isMoreTipsShowed()) {
            addViewToDector(activity);
            setMoreTipsShowed(true);
        }
    }

    public void dismiss(final Activity activity) {
        removeViewFromDector(activity);
    }

    /**
     * 添加View到dectorView
     * @param activity
     */
    private void addViewToDector(final Activity activity) {
        ViewGroup dectorView = (ViewGroup) activity.getWindow().getDecorView();
        dectorView.addView(this);
    }

    /**
     * 从dectorView移出View
     * @param activity
     */
    private void removeViewFromDector(final Activity activity) {
        ViewGroup dectorView = (ViewGroup) activity.getWindow().getDecorView();
        dectorView.removeView(this);
    }

    public void setOnCloseListener(OnCloseListener onCloseListener) {
        this.mOnCloseListener = onCloseListener;
    }

    public void setOnSureListener(OnSureListener onSureListener) {
        this.mOnSureListener = onSureListener;
    }

    public interface OnCloseListener {
        public void onClose(BaseTipsView baseTipsView);
    }

    public interface OnSureListener {
        public void onSure(BaseTipsView baseTipsView);
    }

    protected boolean isMoreTipsShowed() {
        SharedPreferences sp = getContext().getSharedPreferences(TAG, Context.MODE_PRIVATE);
        return sp.getBoolean(mUniqueKey, false);
    }

    protected void setMoreTipsShowed(boolean isShowed) {
        SharedPreferences sp = getContext().getSharedPreferences(TAG, Context.MODE_PRIVATE);
        SharedPreferences.Editor editor = sp.edit();
        editor.putBoolean(mUniqueKey, isShowed);
        editor.commit();
    }

    public int getStatusBarHeight() {
        int result = 0;
        int resourceId = getResources().getIdentifier("status_bar_height", "dimen", "android");
        if (resourceId > 0) {
            result = getResources().getDimensionPixelSize(resourceId);
        }
        return result;
    }

}
