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; } }
