WindowManager和Window都可以獲取根View掐场，只是獲取的root view不同莹规，前者是整個(gè)OS中唯一的一個(gè)窗口管理的windows颠悬，作為引導(dǎo)的話有點(diǎn)問題的诱担，并不適合做引導(dǎo)，那么看到了window里面也可以獲取根view--它是ViewGroup琼牧，可以嘗試在當(dāng)前activity中獲取DecorView往里面添加view的方式實(shí)現(xiàn)恢筝。使用方式：遮罩圖片若干就像下面數(shù)組似的，在要引導(dǎo)的activity的布局中的root節(jié)點(diǎn)添加id=“root_container”障陶，當(dāng)然你可以根據(jù)需要改
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/root_container"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
首先寫以供DecorView的管理類：
public class DecorViewGuideHelper {
private Activity activity;
private View rootView;
private List<View> coverIds;
private int current = 0;
private int length = 0;
private int CONTINUE = 0x1234;
public DecorViewGuideHelper(Activity activity, List<View> coverIds) {
this.activity = activity;
this.coverIds = coverIds;
this.rootView = activity.getWindow().getDecorView().findViewById(R.id.root_container);
SharePreferenceUtil.getInstance(activity).setGUIDId(4);
this.length = coverIds.size();
}
@SuppressLint("HandlerLeak")
Handler handler = new Handler(){
@Override
public void handleMessage(Message msg) {
switch (msg.what) {
case 0x1234:
current++;
display();
break;
default:
break;
}
}
};
public void display() {
final ViewParent viewParent = rootView.getParent();
if (viewParent instanceof FrameLayout) {
if (length > 0 && current < length) {
final FrameLayout container = (FrameLayout) viewParent;
coverIds.get(current).setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
container.removeView(coverIds.get(current));
handler.sendEmptyMessage(CONTINUE);
}
});
container.addView(coverIds.get(current));
}
}
}
}
組裝view數(shù)組
private void initGuid(LayoutInflater inflater){
guid=new ArrayList<>();
guid.add(inflater.inflate(R.layout.layout_guid1, null));
View guid2=inflater.inflate(R.layout.layout_guid2, null);
View lltop2=guid2.findViewById(lltop);
ViewGroup.LayoutParams para2;
para2 = lltop2.getLayoutParams();
para2.width = ScreenUtils.getScreenWidth(getActivity());
para2.height = para2.width*10/22;
lltop2.setLayoutParams(para2);
guid.add(guid2);
View guid3=inflater.inflate(R.layout.layout_guid3, null);
View lltop3=guid3.findViewById(lltop);
ViewGroup.LayoutParams para3;
para3 = lltop3.getLayoutParams();
para3.width = ScreenUtils.getScreenWidth(getActivity());
para3.height = para3.width*6/22;
lltop3.setLayoutParams(para3);
guid.add(guid3);
View guid4=inflater.inflate(R.layout.layout_guid4, null);
View lltop4=guid4.findViewById(lltop);
ViewGroup.LayoutParams para4;
para4 = lltop4.getLayoutParams();
para4.width = ScreenUtils.getScreenWidth(getActivity());
para4.height = para4.width*12/22;
lltop4.setLayoutParams(para4);
guid.add(guid4);
}
寫四個(gè)布局：
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#88000000"
android:orientation="vertical">
<RelativeLayout
android:layout_width="match_parent"
android:layout_marginTop="30dp"
android:layout_height="match_parent">
<ImageView
android:id="@+id/head"
android:layout_alignParentRight="true"
android:layout_width="52dp"
android:layout_height="52dp"
android:src="@mipmap/icon_circle_guild"/>
<ImageView
android:layout_below="@+id/head"
android:layout_centerHorizontal="true"
android:layout_marginTop="10dp"
android:layout_marginRight="20dp"
android:layout_width="229dp"
android:layout_height="505dp"
android:src="@mipmap/pic_font1" />
</RelativeLayout>
</LinearLayout>
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#88000000"
android:orientation="vertical" >
<View
android:id="@+id/lltop"
android:layout_width="match_parent"
android:layout_height="150dp"/>
<ImageView
android:layout_width="294dp"
android:layout_height="391dp"
android:layout_gravity="center_horizontal"
android:src="@mipmap/pic_font2"/>
</LinearLayout>
.......................
然后調(diào)用
private void showGuide() {
DecorViewGuideHelper helper = new DecorViewGuideHelper(getActivity(),guid);
helper.display();
}
效果如圖：
