android studio上HierarchyViewer的使用实例
16lz
2021-01-23
使用方法：
1无法再真机运行，需要在模拟机运行
2app在manifest要添加
（1）<uses-permission android:name="android.permission.INTERNET"/>
（2）<application android:debugable=" true"
3在测试的activity中使用：
（1）添加三行代码：
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState); ViewServer.get(this).addWindow(this);
}
public void onDestroy() {
super.onDestroy(); ViewServer.get(this).removeWindow(this);
}
public void onResume() {
super.onResume(); ViewServer.get(this).setFocusedWindow(this);
}
（2）点击运行as项目，然后模拟器运行程序，
（3）tools--android--androiddevice monitor
(4)界面打开后，没有找到，搜索hierarachy view即可，本人亲测，没有问题
直接上使用的源码：
创建ViewServer.java类（拷贝过去就可以）：
