最近升级 appium 的 driver 从 uiautomator1.0 升到 uiautomator2.0，之前的 xpath 中部分使用不了
案例：
(//*[@text='' and @content-desc='start_pager' and @resource-id='com.suning.snmessenger:id/loading_item_view'])[1]
05-03 17:04:29.346 18582-19939/io.appium.uiautomator2.server E/appium: Element not found:

提交了 issue，跟 appium 的同学请教后，原因是@text=''导致的
修改 uiautomator server 源码
public AppiumResponse safeHandle(IHttpRequest request) {
try {
Logger.info("Find element command");
KnownElements ke = new KnownElements();
final JSONObject payload = getPayload(request);
final String method = payload.getString("strategy");
String selector = payload.getString("selector");
if (selector.contains("@text=''")) {
selector = selector.replace("@text=''", "not(boolean(string(@text)))");
}
if (selector.contains("@content-desc=''")) {
selector = selector.replace("@content-desc=''", "not(boolean(string(@content-desc)))");
}
if (selector.contains("@resource-id=''")) {
selector = selector.replace("@resource-id=''", "not(boolean(string(@resource-id)))");
}
final String contextId = payload.getString("context");
Logger.info(String.format("find element command using '%s' with selector '%s'.", method, selector));
final By by = new NativeAndroidBySelector().pickFrom(method, selector);
这样原来 ui1.0 设计的许多脚本就不用逐一修改了。
切到 ui2.0 后，如何点击弹窗的？分两个场景：
