Uiautomator 2.0之UiWatcher类学习小记

@Test
public void testCase09() throws InterruptedException {

final UiObject2 ui = mDevice.findObject(By.text("短信"));
//注册监听器
mDevice.registerWatcher("testWatcher", new UiWatcher() {
@Override
public boolean checkForCondition() {
if(mDevice.hasObject(By.text("联系人"))){
ui.click();
Log.i("testWatcher", "监听器被触发了");
return true;
}
Log.i("testWatcher", "监听器未被触发");
return false;
}
});

//运行用例步骤
mDevice.wait(Until.findObject(By.text("写短信")), 2000);
UiObject2 btn = mDevice.findObject(By.text("写短信"));
btn.click();
Thread.sleep(2000);
mDevice.pressBack();

//重置监听器
mDevice.resetWatcherTriggers();
mDevice.wait(Until.findObject(By.text("写短信")), 2000);
btn.click();
Thread.sleep(2000);
mDevice.pressBack();
Log.i("testWatcher", "重置监听器成功");

//移除监听器
mDevice.removeWatcher("testWatcher");
Log.i("testWatcher", "移除监听器成功");
mDevice.wait(Until.findObject(By.text("写短信")), 2000);
btn.click();
Thread.sleep(2000);
