i tried to setText"你好", but it didn't work, do you have any ideas about how to set chinese charactors?
UiObject chatBox = mDevice.findObject(new UiSelector().resourceId("com.tencent.mm:id/z4"));
if (chatBox.waitForExists(2000)==false) {
assertFalse("cannot find chatBox option", false);
return;
} else {
chatBox.click();
chatBox.getSelector().focused(true);
chatBox.setText("tell me a joke");
}
