android UiAutomator在清除文本时遇到中文的解决办法

public void cleartext() throws UiObjectNotFoundException {
    String name = getUiObjextByResourceId("com.dianzhi.teacher.school:id/edit_content_change").getText();
    outputNotable(name.length());
    //如果光标在最后
    pressTimes(KeyEvent.KEYCODE_DEL, name.length());
    //如果光标在最开始
    pressTimes(KeyEvent.KEYCODE_FORWARD_DEL, name.length());
}

public void pressTimes(int keyCode, int times) {//对于一个按键按多次
    for(int i=0;i<times;i++){
        UiDevice.getInstance().pressKeyCode(keyCode);
    }
}
