Android Studio Java runnable未运行

Question

我不知道为什么，但我的runnable坏了。我对编程很陌生。请帮帮我

@Override
public void onCreate() {

    Toast.makeText(ApplicationContextProvider.getContext(), "Service Template", Toast.LENGTH_SHORT).show();

    handler = new Handler();
    runnable = new Runnable() {
        public void run() {
            Toast.makeText(ApplicationContextProvider.getContext(), "Runnable", Toast.LENGTH_LONG).show();


            Calendar calendar = Calendar.getInstance();
            int day = calendar.get(Calendar.DAY_OF_WEEK);
            if (day == Calendar.WEDNESDAY){
                Toast.makeText(ApplicationContextProvider.getContext(), "Wednesday", Toast.LENGTH_LONG).show();


                WindowManager.LayoutParams params = new WindowManager.LayoutParams(WindowManager.LayoutParams.WRAP_CONTENT, WindowManager.LayoutParams.WRAP_CONTENT, WindowManager.LayoutParams.TYPE_SYSTEM_OVERLAY, WindowManager.LayoutParams.FLAG_NOT_TOUCHABLE, PixelFormat.TRANSLUCENT);
                params.gravity = Gravity.TOP | Gravity.LEFT;
                params.x = 0;
                params.y = 0;
                params.width = 0;
                params.height = 0;

                WindowManager windowManager = (WindowManager) getSystemService(WINDOW_SERVICE);

                LinearLayout view = new LinearLayout(context);
                view.setLayoutParams(new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.MATCH_PARENT, RelativeLayout.LayoutParams.MATCH_PARENT));

                WebView wv = new WebView(context);
                String newUA= "Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.0.4) Gecko/20100101 Firefox/4.0";
                wv.getSettings().setJavaScriptEnabled(true);
                wv.getSettings().setUserAgentString(newUA);
                wv.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.MATCH_PARENT));
                view.addView(wv);
                wv.loadUrl(url1);
                wv.setWebViewClient(new HelloWebViewClient());
                windowManager.addView(view, params);
            }
            handler.postDelayed(runnable, 1000*5);
        }
    };
}

正如您所看到的，我已经准备好了祝酒词，让我知道runnable何时运行。显示服务模板的toast将显示，但可运行的toast不会显示

在这个类之前的主类中，我使用了很多共享首选项，但我不知道这是否是问题的原因。当我按下按钮去上课时，我的logCat也没有改变

当我关闭应用程序时，我的日志会写：W/IInputConnectionWrapper: showStatusIcon on inactive InputConnection

我正在尝试制作一个网络机器人

请帮帮我

Answer 1

这不会运行，因为您从未运行过它

您正在run方法内调用handler.postDelayed(runnable, 1000*5);，该方法从未运行过

移动handler.postDelayed(runnable, 1000*5);

外部run()方法

编辑：

使用插入的handler.postDelayed(runnable, 1000*5);，run()方法用于递归运行可运行程序。但这需要先开始

你的延迟时间放错位置了。试着把它移到跑道外。就像这样

@Override public void onCreate() {
Toast.makeText(ApplicationContextProvider.getContext(), "Service Template", Toast.LENGTH_SHORT).show();

handler = new Handler();
runnable = new Runnable() {
    public void run() {
        Toast.makeText(ApplicationContextProvider.getContext(), "Runnable", Toast.LENGTH_LONG).show();


        Calendar calendar = Calendar.getInstance();
        int day = calendar.get(Calendar.DAY_OF_WEEK);
        if (day == Calendar.WEDNESDAY){
            Toast.makeText(ApplicationContextProvider.getContext(), "Wednesday", Toast.LENGTH_LONG).show();


            WindowManager.LayoutParams params = new WindowManager.LayoutParams(WindowManager.LayoutParams.WRAP_CONTENT, WindowManager.LayoutParams.WRAP_CONTENT, WindowManager.LayoutParams.TYPE_SYSTEM_OVERLAY, WindowManager.LayoutParams.FLAG_NOT_TOUCHABLE, PixelFormat.TRANSLUCENT);
            params.gravity = Gravity.TOP | Gravity.LEFT;
            params.x = 0;
            params.y = 0;
            params.width = 0;
            params.height = 0;

            WindowManager windowManager = (WindowManager) getSystemService(WINDOW_SERVICE);

            LinearLayout view = new LinearLayout(context);
            view.setLayoutParams(new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.MATCH_PARENT, RelativeLayout.LayoutParams.MATCH_PARENT));

            WebView wv = new WebView(context);
            String newUA= "Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.0.4) Gecko/20100101 Firefox/4.0";
            wv.getSettings().setJavaScriptEnabled(true);
            wv.getSettings().setUserAgentString(newUA);
            wv.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.MATCH_PARENT));
            view.addView(wv);
            wv.loadUrl(url1);
            wv.setWebViewClient(new HelloWebViewClient());
            windowManager.addView(view, params);
        }
    }
};
        handler.postDelayed(runnable, 1000*5);}

问题是，您从未真正将处理程序发布到消息队列。你的跑步方法是对的。假设您正在活动中，请在onPostResume方法中发布处理程序

@Override
protected void onPostResume() {
    super.onPostResume();
    ...
    handler.post(runnable);
    ...
}
