TextView不更新 [英] TextView not updating

问题描述

使用处理程序类更新 TextView 中的文本时存在一个愚蠢的问题。我在Google地图中设置了自定义信息窗口。

  mMap.setInfoWindowAdapter（new GoogleMap.InfoWindowAdapter（）{
 @Override 
 public View getInfoWindow（Marker标记）{
返回null; 
} 
 
 @覆盖
 public View getInfoContents（最后标记标记）{
 //设置标记为最终** * 
 View v = getLayoutInflater（）。inflate（R.layout.my_layout，null）; 
 TextView name =（TextView）v.findViewById（R.id.name）; 
 $ b （MyItem mi：myItems）
 $ final TextView status =（TextView）v.findViewById（R.id.status）; 
 $ b $ {if（mi.getName ）.equals（marker.getTitle（）））{
 
 name.setText（mi.getName（））; //这个正常更新
 
 Handler handler = new Handler （）; 
 handler.postDelayed（new Runnable（）{
 @Override 
 public void run（）{
 //这个设置文本，但不会更新UI 
 status.setText（Text）; 
 
 //在这里我打电话给我的更新文本函数
 updateTv（status，Text）; 
 //刷新窗口*** 
 marker.showInfoWindow（）; 
 
} 
}，5000）; 
休息; 
} 
} 
 
 return v; 
} 
}）; 
} 
  

TextView 名称正在更新，而状态 TextView 只更新其内容，并且不在屏幕上直观更新。我试过无效， runOnUiThread（），但似乎没有任何工作。我知道解决方案可能非常明显，但我没有看到它。

感谢您提前给予帮助！

以下是我尝试runOnUiThread（）的方法。

 <$ c 
 $ b runOnUiThread（new Runnable（）{
 @Override 
 public void run（）{$ b $ public void updateTv（final TextView tv，final String s）{
 
 runOnUiThread b 
 tv.setText（s）; 
 
 tv.invalidate（）; 
 
} 
}）; 
 
  

我的XML：

 <？xml version =1.0encoding =utf-8？> 
< LinearLayout xmlns：android =http://schemas.android.com/apk/res/android
 android：orientation =vertical
 android：layout_width =wrap_content 
 android：layout_height =wrap_content> 
 
< TextView 
 android：layout_width =match_parent
 android：layout_height =wrap_content
 android：textAppearance =？android：attr / textAppearanceLarge
 android：text =Large Text
 android：id =@ + id / name
 android：layout_gravity =center
 android：gravity =center_horizo​​ntal
 android：padding =10dp/> 
 
 
< TextView 
 android：layout_width =match_parent
 android：layout_height =wrap_content
 android：textAppearance =？android：attr / textAppearanceSmall
 android：text =...
 android：id =@ + id / status
 android：gravity =center_horizo​​ntal/> 
 
< / LinearLayout> 
  

解决方案

我通过刷新窗口在上面的代码中调用命令注释并用***签名。我感谢clownba0t

解决方案

所以你试图从返回后更新视图， getInfoContents（）并且不能用作其实时视图，请参阅此。

有些东西可能正在调用：

  status.invalidate（）; 
  

I have a silly problem updating text in a TextView using a handler class. I'm setting custom Info window in Google Maps.

mMap.setInfoWindowAdapter(new GoogleMap.InfoWindowAdapter() {
            @Override
            public View getInfoWindow(Marker marker) {
                return null;
            }

            @Override
            public View getInfoContents(final Marker marker) {
                //setting marker as final***
                View v = getLayoutInflater().inflate(R.layout.my_layout, null);
                TextView name = (TextView) v.findViewById(R.id.name);


                final TextView status = (TextView) v.findViewById(R.id.status);

                for(MyItem mi : myItems){
                    if(mi.getName().equals(marker.getTitle())){

                        name.setText(mi.getName()); //This one updates normaly

                        Handler handler = new Handler();
                        handler.postDelayed(new Runnable() {
                            @Override
                            public void run() {
                                //this one sets the text, but doesnt update on UI
                                status.setText("Text"); 

                                //Here I call my update text function
                                updateTv(status, "Text");
                                //Refreshing the window***
                                marker.showInfoWindow();

                            }
                        }, 5000);
                        break;
                    }
                }

                return v;
            }
        });
    }

TextView "name" is updating normally, while "status" TextView is only updating its content and not updating visually on the screen. I've tried invalidating, runOnUiThread(), but nothing seems to work. I know the solution might be really obvious, but I don't see it.

Thank you for your help in advance!

EDIT

Here's how i tried runOnUiThread().

public void updateTv(final TextView tv, final String s){

        runOnUiThread(new Runnable() {
            @Override
            public void run() {

                tv.setText(s);

                tv.invalidate();

            }
        });
    }

My XML:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
              android:orientation="vertical"
              android:layout_width="wrap_content"
              android:layout_height="wrap_content">

    <TextView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:textAppearance="?android:attr/textAppearanceLarge"
        android:text="Large Text"
        android:id="@+id/name"
        android:layout_gravity="center"
        android:gravity="center_horizontal"
        android:padding="10dp"/>


    <TextView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:textAppearance="?android:attr/textAppearanceSmall"
        android:text="..."
        android:id="@+id/status"
        android:gravity="center_horizontal"/>

</LinearLayout>

SOLUTION

I refreshed my window by calling commands commented and signed with *** in the code above. My thanks goes to "clownba0t"

解决方案

So you are trying to update the view after it returned from getInfoContents() and that won't work as its not a live view, see this.

Something that might work is calling:

status.invalidate();
